A global synonymical checklist of the species and higher taxa of the insect order Megaloptera is provided. The checklist includes both extant and extinct taxa, and recognizes 2 families, 4 subfamilies, 48 genera, 425 species, and 6 subspecies. Both families (Corydalidae and Sialidae), and three of the four subfamilies (Corydalinae, Chauliodinae, and Sialinae) are known from both extant and extinct species; the Sharasialinae (Sialidae) is entirely extinct. Country-level geographic distribution data are provided for all species and subspecies. Synoptic type data are provided for taxa in the family and genus groups. Summary data are given for the numbers of megalopteran species currently known to occur in each of the major biogeographical regions of the world, and for the world fauna. Increase of knowledge about the diversity of the world Megaloptera fauna is summarized in counts of valid species described per decade and in a global taxonomic description curve. An updated set of keys to the world families, subfamilies, and genera of the Megaloptera is also provided.
Zwei Brombeerarten der Sektion Rubus ser. Glandulosi (Wimmer & Grabowski) Fokke werden neu beschrieben. Beide sind in Thüringen und Nordbayern verbreitet: Rubus exarmatus H. E. Weber & W. Jansen spec. nov. und Rubus perlongus H.E. Weber & W. Jansen spec. nov. Die Arten sind durch Fotos ihrer Holotypen abgebildet, ihre bekannte Verbreitung ist durch Rasterkarten dargestellt.
Es wird die Verschiedenheit der einzelnen Larvenstadien hervorgehoben, die in der Hypermetamorphose ihren Gipfel erreicht. Am Beispiel der Coleoptera wird der Stand der taxonomischen Kenntnisse erörtert und in seiner z.T. krassen Differenzierung erläutert. Es werden Möglichkeiten der Determination von Larven vorgestellt. Einige Ordnungen der Holometabola können auch durch apomorphe Merkmale der Larven als Monophyla wahrscheinlich gemacht werden, z. B. Neuroptera, Trichoptera und Siphonaptera, bei anderen gestatten dies die gegenwärtigen Kenntnisse nicht, z. B. Coleoptera und Hymenoptera. Auch die Monophylie subordinierter Taxa kann anhand von abgeleiteten Merkmalen der Larven dargestellt werden, wie am Beispiel der Familie Scirtidae (Coleoptera) erläutert wird. Es wird darauf hingewiesen, dass Inkongruenzen von Larval- und Imaginalsystemen wertvolle Hinweise auf Forschungsbedarf zur Auflösung paraphyletischer Gruppen liefern können. Die Bedeutung der Larven für die Taxonomie, Systematik und Phylogenetik ist sehr groß, und es wird eine verstärkte Aufmerksamkeit zur Erforschung der „Holomorphe“ im Sinne Hennigs angemahnt.
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.
The present study aims to resolve the taxonomic confusion involving several taxa within Mycetophagidae Leach, 1815, originating from the introduction of the genus Atritomus Reitter, 1877, and then by its subsequent controversial interpretation. A detailed overview of the taxonomic and nomenclatural history of the taxa previously linked to Atritomus is provided. The authors propose the introduction of Stereophilus Biscaccianti, Audisio & Esser gen. nov. for Atritomus filicornis Reitter, 1887, and the restoration of Entoxylon Ancey, 1869 at the genus rank, together with some rectifications regarding the authorship and the date of publication of both Entoxylon and its type species, E. abeillei Ancey, 1869. Moreover, the Ethiopian species Atritomus vicinus Grouvelle, 1908 is herein transferred to the genus Typhaeola Ganglbauer, 1899 based on the examination of the holotype. The following new combinations are proposed: Entoxylon baudii (Seidlitz, 1889) comb. nov. (from Esarcus Reiche, 1864), Entoxylon besucheti (Dajoz, 1964) comb. nov. (from Esarcus subg. Entoxylon), Entoxylon franzi (Dajoz, 1964) comb. nov. (from Esarcus subg. Entoxylon), Entoxylon inexpectatus (Dajoz, 1964) comb. nov. (from Esarcus subg. Entoxylon), Entoxylon martini (Reitter, 1887) comb. nov. (from Esarcus), Stereophilus filicornis (Reitter, 1887) gen. et comb. nov. (from Atritomus), Typhaeola vicina (Grouvelle, 1908) comb. nov. (from Atritomus).
