Oziotelphusa ganjamensis, a new species of freshwater crab (Brachyura: Gecarcinucidae) from south Odisha (Orissa) state, eastern India

摘要

A new species of freshwater crab of the genus Oziotelphusa Muller, 1887 is described based on specimens collected from a rice field near Balakrushnapur, Ganjam district in Odisha (Orissa) state, eastern India. Oziotelphusa ganjamensis n. sp. is easilydifferentiated from its congeners by a distinct first gonopod (Gl) having terminal segment bent outwards, whose tip is upturned and pointed, and subterminal segment relatively broad in the basal half to two-third portion and then sharply narrows to appear slender in distal half to two-third portion. A key to the Indian species of Oziotelphusa is also provided.
