Goera spicata Schmid 1965 , 35, male.

Adult. Body, wings, antennae yellowish brown. Head short; ocelli absent; anterior setal warts contact with each other, forming single, bell-shaped wart; posterior setal warts large, oval. Antennae 5–7 mm long; basal segment ca. 0.8 mm long, with long setae. In male maxillary palpi, distal segment oval, membranous and elastic, with long setae on outer surface and dark scales on mesal surface, apical tube-like lobe present, finger-like, membranous and elastic. Male abdominal sternite VI with comb-like spines, usually central two long and finger-like. Female abdominal sternite VI with several minute spines, sternite VII with dark pigmented band on posterior margin. Forewings 6–8 mm long in both sexes.

Male genitalia. Segment IX oblique in lateral aspect; posteroventral part slightly produced, triangular in ventral aspect. Dorsal process of tergum X elongated, somewhat broad, setose apicodorsally, with pair of spine-like setae near apex. Paired ventrolateral processes slender, strongly sclerotized, slightly longer than dorsal process, usually with 2 subapical setae laterally, acute apices directed ventrally. Preanal appendage club-like. Basal segment of inferior appendage large. Distal segment of inferior appendage with 2 processes; dorsal process short, acute apically; mesal process long, curved dorsolaterad with apex acute. Phallus simple tube-like, slightly arcuate in lateral aspect, with a midventral protuberance; 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, slightly bilobed in lateral and ventral aspect. Gonopod plate slightly wider than long, slightly projected laterally at midway in ventral aspect, with relatively wide apicomesal process. Spermathecal plate rectangular, approximately 4/5 length of gonopod plate, with 2 finger-like transparent lobes anteriorly.

Larva. Larval stage of this species was associated with adult and pupal stages by Kagaya et al. (1998), but the morphology was not described. The immature stages of this species and those of other Japanese species will be described in a future work.
