Bellinympha Wang et al., 2010

( Figs 65 E–F)

Type species. Bellinympha filicifolia Wang et al., 2010: 1 (by original designation).

Diagnosis. Wings subtriangular, posterior margin irregularly sinuous distally in FW, mostly straight in HW; both wings with distinct markings or infuscation, FW with prominent pinna-shaped markings along entire length centred along medial vein; FW subcostal veinlets irregularly forked; both wings with RP arching in apical part of wing, two to five regular rows of cells present in RA area, distal branches of RP apically curving toward posterior margin, RP with six branches before distal curve anteriorly; MP with numerous pectinate branches; CuA with regular pectinate branches.

Comments. This genus has apically truncated, subtriangular wings where the forewing has a sinuate posterior margin. The disruptive pattern of colouration that resemble leaf pinnae, as well as thickened MP vein superficially resembles a leaf rachis (see discussion by Wang et al., 2010) makes this genus readily distinguishable from other genera in the family. There is an appendage close to the caudal segment that resembles the female gonocoxite 9 of Osmylidae , lending additional support to the close relationship of these two families.
