Diagnosis

Arsipoda communis sp. nov. is a bronze, strongly metallic species quite similar in sculpture and color to A. montana sp. nov. It can be distinguishable by the less transverse pronotum and the more weakly impressed pronotal transverse sulcus ( Fig. 4B, E ). Median lobe of aedeagus is also useful to discriminate between the two species ( Figs 8D , 9C ).

Etymology

The specific epithet is a Latin adjective referring to its relatively wide distribution in New Caledonia.

Description of the holotype (³)

Body moderately elongate and convex ( Fig. 1C ); LB = 2.25 mm; maximum pronotal width at base (WP = 0.78 mm); maximum elytral width at basal third (WE = 1.06 mm). Dorsum bronze, metallic. Frons and vertex microreticulate and densely punctate; frontal grooves very weakly impressed, not continued to postantennal region; genae and frontal carina short; antennae slightly longer than ½ body length ( LAN = 1.44 mm; LAN/LB = 0.64), brownish, slightly paler basally; LA: 100:67:58:58:83:83:92:92:9 2:92:125. Pronotum trapezoidal, distinctly transverse (LP = 0.48 mm; WP/LP = 1.63), laterally straight ( Fig. 4B ); anterior angles slightly prominent; antebasal transverse sulcus thin but clearly impressed, straight; lateral fovea distinctly impressed; pronotal punctuation small and shallow, similar to head punctures, dense, evenly distributed on the densely microreticulate surface. Elytra moderately elongate (LE = 1.67 mm; WE/LE = 0.63), laterally moderately arcuate; punctuation strongly impressed, clearly larger than on pronotum; interstriae microreticulate and micropunctuate. Legs yellowish; hind femora distally darkened; first pro- and mesotarsomeres distinctly dilated; adhesive setae present on ventral side of first pro-, meso- and, partially, metatarsomeres. Venter dark brown; last abdominal ventrite laterally clearly incised, without special preapical impressions. Median lobe of aedeagus (LAED = 1.10 mm; LE/LAED = 1.52) ( Fig. 8D ) in ventral view laterally parallel, apically rounded, with a wide, rounded median tooth; ventral surface with a deep median groove with sinuate lateral margins; in lateral view median lobe strongly sinuate, with dorsally bent apical part; dorsal ligula fusiform, narrow, from half length to apical part of median lobe of aedeagus.
