Metasoma. T1 length/apical width ~ 1.3. T2 length/apical width 0.8-1.0. T3 length/apical width 0.6-0.7. Mid-longitudinal carina extending until basal ~ 0.7 of T3. Metasoma sculpture T1, T2, and basal ~ 0.7 of T3 rugose-costate, remainder metasoma smooth. Ovipositor sheath/hind basitarsus 0.25-0.40. Apex of ovipositor sheaths truncate and narrow; apical point absent.

Color (Figs 73-75 ). Brownish orange. Head light yellow with a dark brown spot dorsally from stemmaticum and along occipital carina on vertex (Fig. 74 ), and a brown spot on face, covering clypeus and part of face on each side of the clypeus; palpi dark brown. Antenna brown basally, lightening to light yellow medially, then darkening to brown apex. Pronotum mostly pale yellow except laterally brownish orange; anterior corner of mesopleuron pale yellow; propleuron mostly brown with light yellow borders. Legs with trochanter, trochantellus, most of tibia, and tarsomeres 1-4 whitish yellow; all fifth tarsi dark brown; all tibiae dark brown apically, dark region smaller in frontal and mid legs; hind trochanter and trochantellus with brown lateral spots. Wings weakly tinged brown, veins and stigma brown; fore wing with an infuscate oval spot around junction of veins 1M and 1CU (Fig. 75 ). Ovipositor sheaths black.

Male. Essentially as in female. Body length 6.8-7.0 mm, fore wing length 5.5 mm.

Diagnosis.

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 , 66 , 73 ). Aleiodes ovatus can be distinguished from both species by the oval infuscate spot on fore wing (Fig. 75 ). In the other two species dark coloration is present only along the veins (Figs 32 , 66 ) 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 ), whereas in A. brevicarina and A. maculosus the vertex does not have any dark brown markings (Figs 30 , 67 ).

Distribution.

This species is known only from localities in Brazil.

Etymology.

The name ovatus is Latin for oval or egg-shaped, being a reference to the distinctive oval marking on the fore wing in this species (Fig. 77 ).
