Remarks.

The species can be separated from other members of the genus by having a comparatively low AR (0.31-0.46), macrotrichiae forming streaks in the apical half of the wing, squama with 4-5 setae, and anal point with bare apex and 3-4 setae on each side. The species was described from Australia by Kieffer (1917) as a member of Metriocnemus van der Wulp, and was transferred to Parametriocnemus Goetghebuer by Freeman (1961). The specimens from China are in accordance with the original description, but have a lower LR and AR than specimens from India. The differences between specimens from China and India are listed in Table 3.

Distribution.

The species has been recorded from Australia ( Kieffer 1917) and India ( Hazra et al. 2002). It occurs in both Oriental and Palaearctic China.
