Male. Body fully distended; head laterally compressed; several pronotal setae broken off; right wings slightly spread, left fore wing broken off in the middle, left hind wing twisted and overlapping abdomen; legs folded under body or head, respectively, except for left mid and hind leg; pterothorax concealed by a bubble of air; tube at tip broken off.

Ocellar setae 42; postocular setae about 57. Pronotum, length 220; width 296; posteroangular setae about 50 (difficult to measure); epimeral setae 70. Pterothorax, largest width 284. Abdomen, length>915 (tip of tube missing); largest width 314 (segment IV); segment X (tube), length not measurable; basal width 52. Setae on tergite IX, s3 221 (others broken off at tips).
