The justification of the 4 genera that currently compose the class Pavlovophyceae is based on a low number of species and a relative paucity of available, traceable and referenced cultures. Previous integrative phylogeny work revealed strains that can refine and strengthen our knowledge of the genera in the class. The application of multiple light and electron microscopy techniques allowed us to prioritize the cytomorphological characters (pyrenoid, thylakoid, stigma, knob-scales, life stage / life cycle) used for the taxonomy of these algae and to describe two new species: Exanthemachrysis fresneliae Véron sp. nov. and Rebecca billardiae Véron sp. nov. Consequently, revisions of the two genera Exanthemachrysis Lepailleur emend. Véron and Rebecca Green emend. Véron were made. In addition, the genus Pavlova Butcher emend Véron is revised in the light of these characters. Particular emphasis is placed on the life stages and habitat of the species.
Cymatodera batleth new species (Coleoptera: Cleridae) is described from Honduras. It appears to belong to a group of Central American congeners that share similar facies and coloration, deeply emarginate elytral apices and elaborately modified male pygidia.

Minute aphids belonging to the species Myzus fataunae Shinji (Hemiptera: Aphididae) were found at a nursery in Seminole County, Florida. Morphological and molecular data support this determination. The Florida population only colonized species of Pilea Lindl. in our host range experiments. It did not colonize Fatoua villosa. Nakai. Likewise, it did not colonize tested common Florida species of Urticaceae other than Pilea spp. Myzus fataunae is adventive, and it appears to be established in the United States.

Novel data support validity of Phoxinus chrysoprasius (Pallas, 1814) (Actinopterygii, Leuciscidae)
(2023)
The common minnow species Cyprinus chrysoprasius, previously synonymised to Phoxinus phoxinus, was originally described from the Crimean Peninsula (Black Sea – Sea of Azov basin). A genetic analysis of the mitochondrial cytochrome oxydase 1 in the context of a phylogenetic study of European Phoxinus showed that it represents a distinct genetic clade and potentially a valid species. In the present study, we approach the issue following a broader, both genetic and morphological, study in order to check and support the validity of native Crimean Phoxinus under the earliest available name of the species: P. chrysoprasius. Our data demonstrate a reliable genetic distance of this minnow from geographically neighbouring clades and species, and a certain morphological distinctiveness. In order to determine the taxonomic concept of P. chrysoprasius, as a species involved in a genetically well-differentiated, but phenotypically poorly structured complex of east-European Phoxinus, a neotype for the species, based on topotypical material, is herein described and designated. The original type locality of the species is also clarified.
The present corrigendum corrects errors that occurred in: Zheng Y., Hu H., Chen D., Chen J., Zhang H. & Rasnitsyn A.P. 2021. New fossil records of Xyelidae (Hymenoptera) from the Middle Jurassic of Inner Mongolia, China. European Journal of Taxonomy 733: 146–159. https://doi.org/10.5852/ejt.2021.733.1229
Several phylogenetic studies have revealed that Murraya s. lat. is not monophyletic, suggesting that it should be split into two genera, namely Murraya s. str. and Bergera J.Koenig ex L. Here, the genus Bergera is comprehensively revised based on molecular and morphological data. The genus consists of 11 species in total, including all species previously placed in Murraya sect. Bergera and an additional species previously placed in Murraya sect. Murraya. Ten new combinations are proposed, namely Bergera alternifolia (Kurz) F.J.Mou comb. nov., B. crenulata (Turcz.) F.J.Mou comb. nov., B. euchrestifolia (Hayata) F.J.Mou comb. nov., B. glabra (Guillemin) F.J.Mou comb. nov., B. kwangsiensis (C.C.Huang) F.J.Mou comb. nov., B. macrophylla (C.C.Huang) F.J.Mou comb. nov., B. microphylla (Merr. & Chun) F.J.Mou comb. nov., B. siamensis (Craib) F.J.Mou comb. nov., B. stenocarpa (Drake) F.J.Mou comb. nov., and B. tetramera (C.C.Huang) F.J.Mou comb. nov. An identification key of the 11 species and morphological descriptions are provided, as well as illustrations of diagnostic characteristics. Phylogenetic relationships of the species in Bergera are discussed.
Specimens of munidid squat lobsters belonging to the genera Heteronida Baba & de Saint Laurent, 1996 and Torbenella Baba, 2008 were collected in scientific expeditions made by several French cruises along the southwestern Pacific. These specimens were identified as two species (one new) of Heteronida and six species (four new) of Torbenella. The present paper provides systematic accounts of the five new species, along with new locality records of known species shown by this material and color information where available. Molecular data is provided to support the systematic status of each new species. A key to species for each of the genera is also presented.
Neotropical Xiphocentronidae may have arrived in South America from Central America in the late Miocene or via the Greater Antilles land bridge during the Oligocene. This would give from 10 to 30 Mya of diversification of the family in South America. However, only 11 species were previously known from the Andean foothills. In this study, five new species are described from Peru, four of Xiphocentron (X. ashaninka sp. nov., X. harakbut sp. nov., X. matsigenka sp. nov., X. yine sp. nov.) and one of Machairocentron (M. amahuaca sp. nov.). The new species are most similar to species described from the Yungas of Argentina, and the Pacific dominion of Colombia and Venezuela. The association with species from the Pacific may suggest a species divergences prior to the major Andean uplift and the Amazon basin formation. The spine-like setae on the basal region of the inferior appendage of Xiphocentron were recognized as topologically homologous to the setal brushes on the ventral projection of Caenocentron. Furthermore, based on the morphology of male and female genitalia of Machairocentron, a mating position different from that described for Psychomyiidae is inferred.
Male cerci variability was used as the main source of information to separate taxonomic units in the genus Pseudochelidura. Based on these data it was considered that three species of Pseudochelidura coexisted in the Pyrenees: P. sinuata, P. minor and P. montuosa. However, our phylogeographic and phylogenetic analyses based on molecular data (mitochondrial cytb and nuclear ITS2) do not support those conclusions. Combining these analyses with morphological studies we concluded that: 1) the Pyrenees are inhabited by a single evolutionary unit: P. sinuata (Germar, 1825) (= P. minor Steinmann, 1979 syn. nov., = P. montuosa Steinmann, 1981 syn. nov.). 2) Cantabrian and Pyrenean populations are reciprocally monophyletic and morphologically diagnosable representing two independent evolutionary units: Pseudochelidura cantabrica Cuesta-Segura, Jurado-Angulo & García-París sp. nov. and P. sinuata. And, 3) their conservation status needs to be evaluated in the light of current taxonomic changes. We have shown that the use of male cerci for species identification is problematic. Patterns of variation possibly affected by sexual selection (e.g., intrapopulational variability) appear to be very difficult to separate from variation driven by natural selection or genetic drift (i.e., character divergence in geographical isolation). The large sequence divergence observed between Pyrenean and Cantabrian populations of Pseudochelidura suggest a lasting genetic and geographic isolation between them, rendering difficult to ascertain their phylogenetic relationships.
Based on morphological and molecular evidence, two new species of Silene are recognized and described here, S. penduliflora F.Jafari, Keshavarzi & Doostm. sp. nov. and S. thyrsiantha F.Jafari, Mirtadz. & Keshavarzi sp. nov. The newly discovered species are distributed in the central and southeastern parts of Iran, growing in rocky habitats. Relationships among these species and their close relatives are demonstrated using nrDNA ITS and cpDNA rps16 phylogenies. Silene ghahremaninejadii, S. parrowiana, and S. shahrudensis form a clade with these new species. A key to S. penduliflora and S. thyrsiantha and their close relatives is provided.

