Stictochironomus exterflexus ( Hazra, Sanyal and Brahma, 2015) View in CoL Comb. n.

Polypedilum (P.) exterflexus Hazra, Sanyal and Brahma, 2015: 2 View in CoL ; Hazra, Niitsuma and Chaudhuri, 2016: 89.

Material examined. Holotype male labelled ‘( BUENTD 273 ), India, West Bengal, Hooghly, Tribeni (22.98, 88.38), 19.iii.2001, Coll. U.K. Mandal’ ; 1 male data same as holotype.

Remarks. The species Polypedilum exterflexum Hazra, Sanyal and Brahma has previously been unplaced subgenerically. But after careful study, it has been found to belong to the genus Stictochironomus Kieffer. The combination of these characters in the male imagines justifies the inclusion of P. exterflexum Hazra, Sanyal and Brahma under the genus Stictochironomus : 1) wing membrane marked without setae, 2) anterior and posterior tibial combs of mid and hind legs fused, 3) T VIII not basally constricted and 4) inferior volsella bent laterad. The species differs from S. caffrarius Kieffer, 1921 in higher AR, shape of superior volsella and unmarked wings.
