Frons lateral carina present. Occipital carina dorsally complete and nearly straight. Occiput in dorsal view nearly straight, not indented medially. Occipital carina ventrally meeting hypostomal carina. Mid-longitudinal crest at upper face present. Hypoclypeal depression/face width 0.36-0.37. Malar space/eye height 0.2. Face height/width 0.70-0.75. Clypeus height/width 0.70-0.75. Clypeus convex, granulate. Sculpture of head shiny granular-coriaceous. Face transversely rugose-striate around median crest.

Antenna. Antennal segments 48-49. Antenna/body length 1.1. Scape/pedicel length 1.7-1.8. Length of first/second flagellomere 1.2. Fourth flagellomere length/apical width 1.7-1.8. Tip of apical segment of antenna nipple-shaped.

Mesosoma. Length/height ~ 1.7. Width of mesoscutum/width of head 0.65. Mesoscutum length/width 1.2. Pronotal collar/vertex 0.9-1.0. Prescutellar sulcus with five distinct carinae. 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. Propodeum mostly rugose.

Second submarginal cell trapezoidal. Subbasal cell glabrous, with two parallel rows of short setae subapically, and a narrow patch of setae just below vein 1CUa. Basal cell mostly evenly setose, sparsely setose posteriorly. Hind wing: Vein RS bent at basal 0.3, with vein r present. Marginal cell narrowest at base. Vein M+CU/1M 1.5-1.6. Vein M+CU/r-m 1.3. Vein m-cu present, spectral. Vein m-cu position relative to vein r-m interstitial, or antefurcal. Vein 2-1A absent. Basal cell evenly, rather sparsely setose, posteriorly with small bare area.

Metasoma. T1 length/apical width 1.2-1.3. T2 length/apical width ~ 0.9. T3 length/apical width 0.6. Mid-longitudinal carina extending until basal 0.7 of T3. 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


Aleiodes bahiensis   is similar to A. hyalinus   and A. santarosensis   . These three species have the antenna entirely yellow (as in Fig. 18 View Figures 18–20 ). 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 View Figures 18–20 ). Aleiodes bahiensis   can be distinguished from A. santarosensis   by having entirely yellow legs (Fig. 18 View Figures 18–20 ), 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.


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


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