Description. Holotype. Body narrowly oblong. Dorsal side red brown with contrast black pattern: pronotum with two large black spots covering half of surface, elytra with black tubercles. ( Fig. 13 View FIGURES 13–18 ). Underside fulvous to brown with blackened meso- and metapleurae. Antennae and legs entirely fulvous.

Head with small eyes widely and weakly emarginate near antennal base. Labrum about 1.55 times as wide as long, anterior margin almost straight, surface shagreened with a few pale setae along anterior margin; frontoclypeus with wide triangular notch on anterior margin, indistinctly separated from frons, with rather strong and sparse punctures; frons wide, with longitudinal groove in middle; interocular space 2.4 times as wide as transverse diameter of eye; frontal tubercles indistinct; vertex densely and deeply punctured. Ocular grooves absent; frons and occiput with sparse, very short adpressed setae. Antennae filiform, reaching posterior third of elytra; proportions of segments 11-8-8- 13-12-13-13 - 13-12-12-15 (scale: 1: 0.25 mm), segments 1 and 2 slightly curved, segments 3–5 slightly thikkened apically, segments 8–10 cylindrical, 11 with pointed apex. Pronotum moderately convex, 1.28 times as wide as long, with rounded lateral and almost straight posterior and anterior margins; surface rugose, sparsely covered with thin curved setae, with a few smooth and shiny tubercles smaller in middle and larger on sides. Anterior angles obtuse, posterior angles acute, prominent, each of them with one long seta.Anterior margin unbordered, but swollen and smooth, separated from the rest of surface by large punctures; lateral and posterior margins bordered. Anterior margin of proepisterna (anterior margin of lateral arms of prosternum) straight; propleura (pronotal hypomera) distinctly punctate and pubescent. Scutellum conical with blunt apex, surface rugose and pubescent. Elytra parallel in basal two-thirds and narrowed in apical third; with developed humeral calli and indistinct basal elytral convexity; 1.4 times as long as wide; rugose but without distinct punctures, with large and small tubercles forming no ridges; large tubercles, which are high, conical and with sharp apex, clearly stand out from the rest of surface. Pygidium shagreened with narrowly rounded apical margin. Mid- and hind tibiae emarginate on outer surface near apex. Underside of all femora with very small, hardly visible tooth in apical third. Claws appendiculate; claw segment of middle and hind legs about 2 times longer than lobes of segment 3. Aedeagus parallel-sided, with narrowed apex ( Figs 39–40 View FIGURES 35–45 ); length of aedeagus 1.25 mm. Body length 4.6 mm, width 2.25 mm.

Paratypes: Body length 5.3 mm in male, 5.5 mm in female. Spermatheca C-shaped ( Fig. 45 View FIGURES 35–45 ).

Remark. We have also seen one specimen, which probably belongs to this species, collected in Yunnan, in the IOZ collection. However, it was not dissected and we do not include it in the type series.

Etymology. The new species is named after the entomologist Rostislav Filimonov (Saint Petersburg), who accompanied us during our fieldwork in Northern Vietnam in 2018.

Distribution. Northern Vietnam, China (Yunnan).

Differential diagnosis. This new species is similar to P. tuberosa in the glabrous elytra with tubercles, but differs in the pronotum with setae, coloration, and body shape (see the key below).
