Diagnosis.

PT 1.31-1.72 × Ant. VIb; URS 0.11-0.15 mm, long wedge-shaped (Fig. 8D), 1.75-2.68 × BW URS, 0.91-1.17 × HT II; ABD TERG VIII with conical supra-caudal (Fig. 8H), 0.65-1.14 × cauda; siphunculus 2.00-2.58 × of cauda (Chakrabarti and Das 2009).

Comment.

The species is recorded in China for the first time, and with some variations from the original description as follows: PT 1.27-1.40 × Ant. VIb; URS 1.15-1.28 × HT II; supra-caudal process 1.05-1.14 × cauda in Bhutan.

The species resembles Cavariella aegopodii but differs as follows: PT 1.31-1.72 × Ant. VIb ( C. aegopodii: PT 1.12 × Ant. VIb); URS elongate wedge-shaped, 0.91-1.17 × HT II ( C. aegopodii: URS wedge-shaped, shorter than HT II).

Biology.

The species was found feeding on Salix (Fig. 32G) and Apiaceae in China, and it also been described feeding on Salix in Bhutan (Chakrabarti and Das 2009). So, the species may migrate between the two plants.

Distribution.

China (Tibet), Bhutan.
