Comparisons. This species is most similar to P. bicolor , distinguished as follows: (1) elytra with a median red patch of one to four intervals width, versus elytra entirely metallic in P. bicolor ; (2) right margin of median lobe distinctly sinuate before the apex ( Fig. 52 ), versus only very weakly sinuate in P. bicolor ( Fig. 51 ); (3) P. ribripicta occurs on the Asian mainland and P. bicolor is known only from the Malay Archipelago. P. rubripicta may be also confused with some species in the P. latecincta group based on a similar appearance, but it is readily distinguished from them by the presence of suborbital setae.

Description. Body length 7.1–8.8 mm. Head and pronotum reddish yellow to dark brown; antennae completely reddish brown or apical seven antennomeres slightly darker than basal ones; elytra metallic green, copperish green in some specimens, with a median red patch of one to four intervals width, with the patch edge not distinctly defined; epipleura reddish brown; venter of head and prothorax same as dorsum, venter of mesothorax, metathorax and abdomen red to dark reddish brown; legs reddish brown, femoral apices darker in some specimens. Postgenae with a pair of suborbital setae; antennae barely extended pronotum base; labrum quadrate, apex very weakly protruded at middle; mentum with a pair of short median setae. Pronotum nearly cordate, PW/PL = 1.28–1.40, nearly same width as head, PW/HW = 0.99–1.04; widest at anterior third, slightly rounded at anterior half, and then distinctly sinuate before posterior angles; posterior angles widely obtuse. Elytra slightly dilated to apex, surface without or with very faint isodiametric microsculpture; striae very shallowly incised, with fine puncture rows; intervals weakly convex, very sparsely punctate; disc with large shallow depressions near basal third of intervals 3 to 6. Males with biseriate adhesive setae on apical half of mesotarsomere 1, and most of length of mesotarsomeres 2 and 3. Apex of abdominal sternite VII weakly emarginate in males. Median lobe of aedeagus slightly slender, gradually narrowed to apex, ventral margin nearly straight; right margin distinctly sinuate before apex in dorsal view; apical lamella wide and short, apex rounded, weakly bent upward in lateral view; endophallus identical to that of P. bicolor . Gonocoxite II of ovipositor nearly quadrate, same length as basal width, apex strongly concave, with three ensiform setae on inner apical angle, and two on outer apical angle.

Distribution ( Map 9 , green). India, Nepal, Vietnam, Myanmar, Thailand, China (Xizang, Yunnan, Guangxi).

Remarks. This species differs from P. bicolor only in the color of elytra and subtle differences in the apex of male genitalia. Considering their allopatric distributions and stable differences, we treat them as distinct species.
