diagnosis
Diagnosis. Orasema is the only New World genus in the subfamily Oraseminae and can be recognized from other orasemine genera by the following combination of characters: mouthparts present and fully formed, area just below the median ocellus without impression or pit, ocellar-ocular sulcus absent, scrobe without a pair of parallel impressions, male antennae without scape glands, transscutal articulation complete, if lateral aspect of the mesepisternum reticulate then at least weakly sculptured ventrally, if propodeal disc with median channel and smooth lateral areas then face with obvious rugose or reticulate sculpture and labrum with four digits, basal petiolar flange prominent, apex of the first valvula of the ovipositor usually with distinct lateral teeth but never with sinuate ridges. Orasema can be recognized from other New World eucharitid genera by the following combination of characters: anellus present, prepectus distinct and separate from the pronotum, first gastral sternite constricted with a transverse crenulate furrow separating a semicircular anterior region, ovipositor expanded and usually with a lateral line of teeth on the ventral valve and lateral teeth on the dorsal valve.

Orasema Cameron 1884: 104. Type species: Orasema stramineipes Cameron. Subsequently designated by Kirby 1886: 29. Notes: illustrations accompanying description of O. stramineipes mislabeled as O. flavipes. Kirby 1886: 29 designated O. flavipes as type species with O. stramineipes as lapsus calami. Contrary to remarks by Kirby, the description of O. stramineipes agrees with the figure of O. flavipes. Dalla Torre 1898: 361 reversed the usage of Kirby and treated O. flavipes as a junior synonym of O. stramineipes.
