Miers, 1886
Carapace subpyriform, deeply channelled above, and armed with strongly projecting lateral branchial spines. Rostrum composed of two slender, slightly divergent spines. A distinct (although small) preocular tooth.
Post-abdomen (in the female) distinctly seven-jointed. Eyes mobile. Basal antennal joint little broader at the base than at its distal extremity, which is unarmed; flagella of the antennae inserted beneath the bases of the rostral spines and scarcely visible from above. Third maxilliped with its antero-external angle somewhat produced and rounded, its antero-internal angle slightly emarginate. Chelipeds (in the female) small, with the palm slightly compressed; fingers acute. Ambulatory legs of moderate length, with the penultimate joint not dilated; the terminal joint not denticulated on its inferior margin. This genus must be placed in the third section of my subfamily Acanthonychinae of the family Inachidae, and is most nearly allied (it would appear) to the genera Leucippe, Epialtus, and Eupleurodon in that section; from the first-named of which it is distinguished by the divergent spines of the rostrum and the distinct preocular spine; from the second by the different form of the carapace and rostrum, and from the third by the non-dentigerous ambulatory legs (Miers, 1886: 38).