We here describe a new Indian helicarionoidean genus, Varadia Bhosale & Raheem gen. nov., containing the single species Varadia amboliensis Bhosale, Thackeray, Muley & Raheem gen. et sp. nov. This new semi-slug is endemic to the northern and central Western Ghats and is primarily a forest-living species. We describe and figure the shell, reproductive system, radula, spermatophore and external morphology of this new species, and detail its known distribution. We explore its relationships to other helicarionoideans using phylogenetic analyses of DNA sequence data for part of the ribosomal RNA gene cluster and discuss the morphology of the new genus in relation to other, primarily South Indian, helicarionoidean taxa. Based on characters of the reproductive system, particularly the male genitalia and the gametolytic sac, we provisionally place Varadia gen. nov. in the Macrochlamydinae (Ariophantidae). This is consistent with the results of our molecular phylogenetic analyses. The combination of large size, broad, densely tuberculated shell lobes and a shell with ca 4 whorls and a disproportionately large body whorl makes V. amboliensis gen. et sp. nov. unique among the helicarionoidean taxa of the Western Ghats. The new semi-slug is also highly distinctive in the morphology of its male genitalia.
A re-analysis of the morphological phylogeny of the Nopinae is made, based on an update in the description of Aamunops Galán-Sánchez & Álvarez-Padilla, 2022 and the addition of the recently described genera Nopsma Sánchez-Ruiz, Brescovit & Bonaldo, 2020 and Roddemberryus Sánchez-Ruiz & Bonaldo, 2023. Two new species, Aamunops hoof sp. nov. (male) and Aamunops yiselae sp. nov. (male and female), are also described, which allows a better understanding of the genus morphology and resulted in an emended diagnosis. The description of Aamunops has been updated to include several characteristics of the ultrastructural morphology, legs, chelicerae, palps and female genitalia. The inclusion of these new characters of Aamunops along with those of Nopsma and Roddemberryus in the previous data matrix resulted in a new, completely different hypothesis of the relationships of the nopine genera: Nopsma is part of a group formed by Cubanops and Nyetnops, while Aamunops and Roddemberryus are grouped with representatives of Tarsonops. The four-eyed Nopsides ceralbonus Chamberlin, 1924 was recovered as the most basal species of Nopinae. The relationships among genera of Nopinae and the phylogenetic position of three species, whose taxonomic position is doubtful (Cubanops luquillo Sánchez-Ruiz, Brescovit & Alayón, 2015, Orthonops confuso Galán-Sánchez & Álvarez-Padilla, 2022 and Tarsonops irataylori Bond & Taylor, 2013), is also discussed.
The taxonomic status of the widely distributed freshwater crab Potamonautes lirrangensis (Rathbun, 1904) sensu lato is revised because morphological and molecular evidence indicates that this taxon is a complex comprising more than one species. Four taxa are now recognized: Potamonautes lirrangensis (Rathbun, 1904) s. str. and P. kisangani sp. nov. from the Middle Congo River in Central Africa, P. amosae sp. nov. from the drainages of Lakes Kivu and Tanganyika, and P. orbitospinus (Cunnington, 1907) from Lake Malawi which had been previously synonymised with P. lirrangensis s. lat. Diagnoses, illustrations and distribution maps are provided for each of these taxa and they are compared to similar species from Central and Southern Africa.
Two novel species of Russula (Russulaceae, Russulales), R. coronaspora Y.Song sp. nov. and R. minor Y.Song sp. nov. belonging to subgenus Russula crown clade, are described based on both morphological and phylogenetic evidence. In morphology, R. coronaspora sp. nov. is mainly characterized by its distinct spores ornamented with sparse, cylindrical and isolated spines, which resemble coronavirus, and gelatinized pileipellis with pileocystidia mostly septate and sometimes branched; R. minor sp. nov. possesses a very small basidiocarp with pileus less than 2.5 cm in diameter., small basidia, easily peeling and gelatinized pileipellis with slender terminal cells and abundant SV+ pileocystidia. Positions of the two new species in both phylogenetic trees based on ITS and 5-locus sequences (nLSU, mtSSU, rpb1, rpb2 and tef1) confirm their distinct taxonomic status.
Two species of Xorides Latreille, 1809 are reported parasitizing wood-boring insects in trunks and relatively larger twigs of Juglans mandshurica Maxim. in Kuandian Manzu Autonomous County, Liaoning, in the Palaearctic part of China. Two new species are described: X. juglanse Sheng, Broad & Sun sp. nov. and X. kuandianense Sheng, Broad & Sun sp. nov. One species, X. sapporensis (Uchida, 1928), was associated with wood-borers in J. mandshurica Maxim. for the first time. A key to the 46 species of Xorides Latreille known from China is provided.
Two new species of the genus Eponisiella Emeljanov, 1984 are described and illustrated from China (Guizhou and Shandong Provinces). These are E. dafangensis sp. nov. and E. shandongensis sp. nov., giving the genus eight species in total. A key to the species of Eponisiella is provided as well as a map of their geographic distribution, which is briefly discussed.
