A new genus and species of pinnotherid crab from Karachi,northern Arabian Sea (Crustacea,Decapoda, Brachyura)

A new monotypic genus, Sindheres, is established to accommodate a new species, S. karachiensis, of pinnotherid crab from the northern Arabian Sea. The new genus resembles Nepinnotheres Manning, 1993 in having the dactylus of the third maxilliped inserted near the mid-length of the ventral margin of the propodus but it differs in having a sub-hexagonal carapace.
