can be recognised and separated from all other alpheid genera by the combination of the following features: (1) frontal margin with a basally broad, distally acute rostrum and acute, usually mesially directed orbital teeth; (2) more or less reduced lateral corneas; (3) incisor process of the mandible with a conspicuous dark-brown spot (visible in external view of the mouthparts, and sometimes in lateral view through the carapace); (4) equal and symmetrical or subsymmetrical chelipeds, with a nonsculptured simple chela, with fingers unarmed or armed with teeth, and with the ischium bearing a row of spiniform setae on the dorsal margin; (5) second pereiopod with a five-segmented carpus, the first segment being the longest, while the third being longer than the second or fourth; (6) third and fourth pereiopods with merus usually bearing one to three spiniform seta(e) on ventrolateral surface, and with a simple, conical dactylus bearing stiff setae at about 0.7 dactylar length; (7) sixth abdominal somite without articulated plate distoventrally; (8) uropodal exopod with a strong triangular tooth laterally on the diaeresis; (9) uropodal endopod with a more or less developed subtriangular tooth on the distolateral margin.
