Diagnosis. Individuals of this species, in both sexes, are characterized by a strongly punctate metasomal terga, with a microsculpture on the integument that is weak or appears to be absent, and therefore, very bright. Females show an facial fovea that is clearly narrower in the lower half. Males are recognized easily by the length of A3, which is 1.4 times that of A4.

Comment. Often, the males of A. nana vary morphologically. For example, the color of the veins can vary from brown to black. The scutum has a microsculpture that can be present over its entire surface, or limited to a small region. However, the constitution of the male genitalia, a body with strong PPs, and an A3 almost 1.4 times the length of A4, clearly identify them.
