Bujurquina is the most widely distributed and species-rich genus of cichlids in the western Amazon of South America. In this study we describe a new species from Peru from a hypothesized reverse flowing river system. Prior to the origin of the modern Amazon River at 4.5 Ma, this river system had its headwaters on the Iquitos arch, one of several main structural arches (swells) in the Amazon. Prior to the origin of the modern Amazon these arches formed topographic barriers of drainage basins in lowland Amazonia. For our analyses we use morphological and molecular data, analyzed through multivariate statistics and molecular phylogenies, respectivelly. For all valid species in the genus (except B. cordemadi and B. pardus) we additionally for the first time provide photographs of live specimens. Based on DNA phylogeny and coloration patterns we demonstrate that Bujurquina is divided into two main clades and based on this we provide a dichotomous key for all the species.
A new species of Bathynellidae is described from Colorado (USA). Hobbsinella gunnisonensis Camacho & Taylor sp. nov. displays a unique combination of morphological characters including seven-segmented antenna lacking medial seta on exopod, antennule slightly longer than antenna, three-segmented mandibular palp, four articles on endopod of thoracopods I to VII and five spines on sympod and three spines on endopod of the uropods. Partial sequences of cytochrome oxidase I (COI) and 18S have been obtained from several specimens of the new species. The mitocondrial and nuclear DNA data complement the traditional morphological taxonomic description support the validity of the new species. Molecular data for the Bathynellidae demonstrate the presence of two highly divergent genetic units, with the new species placed in the genus Hobbsinella. With the description of Hobbsinella gunnisonensis Camacho & Taylor sp. nov. and its molecular characterization, we discovered an interesting distribution of the genus, which occurs in both sides of the Continental Divide (Texas and Colorado) and different habitats.
Se revisan las especies del género Eurybia Illiger (Lepidoptera: Riodinidae) de Colombia en base al estudio de especimenes depositados en colecciones nacionales publicas y privadas.

Here, I describe four new species of the Neoserica vulpes species group: Neoserica daxue sp. nov., N. mianningana sp. nov., N. myanmarensis sp. nov., and N. yanyuan sp. nov. Genitalia and habitus of the new species are illustrated. Additional records of species from the group are given and the key to species of the Neoserica vulpes species group is updated.
Paramacrobiotus bengalensis sp. nov. was discovered in a moss sample collected from a tree in West Bengal, India. We describe this new species using detailed morphological and morphometric data obtained from phase contrast microscopy and scanning electron microscopy, along with molecular and phylogenetic data analyses. Due to the presence of a cap-like structure at the distal portion of egg processes, the new species showed the highest similarity with Paramacrobiotus garynahi (Kaczmarek, Michalczyk & Diduszko, 2005), Paramacrobiotus alekseevi (Tumanov, 2005), Paramacrobiotus filipi Dudziak, Stec & Michalczyk, 2020, Paramacrobiotus sagani Daza, Caicedo, Lisi & Quiroga, 2017, Paramacrobiotus vanescens (Pilato, Binda & Catanzaro, 1991) and Paramacrobiotus gadabouti Kayastha, Stec, Mioduchowska & Kaczmarek, 2023. However, it can be differentiated from them by some morphological and morphometric characteristics. The genetic data corroborated our phenotypic outcome further supporting the new species hypothesis.
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.
The nitidus species group of the bee genus Scrapter Lepeletier & Serville, 1828 is redefi ned, revised and 15 species are described as new for science: S.caeruleus sp. nov. ♀, S.confusus sp. nov. ♀♂, S.convexoides sp. nov. ♂, S. convexus sp. nov. ♀♂, S. crassipunctatus sp. nov. ♀♂, S.felicis sp. nov. ♀♂, S.fl avipunctatus sp. nov. ♀♂, S.imparilis sp. nov. ♀♂, S. littoralis sp. nov. ♀, S.longicornis sp. nov. ♂, S.montanus sp. nov. ♀♂, S.mpumalangensis sp. nov. ♀♂, S.obtusus sp. nov. ♀♂, S. perpunctatulus sp. nov. ♂ and S.variabilis sp. nov. ♀♂. The previously unknown males of S. divergens (Friese, 1925), S. semirufus Cockerell, 1932 and S. perpunctatus Cockerell, 1933 are described for the fi rst time. All currently known 28 species of the S. nitidus species group are redescribed, imaged and included in a key to facilitate their identifi cation.
