The linyphiid spiders Tenuiphantes zelatus (Zorsch, 1937), T. zibus (Zorsch, 1937), and Centromerus mariannae sp. nov. are diagnosed, described or redescribed and illustrated, including the previously undescribed female of T. zibus. All are common species of the Pacific Northwest of North America but were previously inadequately described (T. zelatus and T. zibus) or illustrated only but not described or named (C. mariannae).
Serratichneumon Riedel & Sheng gen. nov. and Serratichneumon maculatus Sheng & Riedel gen. et sp. nov. belonging to the tribe Ichneumonini of subfamily Ichneumoninae (Hymenoptera: Ichneumonidae), collected in the Oriental Region (China, Vietnam, and Indonesia), are described and illustrated. The new genus is placed in Tereshkin’s key to the Palaearctic genera of the subtribe Amblytelina, and compared with similar genera, Hepiopelmus Wesmael, 1845, and Tricholabus Thomson, 1894.
Four new species of Ommatius Wiedemann, the female of O. stramineus Scarbrough, and the male of 0. nigellus Scarbrough from Hispaniola are described. A lectotype for O. gwenae Scarbrough and a neotype for O. cinnamomeus are selected. Notes of previously named species, new records, illustrations of terminalia, and a key to the species are included.
Martensina thailandica gen. et sp. nov., a freshwater ostracod species representing a new subfamily, Martensininae subfam. nov., in the family Cyprididae, is here described from a swamp in Maha Sarakham Province, Thailand. The new genus and species is mainly characterized by the 7-segmented antennula which has a Rome organ and remarkably long aesthetasc ya, the morphology of the sexually dimorphic antenna (A2), the markedly elongated A2 terminal segment, the short and thin α- and β-setae on the mandibular palp, the elongated terminal segment of the maxillula, the obviously 2-segmented male prehensile palp, the presence of d1 and d2 setae on the protopod of the second thoracopod (T2), the sexually dimorphic T2, the distinctive terminal segment of the third thoracopod bearing three long setae, the well-developed caudal ramus, the large hemipenis which has a complex internal structure, and the Zenker organ with funnel-shaped ends and numerous spiny whorls.
The number of currently described species of Afrotropical parasitoid wasps does not reflect the true species diversity. One of the most severely understudied parasitoid wasp groups is Ceraphronoidea. In this first study on Afrotropical mainland Ceraphronoidea in more than 20 years, which is also the first ever taxonomic monograph focusing on Ceraphronidae, we describe 88 new species of Ceraphronidae (85 new species) and Megaspilidae (3 new species) from Kakamega Forest (Kenya), Mt. Kilimanjaro (Tanzania) and Ivindo NP (Gabon): Aphanogmus abaluhya sp. nov., A. ashitakai sp. nov., A. idakho sp. nov., A. ikhongamurwi sp. nov., A. isiukhu sp. nov., A. kakamegaensis sp. nov., A. lateritorum sp. nov., A. mangimelii sp. nov., A. mariae sp. nov., A. mashariki sp. nov., A. nehbergi sp. nov., A. njia sp. nov., A. vestrii sp. nov., A. yala sp. nov. (all clavicornis species group), A. dimidiatus sp. nov., A. fraterculus sp. nov., A. guenteri sp. nov., A. kakakili sp. nov., A. kisiwa sp. nov., A. maua sp. nov., A. morriconei sp. nov., A. ndefu sp. nov., A. ngai sp. nov., A. nikii sp. nov., A. pilosicoxa sp. nov., A. rafikii sp. nov., A. robustus sp. nov., A. simbai sp. nov., A. taji sp. nov., A. ukanda sp. nov. (all fumipennis species group), A. campanula sp. nov., A. kikuyu sp. nov., A. pagoda sp. nov. (all tenuicornis species group), Ceraphron banda sp. nov., C. brashi sp. nov., C. breviharpis sp. nov., C. breviscapus sp. nov., C. buyangu sp. nov., C. chemositi sp. nov., C. cingulum sp. nov., C. clavatumeris sp. nov., C. digiti sp. nov., C. eaerendili sp. nov., C. ekero sp. nov., C. ellae sp. nov., C. eulbergi sp. nov., C. herreni sp. nov., C. hitagarciai sp. nov., C. insolitus sp. nov., C. isecheno sp. nov., C. isukha sp. nov., C. ivindoensis sp. nov., C. kaharabu sp. nov., C. kaimosiensis sp. nov., C. kakamegaensis sp. nov., C. kidole sp. nov., C. kimathii sp. nov., C. lirhanda sp. nov., C. longiharpis sp. nov., C. longisetae sp. nov., C. longumerunus sp. nov., C. maathaiae sp. nov., C. malava sp. nov., C. mamamutere sp. nov., C. metapleuralis sp. nov., C. mikoi sp. nov., C. mwekaensis sp. nov., C. nandi sp. nov., C. nzoia sp. nov., C. onesimusi sp. nov., C. pilosiharpis sp. nov., C. pleurosulcus sp. nov., C. reinholdi sp. nov., C. salazar sp. nov., C. sataoi sp. nov., C. semira sp. nov., C. sungura sp. nov., C. tenuimeris sp. nov., C. tiriki sp. nov., C. trietschae sp. nov., Cyoceraphron dhahabudorsalis sp. nov., C. harpe sp. nov., C. invisibilis