Based on molecular and morphological data of four specimens of Pareas Wagler, 1830 collected from the type locality of P. yunnanensis (Vogt, 1922), along with examination of the type specimens of P. yunnanensis, we revalidate this poorly known, secretive species. Furthermore, based on molecular and morphological lines of evidence we also describe a new species of Pareas from Xishuangbanna Prefecture, Yunnan Province, China. Morphologically, the new species closely resembles its sister species P. nigriceps Guo & Deng, 2009. However, the new species is divergent from the latter in cytochrome b mtDNA gene sequences, and can be distinguished from all congeners by the following combination of morphological characteristics: single preocular, postocular fused with subocular, loreal not bordering orbit, vertebral scales enlarged, 3–5 rows of mid-dorsal scales keeled at the middle of the body, ventral scales 160–171; subcaudals 62–64, dorsal surface of head solid black or reddish-brown, dark nuchal band present, iris brownish-black or reddish-brown.
The genus Lacronia Strand, 1942 is herein revised, and a maximum parsimony phylogenetic analysis of morphological characters (30 taxa, 115 characters, 2962 scorings) is performed to test its monophyly. As a result, Lacronia is herein made monophyletic by means of the inclusion of Discocyrtus boraceae B. Soares, 1942, Discocyrtus niger Mello-Leitão, 1923 and Discocyrtus tenuis Roewer, 1917. Lacronia including those species is the sister group of Discocyrtus s. str. inside the DRMN-clade, and should be removed from Pachylinae Sørensen, 1884, although without a new subfamilial assignment for now. Four new junior subjective synonyms are detected for the first time (Discocyrtus rarus B. Soares, 1944 = Discocyrtus fazi Piza, 1942 = Discocyrtus niger Mello-Leitão, 1923; Discocyrtus infelix Mello-Leitão, 1940 = Discocyrtus nigrolineatus Mello-Leitão, 1923 = Discocyrtus tenuis Roewer, 1917). Accordingly, the following new combinations are proposed: Lacronia boraceae (B. Soares, 1942) comb. nov., Lacronia nigra (Mello-Leitão, 1923) comb. nov. and Lacronia tenuis (B. Soares, 1942) comb. nov. Lacronia is endemic to the Atlantic province of Brazil, with verified records from the states of Rio de Janeiro, Santa Catarina and São Paulo. As a geographic note, the record of ‘D. fazi’ for Chile is here discussed and considered incorrect.
The Lasioglossum (Dialictus) gemmatum species complex, also known as the L. tegulare species group and the L. parvum species complex, is a very common, widespread, diverse, and recognisable lineage of sweat bees, containing 22 previously described species and several known undescribed species. The species were recently revised for the eastern Nearctic region and the Greater Antilles, but remain poorly known in the western Nearctic along with most other L. (Dialictus). These characteristics make it a prime candidate for revision in ongoing taxonomic work on the western Nearctic L. (Dialictus). Here we present the results of this revision, including 10 new species descriptions, one new synonymy, a preliminary phylogeny, and keys to known Nearctic species. Species of the eastern Nearctic and a few primarily Neotropical species which can occur in the Nearctic are also included. We report that the L. (D.) gemmatum species complex is likely a monophyletic group arising from the L. (D.) comulum group, but that the enlarged tegula has arisen independently in at least two other L. (Dialictus) lineages, and it contains multiple cases of allopatric speciation. The following species are described as new: Lasioglossum (Dialictus) angelicum sp. nov., L. (D.) deludens sp. nov., L. (D.) diabolicum sp. nov., L. (D.) eremum sp. nov., L. (D.) gloriosum sp. nov., L. (D.) indagator sp. nov., L. (D.) holzenthali sp. nov., L. (D.) magnitegula sp. nov., L. (D.) profundum sp. nov., and L. (D.) rufodeludens sp. nov. Previously undescribed males of L. (D.) perparvum (Ellis, 1914) and L. (D.) pseudotegulare (Cockerell, 1896) and the female of L. (D.) gaudiale (Sandhouse, 1924) are diagnosed and figured for the first time. Lasioglossum (Dialictus) hunteri (Crawford, 1932) is a new subjective junior synonym of L. (D.) ellisiae (Sandhouse, 1924). Pre-2022 specimen records of L. (D.) hunteri and L. (D.) tegulariforme (Crawford, 1907) are attributable to a heterogeneous mix of species, and records of L. (D.) perparvum are likely attributable to L. (D.) deludens.
Six new and four known species of the genus Axonchium Cobb, 1920 are described and illustrated from the Western Ghats of India. Axonchium indicum sp. nov. has a 1.2–1.4 mm long body, offset lip region, 8–9 µm long odontostyle, expanded part of pharynx 39–49 % of total neck length, anterior uterine sac 0.9–1.6 times the mid-body diameter long, and a bluntly conoid tail. Axonchium microspiculum sp. nov. has a 1.1–1.22 mm long body, offset lip region, 7–8 µm long odontostyle, 20–23 µm long spicules, two weakly developed ventromedian supplements, and obtusely rounded tail. Axonchium nilgiriense sp. nov. has a 1.4–1.6 mm long body, offset lip region, 8–9 µm long odontostyle, vagina strongly bent posteriad, 37–41 µm long spicules, 3–4 ventromedian supplements, and bluntly conoid tail. Axonchium paracingulatum sp. nov. has a 2.5–2.8 mm long body, offset lip region, 10–11 µm long odontostyle, vaginal lumen highly expanded in the middle, 69 µm long spicules, and broadly conoid tail with rounded terminus. Axonchium tropicum sp. nov. has a 1.7–2.0 mm long body, offset lip region, 11–12 µm long odontostyle, anterior uterine sac 2.3–4.0 times the mid-body diameter long, 40 µm long spicules, 4 widely spaced ventromedian supplements, and broadly rounded tail. Axonchium uniqum sp. nov. has a 1.7–2.0 mm long body, offset lip region, 10–11 µm long odontostyle, anterior uterine sac 2.5–2.8 times mid-body diameter long, 68 µm long and slender spicules, and broadly conoid tail. Axonchium nitidum, A. saccatum, A. transkeiense and A. vallum are redescribed based on specimens collected from several localities. A diagnostic key to the identification of the valid species of this genus is provided.
An updated list is given of 25 species of soft scale insects (Hemiptera: Coccidae) which have been intercepted on plants imported into South Korea during the period of 1996 to 2021. Information on the number of interceptions, host plants, distribution and origin of species intercepted at South Korean ports of entry is provided. In addition, data on intercepted species was analyzed to determine potential invasive species of soft scales that could threaten South Korean plants.

