Diagnosis.

Body with dense hairy, head and mesosoma with engraved reticulate sculpture. Head subtriangular in frontal view; antennal scrobes deep, not reaching anterior ocellus; malar sulci distinct; antennal insertion obviously below centre of face; formula 11173. Head in dorsal view, occiput with horseshoe-like carina. Pronotum quadrangular; notauli complete, frenal line on scutellum indistinct; propodeal sculptures irregular; fore wing with pilosity, speculum absent; postmarginal vein longer than marginal vein. Gaster convex, petiole transverse, Gt1 and Gt2 large and smooth, ovipositor sheath exerted.

Hyperimerus is similar to Asaphes in the subfamily Asaphinae , but it can be recognized by the antenna with one anellus and seven funicular segments (two anelli and six funicular segments in Asaphes ), frenal line on scutellum indistinct (distinct in Asaphes ), petiole transverse (petiole longer than broad and with longitudinal ridges in Asaphes ).
