Prescutellar sulcus with complete mid-longitudinal carina, and a few irregular and incomplete carinae laterally. Mesoscutum posterior border with distinct complete carina. Metanotum with complete mid-longitudinal carina, sometimes interrupted at middle. Metanotum mid-pit present, delimited by carinae. Mid-longitudinal carina of propodeum complete, sometimes irregular apically. 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.

Ovipositor sheaths relatively narrow and truncate at apex; apical point very short, in most specimens hardly visible.

Color (Fig. 64 View Figures 64, 65 ). Brownish yellow. Antenna dark brown basally, gradually lightening toward yellow to light brown apex; scape ventrally lighter. Apex of hind tibia darker apically, varying from dark brown to only faintly darker; hind femur, and sometimes of mid femur, dark brown in some specimens. Tarsal claws brown. Wings tinged yellow; most veins yellow, infuscate spots at fore wing veins 1M/1CUa, r, apex of 1-1A and 2CUb, membrane around these veins distinctly infuscate; stigma mostly dark brown or entirely brownish yellow. Ovipositor sheaths dark brown.

Male. Essentially as in females with dark stigma and apex of hind femur and tibia dark brown. Body length 7.0 mm, fore wing length 5.5 mm; antenna broken, with 33+ segments.


Aleiodes mabelae   is similar to A. bakeri   in having the occipital carina interrupted mid-dorsally (Fig. 65 View Figures 64, 65 ), and the vein 1a absent from the fore wing. However, these two species are readily separated by the color of the antenna, which is dark brown basally in A. mabelae   (Fig. 64 View Figures 64, 65 ) but entirely brownish yellow in A. bakeri   (Figs 21 View Figures 21–24 , 22 View Figures 21–24 ). Also, the longitudinal carina of the propodeum is complete in A. mabelae   , whereas it is incomplete in A. bakeri   .


Specimens collected at higher elevations (~ 900-1000 m) have the stigma and all legs yellow, while specimens from lower elevations (~ 200-500 m) have the stigma mostly dark brown, and the apex of the hind tibia and femur dark brown.


This species is known only from localities in Peru.


This species is named in honor to our friend, and fellow entomologist, Mabel Alvarado, collector of most of the type specimens of this new species.
