Actumnus squamosus (De Haan, 1835) View in CoL

Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 29, 1 ovig. $( CB 7.4×CL 5.7 mm), NSMT-Cr 30742.

Remarks. In the ovigerous female of Actumnus squamosus (De Haan, 1835) at hand, the carapace is thickly covered with short soft tomentum, and therefore the dorsal areolation is not visible. The three anterolateral carapace teeth are prominent, but only moderately protruded from the general outline of the carapace. The characteristic armature covering the surface of both cheliped palms is distinctive, agreeing with the photograph given by Takeda and Komatsu (2017: fig. 6A). The ovigerous female examined, with CB 7.4 mm, is smaller than the smallest ovigerous female ( CB 8.1 mm) from Kyushu, Japan, recorded by Takeda and Miyake (1969c).

Distribution. From Japan to India through the coasts of the West Pacific, including Australia, with bathymetric range from 10 to 324 m. Previous Australian records are from Queensland, so the current record extends the known Australian range to the northwest.
