Artur Taszakowski, Zdeněk Jindra, †Andrzej Wolski — Tue, 11 Feb 2025 10:33:24 +0100

Gryllofulvius Taszakowski gen. nov., a new remarkable genus of the subfamily Cylapinae, tribe Fulviini, is described from Madagascar. The new species Gryllofulvius gibbosus Taszakowski gen. et sp. nov. is documented with photographic images, SEM micrographs of the selected body parts, and female genitalic structures. The stridulatory device (embolial stridulitrum and metafemoral plectra) of the new taxon is described, and the stridulation in Cylapinae is discussed.

Is there anybody (new) out there? Seven new species of Ligidium (Isopoda, Oniscidea, Ligiidae) from the Southern Appalachians, eastern North America

Ernesto Recuero, Michael S. Caterino — Fri, 07 Feb 2025 08:47:51 +0100

In this study, we describe seven new species of Ligidium Brandt, 1833 from the Southern Appalachian Mountains based on morphological and molecular data: Ligidium enotahensis sp. nov., L. nantahala sp. nov., L. protuberans sp. nov., L. gadalutsi sp. nov., L. pacolet sp. nov., L. whiteoak sp. nov., and L. schultzi sp. nov. Our findings significantly enhance the known diversity of this genus in the Nearctic, particularly in eastern North America. Morphological diagnoses are primarily based on traits of the male pleopod 2 endopodite, while molecular data, including mitochondrial Cox1 and nuclear 28S and NaK genes, help delimit all newly described species. Together these genes reveal considerable genetic divergence among the new species and from previously described ones. Phylogenetic analyses revealed clear genetic distinctions among the new species, but did not resolve all relationships. Furthermore, we propose elevating three subspecies of Ligidium elrodii (Packard, 1873) to full species status based on consistent morphological differences, Ligidium chatoogaensis Schultz, 1970, L. hancockensis Schultz, 1970, and L. scottensis Schultz, 1970, thereby increasing the total number of Ligidium species to 68. This research underscores the high species diversity in the Southern Appalachians and the importance of integrating morphological and molecular approaches in taxonomy.

A new species of Acanthosaura Gray, 1831 (Reptilia: Agamidae) from the Truong Son Mountain Range, Vietnam

Wed, 05 Feb 2025 15:42:06 +0100

We describe a new species of the genus Acanthosaura Gray, 1831 from the Truong Son Mountain Range, southern Vietnam, based on integrative taxonomic analyses. Acanthosaura cuongi sp. nov. differs from its congeners by a combination of the following diagnostic characteristics: size moderate (snout-vent length: 79.4–104.61 mm); the absence of a diastema between the short nuchal and dorsal crest spines; vertebral crests composed of two rows of enlarged, keeled, pointed scales, arranged in a zipper line; various body coloration with light-green, orange-yellow, and light or purple-gray; black eye patch extending posteriorly to the anterior edge of tympanum. Maximum likelihood (ML) and Bayesian inference (BI) analyses using two mitochondrial genes (COI and Cytb) support the monophyly of Acanthosaura cuongi. Furthermore, the new species differs from the closest lineage consisting of A. coronata Günther, 1861 by having pairwise genetic distances of 11.58–12.11%, and have a maximal intraspecific distance of 0.35%. This is the 21^st species of Acanthosaura and the tenth species of the genus reported from Vietnam.

Description of three new species of genus Vacrothele (Araneae, Mygalomorphae, Macrothelidae) from China with notes on two taxonomic amendments

Yu-Lin Zheng, Yu Zhao, Zi-Zhong Yang — Mon, 03 Feb 2025 08:44:27 +0100

Three new species of the genus Vacrothele Tang & Yang, 2022 are described in detail from China: Vacrothele fuyuanensis sp. nov., Vacrothele jiangkouensis sp. nov. and Vacrothele baiseensis sp. nov. Two described species of the Macrothele are transferred to the genus, i.e., Vacrothele emei (Lin & Li, 2021) comb. nov. and Vacrothele taiwanensis (Shimojana & Haupt, 1998) comb. nov. A key to species of Vacrothele and a geographic distribution map are given.

Integrative description of two new species of the Xenylla maritima species complex (Collembola: Hypogastruridae) from Crete (Greece), with notes on the high intraspecific genetic divergence found in X. maritima Tullberg, 1869

Dariusz Skarżyński, Barbara Valle, Dariusz J. Gwiazdowicz, David Porco — Thu, 30 Jan 2025 09:45:48 +0100

A classical taxonomic analysis of materials from several European museums as well as our own collection along with the analysis of DNA barcoding data (cox1) allowed us to determine the taxonomic status of Cretan forms included in the recently revised Xenylla maritima complex. Two of them are recognized as distinct species: Xenylla ellisi sp. nov. and Xenylla schulzi sp. nov., and a new cryptic lineage was found within the morphological boundaries of the broadly distributed species X. maritima.

