Variability. Known only from holotype.
Diagnosis. The species is very similar to A. stigmulifer sp. nov. by size and general habitus, but it differs from it mainly by having eyes larger and by prehumerus carinal and long. See also characters in the key.
Type material. Type locality: Myanmar, Yangon, Yangon [16°53'03”N, 096°08'35”E]. Type specimens. Holotype ♂ (EJCB): “ Rangoon ”.
Distribution. Myanmar (Yangon).
Etymology. The specific name is a noun in apposition, which is derived from the Latin noun stigma (mark) and the suffix - ula (small). The name refers to round spot on each elytron of the species.
