Fig. 4

Goera sp. GD: Tanida 1997; Tanida 2003, 379, male, larva.

Diagnosis. This species is very similar to G. akagiae sp. nov., but the male differs from the latter by slender ventrolateral processes of tergum X. The female of this species can also be distinguished from G. a k a g i a e by wider gonopod plate and spermathecal sclerite.

Adult. General morphology and coloration are similar to those of G. japonica and G. akagiae . Forewings 7–9 mm long in male, 7.5– 10 mm long in female.

Male genitalia. Segment IX similar to that of G. akagiae , but in ventral aspect ventromesal lobe rather slender and V-shaped apically. Tergum X as in G. a k a g i a e but ventrolateral processes slender in lateral aspect, apices acute with ventrolateral process. Inferior appendages similar to G. akagiae , but mesal process thicker than that of G. akagiae . Phallus simple, tubular.

Female genitalia. Tergum X similar to that of G. akagiae , but rather slender in dorsal aspect. Gonopod plate slightly wider than long, apple-shaped with rounded apicomesal process. Spermathecal sclerite about 1.5 time as long as wide, with paired lateral lip.

Larva. Indistinguishable from G. akagiae .
