( Figs 1B, F , 2D, I ). 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 ). Genitalia are also clearly distinguishable ( Figs 8C, G , 9E , 10A , 11B, F, L, P ). Etymology The specific name is a Latinized adjective formed after Povila, the type locality where the species has been collected. Type material Holotype NEW CALEDONIA (N): ³, Pic d’Amoa (Povila), -20.95020 165.29320 , 400–450 m , rainforest, 17 Nov. 2010 , R. Ruta and M. Wanat leg. ( MNHN ).

Description of the holotype (³) Body thickset, slightly convex ( Fig. 2D ); 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 ); 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 ) 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.
