MATERIAL. Holotype ♂ ( ZMMU) and two paratypes, ♂, ♀ ( SIEE) with label: ‘N-Vietnam, 40 km WNW of/ Lao Cai, env. Y Ty, Bat Xat / Nat[io]n.[al] Park, h= 1600-1900 m / 22°37´-37.6´N/ 103°37.3´-38.3´E, 16-21./ leg. D. Fedorenko X.2018 ’.

Genitalia examined in all the specimens.

DIAGNOSIS. No significant differences from P. glabellus sp.n. other than the elytron with middle discal seta, d2, fe 3 not sexually dimorphic, and aedeagus is distinctive.

DESCRIPTION. Body as in Fig. 2 . BL 8.4–8.8 mm. Pronotal base nearly straight, two fifths wider than apex. Elytral stria 7 inside humeral angle; parascutellar striole entire, stria 1 adjoining basal ridge. D2/EL 0.50–0.57 (0.55, n = 3×2). USS: 13–15.

Aedeagus ( Figs 14–15 , 23, 31 ): median lobe in lateral view geniculate, apex in ventral view lamellate, triangular. Right paramere oval.

Abdominal urites VIII and IX, with reproductive tract, in female as in Figs 56–57 and 68 .

DISTRIBUTION. Only known from the type locality which is on the Hoang Lien [Son] mountain ridge 33 km distant from that of P. glabellus sp.n.

NAME. Refers to the elytron with single discal seta.

HABITATS AND HABITS. All the specimens were hand collected in a cloudy forest.
