Three new species of Onitis Fabricius, 1798 are described: Onitis bhomorensis sp. nov. from Assam (Northeast India), O. kethai sp. nov. and O. visthara sp. nov. from Karnataka (South India). Onitis bordati Cambefort, 1988 is recorded for the first time for the Indian subcontinent, from Meghalaya, India. Thus, the number of species of Onitis from the subcontinent has been raised to 20 and that of the Oriental region to 26. Illustrated identification keys to all the species of the genus Onitis from the Indian subcontinent are provided with distributional details and maps. Lectotype and paralectotypes designated for Onitis philemon Fabricius, 1801. Descriptions are provided for aedeagus of seventeen species of Onitis, as well as images of type specimens for nine species from their respective repositories. Distribution maps are provided for the species of Onitis of the Indian subcontinent.
Crickets (Order Orthoptera, Infraorder Gryllidea) are under-represented in New Zealand, with a total of eight species identified and formally described thus far. These include three endemic species in the family Trigonidiidae: the trig Trigonidium (Metioche) maoricum (Walker, 1869) and the ground crickets Bobilla nigrova (Swan, 1972) and B. bigelowi (Swan, 1972). Scaly crickets (family Mogoplistidae) are naturally absent in New Zealand, but one species, Ornebius aperta Otte & Alexander, 1983, has established after introduction from Australia in the 1970s. In this work, I re-examine the small crickets (families Trigonidiidae and Mogoplistidae) from New Zealand based on 368 specimens collected throughout the country, their morphology, and their song. In the subfamily Nemobiinae, I provide new diagnostic characters to discriminate between the two native species in the genus Bobilla Otte & Alexander, 1983. Additionally, I identify two species in the genus Pteronemobius Jacobson, 1904; these are P. truncatus (Saussure, 1877) and P. cf. arima Otte & Alexander, 1983, both of which are believed to be recent arrivals from Australia. The latter had been thus far undetected in New Zealand. Finally, I describe two new species of mute Nemobiinae belonging to new monotypic genera, Austronemobius chelatus gen. et sp. nov. and Mutonemobius marmoratus gen. et sp. nov. In the subfamily Trigonidiinae, the species Trigonidium (Metioche) maoricum is moved back to the subgenus Trigonidium (Trigonidium) Rambur, 1838 based on morphology. Amended descriptions are provided for this genus and species. The Australian species Trigonidomorpha sjostedti Chopard, 1925 is synonymised with Trigonidium australianum (Chopard, 1925), and the genus Trigonidomorpha Chopard, 1925 is synonymised with Trigonidium Rambur, 1838. In the family Mogoplistidae, I show that Ornebius aperta has established in the Auckland, Waikato, Taranaki and Coromandel regions. Based on song and morphology of the male terminalia, populations in Northland may belong to a separate species, referred to in this work as Ornebius aff. aperta Otte & Alexander, 1983.
A documented checklist of the Crustacea (Stomatopoda, Decapoda) is provided for the southern Guianas region (sGuianas), a homogeneous ecoregion including Guyana, Suriname, French Guiana and the Brazilian State of Amapá. The history of crustacean collections undertaken there between 1759 and 2022 is summarized. In total, 529 species are listed. Biodiversity varies between countries: 165 species in Guyana; 317 in Suriname, 343 in French Guiana, and 315 in Brazil Amapá, as a direct result of different sampling efforts. There are 22 Stomatopoda and 507 Decapoda, ranked by numerical diversity as Brachyura (206), Caridea (113), Anomura (85), Dendrobranchiata (67) and others (36). The list is analyzed with the species classified by major biotopes, distinguishing those from freshwater, mangroves and estuaries, and frankly marine environments. Regional comparisons are made in the Western Atlantic showing that the sGuianas marine fauna is depauperate compared to that of other regions. This is explained by the influence of the Amazon River plume, carrying desalinated water and fine sediments, which leads to the reduction of coral reef formations in sGuianas. Only a few species of freshwater crabs (genera Kunziana and Microthelphusa) are endemic to the region. The pace of species discovery over the years indicates that the sGuianas fauna remains still imperfectly known and that probably more than 600 species are present in the region.
