Medetera plumbella species group

Diagnosis. Small species, about 2 mm; face and clypeus entirely dusted, monochrome, usually light-coloured; postoculars uniseriate; lateral scutellars reduced, hair-like, less than 1/3 length of median setae, or totally lost; 3 strong dorsocentrals; acrostichals small or microscopic; apical section of CuA1 at most 2 times longer than m-cu; legs mainly yellow, with fore coxa and femora entirely yellow; rarely fore coxa black or femora black at base; 1 or 2 small dorsal bristles at basal 1/3 of mid tibia; mid tarsi with long apicals on all segments. Members of related Palearctic micacea and annulitarsa species groups differ in distinctly heterochromous face and clypeus, with the face brown or greyish pollinose and clypeus more or less shining; Palearctic species of senicula and micacea groups differ from the plumbella group in mostly black femora.
