Length of mesosoma about 1.5 times its height; pronotum smooth, crenulate anterior-dorsally; propleuron smooth; mesopleuron shining granular-coriaceous, centrally smooth, rugose anteriorly; precoxal sulcus present anteriorly and crenulate; antescutal depression absent, pronotal collar very shor and mostly smooth; mesoscutum finely granulate anteriorly, notauli wide and shallow, with strong crenulation anteriorly, posteriorly meeting in a depressed rugose area; scutellar sulcus with irregular mid-longitudinal carina; scutellum finely granulate; propodeum strongly rugulose, longitudinal carina short, present on anterior ¼; metapleuron granulaterugose; ventral midline of mesopleuron set within deep and crenulate sulcus.

Wings. Fore wing: vein r-m present, second submarginal cell relatively short, trapezoidal, vein 3-SR 0.75 times vein 2M; r:3-SR:SR1:2-SR:2-SR+M = 8:9:31:8:8; veins 1-SR+M very slightly sinuate; 1-M virtually straight; 1- CU1:2-CU1:cu-a = 5:34:6.

Color. Mostly yellowish; metasomal terga 1–3 dark brown, remaining terga light yellow; propodeum infuscated dark brown centrally; antenna dark brown basally and lightening on apical third, apical flagellomeres pale yellow; hind femur apical ¾ and hind tibia dark brown; all fifth tarsomeres brown; wings moderately infuscate.

Variation. Body size 4.7–5.9 mm, antenna with 49–55 segments. Propodeum and metasomal terga 1–3 color varying from entirely yellow to entirely dark brown; one female paratype from Brazil, Pará, have the flagellum entirely dark brown. One female paratype from Peru, Huanuco, have the hind wing vein m-cu postfurcal to r-m; in most specimens de m-cu is just antefurcal to interstitial, except for the holotype where it is distinctly antefurcal.

Male. Similar to female holotype, but metasomal tergite 3 at basal half granulate and with median longitudinal carina; antenna slenderer.

Distribution. Widespread over the Amazon Basin; known from Brazil, Colombia, Ecuador, French Guiana, and Peru.

Discussion. Aleiodes amazoniensis sp. nov., along with A. braeti sp. nov., A. choco sp. nov., A. donaldquickei sp. nov., A. gonzalezi sp. nov., A. tico sp. nov., and A. zaldivari sp. nov. form a distinct subset within the subgenus Athacryvac , chacterized by the vein m-cu of hind wing present, dorsally concave occiput, and relatively compact and short antenna. Aleiodes amazoniensis sp. nov. and A. donaldquickei sp. nov. are the only two species within this subset, and also within the Athacryvac , with transversely rugose vertex contrasting with the mostly smooth head. Differences between these two species are pointed under discussion section of A. donaldquickei sp. nov.

Etymology. The species is named after the Amazonian basin, where it is widely distributed.
