Taxonomic notes
Arsipoda isola is a light bronze, metallic species clearly distinguishable by the strongly impressed and unevenly sized punctuation of pronotum (Fig. 4D).
Median lobe of aedeagus (Fig. 9A) in ventral view laterally parallel, apically triangular, with a median tooth apically truncate; ventral channel wide, elongate, open in apical part, then partially closed; in lateral view median lobe straight and thickset; dorsal ligula strongly tapered, from apical third to almost the apex of median lobe of aedeagus. Spermatheca (Fig. 11I) with elongate, cylindrical basal part; collum slightly longer than apical part; ductus short, preapically inserted, with proximal part very close to spermathecal capsule.
