description: Genus Neocarpia Tsaur & Hsu, 2003    
 Neocarpia Tsaur & Hsu, 2003: 440; Löcker et al., 2010: 17; Zhang & Chen, 2013b: 42; Zhi et al., 2017: 20.   
 Type species: Neocarpia maai Tsaur & Hsu, 2003, by original designation.   
 Description. Body size. Moderate-sized species. Body strongly compressed laterally.   
 Head and Thorax. Head slightly narrower than pronotum in dorsal view. Vertex slightly widened to posterior emargination, broader than long and without subapical carina, lateral carinae moderately elevated. Frons with median carina; frontoclypeal suture generally angled or semicircular. Clypeus with well-developed median carina. Rostrum distinctly surpassing hind coxae. Pronotum short with intermediate carinae curved along posterior margins of eyes. Mesonotum tricarinate. Forewing in resting position steeply tectiform, widened towards apex, with rounded apical margin; Sc+R forming a common stem and M emerging separately from basal cell; position of fork Sc+R slightly basal or at the same level as fork CuA 1 +CuA 2; first crossvein MP -CuA 1 at least as long as MP 3+4 from MP fork to this crossvein, crossvein MP 3+4 -CuA 1 almost at same level as crossvein r-m, subapical cell MP 3+4 with upper margin (vein MP 3+4) fine concave, no crossvein between CuA 1 and CuA 2. Apical cells 10–11. Hind tibia lacking lateral spines.   
 3+4   
 Male genitalia. Pygofer symmetrical and prolonged with symmetrical lateral lobes in lateral view. Medioventral process thumb-like in lateral view.Anal segment tubular, short and stout. Gonostyli relatively small and symmetrical. Aedeagus slender and endosoma (=flagellum) of aedeagus with spinose processes.   
 Female genitalia. Ovipositor elongate, orthopteroid and slightly curved upwards; anal segment square or rectangular in dorsal view; tergite IX without wax plate. Gonapophysis VIII slightly sclerotised, blade-like posteriorly. Gonapophysis IX single, blunt and strongly sclerotised, between middle tooth and apex with a row of denticles. Gonoplac slightly sclerotised, with many spinules on ventral edge in inner lateral view. Posterior vagina with sclerites.   
 Distribution. Sino-Japanese, Oriental and Australian regions.   
 Remarks. According to the original description of Neocarpia Tsaur & Hsu, 2003 and figure of the type species N. maai, in particular the feature of the forewing venation namely “transverse veinlet M 3+4 -Cu la (MP 3+4 -CuA 1) much longer than vein M 3+4 (MP 3+4) from M (MP) fork to this veinlet, subapical cells M 3+4 (MP 3+4) with upper margin (vein M 3+4) weakly concave, no transverse vein between Cu l and Cu 2 ” and relative position of crossveins MP 3+4 -CuA 1 and r-m, it is highly likely that Neocarpia Tsaur & Hsu is a synonym of Eucarpia Walker. However, since we have not seen the type specimen, in this study we do not formally synonymise the two genera until the types become available for study.
