Mclaydromia colini Guinot and Tavares, 2003

( Fig. 1A )

Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 45, 1 8 (CB 13.1×CL 15.0 mm including pseudorostral teeth), NSMTCr 30898.

Remarks. The female identified here as Mclaydromia colini agrees well with the smaller male from the Sahul Shelf recorded in the third part ( Takeda et al., 2022b: fig. 13C). The carapace, chelipeds, and ambulatory legs are wholly covered with short, thick, felt-like hairs, and the seemingly bidentate front with small median tooth and prominent pseudorostral tooth on each side. Denudation revealed the carapace anterolateral margin to be armed with two distinct teeth margined with irregular granules.

Distribution. Originally reported from New Caledonia at 14–62 m depth, and then from the Sahul Shelf, 49–52 m depth; now, from the South China Sea at 60 m depth.
