Taxonomic notes

Arsipoda agalma is quite different from the other species, mainly for the deep and elongate frontal grooves, generally continued to post-antennal region, and the weakly convex pronotum, with very large and strongly impressed punctures on disc ( Fig. 4A View Fig ). Median lobe of aedeagus variable ( Figs 8 View Fig A–B): in ventral view laterally generally parallel, or slightly narrower in apical third, with a thin median groove; apex from triangular to strongly pointed; in lateral view median lobe from thin to rather thickset, moderately curved; dorsal ligula elongate – from basal fourth to almost the apex of median lobe of aedeagus – wide, but thinner in apical part. Spermatheca ( Fig. 11A View Fig ) with rounded basal part; collum elongate, about twice the apical part; ductus thin, with straight and elongate proximal part.
