, 324–325, male;

, 236–237, larva, case;
Tsuda and Akagi 1962
, 140, larva, case.
Adult. Body, wings, antennae yellowish brown. Head short, ocelli absent, anterior setal warts round in female, absent in male; posterior setal warts large and round. Antennae
6–8 mm
long; basal segment ca. 1.2 mm long, with long setae. In male maxillary palpi, distal segment banana-shaped in lateral aspect, membranous and elastic, bearing long pale setae on outer surface and pale scales on mesal surface; second segment membranous, oval, with long dark setae densely. Male abdominal sternite VI with 7–12 long spines, number and shape variable but usually central one longest. Female abdominal sternite VI bearing minute spines. Fore wing 6.5–8.5 mm long; in male, wheatear-like setae arise basocaudally.
Male genitalia. Segment IX long, oblique in lateral aspect; sternite IX slightly produced posteriorly, triangular in ventral aspect. Dorsal process of tergum X club-like in dorsal aspect. Paired ventrolateral processes asymmetrical, left one ca. 3/4 length as right one; both strongly sclerotized, apices usually acute, curved ventromesad. Preanal appendage very long, about as long as right ventrolateral process. Basal segment of inferior appendage large, oval, oblique. Distal segment of inferior appendage with 2 processes: dorsolateral process tapering to rounded apex in lateral aspect, rectangular in dorsal aspect, with concave mesal face; mesal process strongly screlotized, acute apex directed dorsad. Phallus simple, slightly arcuate in lateral aspect, distal end of ejaculatory duct open at apical fourth.
Female genitalia. Tergum X finger-like in lateral aspect; each apex triangular in dorsal aspect. Supragenital plate long. In lateral aspect, posterior margin of lamellae rounded dorsally, square ventrally. In ventral aspect, gonopod plate rounded, as long as wide, many setae on each side; apicomesal process triangular with a minute notch at apex. Spermathecal plate approximately half length of gonopod plate with pair of strongly sclerotized processes anterolaterally.
Larva. The larval stage of this species was described by
Tsuda and Akagi (1955)
for the first time.
