The G. conica species-group

Diagnosis. Species of the group are superficially distinguished from other congeners by their yellow forewing cilia, which are grey in the G. vietnamica and the G. typica species-groups. The male genital capsule of the species-group is characterised by the elongate and downcurved dorsal section of the valva which is almost twice longer than the sacculus, and the latter having a shortly triangular distal process directed dorsally. The lobes of the anellus are narrow and claw-shaped. The vesica structure is similar to the G. vietnamica species-group but the main chamber is narrower and tubular whereas it is proximally dilated and ventrally hook-like curved in the latter. The female genitalia of the two species-groups are similar but in the G. conica species-group, the corpus bursae bears two signa (vs. a single signum in the G. vietnamica species-group), and the appendix bursae is markedly smaller.
