Description (male). 7.0–8.0 mm. Dark reddish-brown, sometimes with shiny bronze coloration on elytra, mouthparts and setae yellowish brown. Dorsal side shiny and glabrous.
Head. Frons flat, clypeus feebly depressed at middle. Clypeus bidentate, lateral margins subconvex.
Pronotum. Base bilobate, straight or feebly concave at middle, straight and obliquely divergent on each side. Posterior angles obtuse. Lateral margin straight, feebly then strongly convergent anteriorly. Anterior angles feebly sharp.
Elytra. Interstriae flat, smooth, without microreticulation, with fine punctation; punctures evenly dispersed, much smaller than pronotal punctures, separated by about 1–2 times their diameter; interstriae bearing 1–2 rows of sparse, larger setae mainly near apex. Anterior margin straight, projecting obliquely from base of 5 th stria to fit the basal margin of pronotum. Side of elytra evenly curved. Setae sparse, distributed only near apex of elytra and along odd interstriae.
8 th tergite. Fine punctation evenly distributed, less dense than punctation on pronotum. Apical margin not enlarged. Furrow not deep.
Sternites. Last sternite strongly enlarged, tegument feebly microreticulate, shiny, completely covered by punctation similar to that on 8 th tergite. Other sternites normally developed, strongly microreticulate, dull, punctate only on sides.
Legs. Protarsi normal. Median tooth of outer margin of protibia closer to apical tooth. Inner margin with tooth-like lamella in front of median external tooth and feebly sinuate before apex ( Fig. 19View FIGURES 18 – 25).
Aedeagus ( Fig. 11View FIGURES 10 – 17). Left paramere evenly and feebly projected laterally in apical third. Right paramere short, even, enlarged and with small curve at apex in lateral view.
Notes. Female similar to male, with simple inner margin of protibia. 8 th tergite short, very transverse.
Distribution. This species is known only from Mt. Do, in south New Caledonia.
Etymology. This species is named after its type locality.
Remark. Paulian (1991) illustrated this species under the name P. fracticolloides .
