Medium size in the subgenus, body length 8.4-12.5 mm; dorsal surface black, elytra usually with faint cyan hue; anterior patch usually nearly round, three to five intervals wide; posterior patch separate, composed of three small spots, in intervals 2-3, 4-6, and 7 respectively, the middle one variable, when narrowest, present on the fifth interval only. Pronotum transverse, PW/PL 1.53-1.63; lateral margins sinuate before posterior angles, posterior angles nearly rectangular; disc with fine wrinkles. Elytra flat; apical truncation distinctly curved; outer apical angles usually acute (Figs 22, 24), sometimes obtuse (Fig. 23) or acuminate (in S. Vietnam); sutural angles blunt; third interval with three setigerous pores, the second one near middle of elytron. Median lobe of aedeagus with apical orifice large, opened to left-dorsal side (Fig. 38).
P. o. ornatus is distinguishable from similar taxa by the acute or obtuse elytral outer apical angles and elytral anterior patch usually round. P. o. ornatus is sympatric with P. obtusipennis and P. amplus in China, and all have similar elytral pattern. From the latter two species, P. ornatus can be easily distinguished by the elytral apical outer angles not rounded and without separate spot on the sixth interval.
Male genitalia (Fig. 38). Median lobe of aedeagus slender and bent; in lateral view, ventral margin evenly curved in the middle; in ventral view, right margin barely sinuate near middle, apical lamella slightly bent to the right; apical orifice larger than P. acutidens , opened to left-dorsal side; apical lamella small, side paralleled in ventral view, in lateral view gradually narrowed to apex, length a little greater than the basal width, apex rounded; endophallus with very fine scales on some regions, without spines. Female genitalia. Internal reproductive system (Fig. 51): spermatheca pedunculate, inserted on the joint of common oviduct and bursa copulatrix; spermathecal body fusiform, a little longer than the pedicel, distinctly bent; spermathecal gland inserted on the joint of spermathecal pedicel, apex dilated, much longer than spermatheca. Gonocoxite 2 of ovipositor (Fig. 48) scimitar-shaped, abruptly bent to the outer side at apical fourth; length approximately six times as basal width; outer margin with three dorsolateral ensiform setae, the basal one a little distant from the other two; inner margin with one doromedial ensiform seta near apex.
A relatively widely distributed species, known from localities east to Salween River: China: Yunnan (Xishuangbanna and Honghe Prefectures), Hainan; Myanmar (Tenasserim), Thailand, Vietnam, Laos, Cambodia (Fig. 59).
We attribute above specimens to P. ornatus based on the descriptions ( Schmidt-Göbel 1846; Andrewes 1923) and a photograph of one syntype we took in NMPC years ago (Figs 9, 16). The syntype of P. ornatus has an almost round elytral anterior patch and the outer apical angles acute, not acuminate. It is agrees perfectly with the examined materials from southeast Yunnan and Tonkin. They are quite probably the same species, although the genitalia of syntype were not studied.
The specimens from Hainan are distinctive in having a slightly different elytral pattern: anterior patch generally smaller, usually three or four intervals wide (Fig. 11); specimens from other localities (Yunnan, Tonkin, and Myanmar) have the anterior patch generally larger, usually five intervals wide (Figs 9, 10). But all examined specimens of P. ornatus ornatus have the anterior patch nearly rounded (length subequal to the width).
