Neolithodes indicus is a species of king crab found in the southeastern Arabian Sea.[1]
Appearance
[edit]N. indicus has a pyriform carapace whose dorsal surface is heavily populated with small spinules inbetween major, conical spines; at the longest in one of its female paratypes, it has been measured at 188.3 mm (7.41 in) in length and 169.7 mm (6.68 in) in width.[1] Its rostrum is about 3–10% the length of the carapace – excluding the rostrum itself – in large specimens.[1] Like the carapace, its chelipeds and walking legs are covered in small spinules, and its rear walking legs – which are the longest – have four major spines.[1] The chelipeds and walking legs are lighter in colouration than the carapace, however, which is a clay-like reddish-brown.[1] Its chelae have several small spines and are lined with rows of golden setae.[1]
On the underside, its short, cylindrical fifth set of legs are tucked under its abdomen and covered in bristles.[1] Except for the first segment which is sparsely populated with tubercles, the abdomen is covered in numerous evenly spaced spinules.[1] The median and submedian plates of the second segment of its abdomen bear large spines, as do the margins of the second through fifth segments.[1]
Distribution
[edit]N. indicus is known from three female specimens collected in the southeastern Arabian Sea off the coast of Thiruvananthapuram in Kerala, India from 2013 to 2014.[1] These three specimens were found at depths between 1,064–1,338 m (3,491–4,390 ft) in the mid-continental slope on a bathymetric protrusion known as the Terrace of Trivandrum.[1]
Taxonomy
[edit]N. indicus was described in 2020 by carcinologists Vinay Padate, Sherine Sonia Cubelio, and Masatsune Takeda.[1] Its genus name "Neolithodes" is derived from Greek and Latin and means "new stone-crab",[2] while its species name "indicus" is Latin for "Indian".[1] It is likely conspecific with Neolithodes alcocoki, a nomen nudum suggested in the 1980s,[1] and it was originally identified erroneously as Lithodes agassizii[a] by A.R.S. Anderson in 1896.[1][3] N. indicus most closely resembles N. brodiei from New Zealand, N. flindersi from southeastern Australia, and N. nipponensis from Japan and Taiwan.[1]
