Material examined

(7 ex.). China: 1 male (IZAS), "Yunnan, Xishuangbanna, Menglun town, W. reserve station, 2004.II.13, 720 m, Wu Jie leg". 2 females (CCCC), "Yunnan, Ruili, Bangda village, 1432 m, 2014.IX.16, night, Yang Xiaodong leg.". Myanmar: 1 male, 1 female (IZAS), "Myanmar, Kachin state, Putao distr., 5km NW. of Upper Shankhaung; rain forest; 666 m, N27.4415, E97.2584, 2016.XII.21, SHI H.L. lgt., in dead log; CAS-SEABRI exp. 2016". 1 female (IZAS), "Myanmar, Kachin state, Putao distr., way btw. Upper Shankhaung to Wasandum; rain forest; 1075 m, N27.4765, E97.2060, 2016.XII.11, SHI H.L. lgt., in dead log; CAS-SEABRI exp. 2016". Vietnam: 1 male (IZAS), "TONKIN, Hoa-Binh, leg., A de Cooman".

Diagnosis.

Medium size in the subgenus, body length 9.4-10.0 mm; dorsal surface black, elytra without metallic hue; anterior patch zigzag, five intervals wide, in the third to seventh intervals; posterior patch separate, composed of four small spots, in intervals 2-3, 4-5, 6, and 7-8 respectively. Pronotum transverse, PW/PL 1.56-1.65; lateral margins strongly sinuate before posterior angles. Elytral apex slightly curved, outer apical angles rounded; sutural angles blunt; third interval with four setigerous pores, the middle two at approximately anterior two-fifth and two-third; ninth interval with sparse fine setae. Median lobe of aedeagus strongly sinuate on ventral margin.

Comparison.

Only three species in the subgenus have four setigerous pores in the third interval of the elytra, but the other two species P. cicindeloides and P. fascinator have no yellowish patches on the elytra. This species is very similar to P. obtusipennis in elytral pattern. For more detailed comparisons between them, see remarks of the latter species (p. 38).

Supplemental description.

Male genitalia (Fig. 40). Median lobe of aedeagus fine, abruptly bent after base, forming a distinct angle on the ventral margin; ventral margin strongly sinuate near middle, dorsal margin concaved near base; apical orifice opened to the left; apical lamella small, a little flat, gradually narrowed to apex, slightly bent dorsally in lateral view; endophallus with fine scales only on basal half, without spines. Female genitalia. Internal reproductive system (Fig. 58): spermatheca pedunculate, inserted on the joint of common oviduct and bursa copulatrix; spermathecal body fusiform, apex pointed, longer than the pedicel, distinctly bent; spermathecal gland inserted on the joint of spermathecal pedicel, apex shortly dilated, approximately twice as long as spermatheca. Gonocoxite 2 of ovipositor (Fig. 47) scimitar-shaped, abruptly bent to the outer side at apical fifth; length approximately five times basal width; outer margin with three dorsolateral ensiform setae, the basal one finer than and a little distant from the other two; one doromedial ensiform seta near apex.

Distribution.

China (Yunnan), Myanmar (Mogok, Putao), India (Assam), N Vietnam. This species is sympatric with P. acutidens sp. n. in north Myanmar and Yunnan, but much rarer. (Fig. 60)
