NEWS - Sumbawa longhorn ( Nemophora sumbana Kozlov, sp. nov.), Timor longhorn ( Nemophora timorella Kozlov, sp. nov.), shining shade longhorn ( Nemophora umbronitidella Kozlov, sp. nov.), Wegner longhorn ( Nemophora wegneri Kozlov, sp. nov.), long brush longhorn ( Nemophora longipeniculella Kozlov, sp. nov.), and short brush longhorn ( Nemophora brevipeniculella Kozlov, sp. nov.) from the Lesser Sunda Islands in Indonesia. The Lesser Sunda Islands consist of two parallel, linear oceanic island chains, including Bali, Lombok, Sumbawa, Flores, Sumba, Sawu, Timor, Alor, and Tanimbar. The oldest of these islands have been continuously occurring for 10–12 million years. This long period of isolation has allowed significant in situ diversification, making the Lesser Sundas home to many endemic species. This island chain may act as a two-way filter for organisms migrating between the world's two great biogeographic regions, Asia and Australia-Papua. The recognition of a striking cli...

NEWS - Three-spot grass-veneer ( Glaucocharis triochellaris Matsui, Yagi & Hirowatari sp. nov.) and dull gray grass-veneer ( Glaucocharis plumbofascialis Matsui, Yagi & Hirowatari sp. nov.) from the Ogasawara Islands of Japan with adult, male and female genitalia and molecular phylogenetic analysis revealed a sister relationship between the two new species and the monophyly of Glaucocharis Meyrick 1938. G. triocellaris is easily distinguished from the other species by distinctive morphological features, such as three black spots on the margin, each enclosing a silvery white spot in the middle of the forewing; a valve with a strong hook-shaped protrusion emerging from the middle of the ventral valve margin and a phallus with hook-shaped apical spines curved ventrally on the male genitalia; and a circular spinous antevaginal lamella on the female genitalia. Although larvae were not found, adults emerged from various Bryopsida species collected on Hahajima Island. The larvae ma...

NEWS - Similis treehopper ( Smilidarnis similifasciatus McKamey sp. nov.) from Bolivia and French Guiana, closely resembles Smilidarnis fasciatus Andrade in being brightly colored but differs in metathoracic tibial chaetotaxy, male pygofer, first anal segment, aedeagus, and color pattern. Andrade (1989) assigned the genus Smilidarnis to the two new species without placing the genus in a higher taxon because both displayed features of Smiliinae and Darninae. The diagnosis was expanded slightly by McKamey (2023) to accommodate new variations found among the three new species. S. similifasciatus has a pronotum without suprahumeral spines; brightly colored with a mixture of orange, yellow, and black; most lateral yellow band bifurcates posteriorly, lower arm running nearly the entire length of the lateral margin. The specific name is a masculine Latin adjective based on the combination of “similis” (similar to) and the related species S. fasciatus . S. fasciatus and S. similifasciatus ...

NEWS - Tingzhou bramble ( Rubus tingzhouensis C.An & G.C.Lin, sp. nov.) from Fujian Province, China, established as new to science which is morphologically similar to Rubus swinhoei Hance with chloroplast genome is 156,311 bp long and consists of 132 unique genes, including 86 protein-coding genes, 37 transfer RNAs, eight ribosomal RNAs, and one pseudogene. Rubus L. (Rosaceae) established by Carl Linnaeus in 1753 originally consisted of only 10 species. Over 270 years of botanical exploration and taxonomic refinement, Rubus has expanded to include nearly 700 species. This expansion makes it one of the most species-rich genera among the antherioids. The genus covers temperate and subtropical regions of the Northern Hemisphere. In China alone, more than 208 species have been documented with 139 of them considered endemic. The high number of endemic species highlights China’s unique biodiversity and emphasizes the importance of conservation efforts to protect this species. R. tingzho...

NEWS - Dayaoshan leaf-litter toad ( Leptobrachella dayaoshanensis Chen, Yu, Meng & Qin sp. nov.) from Dayaoshan National Nature Reserve at elevations of 1000 and 1600 m in Jinxiu, Guangxi, China, was established as new to science based on phylogenetic analysis, morphology and bioacoustic data. L. dayaoshanensis was found in the evergreen forest of Dayaoshan Mountain. Adult males made calls near rocky streams between 19:00 and 24:00, but there were also instances where calls were heard during the day. Calls were heard from early March to late April. Currently, the new species is only found within Dayaoshan National Nature Reserve. The species name dayaoshanensis refers to the type locality, Dayaoshan Mountain. The researchers suggested the English name Dayaoshan Leaf Litter Toad and the Chinese name is Da Yao Shan Zhang Tu Chan (大瑶山掌突蟾). L. dayaoshanensis can be distinguished from its relatives by its medium size (mean SVL 27.9 ± 0.7 mm, range 26.6–28.9 mm in males; 34.4 mm in fe...

NEWS - Researchers report the results of a morphological, anatomical and phylogenetic study describing Nadia Roque (Roquea Loeuille & Antar gen. nov.), a new genus of Asteraceae from Brazil, to accommodate the new species multiphyllaries roquea ( Roquea multiserialis Loeuille & Antar sp. nov.). Roquea joins a growing list of Asteraceae genera recently described from Brazil, such as Maschalostachys, Lapidia Roque & S.C.Ferreira (2017), Lychnophorella Loeuille (2019), Archidasyphyllum (Cabrera 1959) Ferreira (2019) and Vickia Roque & Sancho (2020). The first collection of R. multiserialis dates back to 2018 by G. Martinelli during a Bromeliaceae collecting expedition. The area is currently being systematically collected by the efforts of the Centro Nacional da Conservação da Flora and by a group led by the project “Plano de Ação Territorial Espinhaço Mineiro” which aims to publish a book detailing the flora of the area. R. multiserialis is currently considered endemic ...

NEWS - Copaquilla moth ( Plutella copaquillaensis Vargas sp. nov.) newly recognized in the genus based on adult specimens raised from larvae collected on Neuontobotrys lanata (Walp.) Al-Shehbaz (Brassicaceae) in the arid Andean highlands of northern Chile. The new species resembles Plutella xylostella Linnaeus 1758 in wing pattern, but differs in genital morphology. Plutella Schrank 1802 (Lepidoptera, Plutellidae) is a widespread genus of moths containing 26 species. The larvae feed on plants in the Brassicaceae, except for a lineage endemic to the Hawaiian Islands, whose host plants are in the Capparaceae, a member of the Brassicales closely related to the Brassicaceae and Cleomaceae. The circumscription of Plutella is controversial because of the variation in genital morphology. Unlike the large number of studies on P. xylostella , many members of this genus are poorly known. Apart from the diamondback moth, only two species have previously been recorded in Chile, Plutella deltodo...

NEWS - Chengkou meshweaver ( Cicurina chengkou sp. nov. ♂♀), Daba Mountain meshweaver ( Cicurina dabashan sp. nov. ♂♀) and long hook meshweaver ( Cicurina longihamata sp. nov. ♂♀) from Daba Mountain National Nature Reserve in Chongqing, China, were added as new species to science in Cicurina Menge 1871. Daba Mountain National Nature Reserve is located in the southern Dabashan Mountains with many intersecting valleys. The heterogeneous habitats create conditions for independent evolution of species and have given rise to many endemic species such as ferns and flowering plants, including Botrychium sutchuenense , Asplenium humistratum , Primula phagosa , and the beetle Neobisnius chengkouensis . A comprehensive survey of the biological resource background of Chongqing Daba Mountain National Nature Reserve was conducted in 2011.