Thirteen new fossil eucnemid taxa (Coleoptera: Elateroidea) are described from amber deposits excavated from the vicinity of Santiago, Dominican Republic. Two new genera, Mioxylobius and Paleoquirsfeldia are described. The following 13 new species are described from Dominican amber: Mioxylobius bicolor, Balistica serrulata, Paleoquirsfeldia epicrana, Dyscharachthis dominicana, Idiotarsus poinari, Euryptychus antilliensis, Euryptychus hispaniolus, Plesiofornax caribica, Fornax dominicensis, Fornax serropalpoides, Dromaeolus argenteus, Nematodes miocenensis and Nematodes thoracicus. Each new species are both diagnosed and illustrated. Calyptocerus Guérin-Méneville and Lissantauga Poinar are shown to be congeneic, resulting in a new combination: Calyptocerus epicranis (Poinar, 2013). Summaries of fossil eucnemid discoveries, highlighting differing hypothesis of prehistoric Caribbean island formations/speciation, accounts of ancient Dominican Republic environmental conditions and Dominican Republic amber are provided.

To better understand the dung beetle (Coleoptera: Scarabaeidae: Scarabaeinae) biodiversity of Costa Rica and Panama, new synonyms, records, distributions, and updates are presented. This paper analyzes the distribution and taxonomy of Phanaeus olsoufieffi Balthasar, 1939 in Panama and establishes the following new subjective synonym: Phanaeus panamensis Moctezuma and Halffter, 2021 = Phanaeus olsoufieffi Balthasar, 1939. Color morphs of Phanaeus pyrois Bates, 1887 in Costa Rica are analyzed. The Costa Rican distribution of Onthophagus bidentatus Drapiez, 1819 and O. marginicollis Harold, 1880 is studied. Onthophagus bidentatus is recorded for Costa Rica for the first time. A population analysis of barcode mtDNA, color morphs, and morphological and genitalia characters for different body sizes of Onthophagus cyanellus is undertaken. An mtDNA barcode tree is presented to assess the molecular identity of O. cyanellus resulting in the reaffirmed subjective synonymy, Onthophagus mesoamericanus Zunino and Halffter, 1988 = O. cyanellus Bates, 1887.

Previously described subgenera of Dacne Latreille, 1797 (Coleoptera: Erotylidae) show character states and combinations implying closer relationships with genera other than with Dacne, suggesting “Dacne” is not monophyletic. These characters are briefly discussed along with the genera sharing the characters. To improve the current classification, the subgenera of Dacne are raised to generic status as: Afrodacne Delkeskamp, 1954, Ameridacne Skelley, 2009, and Xenodacne Boyle, 1956. A checklist of all species included in these genera is presented, updating generic combinations as needed.

