Taxonomic notes

Arsipoda yiambiae and A. paniensis sp. nov. are the only species with a pronotum clearly convex laterally ( Figs 4F , 5F ), but they are clearly different in color and size: A. paniensis sp. nov. is dark green, metallic, and larger; A. yiambiae is yellow and smaller. Genitalia are also easily distinguishable ( Figs 9D , 10C , 11K, R ). Median lobe of aedeagus slender ( Fig. 10C ); parallel in ventral view, distinctly enlarged at basal third, with triangular apical part; ventral sulcus thin and shallow; in lateral view median lobe curved at basal third, then straight; dorsal ligula narrow, fusiform. Spermatheca ( Fig. 11R ) with rounded basal part; collum very elongate (as long as basal part); length of apical part about half as long as collum; ductus elongate, thickset, apically inserted.

Biometry

Male (holotype): LE = 1.65 mm; WE = 1.04 mm; LP = 0.48 mm; WP = 0.82 mm; LAN = 1.12 mm; LAED = 1.05 mm; LB = 2.15 mm; LE/LP = 3.44; WE/WP = 1.27; WP/LP = 1.71; WE/LE = 0.63; LAN/ LB = 0.52; LE/LAED = 1.58.

Distribution

Collected in Northern and Central Grande Terre ( Fig. 15A ).
