Remarks.

The species can be separated from other members of the genus by having a short anal point with bare, rounded apex; triangular inferior volsella, and clavate antenna with numerous curved bristles apically. The species is similar to Parametriocnemus brundini Sinharay et Chaudhuri in the structure of the hypopgium; it has a short anal point with bare apex, while that in Parametriocnemus brundini is longer. The species was redescribed and figured by Lehmann (1979, figs 124-125). However, no data for the legs was given; lengths (in µm) and proportions of the legs of the Chinese specimens are therefore given in Table 4.

Distrubution.

The species has been recorded from Ethiopia (Abyssinia), Kenya, Uganda and Zimbabwe (Rhodesia) in the Afrotropical Region ( Lehmann 1979), and it occurs in both Oriental and Palaearctic China.
