Rhinolambrus contrarius (Herbst, 1804) Fig. 6B

Material examined.

1 young female (10.5 × 10.0 mm), 3 juveniles (largest 6.8 × 6.8 mm), 7°48.004'N, 77°27.754'E, 50 m.

Remarks.

Herbst (1804: 9) described this species from material from somewhere in the "East Indies" and as far as is known, the type is lost ( Sakai 1999). This is the type species of Rhinolambrus A. Milne-Edwards, 1878. The species has a wide Indo-West Pacific distribution (see Flipse 1930; Sakai 1976); and in India has been reported from various parts of Tamil Nadu and Andamans ( Henderson 1893; Jeyabaskaran et al. 2000; Kathirvel and Gokul 2010; Dev Roy and Nandi 2012; Vidhya et al. 2017).

The present materials are all juveniles, with none of the gonopod structures of the males developed even though the chelipeds are elongated. The pronounced “neck-like” constriction in adults of this species has still not developed (Fig. 6B).
