Antillocladius subnubilus (Sinharay et Chaudhuri) Mendes & Andersen, 2008

Mendes, Humberto Fonseca & Andersen, Trond, 2008, A review of Antillocladius Saether and Litocladius Mendes, Andersen et Saether, with the description of two new Neotropical genera (Diptera, Chironomidae, Orthocladiinae), Zootaxa 1887 (1), pp. 1-75 : 37

Antillocladius subnubilus (Sinharay et Chaudhuri) comb. n.

Parametriocnemus subnubilus Sinharay and Chaudhuri, 1979: 121 , Fig. 2 ; Chaudhuri and Guha (1987: 27); Chaudhuri et al. (2001: 344).

Material examined: Holotype as in Sinharay and Chaudhuri (1979).

Diagnostic characters: The male can be separated from all other members of the genus by having numerous apical setae on the wing membrane; setose squama; virga half as long as phallapodeme; acrostichals starting close to antepronotum, anterior simple and posterior scalpellate; anal point long, tapering, with moderately strong lateral setae; and inferior volsella prominent with anterior digitiform projection equally long as and partly covering rounded posterior lobe.

Remarks: Antillocladius pluspilalus , A. yakyijeus , A. scalpellatus and A. subnubilus are only separable on the size of the virga and the chaetotaxy of squama and cell m 3+4. See A. pluspilalus for comments.

Distribution: The species is known from West Bengal, India.
