Diagnosis.

Elytral intervals 3 and 5 each with ≥ 3 large foveate discal pores, interval 7 without discal pore. Antennomere 3 without accessory setae. Pronotum subcordate, lateral margins strongly sinuate before posterior angles, posterior angles slightly dentate (Fig. 11 View Figures 7–12 ); pronotal disc without or with very faint transverse wrinkles; lateral margins with 2-4 mid-lateral setae. Male sternite VII with a small but distinct tubercle (Fig. 37 View Figures 34–39 ). Apical lamella of aedeagus relatively slender, LL/LW = 1.8-2.0 (Fig. 17 View Figures 13–18 ), apex rounded-truncated; endophallus with U-shaped bsp (Fig. 23 View Figures 19–24 ).

Comparison.

In many aspects of morphology, P. condylus sp. nov. is most similar to P. liyuani sp. nov. The comparisons between these two species provided under P. liyuani sp. nov.

Description.

BL = 15.0-15.5 mm, BW = 5.2-5.5 mm, dorsal surface and appendages black. Antennomere 3 without accessory setae, only with primary setae forming apical ring. Pronotum subcordate, PW/PL = 1.35-1.39, widest near anterior 1/3; anterior margin slightly wider than posterior margin; moderately narrowed to base (PBW/PW = 0.69-0.73); lateral margins slightly arched from anterior angles to middle, and then strongly sinuate before posterior angles; posterior angles usually acute, slightly dentate and projected outward; lateral margins with 2-4 mid-lateral setae near maximum width; basal foveae deep and impunctate, inner and outer grooves nearly straight, outer groove distinctly shorter than 1/2 length of inner one (Fig. 11 View Figures 7–12 ); disc without or with very faint transverse wrinkles aside median line. Elytra oblong; parascutellar pore absent; intervals 3 and 5 each with ≥ 3 foveate discal pores; interval 7 without discal pore. Male sternite VII with a tubercle on middle, small but well-defined (Fig. 37 View Figures 34–39 ). Median lobe of aedeagus stout, strongly curved near basal 1/3; apical lamella gradually deflected ventrally; apical lamella slightly twisted longitudinally, relatively slender (LL/LW = 1.8-2.0), a little narrowed on basal 1/3 and gently bent leftward, apex rounded-truncated (Fig. 17 View Figures 13–18 ). Endophallus long, straightly directed ventrally, gonopore opened to ventral-basal direction of aedeagus; vb quite small with rounded apex; bsp deeply grooved, U-shaped, left branch crenulate on dorsal margin (Figs 23 View Figures 19–24 , 27 View Figures 25–30 ).

Distribution.

This species is known from two localities in Mianning and Xide counties, Liangshan Yi Autonomous Prefecture (Fig. 42 View Figure 42 ).

Etymology.

The scientific name of the new species comes from a Greek root condyl - meaning lumps, referring to the well-defined tubercle on the male sternite VII of the new species.
