NEWS - Guttulate freshwater fungus ( Paramirandina guttulata H.W. Shen, K.D. Hyde & Z.L. Luo, sp. nov.) is a morphologically striking hyphomycete species collected from a freshwater habitat in Dujuanhu Lake in Yunnan Province, China, at an elevation of 2500 m as new to science based on unique morphological features and combined phylogenetic analysis of LSU and ITS sequences. Paramirandina was introduced by Liu et al. (2023) to accommodate two lignicolous freshwater fungi from lotic habitats in Guizhou Province, with Paramirandina aquatica as the type species. This genus is morphologically similar to Heliocephala and Mirandina, but can be distinguished by the morphology of conidia and conidiogenous cells. During the investigation of lignicolous freshwater fungi from a highland lake in Yunnan Province, the researchers discovered the striking hyphomycete on submerged woody substrates. Detailed morphological descriptions and comprehensive phylogenetic analyses confirmed the distincti...

NEWS - Socoroma leafminer ( Cremastobombycia socoromaensis Vargas sp. nov. Lepidoptera, Gracillariidae, Lithocolletinae) from the dry highlands of the western slopes of the Andes in northern Chile with larvae mining leaves on the shrub Baccharis tola Phil. (Asteraceae) is the first record of Cremastobombycia Braun 1908 in South America. No Cremastobombycia species have been reported from South America. However, morphological examination revealed that a micromoth obtained from a leafminer collected in the arid Andean highlands of northern Chile was an undescribed species in this genus. C. socoromaensis was recognized based on wing pattern and genital morphology. The forewings of the male (3.6–3.7 mm long) are orange-brown and have indistinct creamy white markings: a short longitudinal subbasal line and three costal strigulae and two dorsal oblique strigulae. Although the female forewings (3.0–3.1 mm long) are also orange-brown with subbasal lines similar to those of the male, the fou...

NEWS - Ralph Holzenthal caddisfly ( Rhyacophila lignumvallis Graf & Rázuri-Gonzales, sp. nov.) from the island of Corsica (France) was established as a new species in the Rhyacophila tristis (Schmid 1970) group based on morphological analysis and the mitochondrial cytochrome c oxidase subunit I (mtCOI), including sequences from 16 of the 28 species in the group. Rhyacophila Pictet 1834 with 814 living and 30 fossil species is the largest genus of caddisflies in the world, distributed mainly in the northern hemisphere, but also in temperate and tropical India and Southeast Asia. One of the groups is the R. tristis group in the branch Rhyacophila invaria . R. lignumvallis is most similar to Rhyacophila pubescens Pictet 1834, Rhyacophila tsurakiana Malicky 1984, Rhyacophila ligurica Oláh & Vinçon 2021, Rhyacophila harmasa Oláh & Vinçon 2021 and Rhyacophila abruzzica Oláh & Vinçon 2021. However, R. lignumvallis differs in the shape of the X tergum, the dorsal arm ...

NEWS - Beautiful wing long-horned moth ( Torodora lichi Yu & Wang sp. nov.) similar to Torodora epicharis Park 2002, dense spine long-horned moth ( Torodora mici Yu & Wang sp. nov.) similar to Torodora reniformis Yu & Wang 2022 and Torodora silvatica Park 2007 were first reported from China. Torodora Meyrick 1894 is the largest and type genus of Torodorinae (Lecithoceridae). This genus is distributed in the Oriental, Palearctic, Ethiopia and Australia region containing more than 230 species with 88 species recorded in China. Now researchers describe two new species and the first report of T. silvatica from China. T. lichi has a distribution in Yunnan Province, China, externally similar to the Thai species, T. epicharis . It can be distinguished by the absence of a postmedian line on the forewings, in the male genitalia with a foot-shaped cucullus, and juxta with a triangular median process below the posterior margin. While T. epicharis has a postmedian line on the f...