New taxa and new records of Winnertziinae and Porricondylinae (Diptera: Cecidomyiidae) from Germany
(2024)
Winnertziinae and Porricondylinae are two subfamilies of mycophagous Cecidomyiidae (gall midges). An earlier census in 2021 found the German fauna of both groups to comprise 53 species and 28 genera – only a small proportion of the nearly 400 species and 75 genera known from all of Europe. A 24-month inventory in 2021‒2023, whose most significant taxonomic and faunistic outcomes are presented here, yielded evidence of an additional 142 species and 24 genera present in Germany, more precisely 41 species and three genera of Winnertziinae, and 101 species and 21 genera of Porricondylinae. Included in these numbers are 30 new species (six Winnertziinae, 24 Porricondylinae) and one new genus (of Porricondylinae) described and named here. The number of potentially new species discovered during the project is considerably larger (85+), but the too poor condition of the specimens and various other circumstances do not permit their taxonomic description at this stage. New taxa named in the present paper are Johnsonomyia szadziewskii sp. nov., Rhipidoxylomyia bilobata sp. nov., Winnertzia haushoferorum sp. nov., Winnertzia incrassata sp. nov., Winnertzia macrodens sp. nov., Winnertzia subdentata sp. nov., all Winnertziinae, Asynapta doczkali sp. nov., Asynapta falcata sp. nov., Bryocrypta longissima sp. nov., Camptomyia serrata sp. nov., Cassidoides rainensis sp. nov., Cassidoides riparius sp. nov., Claspettomyia gracilostylus sp. nov., Claspettomyia parvidentata sp. nov., Divellepidosis bavarica sp. nov., Lamellepidosis luderbuschensis sp. nov., Neurepidosis hartschimmelhofensis sp. nov., Neurepidosis simplex sp. nov., Parepidosis lobata sp. nov., Porricondyla acutistylata sp. nov., Porricondyla insolita sp. nov., Porricondyla oblonga sp. nov., Porricondyla ornata sp. nov., Porricondyla pilosoides sp. nov., Porricondyla plana sp. nov., Porricondyla pumila sp. nov., Schistoneurus paraimpressus sp. nov., Schistoneurus subimpressus sp. nov., Spungisomyia germanica sp. nov., Wohllebenia gen. nov., and Wohllebenia hybrida gen. et sp. nov., all Porricondylinae. Taxonomic descriptions are based on both the morphology of males and, if available, CO1 (DNA barcode) sequences, using specimens collected by Malaise traps in Bavaria and Baden-Württemberg, the two southernmost federal states of Germany. Released here are 150 BINs new to BOLD as well as 145 species names for previously unidentified BINs in BOLD. Redescriptions of male morphology are provided for Camptomyia heterobia Mamaev, 1961, Claspettomyia carpatica Mamaev, 1998, Dicerura scirpicola Kieffer, 1898, and Winnertzia betulicola Mamaev, 1963. The state of knowledge of Germany’s fauna of mycophagous gall midges is discussed.
The spider fauna of most African regions is severely understudied, there is a need for revision of old data and publishing new records. The previous list of jumping spiders (Salticidae) of Uganda contained merely 25 species. The presented survey, which is based on material from several museum collections, provides new faunistic and taxonomic information. The data already available in the literature are critically reviewed and an updated checklist of jumping spiders from Uganda is published. Two new genera are established: Phintellosa gen. nov. with type species Maevia comosissima Simon, 1886 and Ruwenzorek gen. nov. with type species Ruwenzorek evansi gen. et sp. nov. Thirty-three species are newly described: Asemonea wagneri sp. nov. (♂), Dendryphantes ruwenzori sp. nov. (♂♀), Dendryphantes sasa sp. nov. (♀), Enoplomischus pulcher sp. nov. (♂♀), Evarcha degeni sp. nov. (♂), Finger minor sp. nov. (♂♀), Hermosa yurai sp. nov. (♂♀), Hermotimus cornutus sp. nov. (♂♀), Hyllus formosus sp. nov. (♀), Icius entebbensis sp. nov. (♂), Icius hortensis sp. nov. (♂), Longarenus mpanga sp. nov. (♀), Massagris budongo sp. nov. (♂♀), Mexcala inopinata sp. nov. (♂♀), Myrmarachne corusca sp. nov. (♀), Phintella bella sp. nov. (♂♀), Phintella jucunda sp. nov. (♀), Phintella nilotica sp. nov. (♂), Plexippoides dentatus sp. nov. (♂), Rhene amabilis sp. nov. (♂♀), Rhene eximia sp. nov. (♂♀), Rhene hexagon sp. nov. (♂♀), Rhene sororis sp. nov. (♀), Rhene ugandensis sp. nov. (♀), Ruwenzorek evansi