En este trabajo se describe una nueva especie de Alurnus Fabricius (Coleoptera: Chrysomelidae), A. chocoensis Pardo y Constantino, con notable coloración rojo sangre en todo el cuerpo, excepto las hembras que presentan el pronoto de color negro. La nueva especie es una plaga importante del follaje en palma de chontaduro (Bactris gasipaes Kunth) en la costa pacífica de Colombia y es un endemismo propio de las selvas lluviosas de la región biogeografica del Chocó, en el occidente de Colombia. Se presentan apuntes sobre su biología y ecología.
Four new crane fly species of the subgenus Tipula (Vestiplex) Bezzi, 1924, T. (V.) medialobata sp. nov. (Yunnan), T. (V.) singularis sp. nov. (Yunnan), T. (V.) cibagouensis sp. nov. (Tibet) and T. (V.) paramonovi sp. nov. (Tibet) are described and illustrated. Redescription and detailed illustrations of T. (V.) nestor Alexander, 1934 are provided with first distributional record in mainland China.
A new genus of Sparianthinae spiders, Cuiambuca gen. nov., is proposed to include the type species, Cuiambuca vacabrava sp. nov. (♂♀), from Paraíba and Sergipe, C. aratangi sp. nov. (♂♀), from Paraíba and Pernambuco, and C. borborema sp. nov. (♀) from Alagoas, all in northeastern Brazil. The genus is remarkable in that it exhibits a partly sclerotized conductor, with a sclerotized base and a distal hyaline sheath, in the male palp, a keyhole-shaped median septum in the female epigyne as well as a gourd-shaped spermathecae and blind ending projection in the vulva. All species are described and illustrated and a distribution map is provided.
Late Holocene ostracods were recovered from marine sediments of the Chao Phraya delta at a whale-fall excavation site located fifteen kilometers on land in the Am Pang Subdistrict, Ban Paew District, Samut Sakhon Province, north of the Gulf of Thailand. Thirteen species belonging to seven genera are identified. The deposition environment of the succession is for the first time characterized. The ostracod assemblages suggest that the entire succession associated with the whale-fall deposited in a shallow marine environment such as estuary, bay, inner shelf, subtidal, under less than 20 meters water-depth, in brackish to normal salinity with high mud content and turbidity, on a muddy substrate. This analysis is an important step toward the first in-depth study of ostracods associated with modern and fossil shallow-water whale-falls.
Three new deep-sea species of Thyasiridae (Mollusca: Bivalvia) from the northwestern Pacific Ocean
(2023)
The Thyasiridae is one of the species-richest families in the abyssal and hadal zones of the northwestern Pacific Ocean. Many thyasirid species dominate benthic communities in terms of abundance and play an important role in the functioning of deep-sea ecosystems. Most of the thyasirid species in the region are new to science and have not been described. Based on the material collected from 1954 to 2016 by seven deep-sea expeditions, three new species of Thyasiridae (Parathyasira coani sp. nov., P. pauli sp. nov., and Thyasira kharkovensis sp. nov.) are described from the abyssal and hadal zones (3210–7540 m depth) of the Sea of Okhotsk, the Bering Sea, as well as the Kuril-Kamchatka and Japan trenches. The new species are remarkable among their congeners due to the combination of the following characters: an obliquely-rhomboidal shell with a weak and shallow posterior sulcus and a large prodissoconch with sculpture of lamellated folds. Comparisons with related species are provided.
Four new species of marine polycystidid microturbellarians (Platyhelminthes, Kalyptorhynchia) are described from Cuba and Panama. These species are Brachyrhynchoides ortizi sp. nov., Djeziraia adriani sp. nov., Phonorhynchoides lalanai sp. nov., and Sabulirhynchus ibarrae sp. nov. All species occur in Cuba, and P. lalanai sp. nov. was also retrieved from the Pacific coast of Panama. From the latter locality, we also report Sabulirhynchus axi Artois & Schockaert, 2000. All species are readily distinguished from their congeners by the morphology of the sclerotised structures of the male genital system. The prostatic stylet of B. ortizi sp. nov. is the shortest and widest known for Brachyrhynchoides. Djeziraia adriani sp. nov. can be recognized by its paired seminal vesicles and S-shaped prostate stylet. The prostatic stylet of P. lalanai sp. nov. is proximally twisted and the length proportion between its accessory and prostatic stylet is the largest among all known species of Phonorhynchoides. Sabulirhynchus axi and Sabulirhynchus ibarrae sp. nov. are morphologically similar, yet the latter species is unique due to the characteristic ridge in the middle of the proximally tubular prostatic stylet. With the data available today, a possible explanation of rhabdocoel biogeographic patterns across the Isthmus of Panama remains largely speculative.
A new genus of Lebinthina (Orthoptera: Gryllidae: Eneopterinae) is erected based on species from Maluka Islands near northern Sulawesi (Indonesia): Platybinthus gen. nov. This new genus currently consists of three species. Platybinthus punctatus (Brunner von Wattenwyl, 1898) gen. et comb. nov. from Halmahera Island is assigned as the type species. Platybinthus striolatus gen. et comb. nov., also from Halmahera Island, is redescribed. We also describe a new species: Platybinthus sandyi gen. et sp. nov. from Morotai Island.
Four new species of Coleoptera are described: Pentanodes clavatus new species, from Ecuador; Pentanodes baldwini new species, from Panama (Cerambycidae: Cerambycinae: Tillomorphini); Elytrimitatrix (Grossifemora) dilatata new species, from Mexico (Disteniidae) and Novantinoe falsa new species, from Mexico (Disteniidae). Taxonomical notes on Euderces cribellatus (Bates, 1885) (Tillomorphini) and Oreodera Audinet-Serville, 1835 (Lamiinae: Acrocinini) are provided. Additionally, new records are provided for Oreodera noguerai McCarty, 2001 (new state record), Adetus croton Heffern, Santos-Silva and Botero, 2019 (new country record), Icimauna sarauaia Martins and Galileo, 1991 (new country record), and Phoebe mexicana Bates, 1881 (new state record).

Analyses of whole genomic shotgun datasets, COI barcodes, morphology, and historical literature suggest that the following 13 butterfly species from the family Hesperiidae (Lepidoptera: Papilionoidea) in Texas, USA are distinct from their closest named relatives and therefore are described as new (type localities are given in parenthesis): Spicauda atelis Grishin, new species (Hidalgo Co., Mission), Urbanus (Urbanus) rickardi Grishin, new species (Hidalgo Co., nr. Madero), Urbanus (Urbanus) oplerorum Grishin, new species (Hidalgo Co., Mission/Madero), Telegonus tsongae Grishin, new species (Starr Co., Roma), Autochton caballo Grishin, new species (Hidalgo Co., 6 mi W of Hidalgo), Epargyreus fractigutta Grishin, new species (Hidalgo Co., McAllen), Aguna mcguirei Grishin, new species (Cameron Co., Brownsville), Polygonus pardus Grishin, new species (Hidalgo Co., McAllen), Arteurotia artistella Grishin, new species (Hidalgo Co., Mission), Heliopetes elonmuski Grishin, new species (Cameron Co., Boca Chica), Hesperia balcones Grishin, new species (Travis Co., Volente), Troyus fabulosus Grishin, new species (Hidalgo Co., Peñitas), and Lerema ochrius Grishin, new species (Hidalgo Co., nr. Relampago). Most of these species are known in the US almost exclusively from the Lower Rio Grande Valley in Texas. Nine of the holotypes were collected in 1971-1975, a banner period for butterfly species newly recorded from the Rio Grande Valley of Texas; five of them collected by William W. McGuire, and one by Nadine M. McGuire. At the time, these new species have been recorded under the names of their close relatives. A Neotype is designated for Papilio fulminator Sepp, [1841] (Suriname). Lectotypes are designated for Goniurus teleus Hübner, 1821 (unknown, likely in South America), Goniloba azul Reakirt, [1867] (Mexico: Veracruz) and Eudamus misitra Plötz, 1881 (Mexico). Several taxonomic changes are proposed.

Several nomenclatural changes for taxa in the firefly subfamily Luciolinae (Coleoptera: Lampyridae) are proposed. Evidence is presented to correct the year of description for Luciola dregei Motschulsky 1853 to Motschulsky 1854 when the name was ratified. We correct the authorities and years of descriptions for type species designations for the genera Delopleurus Motschulsky, 1853, and Delopyrus Motschulsky, 1853 to Motschulsky 1854 for both. All remaining taxa described as variations in the subfamily Luciolinae by McDermott (1966), are evaluated to subspecies with their availability determined based on ICZN (1999) Article 45.6.

Biclonuncaria recurvana, new species (Lepidoptera: Tortricidae: Polyorthini), is described and illustrated from Area de Conservación Guanacaste in northwestern Costa Rica. It is most similar to B. conica Razowski, 1993, from Mexico, but the two are easily distinguished by features of the male genitalia. Biclonuncaria recurvana has been reared (n = 12 specimens) from field-collected larvae feeding on the leaves of Dalbergia glomerata Hemsley (Fabaceae), consistent with the previously reported host plant for B. dalbergiae Razowski and Becker, 1993, which has been reared from Dalbergia in Brazil.

