Supplementary description.

Head dark brown. Antenna with dark brown second segment and others pale brown; length ratio of flagellomeres (I-XIII): 17-19 (17.6): 12-14 (12.8): 12-14 (13): 12-14 (13): 11-13 (12.2): 11-13 (12): 11-13 (12.4): 13-16 (13.8): 12-14 (13.4): 37-41 (38): 24-27 (25.6): 17-19 (18): 27-30 (29); AR 1.13-1.16 (1.14). Length ratio of palpal segments (I-V): 10-12 (10.6): 12-14 (13.2): 24-29 (26.6): 14-16 (15.4): 8-10 (8.8); PR 3.57-3.85 (3.72). WL 0.85-0.88 (0.86), WW 0.30-0.33 (0.32); CR 0.39-0.43 (0.4). TRI 0.81-0.87 (0.84), TRII 0.85-0.92 (0.87), TRIII 1.35-1.41 (1.38). Gonocoxite almost twice as long as wide bearing numerous setae, broad in middle and constricted at apex with well developed apicolateral process. Gonostylus little shorter than gonocoxite. Aedeagus almost triangular, basal arch shallow with apical and subapical serrations (Fig. 4 ).

Discussion.

Both palpal and hind tarsal ratios are lower than those of Chinese ones.

Distribution.

China, Taiwan, Australia and India (new record).
