B. Subgenus Nymphrytria, subgen. nov.

Type species. As for the genus.

Diagnosis. From the preceding subgenus distinguished by the reduced number of apical spines of front- and midtibia and by the diffferent structures of subgenital plate and right phallomere.

Female characters. Tibia armament: [3.6.0][7.5.0][5–6.5.3–4], hindtibia ventrally towards the apical third broadened, more or less wedge-shaped, Fig. 2F; midtibia with 7 dorsal spines, as in the male in two longitudinal rows, Fig. 2G.—Tarsi: without a claw.