Two new species in the genus Atractides Koch, 1837 (Acari: Hydrachnidiae: Hygrobatidae), with the first descriptions of the female of two species from China

Yu-Hao Zhang, Hai-Tao Li, Zhan-Yu Hu, Jian-Jun Guo — Tue, 28 Jan 2025 09:29:16 +0100

In this paper, two new species of Acari are described, i.e., Atractides (Atractides) cardiacus Zhang & Guo sp. nov. and Atractides (Atractides) fodingensis Zhang & Guo sp. nov. Moreover, the females of Atractides (Atractides) bitergumus Zhang & Guo, 2023 and Atractides (Tympanomegapus) tergumus Zhang & Guo, 2023 from Hainan Province and Guizhou Province of Oriental Region in China are described and illustrated for the first time.

First record of the millipede family Haplodesmidae (Diplopoda: Polydesmida) from Colombia: two new species of Inodesmus Cook, 1896 from the Northern Andes

Mon, 06 Jan 2025 11:08:58 +0100

The millipede family Haplodesmidae is reported from Colombia for the first time, represented by Inodesmus mesibovi sp. nov. and Inodesmus miconiae sp. nov. Their presence in primary and secondary oak forests suggests their native origin in Colombia. This discovery represents the first record of the genus Inodesmus Cook, 1896 in South America, with potential implications of further records of the genus and family from the continent. We also present the first record of teratologies in haplodesmid millipedes.

Neurostigma Enderlein, 1900 (Psocodea: ‘Psocoptera’: Epipsocidae) from Brazilian Amazon Rainforest: new species and variations in forewings

Natália S. Reategui, José A. Rafael, Alberto M. da Silva-Neto — Fri, 03 Jan 2025 09:08:40 +0100

Five new species of Neurostigma collected in the Brazilian Amazon Rainforest are described and illustrated: Neurostigma alfonsoi sp. nov., N. patriciae sp. nov., N. angelicum sp. nov., N. spinosum sp. nov. and N. willkeniae sp. nov. The first record of Neurostigma for the Brazilian state of Rondônia is included, along with an unpdated distribution map of male specimens of Neurostigma. An updated identification key of males of the genus is provided. Now, the number of species of Neurostigma recorded for Brazil has increased to 12, with two of them also occurring in Colombia. With this study, we significantly contributed to the knowledge of the diversity of the genus, which increased to 19 species.

Issid planthoppers from Bach Ma and Phong Dien in Central Vietnam. I. Tribe Parahiraciini (Hemiptera: Fulgoromorpha: Issidae)

Jérôme Constant, Hong Thai Pham — Tue, 17 Dec 2024 08:56:44 +0100

Eight species of Issidae (Hemiptera: Fulgoromorpha) belonging to the tribe Parahiraciini, were collected in recent years in Bach Ma National Park and Phong Dien District in Thừa Thiên-Huế Province in Central Vietnam. A new genus Cyclopissus gen. nov. is erected to accommodate a new species Cyclopissus corticalis gen. et sp. nov. from Bach Ma National Park. Three new species of the genus Flavina Stål, 1861 are described: F. bachmana sp. nov. from Bach Ma National Park and Da Krong Nature Reserve (Quang Tri Province), and F. lami sp. nov. and F. quangi sp. nov. from Bach Ma. Two new species of the genus Pseudochoutagus Che, Zhang & Wang, 2011 are described: Ps. lindae sp. nov. from Bach Ma and Ps. trungi sp. nov. from Phong Dien. One new species of the genus Pusulissus Bourgoin & Wang, 2020, Pu. bachmaensis sp. nov., is described from Bach Ma. Gelastyrella litaoensis Yang, 1994 is recorded from Quang Tri and Thừa Thiên- Huế provinces in Central Vietnam and from Thanh Hoa and Ninh Binh provinces in North Vietnam, for the first time. These eight species represent the first records of the family Issidae for Thừa Thiên-Huế Province and hence, the Vietnamese fauna now counts 58 species in 13 genera. An identification key to the Vietnamese genera of Parahiraciini is given.

An updated subjective global checklist of the extant non-marine Ostracoda (Crustacea)

Claude Meisch, Robin J. Smith, Koen Martens — Fri, 13 Dec 2024 10:25:57 +0100

We present an updated global checklist of extant non-marine Ostracoda, covering taxonomic changes in the published literature up to 31st December 2023. The checklist is subjective, as apart from published taxonomic changes, also some additional alterations are proposed, including ten candonid tribes which are upgraded to subfamilies, six new combinations, one new name, five synonymies and one new taxonomic placement. The checklist presently includes 2420 accepted species in 295 genera, as well as 84 uncertain species that are too poorly described to be recognisable. We also provide the totals of species numbers for each taxonomic rank, from genera up to order, and numbers of species and endemic species in each of the world’s major zoogeographical regions.
