Genus: Eosembia Ross, 2007

Diagnosis. Male Eosembia are generally distinguished from other genera in the family Oligotomidae as follows: the anterior branch of the media (MA) is unbranched in the forewing and hindwing, the basal segment of the left cercus is slender and never lobed and the tenth abdominal tergite is completely divided. Males often are strongly bicolorous, being basically blackish brown except typically possessing a bright orange prothorax and bases of the forelegs. Distal segments of the antennae are commonly abruptly white, and setae are usually longer than the bearing segment. Terminalia with process of the left hemitergite (10LP) usually broad, aedeagus usually sclerotic and broadened caudally. Hind basitarsus lengthened, second papilla very small or absent. The female is large, robust, and richly pigmented. Distal antennal segments are usually abruptly white. The prothorax and certain leg segments in some species are bright orange, but entirely dark in others. Intersegmental areas of the thorax, coxae and trochanters are whitish. Hind basitarsus often has two ventral papillae.
