( Figs 1B, F , 2D, I ). However, the new species can easily be distinguished from other species by its black, non-metallic integuments, and wide and flat elytral interstriae. Genitalia are also highly diagnostic ( Figs 8C, G , 9E , 10A , 11B, F, L, P ). Etymology The specific epithet is a Latin adjective that means black, dark. Type material Holotype NEW CALEDONIA (N): ³, Aoupinié , near Goipin rd jct [= road junction], -21.1739 165.3116 , 700– 800 m , 20 Nov. 2010 , M. Wanat & R. Ruta leg. ( MNHN ). Paratypes NEW CALEDONIA : 1 ♀ , same data as the holotype ( MNHW ); 1 ♀ , Aoupinié, -21.18151 165.30048 , 790–830 m , 27 Nov. 2010 , M. Wanat leg. ( MNHW ). Description of the holotype (³) Body thickset, moderately convex ( Fig. 1B ); LB = 2.25 mm ; maximum pronotal width at base (WP = 0.90 mm ); maximum elytral width at basal third (WE = 1.18 mm ). Dorsum blackish, non- metallic, paler on elytral disc and anterior part of pronotum. Frons and vertex finely microreticulate and finely punctate; head grooves moderately impressed, continued to postantennal region; genae and frontal carina short; antennae slightlty longer than ½ body length ( LAN = 1.35 mm ; LAN/ LB = 0.60), yellowish, gradually darker towards apex; LA: 100:77:64:64:91:82:91:91:91:91:132. Pronotum trapezoidal, distinctly transverse (LP = 0.50 mm ; WP/LP = 1.80), laterally straight; anterior angles distinctly prominent; antebasal transverse sulcus weakly impressed, weakly sinuate, without clearly distinguishable lateral fovea; pronotal surface microreticulate, opaque, with small, dense punctures, distinctly impressed. Elytra slightly elongate (LE = 1.73 mm ; WE/LE = 0.68), laterally clearly arcuate ( Fig. 6A ); punctuation slightly larger than on pronotum; surface finely microreticulate; interstriae regularly punctulate. Anterior and middle legs yellowish; hind legs brown; first pro- and mesotarsomeres moderately dilated; first metatarsomere in male distally slightly expanded on inner side; adhesive setae present on ventral side of first pro-, meso- and, partially, metatarsomeres. Venter brown; last abdominal ventrite laterally clearly incised, without special preapical impressions. Median lobe of aedeagus (LAED = 1.03 mm ; LE/LAED = 1.67) ( Fig. 8C ) in ventral view laterally parallel, slightly narrower at basal ²⁄5s and toward apex; apex flat, elongate, with rounded margin; ventral surface with shallow median groove and two thin lateral carinae; in lateral view, median lobe strongly bent at basal fourth, with sinuate apical part; dorsal ligula quite short – from apical ²⁄5s to pre-apical part of aedeagus –, thin, tapered towards apex.

Biometry Male (n = 1): LE = 1.73 mm ; WE = 1.18 mm ; LP = 0.50 mm ; WP = 0.90 mm ; LAN = 1.35 mm ; LAED = 1.03 mm ; LB = 2.25 mm ; LE/LP = 3.45; WE/WP = 1.31; WP/LP = 1.80; WE/LE = 0.68; LAN/LB = 0.60; LE/LAED = 1.67. Female (n = 2): LE = 1.95, 1.73 mm ; WE = 1.33, 1.20 mm ; LP = 0.58, 0.50 mm ; WP = 1.01, 0.89 mm ; LAN = 1.35, 1.25 mm ; LSPc = 0.16, 0.16 mm ; LB = 2.59, 2.25 mm ; LE/LP = 3.39, 3.45; WE/WP = 1.31, 1.35; WP/LP = 1.76, 1.78; WE/LE = 0.68, 0.70; LAN/LB = 0.52, 0.56; LE/LSPc = 12.50, 10.78. Paratypes (females) very similar in shape and sculpture to the holotype . Dorsum evenly black. Antennae slightly shorter. Spermatheca ( Fig. 11B ) with small, subrounded basal part; collum thickened, tapered towards apical part, elongate; ductus thin, elongate, preapically inserted on dorsal side, single-coiled. Distribution Endemic to the Aoupinié area, Central Grande Terre ( Fig. 14B ). Ecological notes No ecological notes are available for this species, but collecting localities are located in a dense, evergreen humid forest area between 700 and 830 m a.s.l. Pollen found in the gut of some specimens.
