Frons lateral carina present. Occipital carina dorsally complete and curved. Occiput in dorsal view weakly indented medially. Occipital carina ventrally meeting hypostomal carina. Mid-longitudinal crest at upper face present. Hypoclypeal depression/face width 0.34-0.38. Malar space/eye height 0.16-0.17. Face height/width 0.7. Clypeus height/width ~ 0.6. Clypeus convex, granulate. Sculpture of head mostly granulate, vertex granular-rugose, frons shiny granular-coriaceous. Face mostly transversely rugose-striate, granulate medially.

Antenna. Antennal segments 54-61. Antenna/body length 1.1. Scape/pedicel length 2.4-2.6. Length of first/second flagellomere 1.2-1.3. Fourth flagellomere length/apical width 1.3-1.5. Tip of apical segment of antenna pointed.

Prescutellar sulcus with complete mid-longitudinal carina, and 2-4 pairs of rather incomplete carinae laterally. Mesoscutum posterior border with distinct complete carina. Metanotum with mid-longitudinal carina complete, connecting to a carinate pit posteriorly, sometimes bisecting posterior pit. Metanotum mid-pit present, delimited by carinae. Mid-longitudinal carina of propodeum present at basal 0.8, or complete. Ventral mid-line of mesopleuron set within shallow smooth sulcus; pit at ventral mid-line present, shallow. Notauli weakly indicated anteriorly, indistinctly crenulate. Sternaulus absent. Sculpture of mesosoma mostly granulate. Pronotum rugose laterally, pronotal groove curvedly crenulate anteriorly, short subventral longitudinal carina present. Mesopleuron mostly rugose. Subalar groove crenulate. Mid-posterior region of mesoscutum rugose with long and irregular mid-longitudinal carina. Mesoscutellar trough costate near scutellum. Metanotum mostly smooth, with one or two pairs of lateral carinae. Propodeum mostly rugose.

Wings. Fore wing: Stigma length/height 3.2-3.6. Vein r/2RS 1.5. Vein r/RS+Mb 1.4-1.5. Vein 3RSa/2RS 1.4-1.5. Vein 3RSa/2M 0.8. Vein 3RSa/3RSb 0.31-0.34. Vein 1CUa/1CUb 0.8-0.9.

Second submarginal cell short and trapezoidal. Subbasal cell glabrous, with two parallel rows of short setae subapically, and a narrow patch of setae just below vein 1CUa. Basal cell with more or less large glabrous region posteriorly, sometimes with sparse setae; costal and apical regions evenly setose. Hind wing: Vein RS bent at basal 0.3, with vein r present. Marginal cell narrowest at base. Vein M+CU/1M 1.6-1.7. Vein M+CU/r-m 1.4. Vein m-cu present, spectral. Vein m-cu position relative to vein r-m interstitial, or antefurcal. Vein 2-1A absent. Basal cell sparsely setose, bare posteriorly.

Hind legs. Femur length/width 4.7-4.8. Length of tibia/tarsi ~ 1.0. Length of basitarsus/tarsi 2-4 0.75. Sculpture of hind coxa dorsally granulate. Tarsal claws not pectinate.

Metasoma. T1 length/apical width ~ 1.1. T2 length/apical width 0.75. T3 length/apical width 0.6. Mid-longitudinal carina extending until basal 0.5 of T3. Metasoma sculpture T1 rugose, T2 and most of T3 striate-rugose, sculpture weaker at T3, remainder terga granular-coriaceous. Ovipositor sheath/hind basitarsus 0.1-0.2. Apex of ovipositor sheaths truncate; apical point absent.

Color. Brownish orange. Stemmaticum black. Antenna dark brown basally, gradually lightening toward brownish yellow apex; pedicel dark brown; scape dark brown, ventrally yellow. Wings weakly tinged yellow; stigma and most veins yellow but veins 1M at basal 0.7, 1CUa, apex of 1-1A and of 2CUb, and sometimes vein r brown to dark brown; infuscate areas around base of vein 1M and below apex of vein 1-1A. Ovipositor sheaths dark brown.

Male. Unknown

Diagnosis.

Aleiodes goiasensis is similar to A. nigristemmaticum (Enderlein) but differs by having the fore wing vein r distinctly longer than 2RS (Fig. 39 ), the occipital carina distinctly curved mid-dorsally (Fig. 38 ), and the hind femur relatively shorter (4.7-4.8 × longer than wide). In contrast, in A. nigristemmaticum specimens the fore wing vein r is approximately equal to vein 2RS length, the occipital carina dorsally is mostly straight or only slightly bent, and the hind femur is 5.5-5.7 × longer than wide.

Distribution.

Aleiodes goiasensis is known only from central Brazil.

Etymology.

The name refers to Goiás, a state in mid-west Brazil, and the type locality for this new species.