NEWS - Brownish yellow false truffle ( Truncocolumella pseudocolumella L. Li, S.H. Li & Y. Wang, sp. nov.) established as a new species for science based on specimens found during a survey of hypogeous fungi in the Hengduan Mountains, Sichuan Province, southwest China. Truncocolumella Zeller 1939 a small genus of false truffles with the type species Truncocolumella citrina Zeller 1939. To date only T. citrina and Truncocolumella occidentalis Malençon & Zeller 1940 have been recognized. T. citrina is a common ectomycorrhizal species found in coniferous forests in North America. However, T. occidentalis is rare and has only been found in Canada. A single specimen was found in the Yala Mountains in western Sichuan Province, China. Two additional collections were later found in the same area. Western Sichuan Province, part of the Hengduan Mountains, is one of the most biodiverse regions in the world. T. pseudocolumella differs from other species in the genus Truncocolumella ...

NEWS - JoVonn Hill of Mississippi State University revised and established 16 new species of modest grasshopper (Agroecotettix Bruner 1908), a group of grasshoppers inhabiting open scrub, dry desert plains and scrub from central Texas to southeastern New Mexico, south to central Mexico. Bruner (1908) established the genus with the description of Agroecotettix modestus based on a female collected from Ciudad Lerdo, Coahuila, Mexico. Hebard (1922) added Agroecotettix aristus aristus and Agroecotettix aristus crypsidomus from Uvalde and Marathon, Texas, USA, respectively, resulting in three taxa. The new taxa described are Agroecotettix silverheelsi sp. nov., Agroecotettix xiphophorus sp. nov., Agroecotettix glochinos sp. nov., Agroecotettix texmex sp. nov., Agroecotettix cumbres sp. nov., Agroecotettix burtoni sp. nov., Agroecotettix moorei sp. nov., Agroecotettix chiantiensis sp. nov., Agroecotettix dorni sp. nov., Agroecotettix chisosensis sp. nov., Agroecotettix turneri ...

NEWS - Guangzhou fungus beetle ( Dichodontocis guangzhouensis sp. nov.) and larvae from Guangdong Province, China, were described as a new species to science similar to Dichodontocis uncinatus Kawanabe (1994) and Dichodontocis queenslandicus (Lawrence, 2016). Currently, only 3 species of Dichodontocis Kawanabe are known in the world. The type species, D. uncinatus is distributed in southwestern Japan (Yakushima Island). D. queenslandicus is found in the rainforests of Australia (Queensland). The new species is known from Guangzhou (Tianlu Lake Forest Park), China. D. guangzhouensis is similar to D. uncinatus with the elytral setae appearing more distinctly seriate and regular in that species than in D. guangzhouensis , both anal veins of the hindwing are absent, but in D. guangzhouensis the hindwing has apical color spots and the impression of the anterior margin of the pronotum of D. guangzhouensis is broad and deep and extends posteriorly, clearly beyond the base of the horn...

NEWS - Hongkan phintella ( Phintella hongkan Wang, Gan & Mi sp. nov. ♂♀) from Hainan Tropical Rainforest National Park, China, was established as a new species to science, closely resembling Phintella arcuata Huang, Wang & Peng 2015 and Phintella pygmaea (Wesołowska, 1981). The authors also described for the first time a female of Phintella liae Wang, Mi & Peng 2023 Phintella Strand 1906, one of the richest genera of Chrysillini Simon 1901, is represented by 82 species widely distributed mainly from the Oriental and Palearctic Regions. Like most salticid genera, taxonomic studies of the genus are limited by the high rate (over 34%) of single-sexed species known. In addition, the species are diverse in habitus and copulatory organs, indicating that the species should not be monophyletic and the current generic position of some members needs further revision. To date, 32 species have been recorded from China, 21 of which are endemic. The male P. hongkan resembles P. arcu...

NEWS - Latias mayfly ( Isonychia latias sp. nov.) from Guizhou Province, southwest China, was established as a new species to science based on all developmental stages with adults showing some characters that are uncommon in Isonychia, such as brown middle and hind legs, and pale stripes on the thorax. Isonychiidae is a monogeneric mayfly family represented by the genus Isonychia Eaton 1871 that includes 16 species distributed in the Nearctic region and 21 species distributed in the Palaearctic and Oriental regions. Recently, researchers conducted a preliminary investigation of the mayfly fauna in Guizhou Province, southwest China, and found an undescribed specimen.
