451887C47915FF9FFF217CA7FC4FF970.taxon	diagnosis	Diagnosis. Longicaudata belongs to the Tasnimocerus genus group of Oriental Idiocerini (Zhang, 2018) characterized by the transverse rugae on the crown and pronotum to which Dianica Zhang, Jogocerus Viraktamath, Niligiriscopus Viraktamath, Hyalinocerus Zhang & Li and Tasnimocerus Ghauri. Longicaudata differs from Dianica in having two subapical cells on the forewings and the connective expanded posteriorly. It differs from both Niligiriscopus and Tasnimocerus in having a well-developed anal collar of the pygofer, which is absent in the latter two genera. It differs from Jogocerus in lacking male pygofer processes, and from Hyalinocerus in having an elongate style lacking setae.	en	Zhang, Hui, Zhang, Xiaoxia, Tian, Mingqian, Zhang, Bin (2026): Redescription of the Oriental genus Longicaudata Dmitriev (Hemiptera, Cicadomorpha: Cicadellidae).

451887C47915FF9FFF217CA7FC4FF970.taxon	discussion	Remarks. Freytag (2013) described seven new species from Thailand under Longicaudata. Based on the available descriptions and illustrations, at least some of these taxa do not belong to this genus, but their type specimens were not accessible for examination. The original description of Longicaudata by Zhang & Wu (2000) was brief, with some characters inaccurately described or omitted, and included only a few line drawings without habitus photographs of the type species. These deficiencies have resulted in subsequent taxonomic confusion and controversy. The Thai species described by Freytag (2013) differ markedly from the type species in external morphology and male genitalia, and are more appropriately placed in other genera but the original descriptions and illustrations also lack important details. Although we are unable to propose new generic placements for Freytag’s species, we redescribe Longicaudata here based on two newly collected male specimens of L. trilineata, providing detailed morphological information, habitus photographs, and comprehensive illustrations of the male genitalia. These data allow a more precise redefinition of the generic characters.	en	Zhang, Hui, Zhang, Xiaoxia, Tian, Mingqian, Zhang, Bin (2026): Redescription of the Oriental genus Longicaudata Dmitriev (Hemiptera, Cicadomorpha: Cicadellidae).

451887C47915FF9CFF217A9DFCA1F85D.taxon	description	Male. Crown with three dark brown maculae: two small ones close to eyes and triangular one at median line on posterior margin. Face with irregular dark brown maculae close to median line, frontoclypeus with three longitudinal stripes: two on lateral margin, one close to median line. Pronotum with two round dark brown maculae near anterior margins. Scutellum with basal triangles dark brown, and pair of small dark submedial spots farther posterad. Forewing with a large dark brown spot on the costal margin. Male abdominal apodemes large and elongate tubular, basal portions close together; inner margins diverging gradually from about the basal two-thirds towards the apex; distal ends attaining the anterior margin of sternite VI. Male genitalia. Pygofer with ventral margin concave, inner process with bifurcate laterosubapical process; anal collar with a hook-shaped process. Subgenital plate, in lateral view, gently curved dorsad; in ventral view, gradually narrowed to apex, fringed with long setae. Style with distal apohysis very long and ventral margin with 3 to 4 teeth, with short lateral and mesal lobes near base, straight through most of length, gradually tapered to acute upturned apical process. Connective with dorsomedial keel well developed. Aedeagus curved dorsally, aedeagal shaft broad basally then narrowed and tapered to apex. Measurements (mm).

451887C47915FF9CFF217A9DFCA1F85D.taxon	discussion	Remarks. The type specimens of L. trilineata were not examined. However, based on the morphological descriptions and illustrations provided by Zhang & Wu (2000), the material collected from near the type locality can be confidently assigned to this genus and identified as L. trilineata. This identification is further supported by comparisons with illustrations of the type material presented in Xue’s (2017) doctoral dissertation. The Yunnan specimens lack the small triangular lateral processes at the apex of the aedeagal shaft reported for the type material. This discrepancy may result from deformation introduced during slide preparation or from differences in viewing angle, either of which can obscure minute structural features.	en	Zhang, Hui, Zhang, Xiaoxia, Tian, Mingqian, Zhang, Bin (2026): Redescription of the Oriental genus Longicaudata Dmitriev (Hemiptera, Cicadomorpha: Cicadellidae).