sp. nov., C. kahawia sp. nov., C. njano sp. nov. (all Ceraphronidae), Conostigmus kijiko sp. nov., C. koleo sp. nov., and Dendrocerus wachagga sp. nov. (all Megaspilidae). In addition, we describe four species of Aphanogmus and five species of Ceraphron without formal naming. A neotype is designated for Dendrocerus anneckei Dessart, 1985 (Megaspilidae). With these new species we more than double the number described from the Afrotropical mainland (65 vs 153). The species numbers found allow us to estimate the real worldwide species number of Ceraphronoidea as being roughly 12 000–21 000, i.e., 16–29 times the number of the currently described species (~730, including the species described herein). This study is meant to highlight that it is necessary and also possible to study the parasitoid wasps of tropical regions and provide momentum for exploring the diversity of small and diverse insect groups in the Afrotropics and elsewhere while also providing the basic knowledge that is much needed for protecting biodiversity and understanding evolution and the networks of life on earth. All described species are diagnosed and illustrated, with focus on the male genitalia. Furthermore, we provide an identification key to males of Afrotropical Ceraphronidae.
Revision of the species confused with "Nereis falsa" de Quatrefages, 1866 (Annelida, Nereididae)
(2021)
Nereis falsa de Quatrefages, 1866 has been regarded as a cosmopolitan species, and several species described from different localities have been regarded as junior synonyms of N. falsa. The present study is an attempt to resolve the taxonomic confusion in N. falsa, which seems to contain several distinct species due to previous inappropriate synonymy, widely distributed in the Atlantic and eastern Pacific Oceans. For this purpose, the authors first propose the resurrection of the synonymy of N. falsa with Hediste diversicolor that was concluded during the 19th century but disregarded later. After the fixation of the identity of N. falsa sensu stricto, the authors re-evaluate the proper taxonomic status of species which have previously been confused with N. falsa. Type, topotype and non-type specimens were examined; most species are redescribed, and others are reinstated. Nereis splendida Grube, 1840 is a valid Mediterranean species, and a neotype is proposed; it includes the Mediterranean populations of what is currently regarded as N. falsa. Consequently, N. falsa is transferred to Hediste Malmgren, 1867, and some taxonomic comments are added for the latter genus and a key to species is also included. Nereis callaona Grube & Kröyer in Grube, 1857, N. marginata Grube & Örsted in Grube, 1857 and N. riisei Grube & Örsted in Grube, 1857 are restricted to tropical American shores and are all redescribed. Nereis pelagica lunulata Ehlers, 1901, formerly regarded as a junior synonym of N. falsa by Fauvel (1941), is redescribed and elevated in rank to species level. Nereis lucipeta Ehlers, 1908, formerly regarded as a junior synonym of N. splendida by Ehlers (1913) and of N. falsa by Fauvel (1919), is reinstated. Nereis occidentalis Hartman, 1945 is also redescribed. Furthermore, N. ambigua Treadwell, 1937, formerly regarded as a junior synonym of N. riisei by Monro (1933), deserves to be reinstated. Western Africa specimens recorded as N. falsa are newly described as N. mezianei sp. nov.
The family Hahniidae is reported from Thailand for the first time. The genus Hexamatia gen. nov. and two new species, Hexamatia seekhaow gen. et sp. nov. and Hahnia ngai sp. nov., are described and illustrated. DNA sequences are provided for all the species reported here. The phylogenetic position of the novel genus Hexamatia gen. nov. and its relation to Hahnia are discussed. Based on these results, a new combination is proposed for Hexamatia senaria (Zhang, Li & Zheng, 2011) gen. et comb. nov. = Hahnia senaria. Known distribution of the species Hahnia saccata Zhang, Li & Zheng, 2011, originally described from China, is expanded. A brief review and notes on the taxonomy of the six-eyed hahniids are included.
The genus Neostasina Rheims & Alayón is revisited. New material is examined, resulting in the description of seven new species: N. aceitillar sp. nov. (♀), N. bani sp. nov. (♂♀), N. demaco sp. nov. (♀) from Dominican Republic, N. juanita sp. nov. (♀), N. paraiso sp. nov. (♂♀), N. toronegro sp. nov. (♀) from Puerto Rico, and N. maisi sp. nov. (♂♀) from Cuba. New distribution records are given for N. amalie, N. cachote, N. guanaboa, N. iberia, N. saetosa, N. siempreverde and N. turquino. In addition, an updated identification key and updated distribution maps for all species of the genus are provided.
