Diagnosis. Females of this species have a tuberculate projection on S1 and males have an apically narrowed hind leg basitarsus, as in A. tenax sp. nov. Females of A. modica sp. nov differ from the latter by the metapostnotum posterior surface microreticulate, not rugulose, and by the smooth integument among punctures on mesoscutum and scutellum. The males of A. modica sp. nov. can be separated by the smooth posterior surface of metapostnotum, rugulose in A. tenax sp. nov.
