Description: Body length 5.7–6.0 mm (M = 5.8 mm, HT = 6.0 mm), forebody length 3.0– 3.1 mm (M = 3.1 mm, HT = 3.0 mm). Dark brown, abdomen reddish brown, mouthparts and antennomeres dark reddish brown, legs reddish yellow (Fig. 38).

Head (Fig. 39) moderately convex, about 1.1 times as long as wide (L/W = 1.10–1.14, M = 1.12, HT = 1.11). Surface between eyes with coarse and dense umbilicate punctures, centre of disc with punctation markedly sparser and finer and here and there with interstices larger than diameter of punctures. Eyes small, temples on average about 1.7 times as long as eyes (R = 1.48–1.84, M = 1.69, HT = 1.48). Temples markedly roundly narrowed posteriorly. Antennae long and slender, fifth antennomere more than one and half as long as wide (L/W = 1.64–1.88, M = 1.77, HT = 1.88), tenth antennomere about as long as wide (L/W = 0.93–1.07, M = 0.98, HT = 1.07).

Pronotum (Fig. 39) egg-shaped, moderately convex, with shallow basal impressions, about 1.1 times as long as wide (L/W = 1.15–1.17, M = 1.16, HT = 1.15) and slightly narrower than head (PW/HW = 0.96). Sides slightly roundly widened posteriorly. Surface with moderately coarse and sparse punctures and with distinct interstices between punctures, punctation coarse and less dense than that on head and less dense along moderately narrow unpunctured midline; midline in anterior part of pronotum more than one puncture wide.

Elytra (Fig. 39) elongate with rounded sides and distinct depression along suture in first quarter behind scutellum, slightly flattened along suture, about 1.1 times longer than wide (R = 1.13–1.14, M = 1.14, HT = 1.13). Surface moderately coarsely and densely punctured. Interstices mostly slightly larger than diameter of punctures, surface shining, without microsculpture.

Abdomen (Fig. 38) slightly widened to segment V, finely and sparsely punctured. Interstices shining, without microsculpture. Tergite VII with distinct membranous fringe apically.

Male. Posterior margin of sternite VII with short and wide triangular emargination (Fig. 43), sternite VIII with short and moderately wide triangular emargination in posterior tenth (Fig. 44). Aedeagus (Figs. 40–42) moderately long and slender, about 0.7 mm long (AL = 0.69 mm). Median lobe in ventral view with moderately wide middle part, narrowed before slightly widened apical part.

Female. Sternite VIII largely rounded posteriorly.

Differential diagnosis. The new species is arranged in a group of species with normally (depressed) punctured elytra, impunctate or sparsely punctate disc of the head and integument of tergites smooth between punctures together with P. hova Lecoq, 2008, P. minima Lecoq, 2008, and P. tanala Janák & Baňař, sp. nov. and differs from all these species by combination of fine and sparse punctation of tergites and head markedly narrowed behind eyes and in males also by very distinct shape of sternites VII and VIII.

Etymology. The name is related to the type locality.

Distribution. Paulianidia vohimana Janák & Baňař, sp. nov. is currently recorded only from the Experimental Reserve Vohimana in the central part of Madagascar (Fig. 121).

Bionomics. The type series was sifted from forest litter.
