Mid-longitudinal carina of propodeum complete. Ventral mid-line of mesopleuron set within shallow smooth sulcus; pit at ventral mid-line absent. Notauli weakly indicated anteriorly, indistinctly crenulate. Sternaulus absent. Sculpture of mesosoma mostly granulate. Pronotum rugose laterally, short subventral longitudinal carina present.

Color (Fig. 66 ). Body mottled pale yellow, orange and dark brown. Head pale yellow, clypeus and part of face just above clypeus brown, mandibles pale brown with dark brown teeth. Antenna yellow. Mesosoma mostly pale yellow except propodeum orange; dark brown markings at propleuron and pronotum anteriorly, mesopleuron below subalar groove and ventrally, posterior corners of mesoscutum, and scutellum; metanotum and part of metapleuron pale brown. Metasoma orange, pale yellow ventrally. Wings slightly infuscate, most veins dark brown, costal vein brownish orange, basal veins yellow; stigma mostly dark brown with both tips whitish yellow; tegula brown or dark brown. Legs with trochanter, trochantellus, tibia and tarsi 1-4 whitish yellow; coxae and femora dark brown, but light yellow at base; fifth tarsomeres yellow; exceptions: hind coxa mostly brown, hind tibia with apical 0.25 dark brown.

Male. Very similar to female but fifth tarsomeres usually dark brown. Body length 7.1-7.9 mm, fore wing length 5.8-6.3; 49-52 antennomeres.

Diagnosis.

Aleiodes maculosus can be easily distinguished by its mottled pale yellow, orange and dark brown body colors (Figs 66-68 ). It is most similar to A. brevicarina , but differs in having the fore coxa dark brown, stigma dark brown (Fig. 66 ), palpi yellow to pale brown (Figs 66 , 68 ), face light yellow with mid-ventral brown spot which extends to clypeus and mandibles (Fig. 68 ), tegula infuscate (Fig. 67 ), and antenna entirely yellow (Fig. 66 ) (the antenna is basally dark brown in A. brevicarina ). Aleiodes maculosus has a complete longitudinal carina on the propodeum, whereas the propodeal carina of A. brevicarina is quite short, extending over less than half the length of the propodeum.

Distribution.

This species is known only from localities in Brazil.

Etymology.

The specific epithet maculosus is Latin for dappled or spotted, a reference to the mottled color pattern in this species (Figs 66-68 ).
