Type species . Ctenocheloides attenboroughi Anker, 2010 , by original designation and monotypy. Diagnosis . Cardiac prominence present . Rostrum obsolete or obtusely triangular, flat, not reaching cornea. Maxilliped 3 merus with mesial spine at midpoint . Male major cheliped merus with oblique spine near midpoint of lower margin; propodus swollen, with fine pectinate fingers about as long as palm. Minor cheliped merus lower margin with spine at or near midpoint; propodus cylindrical, slightly swollen at midpoint, about twice as wide as long. Male pleopod 1 article 2 simple, tapering, without coupling hooks. Telson parallel-sided over anterior half, then tapering to evenly rounded apex. Remarks . The pectinate fingers on the major cheliped are a little longer than the palm, whereas in Ctenocheles the fingers are at least twice as long as the palm, and the spikes more pronounced. Three species are known ( Poore, 2015b ). Ctenocheloides boucheti is a sister taxon to two species of Ctenocheles in the molecular analysis (Robles et al., in press).