Relatively little is known about the taxonomy and ecology of deep-sea nematode species inhabiting cold seep habitats. The available data show that cold seep nematode communities are typically characterized by low diversity and are often dominated by a single species, although no nematode taxon appears to have a strong association with methane seepage. In July 2019, a research voyage to New Zealand’s Hikurangi Margin provided an opportunity to characterize the nematode species communities of New Zealand cold seeps, which had not been investigated until now. Here, six new species and two new nematode genera of the class Chromadorea are described from macrofauna cores obtained at three seep sites (Mungaroa, Glendhu, and Uruti South) on Hikurangi Margin from 1227 to 2077 m depth. The species described here represent a wide range of feeding groups, ranging from deposit feeders (Linhomoeus pycnocricus sp. nov., Deraionema barbatum gen. et sp. nov.) to microvores (Aulostomonema abyssum gen. et sp. nov., Aegialoalaimus magnus sp. nov.) and epigrowth feeders (Desmodora parapilosa sp. nov.). The diet of Siphonolaimus curtisensillus sp. nov., which is characterized by an unusual stylet-like feeding apparatus, remains to be determined, however the presence of several different feeding modes in the species described here indicates that a range of food sources are exploited by macrofaunal nematodes at the study sites. Desmodora, Linhomoeus, and Aegialoalaimus have been reported from cold seep habitats previously, however no records of Siphonolaimus from cold seeps could be found in the literature. Aulostomonema gen. nov. does not appear to have a close association with seeps, whilst Deraionema gen. nov. appears to be restricted to the centre of the seep sites where methane seepage is likely strongest. Ongoing work on the ecology and distribution of nematode communities at the Hikurangi Margin seep sites will help determine spatial patterns in abundance and species distributions in more detail, including the identification of any species/taxa with affinities with methane seepage.
A new genus Nipponoluciola Ballantyne, Kawashima, Jusoh & Suzuki is proposed and described from males, females and larvae for two species of Japanese fireflies (Coleoptera, Lampyridae, Luciolinae) which have aquatic larvae. The famous Genji-botaru, the Genji firefly, formerly Luciola cruciata Motschulsky, 1854, now stands under Nipponoluciola cruciata (Motschulsky) gen. et. comb. nov. It is proposed that the original designation of this species from Java was in error and that the species is only known from Japan. The lesser known Kumejima-botaru, formerly Luciola owadai Satô & Kimura, 1994, now stands under Nipponoluciola owadai (Satô & Kimura) gen. et comb. nov. A neotype for Luciola cruciata is designated. Keys to adult males and larvae of Luciolinae genera with aquatic larvae are given. An overview of the status of the genus Luciola s. str. is given. Supplementary file addresses 1. Mitogenome analyses of the Luciolinae; 2. List of species of Luciola s. str.; 3. List of Japanese Luciolinae; 4. The identity of Luciola lateralis Motschulsky.
The amerophidian snake radiation is a Late Cretaceous superfamily that encompasses two families: Aniliidae, pipe snakes, and Tropidophiidae, dwarf boas. We describe a new dwarf boa snake species, from the Tropidophiidae family, from the cloud forest in northeastern Ecuador. Tropidophis cacuangoae sp. nov. can be diagnosed from its congeners based on external and osteological morphology. The new species inhabits eastern tropical piedmont and lower evergreen montane forests, in the Amazon Tropical Rainforest biome, and is likely to be an Ecuadorian endemic. We also discuss the relationships of the new species with South American tropidophiids and provide a key to the identification of mainland South American dwarf boas.
A revision of the wild species in the genus Malus Mill. (Rosaceae) is presented based on numerical analyses and specimens from herbaria around the world, while cultivated species such as Malus domestica (Suckow) Borkh. are not included because of their complicated domestication history. Infra- and interspecific morphological variation and species delimitation are clarified based on Principal Component Analyses (PCA) and Cluster Analyses (UPGMA). We found that several morphological characters traditionally used to distinguish species have limited taxonomic value because of high phenotypic variation or plasticity. There is a substantial conflict between traditional morphological and genetic taxonomic concepts, and as a result species lineages are often morphologically indistinguishable. None of the analyses supports the recognition of infraspecific categories in Malus transitoria (Batalin) C.K.Schneid. and interspecific categories between Malus doumeri (Bois) A.Chev. and Malus leiocalyca S.Z.Huang. Based on our analyses, we recognize 26 wild species in the genus, and propose seven new synonymies.

The genera Trichrysis Lichtenstein, 1876 and Chrysidea Bischoff, 1910 from India are reviewed. A new species, Trichrysis poseidonia sp. nov. from India and Nepal is described. Trichrysis bengalensis (Mocsáry, 1889) is revalidated from the previous synonymy with T. lusca (Fabricius, 1804). Trichrysis inops (Gribodo, 1884) is recorded from India for the first time. The lectotype of Chrysis spectrum Wickwar, 1908 is designated. Chrysis mendicalis Cameron, 1897 is transferred from the genus Trichrysis to the genus Chrysidea. Keys and illustrations are provided for the identification of the eleven species of Trichrysis and the four species of Chrysidea so far known in the country, including a Sri Lankan species.
A new flower fly genus (Diptera, Syrphidae), Biema Huo & Zhao gen. nov. from China is described based on two new species: Biema wanglangensis Huo & Zhao gen. et sp. nov. (designated as type-species) and Biema qilianensis Huo & Liu gen. et sp. nov. The new genus can easily be distinguished by the following morphological features: head, mesonotum and scutellum black; postpronotum without pile; metasternum not reduced, posterior margin shallowly concave; katepisternum only with ventral pile patches; alula narrow, as wide as basal width of cell c; male postabdomen conspicuously more swollen than other segments, surstylus and postgonite complex, phallus unsegmented. The results of our Bayesian inference and Maximum Likelihood analysis based on sequences of the Cytochrome c oxidase subunit I (COI) gene, as well as the species delimitation tests, support the separation of Biema Huo & Zhao gen. nov. from its related taxa. Additionally, an identification key to the genera of the tribes Bacchini and Melanostomini occurring in China is provided.
Puparia of a new whitefly, Aleuroparadoxus marisae García-Ochaeta and Dubey, new species (Hemiptera: Aleyrodidae), collected on leaves of Brosimum alicastrum Sw. in Santa Ana, Petén, Guatemala, and on Pimenta dioica (L). Merr. in Calzada Mopán, Dolores, Petén are described and illustrated. Drawings of morphological structures and differential diagnosis of the puparium are provided, and differences from congeners are discussed. A key to puparia of the Aleuroparadoxus Quaintance and Baker species is included.

