ETYMOLOGY. — From the Latin, spina , spine, thorn, in reference to the numerous spines in the chelipeds. DISTRIBUTION. — New Caledonia , Norfolk Ridge, between 470 and 950 m . DESCRIPTION Carapace slightly wider than long,exclusive of rostrum. Gastric region well defined, moderately convex; three hepatic spines, first spine strong, near base of outer supraocular spine, two outer hepatic spines small and subequal in size. Cervical groove and its posterior branch distinctly marked; grooves separating cardiac and branchial areas weakly developed.Transverse ridges as illustrated,with short and dense short setae;anterior branchial region smooth, with few short squamiform striae;five transverse ridges behind cervical groove,first and second interrupted in cardiac region;third to fifth interrupted medially; some small striae on anterior half of branchial regions. Lateral margins convex, armed with six spines decreasing in size posteriorly, two anterolateral spines anterior to cervical groove; greatest width measured between penultimate lateral spines; first spine strong, more than half length of second supraocular spine, and clearly overreaching sinus between supraocular spines, clearly longer than second anterolateral spines ( Fig. 1A ). Strong distal spine in pterygostomian area. Second abdominal segment as illustrated; two transverse ridges, and some short striae on each side ( Fig. 1C ). Sternal plastron medially concave; pair of well developed median processes on anterior margin of third thoracic sternum; fourth thoracic sternum with prominent lateral spine and setiferous transverse ridges ( Fig. 1B ).
