Abstract

A new genus and species of Euryrhynchidae is described from Kerala, India. This freshwater shrimp family was previously only known from northern South America and West Africa. Although the inclusion of the genus in Euryrhynchidae is unequivocal (e.g. shape of the accessory ramus of the antennular flagellum, frontal margin of the carapace, telson ornamentation), the presence of a number of unique characters makes the relative placement of the genus within the family unclear, but likely basal to the other genera. The new genus can be easily distinguished from all others within the family by these characters, e.g. the upper antennular flagellum and its accessory ramus being joined over three divisions, the presence of a reduced carpo-propodal brush and a well-developed branchiostegal groove.