Lodevoisadia coheni gen. et sp. nov. is described as the ninth species of ‘Grylloblattodea’ from the middle Permian of the Salagou Formation, near Lodève town (France). It is currently not reasonable to place this species into a specific family, even though it seems to share most characters with the small family Tunguskapteridae. The lack of phylogenetic analysis and the current poor delineation of the majority of the grylloblattodean families (lacking synapomorphies) render any attribution of new taxa to a particular family often uncertain.
Elusive flaws are identified in techniques widely adopted to organize the Material Examined sections in taxonomic publications, mostly regarding the usage of the term ibidem and the nesting of information such as country and states. Logical errors are identified that prevent objective retrieval of the original information and can hinder or block its interpretation, even in case-by-case analyses. It is demonstrated that the free usage of ibidem in the sense of “same as previous except as follows” compromises the interpretation of data, characterizing bad practice. Solutions are proposed for the precise usage of both the term ibidem and the nesting technique. A new technique for organizing, compressing, and presenting information, called grid-setting, is described and evaluated. Its most notable practical effect is that the Material Examined section becomes literally a coded data sheet, which can be accurately converted back to spreadsheet format. In addition, the grid-setting technique was able to generate texts up to 30% shorter than those edited with the best-known traditional techniques. The new ideas and fixes are incorporated into a new software, flexible enough to process varied and unlimited data into largely user-defined texts, which remain nevertheless universal in their format and logical interpretation.
Metopiinae is a relatively large subfamily of Darwin wasps with a cosmopolitan distribution. Species of this subfamily can be distinguished by a convex, and mostly undivided face and clypeus. Among 113 species in 24 genera of the Oriental region, only 24 species in eight genera are reported from India. Here, we describe and illustrate a new genus, Soliga, based on collections made from the Western Ghats and Eastern Himalayas, two important biodiversity hotspots. The combination of absence of epicnemial carina on dorsolateral part of mesopleuron, absence of propodeal carinae and dorsal carinae of first metasomal tergite differentiates the new genus from other metopiine genera. An illustrated key to the Indo-Australian metopiine genera is provided along with comments on new generic placement and character variability of metopiines.
Gloydius is a widespread pitviper group occurring from Eastern Europe to Korea and Siberia, with only one known species, G. himalayanus (Günther, 1864), found south of the Himalayas. We provide combined genetic and morphological data for G. himalayanus from specimens collected from Himachal Pradesh, India. Bayesian Inference and Maximum Likelihood phylogenetic analysis were performed on four concatenated mitochondrial genes, along with a multi-locus coalescent analysis of these and five additional nuclear genes. Our results indicate that G. himalayanus from the Chamba Valley, in western Himachal Pradesh, are highly distinct from the remaining studied populations. Haplotype networks of each nuclear locus showed that G. himalayanus contains high haplotype diversity with low haplotype sharing between the Chamba Valley population and populations from further west. Principal component analysis and canonical variate analysis conducted on morphological data of live and museum specimens also highlight the morphological distinctiveness of the Chamba population and we herein describe this population as a new species, Gloydius chambensis sp. nov. Recent descriptions of other new species of snakes from this valley underscores its isolation and suggests that further herpetological investigation of the highly dissected landscapes of the western Himalayas is needed to assess the true diversity of the region.
During a recent investigation of ant-mimicking arthropods in Costa Rica, two new species of salticid spiders were discovered. Here, I provide descriptions of the two species, Myrmapana costaricaensis sp. nov. and Corcovetella galianoae sp. nov. The former species has two forms; the dark form resembles Neoponera ants, while the light form resembles Pseudomyrmex ants. Corcovetella galianoae resembles Camponotus ants.
This study presents the inventory of sea spiders (Pycnogonida) sampled during the Madibenthos Expedition in Martinique (West Indies). Species were discriminated leaning on morphological and molecular data. A total of 761 specimens are classified in 72 species, 16 genera and nine families. Thirteen new species are described: Ammothella dirbergi sp. nov., A. krappi sp. nov., Tanystylum boucheti sp. nov., T. ingrallis sp. nov., Ascorhynchus iguanarum sp. nov., Eurycyde kaiouti sp. nov., Nymphon dorlis sp. nov., N. ludovici sp. nov., N. martinicum sp. nov., N. timons sp. nov., Anoplodactylus madibenthos sp. nov., Pycnogonum cesairei sp. nov. and Rhynchothorax sidereus sp. nov. We describe a neotype for Anoplodactylus micros Bourdillon, 1955 from the type locality. Martinique now includes 79 species of sea spiders, mostly endemic to the Tropical Northwestern Atlantic, cosmopolitan or shared with the South America Atlantic coast. Some species are potentially introduced. However, our knowledge of the distribution of species found in Martinique is probably biased by the scarcity of diagnostic morphological characters. Also, nine potentially cryptic species (discriminated on genetic data alone), are identified, shedding light on the overlooked diversity of sea spiders in the Tropical Northwestern Atlantic. Therefore, we call for a more widespread use of barcoding in sea spiders.
