Color (Figs 73-75 View Figures 73–75 ). Brownish orange.

Wings weakly tinged brown, veins and stigma brown; fore wing with an infuscate oval spot around junction of veins 1M and 1CU (Fig. 75 View Figures 73–75 ). Ovipositor sheaths black.
Male. Essentially as in female. Body length 6.8-7.0 mm, fore wing length 5.5 mm.
Aleiodes ovatus is similar to A. brevicarina and A. maculosus in having a whitish yellow hind tibia with dark brown apex (as in Figs 29 View Figures 29–32 , 66 View Figures 66–68 , 73 View Figures 73–75 ). Aleiodes ovatus can be distinguished from both species by the oval infuscate spot on fore wing (Fig. 75 View Figures 73–75 ). In the other two species dark coloration is present only along the veins (Figs 32 View Figures 29–32 , 66 View Figures 66–68 ) and does not form a large spot. Also distinctive for A. ovatus is the mostly light yellow head with a dark brown vertex (except for orbits) (Fig. 74 View Figures 73–75 ), whereas in A. brevicarina and A. maculosus the vertex does not have any dark brown markings (Figs 30 View Figures 29–32 , 67 View Figures 66–68 ).
