We here erect a new genus, Parasinea, to accommodate the type species, P. colombiensis, n. sp. and P. coronata (Stål), currently placed in Sinea. This genus is closely related to Sinea but can be distinguished easily by the spoon-shaped pygophore and the highly reduced parameres. Males of P. colombiensis can be distinguished from those of P. coronata by differences in the abdominal shape and genitalia (the female of P. colombiensis is unknown). Illustrations of the male genitalia, photographs of the dorsal habitus of both species, and distributional records of the two species are provided.
