Comparisons. This species differs from other species of the genus by the combination of: elytra with metallic green lateral stripes, elytra disc reddish brown with metallic hue, postgenae without suborbital setae, and males with rudimentary adhesive setae on mesotarsomere 1. It is most similar to P. latecincta , with both having metallic green lateral stripes on the elytra. However, P. circumdata is readily differentiated from the latter species in having the elytra lateral stripes narrower, only extended medially to interval 7 in the middle, elytra disc with distinct metallic hue, and males with adhesive setae ventrally on mesotarsomere 1.

Description. Body length 10.0–11.0 mm. Head and pronotum dark brown, with faint metallic green hue; mouthparts yellowish brown, apices of mandibles dark brown; basal four antennomeres reddish brown, apical ones distinctly darker; elytra disc reddish brown, with distinct metallic purple hue, with narrow metallic green lateral stripes, extended medially over intervals 8 and 9 and half of interval 7 at middle, stripes narrowly continuous at base, nearly extended to sutural angles at apex, interval 1 completely brown; elytral lateral margins and epipleura brown with strong metallic hue; legs dark brown, apices of femora piceous with metallic green hue; venter dark brown. Vertex finely and densely punctate; postgenae without suborbital setae; antennae barely extended to pronotal base; labrum quadrate, apex nearly straight; mentum with a pair of minute median setae, barely visible in some specimens. Pro notum sub-cordate, PW/PL = 1.35–1.43, usually slightly wider than head, PW/HW = 0.99–1.04; widest at anterior third, strongly narrowed to base, more or less sinuate before posterior angles; posterior angles widely obtuse; disc usually with sparse punctures. Elytra slightly dilated to apex, with shallow isodiametric microsculpture; striae well incised, with fine puncture rows; intervals sparsely punctate; disc with large shallow depressions near basal third of intervals 3 to 6. Males with uniseriate adhesive setae near apex of mesotarsomere 1, with biseriate setae on apical half of mesotarsomere 2 and almost full length of mesotarsomere 3. Apex of abdominal sternite VII nearly straight in males. Median lobe of aedeagus stout (AL/AW = 3.9–4.1), right margin weakly pointed before apical lamella; apical lamella thick, ovate in dorsal view, LL subequal to LW, not declined to left; subuliform in lateral view, apex not bent upward. Endophallus with very large flared basal expansion of primary sclerite; flagellum extending almost to the base of apical orifice; apical sclerite narrowly V-shaped, weakly defined, basal core indistinct; basal sheath coarsely scaled, apical sheath finely scaled, similar size as basal sheath; squamate sac well divided, near middle of median lobe, dorsal-right to squamate sheath; distal sac smaller and closer to apex than proximal sac. Gonocoxite II of ovipositor nearly trapezoid, slightly longer than width, apex curved, angulate near inner apical angle, with two ensiform setae on outer apical angle, three on inner apical angle, one of them slightly distant from other two.
