Fig. 73D
) with one small dark spot around 2r-rs&Rs vein; distal part of 2r-rs&Rs vein shorter than proximal part (4.5:9). Protarsomeres in following proportions: 6:2:4:9:18. Protarsomere 2 produced into hook. Protarsomere 4 longer than basal part of 5. Enlarged claw (
Fig. 70A
) with proximal prominence bearing one long bristle. Protarsomere 5 (
Fig. 70A
) with inner side curvilinear, with distal region distinct from median and proximal regions, with basal part much shorter than apical part, with one row of 33 lamellae; apex with about 9 lamellae. Tibial spurs 1/1/2.
