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 View Fig , 3C View Fig ). They are distinguishable from other Arsipoda species by the elongate antennae ( LAN /LB: ³ 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 View Fig , 10D View Fig , 11J, M, S View Fig ).

Median lobe of aedeagus ( Fig. 9G View Fig ) 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 View Fig ) with widely rounded basal part; collum moderately elongate, about twice as long as apical part; ductus quite short, apically inserted.
