Pseudolambrus bidentatus ( Flipse, 1930) View in CoL

( Fig. 13A–B View Fig )

Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 29, 1Ə ( CB 24.5 mm including branchial posterolateral spines×CL 23.9 mm in median line), NSMT-Cr 30729.

Remarks. The male of Pseudolambrus bidentatus examined ( Fig. 12A–B View Fig ) agrees completely with the original description and figure, being characterized by a mesogastric tubercle rather directed posteriorly, a sharp keel from a small tubercle at the median part of the branchial region toward the posterolateral outgrowth, the hepatic and branchial margins fringed respectively with three and seven thin lobes, and a thin lobe of remarkable size at the basal part of the outer margin of each palm. As noted by Takeda and Komatsu (2015), this species is in the group of Pseudolambrus having the rather depressed and triangular carapace armed with a strong mesogastric tubercle; P. harpax ( Adams and White, 1848) , P. confragosus ( Calman, 1900) , P. bispinosus ( Rathbun, 1902) , P. lobatus ( Flipse, 1930) , P. bicornis ( Flipse, 1930) , and P. incisus Takeda and Komatsu, 2015 . This species is readily differentiated from them by the characters mentioned above.

Pseudolambrus bidentatus was originally described as Lambrus (Pseudolambrus) confragosus var. bidentatus based on two females, one of which is ovigerous, from the Moluccas, Indonesia; Ng et al. (2008) raised the taxon to full species status.

Distribution. Moluccas, Indonesia, and now from northern Australia; 32–52 m depth.