gen. et sp. nov. (♀), Thiratoscirtus africanus sp. nov. (♂♀), Thiratoscirtus bwindi sp. nov. (♀), Thiratoscirtus magnus sp. nov. (♀), Thiratoscirtus spinifer sp. nov. (♂), Thyene masindi sp. nov. (♂♀), Thyene perfecta sp. nov. (♂), Tusitala ugandensis sp. nov. (♀) and Vicirionessa ignota sp. nov. (♀). Five specific names are synonymized: Enoplomischus spinosus Wesołowska, 2005 with Enoplomischus ghesquierei Giltay, 1931, Evarcha elegans Wesołowska & Russell-Smith, 2000 [removed from synonymy of Evarcha werneri (Simon, 1906)] with Hyllus dotatus (Peckham & Peckham, 1903), Myrmarachne mussungue Wanless, 1978 with Myrmarachne evidens Roewer, 1965, Plexippus fibulatus Dawidowicz & Wesołowska, 2016 with Schenkelia modesta Lessert, 1927 and Vicirionessa prenanti (Berland & Millot, 1941) with Vicirionessa fuscimana (Simon, 1903). Two new combinations are proposed: Phintella chopardi (Berland & Millot, 1941) comb. nov. ex Cosmophasis and Phintellosa comosissima (Simon, 1886) gen. et comb. nov. ex Maevia. The as yet unknown females of nine species are described for the first time: Alfenus calamistratus Simon, 1902, Baryphas scintillans Berland & Millot, 1941, Dendryphantes elgonensis Wesołowska & Dawidowicz, 2014, Depreissia myrmex Lessert, 1942, Mikrus ugandensis Wesołowska, 2001, Phintella brevis Wesołowska & Russell-Smith, 2022, Phintellosa comosissima (Simon, 1886), Thiratoscirtus patagonicus Simon, 1886 and Thyene verdieri (Berland & Millot, 1941). The resulting list of salticids from Uganda now contains 141 species, of which 116 are recorded in this country for the first time. There is little overlap in the species list of Uganda and that of the neighbouring countries, not exceeding 40%.
Twelve species of Platypalpus Macquart are described as new to science from different regions in Morocco: P. atlasensis sp. nov., P. brevicornoides sp. nov., P. ebejeri sp. nov., P. fatnae sp. nov., P. pauli sp. nov., P. imlilensis sp. nov., P. miroslavi sp. nov., P. moroccensis sp. nov., P. nigritellus sp. nov., P. rifensis sp. nov., P. shamshevi sp. nov. and P. taninensis sp. nov. Platypalpus albocapillatus Fallén, 1815 and P. boreoalpinus Frey, 1943 are recorded here for the first time from the whole of North Africa, with the first report of P. verbekei Grootaert & Chvála, 1992 from Morocco. Some species newly recorded from new biogeographical areas within the country are also reported here. Descriptions and illustrations of new species are provided, as well as distributions of all species recorded from Morocco.
Species of the cleptoparasitic bee genus Triepeolus Robertson, 1901 (Hymenoptera: Apidae: Nomadinae) of which the female has a trapezoidal or triangular pseudopygidial area with bright, reflective setae and a concave apical margin are revised. This entirely New World group includes the widely known species T. simplex Robertson, 1903 and is thus termed the simplex species group. A total of 18 species in the T. simplex group are recognized as valid, of which seven are newly named and described—T. apache sp. nov., T. eumeniformis sp. nov., T. hirsutus sp. nov., T. oblongimacula sp. nov., T. parahirsutus sp. nov., T. paucipunctatus sp. nov., and T. shoshone sp. nov., all from North America. Eleven redundant names are newly synonymized under three valid ones as follows: Epeolus rugulosus Cockerell, 1917 syn. nov., E. metatarsalis Friese, 1921 syn. nov., and T. bilunatus Cockerell, 1949 syn. nov. under Triepeolus mexicanus (Cresson, 1878); E. lectiformis Cockerell, 1925 syn. nov., T. lusor Cockerell, 1925 syn. nov., and T. junctus Mitchell, 1962 syn. nov. under T. rhododontus Cockerell, 1921; and E. permixtus Cockerell, 1923 syn. nov., T. brunnescens Cockerell & Sandhouse, 1924 syn. nov., T. pacis Cockerell, 1925 syn. nov., E. sarothrinus Cockerell, 1929 syn. nov., and E. sarothrinus var. confluens Cockerell, 1929 syn. nov. under T. segregatus (Cockerell, 1900). Species limits were established using an integrative systematics approach, namely considering morphological and biogeographic evidence as well as DNA barcode data. Taxon concepts are revised for all species in the T. simplex group, with morphological diagnoses and keys presented to enable their identification. Known information on the ranges and ecology of the treated species is summarized.