The genus Andromma Simon, 1893 is revised. The type species A. aethiopicum Simon, 1893 (♂♀) and the other three known species, A. anochetorum Simon, 1909 (♂), A. bouvieri Fage, 1936 (♀) and A. raffrayi Simon, 1899 (♂♀), are redescribed. The types of the subspecies A. raffrayi inhacorense Lessert, 1936 were not examined. This subspecies is considered a synonym of the nominal species. Nineteen new species are described and illustrated: A. albinovani sp. nov. (♂♀), A. alvoculatum sp. nov. (♀), A. anacardium sp. nov. (♀), A. cyamos sp. nov. (♀), A. cycnotrachelos sp. nov. (♂♀), A. delphiurum sp. nov. (♂♀), A. deogratias sp. nov. (♂♀), A. dicranobelos sp. nov. (♂), A. didrepanum sp. nov. (♂), A. divinagraciae sp. nov. (♂♀), A. elephantactes sp. nov. (♀), A. ghesquierei sp. nov. (♂♀), A. heligmos sp. nov. (♀), A. helix sp. nov. (♀), A. juakalyi sp. nov. (♂), A. katangensis sp. nov. (♀), A. ophiophagum sp. nov. (♀), A. prosopion sp. nov. (♀) and A. velum sp. nov. (♂♀). The distribution of the species and their apparent commensalism with termites are discussed.
This paper describes new or little known Amphipoda collected from Hydrozoa, Bryozoa, Porifera or kelp along the Chilean fjord region. The following species have been found and most of them were redescribed and illustrated: Sunamphitoe femorata (Krøyer, 1845); Caprella cf. equilibra Say, 1818; Haplocheira barbimana robusta K.H. Barnard, 1932; Epimeria (Metepimeria) acanthurus (Schellenberg, 1931); Labriphimedia vespuccii K.H. Barnard, 1931; Leucothoe kawesqari Esquete & Aldea, 2015; Podocerus cf. danae (Stebbing, 1888); Ligulodactylus macrocheir (Schellenberg, 1926) and Torometopa cf. crassicornis (Schellenberg, 1931). One species in this contribution is new to science: Liouvillea rocagloria sp. nov.
Juga is a genus of freshwater snails distributed from northern Washington to central California. The taxonomy and classification of the genus has a long and complex history, driven mainly by the features of their highly variable shells. The number of recognized species has fluctuated from ~9 to 11; however, it has been claimed that the actual diversity may be three times that number. We here present a systematic revision using a recently published molecular phylogeny as a framework, which supported the interpretation that there are only nine valid species. Comprehensive review of type material and original descriptions for all available species-group names indicates that almost all species previously considered valid were para- or polyphyletic grades of organization in shell morphology. Most species previously suggested to be putatively new were confirmed to be morphological variants of species already described. Species accounts include complete synonymies and partial chresonymies; the shells and radulae are illustrated and described. Lectotypes are designated for Melania plicifera Lea, 1838, M. silicula Gould, 1847, and M. rudens Reeve, 1860. Three species, Juga caerulea sp. nov., J. canella sp. nov., and J. douglasi sp. nov., are described as new and one species is excluded from the genus. The subgenera Calibasis D.W. Taylor, 1966 and Idabasis D.W. Taylor, 1966 are synonymized with Juga.
Using an integrative approach (morphology of the adult and larvae, bioacoustics, osteology, karyotype, and molecular data), we described a new tetraploid species of Odontophrynus to the Mantiqueira mountain range, in southeastern Brazil. The data suggest that Odontophrynus toledoi sp. nov., O. juquinha and Odontophrynus sp. (aff. juquinha) comprise a clade with specimens distributed along three distinct mountain ranges in Brazil: Mantiqueira (O. toledoi sp. nov.) and Espinhaço (O. juquinha) mountains, both in southeastern Brazil, and Diamantina Plateau (O. aff. juquinha), in northeastern Brazil. The new species is morphologically similar and closely related to O. juquinha, but is distinguished in morphology (both adult and larval), karyotype (O. toledoi sp. nov. is tetraploid and O. juquinha is diploid), and corroborated by phylogenetic inferences. We also show that these species do not exchange haplotypes in the 16s gene. Furthermore, although the raw acoustic parameters of Odontophrynus toledoi sp. nov. and O. juquinha overlap at the limits of their ranges, we found a clear difference in the acoustic space structure.
Bureschia serbica sp. nov., is described from a cave in the Stara Planina Mt in Serbia as a second species in the genus. It is a troglobite amphibious species, predominantly aquatic like the nominal species of the genus, Bureschia bulgarica. The new species is adapted to amphibious life in running groundwater, unlike the nominal one that lives in subterranean lakes and ponds. Body structure changes, most noticeable the significant changes in the structure of the mouthparts, as a result of preadaptation in aquatic and amphibious Synocheta, are discussed.
New state records for 32 species of Mexican Cleridae (Coleoptera) are presented. In addition, 10 species of Cleridae are reported for Mexico for the first time (new country records). Cymatodera bezarki new species and Enoclerus sepultura new species are described from Chiapas, Mexico. Enoclerus primulus new species is described from Chiapas, Mexico and El Salvador.

