Male terminalia: Sixth tergite entire, only weakly concave on anterior margin, with a row of setae on posterior margin; surstylus broad, nearly parallel-sided, weakly narrowed near apex, with dense hairs; cerci in dorsal view broad at base and strongly narrowed at basal 2/5, parallel-sided to apical 1/5, then narrowed to apex, with distinct mid-dorsal suture on basal portion and narrowly separated along apical 1/5, in lateral view well constricted at basal 2/5, then evenly curved ventrally; pregonite weakly pointed near median portion; postgonite not extending beyond epiphallus; dorsal sclerite of distiphallus flat, apical membranous portion short, about 1/4 as long as basal portion.

Female terminalia: Sixth tergite long, entire, with several discal setae and a row of marginal setae; 6th sternite with rather dense hairs on entire surface; 7th hemitergites long-ovate in form, with several setae on posterior portion; 7th sternite with rather strong hairs on posterior 1/2; 8th hemitergite rather long, broadly fused with hypoproct on median portion; 8th sternite nearly as long as 7th sternite.

Description of first instar larva. Body length 0.85–0.95 mm; cephaloskeleton rather broad on apical 1/2, dorsal margin weakly concave at middle; 2nd thoracic segment with 3–4 anterodorsal rows of fine spinules; 2nd to 6th abdominal segments each with 5–7 posteroventral rows of short fine spinules, 7th segment with a complete posterior row of spinules.

Distribution. Japan (Hokkaido, Honshu, Shikoku, Kyushu).

Remarks. This species appears to have several generations in Japan between late spring and late autumn. Mesnil (1957: 71) stated that the holotype is a male, but it is in fact a female.
