DIAGNOSIS. — This species is most distinctive for its characteristic squarish lamella projecting from the ventral base of the male metafemur. In addition, the body is largely covered with fulvous setae; the head and mesosoma are densely punctured; the flagellum is fulvous ventrally except the basal three flagellomeres; the tegula is largely rufo-testaceous; the forewing membrane has a dark-infuscate mark extending from the marginal cell apex; the metasoma is black, the terga lack enameled bands, and the terga are largely smooth and shining amid coarse discal punctures and small, fine punctures on basal halves of broad marginal zones (apical halves impunctate) except T1 of female with punctures noticeably weaker and sparser. The Vietnamese populations all belong to the subspecies M. terminata terminata [M. terminata megaera (Gribodo, 1894) is found in Singapore and Indonesia].
REMARKS
Maculonomia terminata is exceptionally common in the northern and central highlands of Vietnam. This species is found across a broad elevational zone, ranging from a few dozen meters to 1600 meters.