Rhytidaphora Reshchikov & Quicke gen. nov. (type species Rhytidaphora thailandica Reshchikov & Quicke gen. et sp. nov.) from Thailand is described and illustrated. It belongs to the tribe Euryproctini of the subfamily Ctenopelmatinae (Hymenoptera, Ichneumonidae) based on the absence of glymma and the subapical notch on the ovipositor. The new taxon differs from all other genera of Euryproctini by the occipital carina being broadly incomplete dorsally, the hypostomal carina joining the occipital carina shortly before the base of the mandible, distinctly pectinate tarsal claws, and immovably fused and strongly sculptured second and third metasomal tergites.
Drepanoistodus basiovalis (Sergeeva, 1963) is a common conodont species in Middle Ordovician strata of Baltica. For many years it has been widely accepted that the species encompasses a wide range of morphological plasticity. Hence, several different morphotypes that significantly deviate from the holotype have nonetheless been included in the broad species concept. In this study, we performed a detailed taxonomical study on 112 predominantly well-preserved specimens (geniculate elements) from the St. Petersburg region of Russia; 37 of these were selected for morphometric analyses together with 21 well-illustrated specimens from the published literature. The results demonstrate that, among the morphotypes that share some characteristics with D. basiovalis sensu lato, at least five species can be readily distinguished. Hence, three new species – Drepanoistodus iommii sp. nov., D. svendi sp. nov. and D. viirae sp. nov. – are here added to the previously known D. basiovalis and D. contractus (Lindström, 1955). In addition, some specimens were left under open nomenclature and assigned to Drepanoistodus aff. basiovalis and D. cf. suberectus (Branson & Mehl, 1933). In order to objectively compare the Drepanoistodus taxa and test the validity of the new species, we performed a Principal Component Analysis combined with non-parametric (PERMANOVA) tests based on 21 morphological characters.
Inocybe hopeae sp. nov. and first record of Pseudosperma keralense (Inocybaceae) from Thailand
(2023)
Based on genetic studies, supported further by morphological and ecological differences, we present a taxonomic novelty (Inocybe hopeae Raghoonundon & Raspé sp. nov.) and a new geographical record (Pseudosperma keralense) from forests of Northern Thailand. Inocybe hopeae is characterized by medium-sized basidiomes, brownish orange to brown pileus that is darker towards the margin, off-white to pale brown context, light brown to dark brown stipe with off-white basal mycelium and pale brown to grayish brown lamellae. A three-gene phylogeny (LSU, tef1, rpb2) coupled with macroscopic / microscopic descriptions and illustrations are provided confirming the species’ positions in their respective generic clades. Inocybe hopeae was sister to I. thailandica with strong support (BS = 100%, PP = 1.0). Our Thai collections of OR1629 had similar morphological characters and 100% identical sequences with the holotype of Pseudosperma keralense from India.
The Chinese members of the genera Leptothorax Mayr, 1855 and Temnothorax Mayr, 1861 are reviewed based on the morphological characters of the worker caste, and 66 species are recognized in China to date. A new synonym is proposed: T. opaciabdomin (Chang & He, 2001) is a junior synonym of T. mongolicus (Pisarski, 1969). Twenty-eight new species of Temnothorax, T. bailu sp. nov., T. chun sp. nov., T. chunfen sp. nov., T. chushu sp. nov., T. dahan sp. nov., T. dashu sp. nov., T. daxue sp. nov., T. dong sp. nov., T. dongzhi sp. nov., T. guyu sp. nov., T. hanlu sp. nov., T. jingzhe sp. nov., T. lichun sp. nov., T. lidong sp. nov., T. liqiu sp. nov., T. lixia sp. nov., T. mangzhong sp. nov., T. qingming sp. nov., T. qiu sp. nov., T. qiufen sp. nov.,T. shuangjiang sp. nov., T. xia sp. nov., T. xiaohan sp. nov., T. xiaoman sp. nov., T. xiaoshu sp. nov., T. xiaoxue sp. nov., T. xiazhi sp. nov., T. yushui sp. nov., are described from China based on worker caste. Three species of Temnothorax, T. desioi (Menozzi, 1939), T. susamyri (Dlussky, 1965) and T. volgensis (Ruzsky, 1905) are recorded in China for the first time. The following eight species are recorded in a province or autonomous region of China for the first time: Leptothorax acervorum (Fabricius, 1793) is a new record in Qinghai, Sichuan and Yunnan; Temnothorax angulohumerus Zhou et al., 2010 is a new record in Guizhou and Tibet; T. argentipes (Wheeler, 1928) is a new record in Sichuan and Yunnan; T. mongolicus (Pisarski, 1969) is a new record in Inner Mongolia; T. reticulatus (Chang & He, 2001) is a new record in Beijing, Gansu, Inner Mongolia, Jilin, Shaanxi and Yunnan; T. spinosior (Forel, 1901) is a new record in Yunnan; T. taivanensis (Wheeler, 1929) is a new record in Guizhou, Sichuan and Yunnan; and T. zhejiangensis Zhou et al., 2010 is a new record in Henan and Guangxi. A key based on the worker caste is provided for the 66 known Chinese species.
