NEWS - Researchers report Martin Kenne grasshopper ( Pteropera kennei sp. nov.), Danilo Matzke grasshopper ( Pteropera matzkei sp. nov.) and Alain Didier Missoup grasshopper ( Pteropera missoupi sp. nov.) which increases the number of Pteropera species in Cameroon from 8 to 12 and the total to 30 species in Central Africa. Pteropera Karsch 1891 is a genus of Afrotropical micropteran grasshoppers in the Catantopinae. These flightless grasshoppers are morphologically similar to Serpusia Karsch. Species of this genus are common in forests, forest edges and agrosystems, most of which have a restricted distribution range. The genus was originally described for Pteropera verrucigena Karsch and remained monotypic until the description of P. pictipes by Bolívar in 1908. In addition, P. karschi previously included in the genus Aresceutica Karsch 1896 was included in Pteropera by Donskoff (1981). Donskoff (1981) performed a complete revision of the genus based on external morphology, color...

NEWS - Researchers introduced Phasmadigonis Ramos-González & Parra gen. nov. for P. alba (Butler, 1882) comb. nov. and Gugnelve Ramos-González & Parra gen. nov. for G. butleri Ramos-González & Parra sp. nov. Digonis Butler 1882 was reviewed, D. cuprea Butler 1882 was synonymized with D. cervinaria (Blanchard, 1852), all varieties of D. punctifera Butler 1882 and D. cuprea were synonymized with their respective species. Phasmadigonis was established based on the type species Digonis alba Butler, 1882. This genus has similarities with Digonodes Warren 1895, Digonis Butler 1882, and Gonogala Butler 1882 because of the mucronate wing shape. However, Phasmadigonis can be distinguished by the presence of the Sc vein connected by a vein to a single accessory cell in the forewing and by the presence of the Sc+R1 vein connected to the radial bar by a weak vein in the hindwing. Phasmadigonis is distinguished by genitalia: V-shaped gnathos without lobes or spines, spatulate tra...

NEWS - Northern mayfly ( Branchiobaetis borealis sp. nov.) and Greater Bay mayfly ( Branchiobaetis megasinus sp. nov.) were described as new species based on the larval stage, Megabranchiella longusa Phlai-ngam & Tungpairojwong 2022 which was previously distributed only from Thailand, was recorded from China for the first time. Baetidae are distributed almost worldwide but are mostly diversified in the tropics. Southeast Asia, known for its expansive tropical rainforests and river systems that represent one of the most biodiverse ecosystems on Earth, is one of the richest hotspots for mayflies on a global scale. However, Baetidae have received less attention from taxonomists compared to those from Europe and North America. Although many Ephemeroptera taxonomists have made major contributions to the study of baetid fauna in the region, knowledge of baetid systematics is still limited and the diversity of baetid species in Southeast Asia is under severe threat of extinction due to ...

NEWS - Researchers report bizarre scale insect ( Barbenigma biza Powell & Miller, sp. nov.) and bush scale insect ( Barbenigma boscus Powell & Miller, sp. nov.), Hemiptera: Coccomorpha: Ortheziidae, two species of bizarre scale insects in a new genus from Florida and Nebraska, United States. Ortheziidae (Hemiptera: Coccomorpha) comprise 216 species in 24 genera; several of which are extinct and known only from specimens in amber. Barbenigma Powell & Miller, gen. nov., expands the concept of the Ortheziidae. Characters supporting placement in the Ortheziidae include: ventral thoracic spiracles; three pairs of abdominal spiracles; fused trochanters and femurs; large, well-developed anal ring; pores present in the ring surrounding the anal opening; modified quadrilocular pores; and differentiated apical setae on the antennae. The new genus shares many characters with the four species previously placed in Carayonemidae such as having fused trochanters and femurs; trochanters ...

NEWS - Two new species were described: tenuis leaf-beetle ( Euliroetis tenuis sp. nov.) and brick red leaf-beetle ( Euliroetis testacea sp. nov.), five species were redescribed and a new synonym was proposed: Euliroetis nigrinota Gressitt et kimoto, 1963 = Euliroetis simulonigrinota Yang 1992 syn. nov. based on examination of type specimens and morphology of male and female genitalia. Euliroetis was established by ogloblin (1936) for Aenidea ornata Baly 1874. Five species: E. abdominalis (Baly, 1874), E. lameyi (Laboissière, 1929), E. nigripes (Baly, 1874), E. ornata (Baly, 1874) and E. suturalis (Laboissière, 1929) were originally described in Aenidea Baly 1874, Liroetis Weise 1887 and Phyllobrotica Chevrolat 1836. The Nanling Mountains are an important mountain range and watershed in southern China on the border of Hunan Province, Jiangxi, Guangdong and Guangxi Zhuang Autonomous Region. These mountains stretch for about 600 km from east to west and about 200 km from north to...

NEWS - Island golden saxifrage ( Chrysosplenium insularis sp. nov.) in the Saxifragaceae from the southern islands of the Republic of Korea is morphologically similar to Chrysosplenium japonicum (Maxim.), differing in that it has fairly persistent bulbils, green to yellowish-green sepals, 4 stamens and cylindrical papillose seeds. Chrysosplenium L. is a perennial herbaceous member of the Saxifragaceae comprising over 70 species, mostly distributed in temperate regions of the Northern Hemisphere and shaded and moist habitats in mountains. Biogeographically, Chrysosplenium is known to originate from East Asia and several independent lineages have migrated to the New World. Thirteen species of Chrysosplenium are recognized on the Korean Peninsula ( C. flaviflorum, C. epigealum, C. ramosissimum, C. valdepilosum, C. aureobracteatum, C. barbatum, C. ramosum, C. grayanum, C. sinicum, C. macrostemon, C. japonicum, C. serreanum and C. flagelliferum ). During a floristic survey in southern Kor...

NEWS - Fanjingshan water penny beetle ( Mataeopsephus fanjingshanus sp. nov.) and Ming-zhi zhao water penny beetle ( Mataeopsephus zhaomingzhiis sp. nov.) collected using light traps from Guizhou Province, China. Psephenidae also known as water beetles include 300 species grouped into 5 subfamilies. Psephenid beetles are known in all zoogeographic regions and have high biodiversity in the Oriental Region. Larvae are fully aquatic, many of which have very flattened bodies to adapt to living in fast-flowing, clean water by feeding on algae covering rock surfaces. Adults with reduced mouthparts and short-lived can be found on vegetation or in litter and near rivers. Mataeopsephus Waterhouse 1876 includes 12 valid species and all are distributed in East and South Asia with 7 species recorded in China. The researchers added 2 new species collected using light traps. M. fanjingshanus has a distribution in Guizhou Province. All adults were collected with light traps at Fanjingshan Nature R...