Two new opilionid species from suborder Cyphophthalmi, family Sironidae, Siro franzi Karaman & Raspotnig sp. nov. and Siro ozimeci Karaman sp. nov., from Austria and Croatia respectively, are described and illustrated. Both species show a close relation to two other relict sironid species from the southern and eastern parts of the Alps, Siro valleorum and Siro crassus. All four species are treated here as a monophyletic, alpine group of genus Siro, opposed to the remaining two European sironids, S. rubens and S. carpaticus (palaeoeuropean Siro group). The history of the alpine Siro group parallels the history of a part of the dynamic European archipelago in the Mediterranean Tethys area, which became a part of the Alpine orogeny. Diversification of the alpine Siro group is the result of the orogenic evolution of the Alps, linked to the Austroalpine and South Alpine tectonic units.
Two new species, Camponotus sholensis sp. nov. and Camponotus meghalayaensis sp. nov. are described from India and redescriptions of four species (C. habereri Forel, 1911, C. keihitoi Forel, 1913, C. quadrinotatus Forel, 1886 and C. simoni Emery, 1893) new to India are provided. We also recorded and described an unidentified form ‘Camponotus sp. 101’ that does not correspond to any species already known in India. An identification key supplemented with digital images of the known species of the genus is also provided.
Two new species of Strandesia Stuhlmann, 1888 are described from the northeastern part of Thailand: S. karanovicae sp. nov. and S. amnatcharoenensis sp. nov. Strandesia karanovicae is characterized by a tumid carapace in dorsal view, a small anterior overlap, the absence of a dorso-subapical seta on the first segment of the antennule (A1), a large aesthetasc Y on the antenna, an α seta shape with a needle-like tip and a large β seta on the mandibular palp (Md-palp), serrated bristles on the maxilla, a long h1 seta on the second thoracopod (T2) and a slender caudal ramus (CR). Strandesia amnatcharoenensis has a small compressed posterior part of the right valves (RV) which makes it closely related to S. pholpunthini Savatenalinton, 2015. The new species can be distinguished primarily by a considerably small anterior overlap of the left valve over the right valve (RV), a postero-ventral flange of the RV, a remarkably large claw Ga of the CR and the chaetotaxy of the limbs, especially A1, Md-palp and T2. In addition, in the present study, the sexual population of S. martensi Savatenalinton, 2015 is recorded for the first time, and thus the first description of the male is provided here. Moreover, the morphological examination of both males and females revealed differences between asexual and sexual females and also points to the fact that S. martensi is a mixed reproduction species. This is the first record of the mixed reproductive mode in the genus Strandesia or even in the Cypricercinae.
Two new species of Onciderini Thomson, 1860 (Coleoptera: Cerambycidae: Lamiinae) are described and illustrated: Neocherentes adrianoi Nearns and Monné, from Brazil, and Neocherentes pergeri Nearns and Monné, from Bolivia. The male of Neocherentes dilloniorum Tippmann, 1960 is redescribed and the female is described for the first time. Neocherentes dilloniorum is excluded from the Brazilian fauna. A key to the known species of Neocherentes Tippmann, 1960 is provided.
Two new species of Sonerila Roxb. (Melastomataceae), S. erectifolia Phonep., Soulad. & Tagane sp. nov. from southern Laos, and S. souvannii Phonep. & Soulad. sp. nov. from central Laos, are described and illustrated. Comparisons with morphologically similar species are presented, along with ecological information and preliminary conservation status. A key to the species of Sonerila in Laos is also provided.
Two new species, Russula pseudopunicea C.L.Hou, G.Q.Cheng & H.Zhou sp. nov. and R. wulingshanensis C.L.Hou, G.Q.Cheng & H.Zhou sp. nov., from Yanshan mountains in North China are described herein based on morphological and phylogenetic analyses of nrITS, and nrLSU-rpb2-mtSSU gene regions. Morphologically, R. pseudopunicea sp. nov. is characterised by a reddish brown, light brown to brownish orange pileus with a greyish yellow margin, subglobose to broadly ellipsoid basidiospores with warts forming a partial reticulum and pleurocystidia turning grey to purplish red in sulfovanillin. Russula wulingshanensis sp. nov. is characterised by a purple pinkish pileus with a grey-white to grey-purple margin, subglobose to broadly ellipsoid basidiospores with isolated warts, and pileocystidia turning black in sulfovanillin. Phylogenetic and morphological analyses resolved the two species in Russula subg. Heterophyllidia. Russula pseudopunicea sp. nov. and R. wulingshanensis sp. nov. were placed in the lineages of subsect. Virescentinae and subsect. Griseinae, respectively.
