Camatopsis rubida Alcock and Anderson, 1899 View in CoL
( Fig. 14A–F View Fig )
Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 52, 1Ə (CB 10.1×CL 8.9 mm), NSMT-Cr 30942.
Remarks. The carapace ( Fig. 14A–B View Fig ) of the present specimen of Camatopsis rubida is subtrapezoidal and high, differing slightly in the pro- portional shape according to the photographing angles. The carapace dorsal surface, chelipeds and ambulatory legs are wholly covered with longish fine setae ( Fig. 14A–F View Fig ). In the male examined, the right cheliped ( Fig. 14E View Fig ) is larger, but slender, leaving a narrow gape between both fingers along their basal halves. In the small left cheliped ( Fig. 14F View Fig ), the palm and fingers are slenderer, being armed with small irregular teeth on both cutting edges and with a sharp spine at distal one third of immovable cutting edge. Both cheliped fingers are apparently different from the chelipeds of developing or mature males.
The known species of the genus Camatopsis are morphologically close to each other, with some degree of variation, and it is difficult to evaluate some records of C. rubida . According to Ng and Castro (2016) who illustrated the G1s of all the Camatopsis species, the records of C. rubida from the Gulf of Thailand by Rathbun (1910) and Indonesia by Serène (1964) still remain unclear, but the records of C. rubida from the South China Sea by Zarenkov (1972) and Chen (1998b) show clearly the correct identification, with the illustration of the G1. Recently, Mendoza et al. (2021) recorded C. rubida from Indonesian waters, with fine photographs.
Ng and Castro (2016) recorded numerous specimens from many localities, with the complete literature, many photographs and the detailed geographical information.
Distribution. The type locality is the Andaman Sea (349 m), and Ng and Castro (2016) recorded many specimens from the Andaman Sea coast of Thailand (36–53 m), Western Australia (101–407 m), Sumatra (179–660 m), Papua New Guinea (195–422 m), Queensland coast of Australia (56–695 m), New Caledonia (170–460 m), and Fiji (234–361 m). Chen`s record (1998b) from the Nansha Islands is based on specimens obtained from depths of 113 to 224 m.
