Description.

Female macroptera (Fig. 2 ). With the character states given in the generic diagnosis above. Body golden-yellow except head, metanotum and clavus brown; antennal segments I-IV pale yellow, V yellow basally and shaded brown apically, VI brown with base slightly pale, VII and VIII brown (Fig. 5 ); fore wing slightly dusky except pale base and apex (Fig. 8 ); all legs yellow; prominent body setae pale to brown. Head wider than long; ocellar setae pair III situated at the tangent between the fore and hind ocelli. Postocular setae six pairs, pairs I and III subequal and the longest, pair V situated far from pair IV (Fig. 6 ). Antennal segment II without microtrichial rows, III-VI with microtrichial rows, III-IV with apical neck, III-V with pedicel (Fig. 5 ). Pronotum weakly sculptured with transverse striae (Fig. 4 ). Mesonotum sculptured with transverse anastomosing striae; campaniform sensilla present anteromedially. Metanotum with irregular transverse lines anteriorly, irregular reticulate sculpture medially, longitudinal striations laterally; campaniform sensilla present (Fig. 7 ). Abdominal tergite I transversely striate; II-VIII with a few striations laterally. Abdominal sternites without discal setae.
