Diogenes spinicarpus Rahayu & Forest, 1995 View in CoL

Diogenes spinicarpus Rahayu & Forest, 1995: 406 View in CoL , figs. 6a–f, 7a–h (type locality: Tanjung Tiram , Ambon, Indonesia).

Material examined. 1 male, 1.6 mm ( MZB Cru 5219), Pulau Hantu , dive, 7–10 m, 16 December 2012 ; 1 male, 1.3 mm ( ZRC 2021.0219 View Materials ), st. SD143, east of Pulau Hantu , dive, 12 m, 13 May 2013 ; 1 male, 2.2 mm ( ZRC 2021.0220 View Materials ), Pulau Semakau , near mangrove, 10 November 2011 .

Distribution. Indonesia, Singapore; 0–10 m, in sandy substrate.

Remarks. Among the species of the Diogenes pallescens group, D. spinicarpus is recognisable by the short fourth segment of the antennal penduncles armed with a strong spine on the dorsodistal margin, the slender antennal acicles bearing two or three spines mesially, and the proximally inflated ocular peduncle with a similar dilated cornea. The specimens examined in this study agree well with the original description by Rahayu & Forest (1995) except for the right cheliped that has a prominent hiatus between dactyl and fixed finger. This species is recorded for the first time in Singapore waters.
