The great student of bugs Carl Stål described genus Repipta in 1859. Among the key traits are: an oblong head bearing two spines; front half of the pronotom constricted at the middle; first segment of the rostrum longer than the second; rear half of the pronotum bearing four spines; slender legs; and the last two segments of the tarsi unequal in length.

In males the third antennal segment is larger than it is in females. In both sexes the abdomen is not as long as the hemelytron. Also in both sexes the head is glossy and bears sparse, erect long hairs.

Martin-Park and colleagues (2012) revised the genus, redescribing the 13 known species and describing 12 new ones. The genus is Neotropical, with at least one species reaching as far north as the southern United States.

The photo shown here is the first documentation of R. antica outside of Brazil. It is a male of the species.

Photo location: Along the Rewa River, Guyana.
