Taxonomic notes
This species is similar in shape, sculpture and generally color to A. gomezzuritai sp. nov. and A. longifrons sp. nov. (Figs 2A, F, 3C). They are distinguishable from other Arsipoda species by the elongate antennae (LAN /LB: ♂ Ż 0.70, ♀ generally Ż 0.60) and the elongate frons with narrow frontal carina. The three species can be reliably distinguished by the shape of their genitalia (Figs 9B, G, 10D, 11J, M, S).
Median lobe of aedeagus (Fig. 9G) in ventral view fusiform, with small median tooth; ventral surface with shallow median groove; in lateral view median lobe slightly and regularly curved; dorsal ligula from half length to apical part of median lobe of aedeagus, tapered toward apex. Spermatheca (Fig. 11M) with widely rounded basal part; collum moderately elongate, about twice as long as apical part; ductus quite short, apically inserted.
