Mesoscutum posterior border with distinct complete carina. Metanotum with mid-longitudinal carina complete, connecting to a carinate pit posteriorly. Metanotum mid-pit present, delimited by carinae. Mid-longitudinal carina of propodeum present at basal 0.7, absent posteriorly. Ventral mid-line of mesopleuron set within shallow smooth sulcus. Pit at ventral mid-line weakly indicated. Notauli weakly indicated anteriorly, indistinctly crenulate. Sternaulus weakly indicated anteriorly, rugose. Sculpture of mesosoma mostly granulate. Pronotum granulate ventrally, pronotal groove mostly crenulate, short subventral longitudinal carina present. Mesopleuron mostly rugose. Subalar groove crenulate. Mid-posterior region of mesoscutum rugose, with a short mid-longitudinal carina posteriorly. Mesoscutellar trough entirely costate. Metanotum mostly smooth, with one or two pairs of lateral carinae.

Metasoma sculpture T1 rugose, T2 and most of T3 striate-rugose, remainder terga granular-coriaceous. Ovipositor sheath/hind basitarsus ~ 0.4. Apex of ovipositor sheaths truncate; apical point absent.

Color. Entirely yellowish brown, except for stemmaticum black. Wings weakly tinged brownish yellow; veins and stigma yellow except 1M, 1CUa, apex of 1-1A, r, 2RS, 3RS, 2M and part of 2CUb brown; faintly infuscate areas around veins 1M, r and 2CUa, and bellow apex of vein 1-1A.

Male. Unknown

Diagnosis.

Aleiodes bahiensis is similar to A. hyalinus and A. santarosensis . These three species have the antenna entirely yellow (as in Fig. 18 ). Aleiodes hyalinus is easily distinguished by its entirely clear wings and evenly brown wing venation, while both A. bahiensis and A. santarosensis share similar wing markings: veins 1M, 1CUa, and part of 2CUb dark brown, darker than remaining veins, and the wing membrane around these veins, and below vein 1-1A apically, is weakly to distinctly infuscate (as in Fig. 19 ). Aleiodes bahiensis can be distinguished from A. santarosensis by having entirely yellow legs (Fig. 18 ), while in A. santarosensis the legs have tarsomeres 1-4 and at least the base of the tibia whitish yellow, contrasting with a brownish orange femur.

Distribution.

Known only from the type-locality in Bahia, Brazil.

Etymology.

The name bahiensis refers to Bahia State in northeastern Brazil, the type-locality of this species.