Isostichopus badionotus (Selenka, 1867) is distributed in the Atlantic Ocean. It has been recognized as a species with highly variable intraspecific coloration. To clarify taxonomic confusion and show the characters for correct identification of this valuable species, mitochondrial DNA (16S and COI), color patterns, external and internal morphology, ossicles, and habitat were examined in specimens from museum collections and from original sampling. As part of the revision, I. fuscus (Ludwig, 1875) from the Eastern Pacific Ocean and I. macroparentheses (Clark, 1922) from the Caribbean Sea, the only other two species currently recognized in the genus Isostichopus, were included. It was concluded that I. fuscus and I. macroparentheses are distinct and valid species, and that I. badionotus consists of two species: I. badionotus and I. maculatus (Greeff, 1882), previously synonymized as I. baqdionotus by Clark (1922). Isostichopus maculatus includes two subspecies, the nominal I. maculatus maculatus (Greeff, 1882) and I. maculatus phoenius (Clark, 1922), described as Stichopus badionotus var. phoenius Clark, 1922. Isostichopus maculatus maculatus, distributed in the East Atlantic, is very similar to I. maculatus phoenius, but differs in DNA characters, color pattern, and the size and shape of the tables in the dorsal papillae. Isostichopus maculatus phoenius, widely distributed in the Caribbean Sea and the Gulf of Mexico, is sympatric with I. badionotus, has similar ossicles but is clearly distinguished by its DNA sequences, color patterns, and habitat preferences. For the first time, ossicles from internal organs are described for Isostichopus, enhancing original species descriptions. Distribution maps, habitat, biology, conservation status, and a taxonomic key for distinguishing these species to aid their fishery management and aquaculture are presented.
India is a large country in Asia, and covers the transition zone between the Palaearctic and Indomalayan biogeographic realms, with influences from both. Present in India are members of the genus Andrena, an enormous bee genus distributed predominantly throughout the Holarctic, with the greatest Indian diversity in the Himalayan region due to its Palaearctic influences. Despite early studies in the late 19th and early 20th centuries, there has been almost no work on this group in India during the past century. A revision of type and non-type museum material combined with new collections has produced a revised total of 36 species of Andrena for India, including 11 species reported for the first time as well as the newly described Andrena (Melandrena) kedarnatha Wood & Gautam sp. nov. (northern India and Nepal) and Andrena (Simandrena) tungnatha Wood & Gautam sp. nov. (northern India). The true holotype of A. (Euandrena) communis Smith, 1879 is definitively located. Andrena burkelii Bingham, 1908 is synonymised with A. (Pallandrena) morosa Cameron, 1897. Lectotypes are designated for A. (Euandrena) murreensis Cockerell, 1923 and A. (incertae sedis) comberima beharica Cockerell, 1920. Further comments are made on the status of Andrena taxa described from India for which type material is and is not currently available. Thirty additional Andrena taxa suggested as present in the Indian fauna are excluded as either erroneous or lacking supporting data. These results illustrate the extent to which study of the Indian Andrena fauna has been confused, and provide a more stable taxonomic base for future studies in this country.
Two previously unrecognized species attributable to the genus Kontrimavichusia Makarikov & Binkienė, 2022 in arvicoline rodents from the North Caucasus are described. Kontrimavichusia testiculata sp. nov. is described from Microtus majori (Thomas, 1906) from the northwestern Caucasus (Republic of Adygeya and Karachay-Cherkess Republic, Russia) and Kontrimavichusia hobergi sp. nov. is described from Microtus daghestanicus (Shidlovsky, 1919) from the central Caucasus (Republic of North Ossetia, Russia). Kontrimavichusia testiculata is readily distinguishable from K. asymmetrica (Janicki, 1904) and K. hobergi in having a larger number of testes (4–6 per proglottis), larger suckers and a longer cirrus and cirrus-sac. In addition, the new species differs from its congeners by the position of the cirrus-sac with regard to the poral osmoregulatory canals and position of distal end of the rostellar pouch relative to the posterior margins of the suckers. Kontrimavichusia hobergi can be readily distinguished from its congeners by the arrangement of the testes in a triangle and the position of the cirrus-sac with regard to the poral osmoregulatory canals. In addition, this previously unrecognized species differs from K. asymmetrica and K. testiculata by the smaller dimensions of the fully developed strobila and a narrower ovary. The cirrus-sac of K. hobergi is larger than that in K. asymmetrica but smaller than that in K. testiculata. We also used partial sequences of the nuclear ribosomal 28S rRNA gene and mitochondrial nad1 gen to justify the generic arrangement and independent status of these two new species which are characterized in the current manuscript.
