Mesoscutum posterior border with distinct complete carina. Metanotum with mid-longitudinal carina complete, connecting to a carinate pit posteriorly, or carina bisecting posterior pit, although weaker posteriorly. Metanotum mid-pit present, delimited by carinae. Mid-longitudinal carina of propodeum complete, or nearly complete. Ventral mid-line of mesopleuron without sulcus anteriorly, shallow smooth sulcus present posteriorly; pit at ventral mid-line absent. Notauli weakly indicated anteriorly, indistinctly crenulate. Sternaulus weakly indicated anteriorly, rugose. Sculpture of mesosoma mostly granulate. Metapleuron rugose posteriorly. Pronotum rugose laterally, pronotal groove sparsely crenulate anteriorly, short subventral longitudinal carina present. Mesopleuron rugose below subalar groove. Subalar groove crenulate. Mid-posterior region of mesoscutum rugose, with a short mid-longitudinal carina posteriorly. Mesoscutellar trough entirely costate. Metanotum costate, or mostly smooth and weakly crenulate.

Wings (Fig. 35 View Figures 33–36 ). Fore wing: Stigma length/height 3.6-3.7. Vein r/2RS 1.2-1.4. Vein r/RS+Mb 1.3-1.4. Vein 3RSa/2RS 1.5-1.7. Vein 3RSa/2M 0.8. Vein 3RSa/3RSb 0.3-0.4. Vein 1CUa/1CUb 0.85. Vein 1CUa/2CUa 1.6. Vein 1cu-a weakly inclivous. Vein 1M weakly curved basally. Vein RS+Ma distinctly curved. Vein M+CU virtually straight. Vein 1-1A very weakly sinuate apically. Vein 1a absent. Second submarginal cell trapezoidal. Subbasal cell glabrous, with two parallel rows of short setae subapically, and a row of setae just below vein 1CUa and M+CU apically, plus a row of setae apically just above vein 1-1A. Basal cell mostly evenly setose, although setae sparser posteriorly, rarely with more or less large glabrous region posteriorly. Hind wing: Vein RS bent at basal 0.3, with vein r present. Marginal cell narrowest at base. Vein M+CU/1M 1.7-1.8. Vein M+CU/r-m 1.3-1.4. Vein m-cu present and pigmented, although not tubular. Vein m-cu position relative to vein r-m interstitial, or just antefurcal. Vein 2-1A absent. Basal cell evenly, rather sparsely setose, posteriorly with small bare area.

Hind legs. Femur length/width 5.0-5.3. Length of tibia/tarsi 0.85-0.95. Length of basitarsus/tarsi 2-4 0.75. Sculpture of hind coxa dorsally shiny granular-coriaceous. Tarsal claws not pectinate.

Metasoma. T1 length/apical width 1.1-1.2. T2 length/apical width 0.8-0.9. T3 length/apical width 0.65. Mid-longitudinal carina extending until basal 0.7 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 0.3-0.5. Apex of ovipositor sheaths truncate; apical point absent.

Color. Body entirely brownish yellow, including palpi and tegula. Antenna dark brown basally, gradually lightening toward light brown apex. All three femora apically dark brown, dark region larger at hind femur. Wings tinged yellow; most veins yellow, except vein 1M basally and 1CUa dark brown, apex of 1-1A brown, and veins r, 2RS, 3RS, 2M and part of 2CUb light brown; distinct infuscate spot around vein 1M, more faintly infuscate areas around veins r and 2CUa, and bellow apex of vein 1-1A; stigma varying from entirely yellow to mostly dark brown expect basal 0.3 yellow. Ovipositor sheaths dark brown.

Male. Essentially as in female with stigma mostly dark brown, although dark spot at stigma smaller. Body length 8.0-8.6 mm; fore wing 6.7-7.0 mm; antenna with 61 segments.


Aleiodes coariensis   is the only species in the A. bakeri   species subgroup with all femora at least partially marked with dark brown color (Fig. 34 View Figures 33–36 ). There is also a distinctive infuscate spot on the fore wing near the base of vein 1M (Fig. 35 View Figures 33–36 ). See the key for additional diagnostic characters.


This species is known from localities in Brazil and Peru (Amazonian region).


The name coariensis   refers to the municipality of Coari, in Amazonas State in northwestern Brazil, the type-locality of this species.
