Bates, 1890: 212 (‘Wa-shan’, Sichuan); Bousquet, 2003: 516; 2017: 748. — pratti: Tschitschérine, 1898: 173; Csiki, 1930: 670; Jedlička, 1962: 296; Lorenz, 1998: 266; 2005: 287; Sciaky, Allegro, 2013: 114.

MATERIAL. ♂ ( ZIN) labelled: ‘ MUSEUM PARIS, MOU- PIN, A. DAVID 1870 ’ and ‘ Pratti, H.W. Bates, Tschitscherin det’, and two ♀♀ ( SIEE) labelled: NE Chongquing, 50 km N of Chengkou, h= 1500-2000 m, 30.VI-5.VII.1995, leg. A. Shamaev.

Aedeagus examined in the male, genitalia and reproductive tract examined in a female.

DIAGNOSIS. Different from P. matalini sp.n. chiefly in the following characters. BL 22–26 mm. Body as in Fig. 5 . Microsculpture distinct, isodiametric on elytra, including reflexed lateral margin. Pronotum broadest slightly before middle, PLw/PL 0.43–0.45 (0.44, n=3), with inner basolateral sulci slightly deeper and barely longer, reaching basal margin; outer sulci shorter, 1/3–1/2 as long; base impunctate. Median line obliterate basally and apically. Elytral striae deep, impunctate; parascutellar striole missing or very short. Intervals convex or very so, those 3 and 7 confluent apically, 7 and 8 subcarinate apically and 8 also basally. Discal seta d3 adjoining stria 2, D3/EL 0.24–0.29 (0.26, n = 3×2). Stria 7 bi- or trisetose at apex. USS: 32–39. Prosternal process flat, with apex truncate, in lateral view rectangular, with apex blunt; inclination with apex truncate and often vaguely beaded, in lateral view rectangular or slightly obtuse, with apex not or barely blunted and declivity more or less straight; this declivity in caudal view slightly concave, with sides finely beaded. Mesepisterna, metepisterna, sides of metaventrite and abdominal sternites II–III finely and densely punctate. Apical 5/6 abdominal sternite VII in male with a high, triangular, median carina reaching apex ( Fig. 14 ). Legs: ti 1 with single postero-apical spinule; ti 3 with 2–4 outer setae; meso- and metatarsomeres 1–3 with dorso-apical setae.

Aedeagus ( Figs 19–20, 25 , 35): apical 3/5 median lobe in lateral view bent ventrad at an acute angle; apex in dorsal view subtriangular.

DISTRIBUTION. Southern China: Sichuan , Chongquing, Yunnan, Fujian, Gansu, Guizhou.

HABITATS AND HABITS. No exact data other than this species occurs at 300– 1.800 m altitudes [ Sciaky, Allegro, 2013].
