Diagnosis

Arsipoda povilaensis sp. nov. shares a thickset, ovoid body with A. atra sp. nov., A. evax and A. transversa sp. nov. ( Figs 1B, F View Fig , 2D, I View Fig ). It can be distinguished by the yellowish integuments ( A. evax is black and metallic, A. atra sp. nov. is black, and A. transversa sp. nov. is reddish); compared to A. transversa sp. nov., with which it can be more easily confused, it also displays a less transverse and less convex pronotum ( Fig. 5A, D View Fig ). Genitalia are also clearly distinguishable ( Figs 8C, G View Fig , 9E View Fig , 10A View Fig , 11B, F, L, P View Fig ).

Etymology

The specific name is a Latinized adjective formed after Povila, the type locality where the species has been collected.

Description of the holotype (³)

Body thickset, slightly convex ( Fig. 2D View Fig ); LB = 2.38 mm; maximum pronotal width at base (WP = 0.85 mm); maximum elytral width at basal third (WE = 1.18 mm). Dorsum yellowish, not metallic. Frons and vertex microreticulate and punctate; head grooves weakly impressed, not continued to postantennal region; genae and frontal carina short; antennae slightly longer than ½ body length ( LAN = 1.28 mm; LAN/LB= 0.54), basally yellow, gradually and slightly darker towards apex; LA:100:6 7:56:56:78:78:78:78:89:78:122. Pronotum trapezoidal, clearly transverse (LP = 0.51 mm; WP/LP = 1.66), laterally weakly convex ( Fig. 5A View Fig ); anterior angles distinctly prominent; antebasal transverse sulcus weakly impressed, slightly sinuate, without clearly distinguishable lateral fovea; pronotal surface microreticulate, with small and dense punctuation, similar to that on head. Elytra slightly elongate (LE = 1.73 mm; WE/ LE = 0.68), laterally clearly arcuate; punctuation quite small, but distinctly larger than on pronotum; interstriae very finely microreticulate and micropunctuate. Legs yellow; first pro- and mesotarsomeres distinctly dilated; adhesive setae present on ventral side of first pro-, meso- and, partially, metatarsomeres. Venter light brown; last abdominal ventrite laterally clearly incised, without special preapical impressions. Median lobe of aedeagus (LAED = 0.94 mm; LE/LAED = 1.83) ( Fig. 9E View Fig ) in ventral view laterally parallel, slightly narrower in pre-apical part; apex rounded; in lateral view median lobe curved at basal third, then straight; apex sinuate, ventrally oriented; dorsal ligula from half length to apical part of median lobe of aedeagus, narrow.
