Diagnosis. This species is closely related to G. s p i c a t a, but can be easily distinguished from the latter by broadened, paired ventrolateral processes of tergum X in male, and shorter spermathecal plate in female.

Adult. General morphology and coloration are very similar to those of G. s p i c a t a, and distinguished only by genitalic characters. Forewing 5.5– 7 mm long in both sexes.

Male genitalia. Segment IX similar to that of G. s p i c a t a but dorsal part shorter and anterior margin gently concaved in lateral aspect. Dorsal process of tergum X slender club-like. Paired ventrolateral processes strongly screlotized, about 1.3 times as long as dorsal process, middle to apical 1 / 4 part broadened, with acute apices directed ventromesally, usually with 2 setae near apices laterally. Preanal appendages club-like. Inferior appendages similar to those of G. s p i c a t a, but mesal process of distal segment more slender and twisted. Phallus similar to that of G. s p i c a t a.

Female genitalia. Terga IX and X similar to those of G. s p i c a t a. Lamellae large, triangular in lateral aspect, with angular ventroposterior corner in lateral and ventral aspects. Spermathecal plate similar to that of G. s p i c a t a, but about 2 / 3 length of gonopod plate and without lobes anteriorly.

Larva. Unknown.
