Nieto, 19–23 April 2017, 1 ♀ (COZEM). Adult habitus. General body yellow. Head yellow with black mask-like marking, oval pale spot laterad to ocelli, lappets marked with black, antennae mostly black (Fig. 12). Median pronotal stripe yellow, wide; anterolaterally slightly paler (Fig. 12). Femora banded apical ¼ black, basal ¾ yellow, tibia and tarsi black. Wing membrane fumose, veins black. Male. Unknown. Female. Forewing length 12.0– 13.5 mm. Subgenital plate 4-bilobed, inner lobes larger, with deep and Vshaped posterior margin (Fig. 13). Transverse sclerite on sternum 9 well developed, laterally ear-like, with long setae. Larva. Unknown. Diagnosis. This species may be the female of A. bandido described above but no associated collections are available. The femora of all legs of this species are banded, whereas in A. bandido, the legs are black, except for the metathoracic leg which the femur is yellowish basally. The distinctive head pattern and small size distinguishes it from other known species from other than A. bandido and A. laru Gutiérrez-Fonseca, 2015. The latter species is smaller, the subgenital plate is bilobed with lobes of almost equal size and the black mask of the head is interrupted medially (see Gutiérrez-Fonseca, 2015, fig. 8 and fig. 13).
