Carapace less than twice as broad as long. Ocular peduncles extend beyond tip of external orbital angle for less than 36% of their length and for less than a distance equal to twice the length of the cornea; without any filament distal to cornea; three distinct antero-lateral carapace teeth; length of merus of cheliped less than carapace length; first pleopod with a short terminal process. (Davie 1997)
Carapace almost smooth, with feeble clumps of granules present on branchial regions; front deflexed, constricted between bases of ocular peduncles, with smooth margins, bilobed distally, median furrow shallow; lateral margins slightly converging, subparallel posteriorly, 3 well defined antero-lateral teeth, external orbital angle projects beyond the following teeth. Ocular peduncles long and narrow, cornea extending beyond tip of external orbital angle for less than twice its length. Central region of epistome with a pointed protuberance. Merus of third maxilliped smaller than ischium. Palm of male cheliped stout, outer face generally smooth, except for a row of minute granules along inferior margin, inner face with a mat of setae at base of immovable finger; immovable finger not deflexed, cutting edge with a strong, subacute tooth at about half its length; cutting edge of dactylus proximally with a large, quadrangular tooth. Meri of ambulatory legs with granular margins, and finely granular surfaces, a row of hairs along upper margin. (Türkay 1995)
