On a new genus and new species of potamid crab (brachyura) from Burma

Abstract

A new genus and new species of potamid freshwater crab from Burma (present Myanmar), Flabellamon pretzmanni, is described. Flabellamon differs from other potamid genera in having a flat, transverse carapace with well developed epibranchial teeth which are separated from the external orbital angles by deep V-shaped clefts, and a short and relatively stout G1 which has a well developed fold on the dorsal margin of the terminal segment. The taxonomic status of two supposedly allied species, Potamon turgidulum Alcock, 1909, and Potamon kuehnelti Pretzmann, 1963, is also discussed.
