Frons lateral carina present in addition to W-shaped carina. 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 0.37. Malar space/eye height 0.19. Face height/width 0.75. Clypeus height/width ~ 0.6. Clypeus convex, granulate. Sculpture of head vertex coarsely granulate, frons rugose. Face transversely rugose-striate at dorsal half, granulate medially.

Prescutellar sulcus with entirely costate, lateral carina oblique and nearly reaching anterior border. Mesoscutum posterior border with distinct complete carina. Metanotum with complete mid-longitudinal carina, carinate posterior pit bisected by carina. Metanotum mid-pit present, delimited by carinae. Mid-longitudinal carina of propodeum present and basal 0.5 or less. Ventral mid-line of mesopleuron set within shallow smooth sulcus; pit at ventral mid-line present, shallow. Notauli present anteriorly, shallowly and weakly crenulate. Sternaulus weakly indicated anteriorly, rugose. Sculpture of mesosoma mostly granulate. Pronotum rugose laterally, pronotal groove crenulate laterally, with two parallel subventral carinae. Mesopleuron rugose below subalar groove. Subalar groove sparsely crenulate. Mid-posterior region of mesoscutum rugose, with a short mid-longitudinal carina posteriorly. Mesoscutellar trough entirely costate. Metanotum costate. Propodeum mostly rugose.

Second submarginal cell rectangular, slightly widening toward apex. 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 1.5. Vein M+CU/r-m 1.5. Vein m-cu present, spectral. Vein m-cu position relative to vein r-m just antefurcal. Vein 2-1A absent.

Metasoma. T1 length/apical width ~ 1.2. T2 length/apical width 0.7. T3 length/apical width 0.6. Mid-longitudinal carina extending until basal 0.7 of T3. Metasoma sculpture: T1, T2 and basal 0.7 of T3 rugose-costate, sculpture weaker at T3, remainder metasoma smooth. Ovipositor sheath/hind basitarsus 0.55. Apex of ovipositor sheaths roughly rounded; apical point present, distinct.

Color (Figs 79-84 ). Brownish orange. Head and pronotal collar yellow, stemmaticum black. Antenna with basal 12 or 13 flagellomeres black, apical segments brownish orange; pedicel black; scape dark brown to black, ventrally brownish orange. Base of tibiae and tarsi 1-4 slightly lighter than remainder legs. Wings subhyaline; stigma and most veins orange to yellow; vein 1M almost entirely dark brown, veins 1CUa, r, 2RS, and apex of 2CUb brown; infuscate areas around base of vein 1M and below apex of vein 1-1A. Ovipositor sheaths dark brown.

Male. Unknown.

Diagnosis.

Aleiodes taurus is most similar to A. gonodontivorus . The main distinguishing characters are the differently shaped second submarginal cell, long and widening apically, with vein 3RSa 2.1 × longer than vein 2RS (Fig. 83 ), and the propodeum with very short longitudinal carina (Fig. 84 ) in A. taurus . In A. gonodontivorus the vein 3RSa is at most 1.7 × longer than 2RS (Fig. 44 ), and the longitudinal carina of propodeum is nearly complete.

Distribution.

This species is known only from the type-locality in Brazil.

Etymology.

The name is from the Latin word taurus meaning bull, being a reference to the collecting locality. The holotype was collected in a forest fragment at the research station of the Brazilian Agricultural Research Corporation - EMBRAPA, formerly a farm named Fazenda Canchim, in which a breed of beef cattle was developed, the Canchim, between 1940 and 1970. This area now comprises one of the largest remaining fragments of forest in the municipality of São Carlos.
