Latopilumnus tuberculosus (Garth and Kim, 1984) View in CoL

( Fig. 17 View Fig )

Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 29, 1Ə ( CB 4.8×CL 3.3 mm), NSMT-Cr 30780; 1$ (4.8× 3.2 mm), NSMT-Cr 30781; 3ƏƏ (4.0×3.0 mm – 5.5× 4.3 mm), 3 $$ (4.2× 3.5 mm – 5.9×4.0 mm); 3 ovig. $$ (3.4×3.0 mm – 4.4× 3.6 mm), NSMT-Cr 30753.

Remarks. Only one male is in good condition ( Fig. 16A–C View Fig ), and a female ( Fig. 17D View Fig ) retains the left cheliped and two left ambulatory legs, but otherwise, nine carapaces (3 ƏƏ, 3 $$, 3 ovig. $$), the detached three chelipeds and some ambulatory legs remained in a vial. The setosity of the carapace dorsal surface is quite similar to the good male specimen, but in most of the specimens the anterolateral teeth are not so distinctly triangular in dorsal view, but tipped with a more or less recurved sharp tubercle. The remaining chelipeds are close to the female cheliped of Latopilumnus tuberculosus shown by Takeda and Komatsu (2020: fig. 4), having many obtuse or subtruncated granules on the carpus. The palm of the larger chela of the good male specimen is bare except for the basal marginal part, being different from the female cheliped palm.

Distribution. Originally described on a male from the vicinity of Jolo Island in the Philippines, 45 m in depth, and later from the Okinawa-jima and Ishigaki-jima in the Ryukyu Islands, and now from northern Australia, 45–150 m depth.