Late Miocene Conidae of Crete (Greece) have recently been evaluated for the genera Conilithes and Conus (Kalloconus). We continue this first inventory of the Miocene Conidae from Crete by discussing the genera Conus (Lautoconus), Conus (Stephanoconus), Conus (Plagioconus) and two species, not attributed to a subgenus of Conus. With the use of UV light, we recognized 17 species, of which five are new: Conus (Lautoconus) ictini sp. nov., Conus (Lautoconus) lauriatragei sp. nov., Conus (Lautoconus) damianakisi sp. nov., Conus (Stephanoconus) moissettei sp. nov. and Conus davolii sp. nov. Six species are first reported in the Late Miocene of Greece: Conus (Lautoconus) cf. baldichieri Borson, 1820, Conus (Stephanoconus) cf. taurinensis Bellardi & Michelotti, 1841, Conus fuscocingulatus Hörnes 1851, Conus (Plagioconus) elatus Michelotti, 1847 and Conus (Plagioconus) aquensis d’Orbigny, 1852. Six species are left in open nomenclature.
In this study, the new genus Spanglerelmis Polizei & Bispo is described; Microcylloepus ochus Hinton, 1940 is synonymized with Microcylloepus femoralis Hinton, 1940, and transferred to the new genus; and two new species, S. xiririca gen. et sp. nov. and S. timburi gen. et sp. nov. are described. The new genus can be characterized by the combination of the following characters: 1) pronotum without transverse, longitudinal or oblique impressions, sulci or gibbosities on disc; 2) elytra with a carina on interval III and two sublateral carinae on intervals V and VI; 3) mesoventrite with sides strongly raised; and 4) femora with an oblique belt of tomentum dorsally and a transverse belt ventrally. The specimens of the two new species were collected mainly in riffles of unimpacted streams in the Atlantic Forest in São Paulo State, Brazil. Scanning electron microscope images, an identification key for the genus and habitat notes are also presented.
A new fossil ceratopogonid genus and species from Lower Cretaceous Lebanese amber, Baskintoconops maaloufi Pielowska-Ceranowska gen. et sp. nov., is described and illustrated. The studied material originates from a newly discovered amber site in the Lebanese village Baskinta at a locality dubbed Qanat Bakish. The described genus is typified by its wing venation pattern combining characters of genera Fossileptoconops and Jordanoconops belonging to the subfamily Leptoconopinae.
Two new species of the genus Chlorogomphus are described based on both sexes collected from the Central Highlands of Vietnam. These species are C. hoaian sp. nov. (holotype male from Kon Ka Kinh National Park, 14.3672° N, 108.5368° E, alt. 1000 m) and C. vani sp. nov. (holotype male from Chu Yang Sin National Park, 12.4780° N, 108.4617° E, alt. 749 m). Furthermore, C. gracilis Wilson & Reels, 2001 is recorded from Vietnam for the first time, with notes on its morphology and detailed illustrations of male and female structures.
In this paper eight tribes (Gyrophaenini, Placusini, Homalotini, Diestotini, Falagriini, Athetini, Lomechusini, and Oxypodini), 19 genera and 42 species are recognized. Four genera (Brachyglyptaglossa n. gen. [Homalotini], Trisporusa n. gen., Daccordiusa n. gen. [Lomechusini], and Antistydatusa n. gen. [Oxypodini]) and 37 species are described as new. Each new genus and species is illustrated. Placusa fauveli Pasnik, 2001, from Sydney, is placed in synonymy with Placusa tridens Fauvel, 1878, from Sydney. A new combination to Spallioda for Calodera carissima Oliff is proposed.
Descriptions of two new elateroid beetles (Coleoptera: Eucnemidae, Elateridae) from Burmese amber
(2019)
Two new elateroid taxa are described from amber deposits excavated from the northern region of Myanmar. Two genera, Cenomana gen. nov. (Coleoptera: Eucnemidae), and Cretopityobius gen. nov. (Coleoptera: Elateridae) are described for the first time from Burmese amber. The following new species are described: Cenomana clavata sp. nov. and Cretopityobius pankowskiorum sp. nov. Each new species is diagnosed and illustrated.
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.
