Taxonomic notes

A. shirleyae is, along with A. geographica and A. gressitti sp. nov., one of the yellowish species lacking external morphological characters that allow a reliable identification. These species can be distinguished by relying on the morphology of genitalia ( Figs 8 H–I, 9I, 11G–H, O). Median lobe of aedeagus ( Fig. 9I ) in ventral view thickset, laterally subparallel, with narrower base; apical part widened, laterally rounded, with large median tooth; ventral sulcus V-shaped, clearly impressed median groove; in lateral view median lobe distinctly curved, with slightly sinuate dorsal and ventral sides; dorsal ligula from apical third to almost apex of median lobe of aedeagus, basally widened, then clearly narrower. Spermatheca ( Fig. 11O ) with pyriform basal part; collum very elongate (as long as basal part); length of apical part about half as long as collum; ductus short, apically inserted.
