Diagnosis. This species may relate to G. tungusensis  and G. nigrosoma  in having a pair of ventral processes of tergum X, but bilobed dorsal process of tergum X is unique among Japanese species in male. In female, long apicomesal process of gonopod palte is also distinctive.

Adult. Specimens available for this study are all teneral. Body, wings, antennae mostly brown, but probably darker. Head short; ocelli absent; anterior setal warts round; posterior setal warts large, oval. Antennae about 8 mm long; scape ca. 0.7 mm long, with long setae. In male maxillary palpi, distal segment long oval, membranous and elastic, with long setae on outer and mesal surfaces, setae on mesal surface with swollen apices. Male abdominal segment VI with 5 spines. Female abdominal segment VI with 3–5 minute spines. Forewings ca. 9 mm long in both sexes.

Male genitalia. Segment IX long, oblique in lateral aspect; slightly produced posteroventrally, triangular in ventral aspect. Dorsal process of tergum X weakly sclerotized, unpigmented, bilobed at apex in dorsal aspect; bearing a pair of ventral processes, slender, unpigmented, single seta at each apex. Paired ventrolateral processes slender, strongly sclerotized, acute apices curved ventromesad. Preanal appendage clublike. Basal segment of inferior appendage short; distal segment with 2 processes, dorsal process shorter than mesal one, blunt apically, mesal process slender, curved laterad. Phallus arcuate in lateral aspect, with a process at midway in each lateral side, phallic apodeme triangular in lateral aspect.

Female genitalia. Tergum IX distinct, triangular in dorsal aspect. Preanal appendages fused with tergum X, rounded in lateral aspect. Lamellae large, protrudeed posteriorly. Gonopod plate slightly wider than long, with prominent apicomesal process; spermathecal plate diamond-shape in ventral aspect.

Larva. Unknown.