The firefly species described by Carl Linnaeus in 1758 and 1767 (Coleoptera: Lampyridae) were checked to determine the actual dates of publication. Nine out of twelve species were originally described in 1758 and not in 1767 as published in the majority of firefly literature. Lampyris hespera Linnaeus, 1767 as a junior synonym of Aspisoma lampyris (Linnaeus, 1758) is established.

New taxonomic data on some species of Atherigona Rondani are provided. This is partly based on recently discovered types of A. laevigata (Loew), A. maculipennis Stein, A. magnipalpis Stein, A. nigrithorax Stein and A. subnigripes (Karsch), and partly on new material that has become available. Among this new material is a new species here described: Atherigona zongoi sp. nov. The newly discovered types of Atherigona nigrithorax Stein and A. subnigripes (Karsch) are redescribed. The status of a specimen of Coenosia humeralis found among material in the Smithsonian Institution and incorrectly labelled as the type of Atherigona humeralis is clarified. The puparium of A. varia (Meigen) is partially described for the first time. New records are given for several species and distribution is updated.
Two novel species of Russula (Russulaceae, Russulales), namely Russula indosenecis A.Ghosh, D.Chakr., K.Das & Buyck sp. nov. and R. pseudosenecis A.Ghosh, D.Chakr., K.Das & Buyck sp. nov. belonging to sect. Ingratae subg. Heterophyllidiae are proposed herein based on their morphological features and nrITS-based phylogenetic inferences. Both species belong to the Asian ʻR. punctipes-senecisʼ complex of sect. Ingratae. The acrid R. indosenecis was collected from subalpine forests associated with Abies densa, whereas the mild R. pseudosenecis associates with tropical forests dominated by Shorea robusta. Both species are distinct from the other species of this species complex in nrITS sequence data and from all other known species in subg. Heterophyllidiae in the strong amyloidity of their suprahilar spot.
The description in 1891 of the sea pen genus Gyrophyllum Studer, 1891 and also the type species G. hirondellei Studer, 1891 was based on a single colony collected in the Azores Archipelago. During the 19th and 20th centuries, the family placement of this genus became controversial as the set of morphological features present in Gyrophyllum could justify its assignation to both the families Pennatulidae Ehrenberg, 1834 and Pteroeididae Kölliker, 1880. Deliberations over this intermediate set of characters finally ended in the reunification of the genera and species of both families under Pennatulidae by principle of priority. The use of molecular sources of information based on a series of sequencing techniques presents a different but promising phylogenetic scenario in order to go further in the understanding of pennatulacean systematics. In this paper, a complementary morphological and molecular study (multiloci sequences with three mitochondrial and one nuclear markers) based mainly on newly collected material is carried out. This study re-confirms from a molecular point of view previously published results that indicate the position of Gyrophyllum as being distant from Pennatula Linnaeus, 1758 and Pteroeides Herklots, 1858 (type genera of the families Pennatulidae and Pteroeididae, respectively). This fact together with the results of a detailed morphological examination strongly supports the placement of the enigmatic genus Gyrophyllum in a separate family: Gyrophyllidae fam. nov. and resolves the nomenclatural uncertainty at family level for this genus. Moreover, the characters previously considered useful in the distinction of the two currently recognised species G. hirondellei in the Atlantic and G. sibogae Hickson, 1916 in the Indo-western Pacific are revisited.
The hypnorum-complex of bumblebees (in the genus Bombus Latreille, 1802) has been interpreted as consisting of a single widespread Old-World species, Bombus hypnorum (Linnaeus, 1758) s. lat., and its closely similar sister species in the New World, B. perplexus Cresson, 1863. We examined barcodes for evidence of species’ gene coalescents within this species complex, using the closely related vagans-group to help calibrate Poisson-tree-process models to a level of branching appropriate for discovering species. The results support seven candidate species within the hypnorum-complex (Bombus taiwanensis Williams, Sung, Lin & Lu, 2022, B. wolongensis Williams, Ren & Xie sp. nov., B. bryorum Richards, 1930, B. hypnorum, B. koropokkrus Sakagami & Ishikawa, 1972, and B. hengduanensis Williams, Ren & Xie sp. nov., plus B. perplexus), which are comparable in status to the currently accepted species of the vagans-group. Morphological corroboration of the coalescent candidate species is subtle but supports the gene coalescents if these candidates are considered near-cryptic species.
A new genus and new species of potamid crab, Gurumon gurumayum gen. et sp. nov., are described from the Arunachal Pradesh State of northeastern India. Gurumon gen. nov. has affinities with Abormon Mitra, Pati & Ng, 2021, Pararanguna Dai & Chen, 1985, and some species of Potamiscus Alcock, 1909, but the new genus can easily be differentiated from them mainly by its low external orbital angle, the relatively stouter exopod of the third maxilliped, and the relatively broader male pleonal somite 6. Their male first gonopods are also different from each other. Counting Gurumon gurumayum gen. et sp. nov., India is currently known for ten genera and 24 species of potamiscine freshwater crabs, and Arunachal Pradesh for eight genera and 11 species of these crabs. The current nomenclatural problems with Potamiscus are also discussed.
Six new species of Zaischnopsis Ashmead (Hymenoptera: Eupelmidae) from China are described, Zaischnopsis covid Jiang & Peng sp. nov., Zaischnopsis fuscolivida Tang & Peng sp. nov., Zaischnopsis lii Jiang & Peng sp. nov., Zaischnopsis pacis Jiang & Peng sp. nov., Zaischnopsis campaniformis Tang & Peng sp. nov., and Zaischnopsis zhongi Jiang & Peng sp. nov. All the new species are described and illustrated based on females, and partial mitochondrial cytochrome oxidase subunit I (COI) sequences are provided for the six new species as well as for the previously described Z. fumosa Peng & Xiang. Females of all the species of Zaischnopsis recorded from China are differentiated in a key.
The genus Pareucamptonyx Olmi, 1991 is endemic to the New World and comprises three described species, two from the Neotropical region and one from the Nearctic. Here is presented the first revision of species of Pareucamptonyx from the Neotropical region, including four new species described from Brazil: P. albopictus Martins sp. nov., P. kumagaiae Martins sp. nov., P. niger Martins sp. nov. and P. paranaensis Martins sp. nov. Detailed illustrations, distribution map, and key to females are provided, as well as a revised diagnosis of the genus and notes about the method of collection. Additionally, new distribution records for P. townesi (Olmi, 1984) are reported.
Four new species of the braconid wasp genus Hecabolus Curtis, 1834 (Doryctinae Foerster, 1863) are described for the Neotropical region in south and southwestern Brazil: H. acutus sp. nov., H. chrisaxeli sp. nov., H. gavinbroadi sp. nov., and H. transversalis sp. nov. We also report the morphological variation of females and males of H. mexicanus Zaldívar-Riverón & Belokobylskij, 2009, originally described based on a single female, and provide its first precise geographical distribution records. An updated key to the 13 described species of Hecabolus is provided.
First host record, prey transport, and burrow excavation are described for Hesperopompilus sp., an undescribed, rare spider wasp (Hymenoptera: Pompilidae) from Texas. Taxonomic, ecological, and behavioral examination of the genus subsequently led to an investigation of the previously related Perissopompilus Evans and Xerochares Evans. Taxonomic, host preference, nesting behavior, and phylogenomic relationships of the three taxa are discussed along with those of Xenopompilus Evans. The molecular connection of Perissopompilus and Allochares Banks is supported by their common use of host species of Filistatidae.

Host records and nesting behavior of the Nearctic trapdoor spider-hunting spider wasps (Hymenoptera: Pompilidae) Calopompilus Ashmead and Priocnemissus Haupt (Pepsinae: Pepsini) and Aporus Spinola and Psorthaspis Banks (Pompilinae: Aporini) are reviewed, investigated, compared, and discussed. First time incidental trapdoor spider host records for Priocnemis (Priocnemissus) minorata Banks (Pepsinae: Pepsini), Anoplius (Lophopompilus) carolina (Banks) (Pompilinae: Pompilini), and Notocyphus dorsalis dorsalis Cresson (Notocyphinae: Notocyphini) are included, although they are not typical trapdoor spiderhunting spider wasp species. The Palearctic Aporus (Aporus) unicolor Spinola, A. (Aporus) bicolor Spinola and A. (Aporus) planiceps (Latreille) are referenced for comparison with Nearctic Aporus sensu stricto. Early 20th century papers on species of Aporus and Psorthaspis are revived. New information on nesting behavior of Nearctic trapdoor spider-hunting spider wasps is described and first host trapdoor spider records for Psorthaspis formosa (Smith), P. legata (Cresson) and P. mariae (Cresson) are documented. Potential Pompilidae species in the genera Calopompilus and Aporus are suggested for host trapdoor spider remains found in burrows with spider wasp eggs, larvae and cocoons (pupae) based on geographic distribution, habitat, spider species, trapdoor and burrow structure, wasp cocoon size, and wasp congeneric host records.

The subfamily Carventinae (Heteroptera: Aradidae) is revised for New Zealand. Eight genera and fifteen species are recognized. One genus and six species are described as new: Carventaptera hallae Larivière and Larochelle new species, Lissaptera heissi Larivière and Larochelle new species, Modicarventus kirmani Larivière and Larochelle new species, Neocarventus montanus Larivière and Larochelle new species, Neocarventus northlandicus Larivière and Larochelle new species, Neocarventus potterae Larivière and Larochelle new species, Tuataraptera Larivière and Larochelle new genus. One new combination is established: Neocarventus uncus Kirman, 1989 = Tuataraptera unca (Kirman, 1989). One new synonymy is made: Leuraptera yakasi Heiss, 1990 = Leuraptera zealandica Usinger and Matsuda, 1959. A revision of al taxa is provided. Descriptions, identification keys, illustrations of male genitalia, habitus photos, distributional data and maps are given. Extensive information on biology is included for each species.
