Body length 8.6-9.0 mm. Fore wing length 7.0-7.2 mm.

Head. In dorsal view eye length/temple 4.1. Eye height/head width 0.39-0.43. Eye height/minimum distance between eyes 1.1-1.3. OD/POL 3.2-3.4. OD/OOL 2.6-3.4. Frons excavated. Frons lateral carina present in addition to W-shaped carina. Occipital carina dorsally complete and curved. Occiput in dorsal view weakly indented medially. Occipital carina ventrally nearly touching hypostomal carina. Mid-longitudinal crest at upper face present. Hypoclypeal depression/face width 0.4. Malar space/eye height 0.11-0.14. Face height/width 0.85. Clypeus height/width 0.69. Clypeus convex, granulate. Sculpture of head shiny granular-coriaceous. Face transversely rugose-striate, medially granular-coriaceous below crest.

Antenna. Antenna with 59 antennomeres. Antenna/body length 1.0-1.1. Scape/pedicel length 2.5. Length of first/second flagellomere 1.1. Fourth flagellomere length/apical width 1.1. Tip of apical flagellomere pointed.

Mesosoma. Length/height 1.45-1.50. Width of mesoscutum/width of head 0.7-0.8. Mesoscutum length/width ~ 1.0. Pronotal collar/vertex 0.6-0.7. Prescutellar sulcus with complete mid-longitudinal carina, and a few irregular and incomplete carinae laterally. 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 complete. Ventral mid-line of mesopleuron smooth, without distinct sulcus; pit at ventral mid-line weakly indicated. Notauli weakly indicated anteriorly, indistinctly crenulate. Sternaulus absent. Sculpture of mesosoma mostly granulate. Pronotum pronotal groove strongly 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 entirely costate. Metanotum mostly smooth, with one or two pairs of lateral carinae. Propodeum mostly rugose.

Wings. Fore wing: Stigma length/height 3.3-3.5. Vein r/2RS 1.6. Vein r/RS+Mb 1.4-1.5. Vein 3RSa/2RS 1.2-1.3. Vein 3RSa/2M 0.71-0.75. Vein 3RSa/3RSb 0.24. Vein 1CUa/1CUb 0.6. Vein 1CUa/2CUa 1.1-1.2. Vein 1cu-a vertical. Vein 1M weakly, evenly curved. Vein RS+Ma virtually straight. Vein M+CU weakly sinuate. Vein 1-1A strongly sinuate. Vein 1a absent. Second submarginal cell short and trapezoidal. Subbasal cell glabrous, with a row of setae just below vein 1CUa and a row of setae apically just above vein 1-1A. 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. Vein M+CU/r-m 1.4-1.5. Vein m-cu present and pigmented, although not tubular. Vein m-cu position relative to vein r-m interstitial. Vein 2-1A present, although very short (Fig. 58 ). Basal cell sparsely setose, bare posteriorly.

Hind legs. Femur length/width 4.8-5.3. Length of tibia/tarsi ~ 1.0. Length of basitarsus/tarsi 2-4 ~ 0.8. Sculpture of hind coxa dorsally granulate. Tarsal claws not pectinate.

Metasoma. T1 length/apical width ~ 1.2. T2 length/apical width 0.7. T3 length/apical width 0.55. Mid-longitudinal carina extending until T2 or basal 0.5 of T3. Metasoma sculpture: T1-2 rugose-striate, T3 granulate, remainder metasoma smooth. Ovipositor sheath/hind basitarsus 0.5-0.6. Apex of ovipositor sheaths roughly rounded; apical point present, although very short.

Color (Figs 55-57 ). Dark reddish brown. Palpi and tegula dark brown. Antenna mostly pale yellow, apex and base brown. All tibiae pale yellow with dark reddish brown apex, dark region larger in posterior legs; tarsi 1-4 whitish yellow, fifth tarsomere dark brown. Wings weakly tinged brown, veins brown, no infuscate regions. Ovipositor sheaths dark brown.

Male. Unknown

Diagnosis.

Aleiodes joaquimi differs from similar species with banded hind legs by its deep reddish brown color (Figs 55-57 ), absence of infuscate spots on wings (Fig. 55 ), hind wing vein 2-1A present, although short (Fig. 58 ), and vein 1CUb relatively long, ~ 1.7 times longer than vein 1CUa (no more than 1.25 times in other species). It is most similar to A. barrosi , and the differences between these two species are discussed in the diagnosis for A. barrosi .

Distribution.

The Atlantic Forest in Bahia and Rio de Janeiro states in Brazil

Etymology.

The name is an honorary patronym for Luiz A. Joaquim, one of the collectors of the holotype specimen.
