Coccobius species can be distinguished from all other genera of Aphelinidae as follows.Female. Body yellow to black; antenna often with some segments pale and others brown to dark brown; wings usually hyaline, rarely slightly and evenly infuscated. Antenna seven-segmented, with funicle three-segmented, clava two-segmented; mesopleuron large, undivided; mid lobe of mesoscutum large, with numerous setae, axillae small and widely separated, each with a single seta, scutellum with four to six setae. Fore wing without linea calva, often with narrow area basally asetose. Postmarginal vein absent or very short. Tarsal formula 5-5-5.
Male. Differing from the female mainly in genitalia and antennal shape. Antenna eight-segmented, funicle not differentiated from clava, flagellum uniformly coloured.