The Australian genus Pleuroseta Richards, 1973 is revised, including P. wentworthi (Richards, 1973) and three new species: P. ingens sp. nov. (Queensland), P. monteithi sp. nov. (Queensland) and P. occidentalis sp. nov. (Western Australia). Leptocera (Biroina) dorrigonis Richards, 1973 is treated as a new junior synonym of Pleuroseta wentworthi.
A new species Alainites neeru sp. nov. is described based on larvae collected from a hill stream in Jammu and Kashmir, India. It is the first report of the genus Alainites Waltz & McCafferty, 1994 from India. The new species is closely related to the Palearctic species A. muticus (Linnaeus, 1758), but can be distinguished from the latter by the length of the maxillary palp, the reduced number of spine-like setae on the margin between the prostheca and mola of the right mandible, the reduced tracheation in the tergalii, and by a reduced number of spines on the prolongation of the paraproct. With this record, the genus Alainites encompasses a total of twenty-two species.
The ant genus Vollenhovia Mayr, 1865 (Myrmicinae, Crematogastrini) mostly occurs in the Australasian and Oriental regions. We revised its diversity in India and Sri Lanka based on qualitative and quantitative morphology, recognizing eleven taxa, including a new species which is described herewith: V. escherichi Forel, 1911, V. gastropunctata Bharti & Kumar, 2013, V. karimalaensis Dhadwal et al., 2023, V. keralensis Kripakaran & Sadasivan, 2022, V. mawrapensis Dhadwal et al., 2023, V. oblonga laevithorax Emery, 1889, V. penetrans (Smith, 1857), V. pfeifferi Bharti et al., 2023, V. taylori Rilta et al., 2023, V. terayamai Rilta et al., 2023, and V. yasmeenae sp. nov. The subspecies status of V. oblonga laevithorax and its relationship with V. penetrans, whose type series does not contain workers, still requires to be assessed in the context of a broader revision including the whole Oriental region. The known distribution of the genus in the Indian subcontinent appears to be fragmentary, still requiring extensive sampling efforts. Four species are from the Western Ghats biodiversity hotspot in the southern Indian state of Kerala, one is endemic to the biogeographically related Sri Lanka, three are known from Eastern India near the border with Bangladesh, two are reported from the Andaman and Nicobar Islands, and one is restricted to the Himachal Pradesh in northern India. A comprehensive key of the known Vollenhovia species from India and Sri Lanka is provided.
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.
The species of the ant genus Strumigenys Smith, 1860 from Southeast Asia are reviewed based on recent sampling efforts as well as unreported historical material from southern mainland China, Japan, Taiwan, Thailand and Vietnam. We report 42 new species records for these regions. A total of 20 species new to science are described: S. anhdaoae sp. nov., S. claviseta sp. nov., S. crinigera sp. nov., S. decumbens sp. nov., S. delicata sp. nov., S. densissima sp. nov., S. doydeei sp. nov., S. fellowesi sp. nov., S. intermedia sp. nov., S. jaitrongi sp. nov., S. liuweii sp. nov., S. longidens sp. nov., S. mediocris sp. nov., S. rongi sp. nov., S. scutica sp. nov., S. strummeri sp. nov., S. xenopilus sp. nov., S. yamanei sp. nov., S. zanderi sp. nov. and S. zhenghuii sp. nov. The descriptions of the existing species S. elegantula (Terayama & Kubota, 1989) and S. nathistorisoc Tang et al., 2019 are revised. Strumigenys formosensis Forel, 1912 syn. nov. is synonymized with S. feae Emery 1895 in the light of recently collected specimens. Three species complexes are created within the S. leptothrix-group: elegantula-complex, leptothrix-complex and zanderi-complex, based on differences in dentition. A new species group, S. nathistorisoc-group, is introduced. The key to Strumigenys of East Asia (as Pyramica) by Bolton is partially revised to accommodate species from these species groups that were described since the publication of the key. Finally, the implication of our results to the region and the current limitation of species groups and complexes of the genus is discussed.
