Baccadromia gen. nov.

Type species. Dromia (Cryptodromia) bullifera Alcock, 1900 .

Diagnosis. Carapace about as wide as long, roughly pentagonal in outline, moderately convex, smooth; coarsely setose. Rostrum bearing strong acute, teeth; supraorbital margin armed with smaller tooth followed by strong postorbital tooth; anterolateral margin shoulder-like, armed with 1 or more strong teeth, converging gradually towards posterior margin. Chelipeds well developed, lacking epipods, carpus and propodus with prominent erect tubercles. Smooth rounded pearl-like tubercles, 1 on antennal article 2, 2 on sub-hepatic area and 1 on merus of third maxilliped. Female sternal grooves ending close together between chelipeds.

Etymology. A combination of, “bacca”, a Latin translation of “pearl” and the generic name “ Dromia ”, hence “ Baccadromia ”. This is an allusion to the facial tubercles found on this crab. Gender feminine. (See Remarks below which outlines the reasons for establishing a new genus.)
