Color (Fig. 48 View Figures 48–50 ). Body reddish brown. Stemmaticum black (Fig. 49 View Figures 48–50 ). Tegula dark brown. Wings subhyaline, veins light brown and stigma honey yellow (Fig. 50 View Figures 48–50 ). Ovipositor sheaths dark brown.

Male. Essentially as in female. Body length 5.9-6.8 mm; fore wing length 4.9-5.7 mm; antenna with 45-51 segments.


Aleiodes hyalinus   is most similar to A. santarosensis   , but its wings are entirely subhyaline with all veins honey yellow to light brown, without distinct darker regions (Fig. 50 View Figures 48–50 ). By contrast, the wings are tinged with yellow and with dark markings in A. santarosensis   (Figs 76 View Figures 76–78 , 78 View Figures 76–78 ). The body is brownish orange or reddish brown in A. hyalinus   (Fig. 48 View Figures 48–50 ), as opposed to being entirely yellow in A. santarosensis   (Figs 76 View Figures 76–78 , 77 View Figures 76–78 ). The ovipositor sheath is mostly dark brown to black in A. hyalinus   (Fig. 48 View Figures 48–50 ), as opposed to being light brown in A. santarosensis   (Fig. 76 View Figures 76–78 ), and the basal cell is evenly setose in A. hyalinus   (Fig. 50 View Figures 48–50 ), while in A. santarosensis   the basal cell has a large bare area entirely lacking setae (Fig. 78 View Figures 76–78 ).


Aleiodes hyalinus   is known only from localities in Brazil.


The name hyalinus   is Latin for glass-like or clear being a reference to the lack of coloration in the wings of this species.
