Color. Brownish yellow or pale honey yellow. Antenna dark brown basally, gradually lightening toward brown or brownish yellow apex. Legs with same color as body, rarely hind femur mostly dark brown. Wings tinged brown, stigma and most veins light brown; fore wing veins 1M, 1CU, apex of 1-1A, 2CUb medially, r, and veins of second submarginal cell dark brown. Ovipositor sheaths dark brown.

Male. The only male paratype is very similar to the females with dark brown hind femur. Body length 7.8 mm; fore wing length 6.7 mm; antenna with 44 antennomeres.


Aleiodes barrosi   is similar to A. joaquimi   in that both species have the first subdiscal cell relatively long and widening apically (Figs 27 View Figures 25–28 , 28 View Figures 25–28 ), and both have the vein 1CUb 1.7-2.1 × longer than 1CUa (0.9-1.3 × in other species). These two species are easily separated by the mainly yellow body color in A. barrosi   (deep reddish brown in A. joaquimi   ), yellow palpi and tegula (dark brown in A. joaquimi   ), and entirely yellow tibia and tarsi (tibia basally and tarsi 1-4 white in A. joaquimi   ). Additionally, the hind wing vein 2-1A is absent in A. barrosi   (Fig. 28 View Figures 25–28 ), but present in A. joaquimi   (Fig. 58 View Figures 55–58 ).


Known from localities in Brazil, Costa Rica, and Peru.


The name is a patronym for Marina Moraes Barros Lutz, one of the collectors of the holotype specimen.
