Notes. Known from Korea ( Zwick 1973a) and the South of the Russian Far East ( Zhiltzova 2003). Both sexes are easily identified by their genitalia.

Female. The female was first illustrated as Amphinemura sp. ( Zwick 1973a: fig. 16; repr. in Zhiltzova 2003: fig. 244) but Levanidova & Zhiltzova (1979) recognized it as the present species. Females are unmistakable because of a raised cone on the rear margin of S7.

The inner genital sclerites of a specimen from the Russian Far East, Khabarovski kraj, tributary to River Khor (my collection) are elongate, with a small strongly sclerotized half-tube in front and two tongue-shaped dorsal sclerotized pockets on top, and triangular lateral extensions.
