Euclosiana crosnieri (Chen, 1989)

Kerala material examined. Neendakara, 08˚56'N 76˚32'E, 30–70 m, 5 June 2007, 1 ♂ (CW 27.2 mm) (DABFUK).

Remarks. Euclosiana crosnieri can be distinguished from the first of its two Indian congeners, E. rotundifrons (Chopra 1934) , by its smooth third thoracic sternite, longer apical process of first male gonopod and large reddish mark dotted with three yellow spots on the gastric region, and from E. nitida (Galil, 2003) , by possessing a rounded rather than a unidentate frontal margin and by the foliate apical process of the first male gonopod, which is bent at a right angle to the shaft, rather than being digitate (Galil 2003; Fig. 3 b, d).

Distribution. Philippines, Indonesia and Queensland, Australia (Galil 2003). New record for India.
