Diagnosis. Photinopygus chapareanus belongs in the narrow pronotum species group. Among species of that group, that have pronotum with sparse punctation (i.e., with 3–5 loosely organized rows of punctures on each half beside median impunctate line), and antennomeres 4–5 longer than wide, P. chapareanus can be recognized by the following combination of characters: tip of paramere in dorsal view rounded ( Fig. 53 View FIGURES 52–55 ), median lobe in dorsal (slightly oblique; Fig. 55 View FIGURES 52–55 ) view converging to hook-like structure, tip of hook-like structure barely divided into two tightly jointed apical peaks, and median lobe in lateral view with two large lateral teeth.

Description. Forebody ( Fig. 48 View FIGURES 48–51 ) length 4.7–5.8 mm. Color of head, pronotum and mesoscutellum dark brown to black; antennomeres 1–4 dark orange; antennomeres 5–11 dark brown to black; legs dark brown to black except prolegs dark orange in some specimens; elytra metallic blue with green or purple overtones; abdomen dark brown to black except segments 7–8 (orange). Antenna ( Fig. 51 View FIGURES 48–51 ) with antennomere 3 without tomentose pubescence; antennomere 4 with tomentose pubescence; antennomeres 4–5 longer than wide; antennomeres 6–7 subquadrate; antennomeres 8–10 transverse. Head transverse; HW/HL ratio = 1.42–1.46. Posterior margin of head slightly extended posteriad on each side of neck. Head with sparse medium-sized punctures, distance between punctures as wide as 2–3 punctures but punctures denser posteriorly. Left mandible with bicuspid tooth. Pronotum ( Fig. 50 View FIGURES 48–51 ) subquadrate; PW/PL ratio = 1.00–1.07. Lateral margins of pronotum in dorsal view posteriad of midpoint strongly converging; pronotum with 3–4 sparse rows of punctures on each half beside median impunctate line; distance between punctures as wide as 1–2 punctures but areas of pronotum without punctures. EL/PL ratio = 1.32–1.33. Elytra with dense punctation; distance between punctures as wide as 0.5–1 punctures. Metepisternum covered with punctures (impunctate area less than 1/3). Abdomen with tergites 3–4 setose; tergites 3–5 with curved carina (arch-like). In males, sternite 7 without porose structure, sternite 7 with shallow and broad emargination posteriorly; sternite 8 with small V-shaped emargination posteriorly ( Fig. 49 View FIGURES 48–51 ). Aedeagus as in Figs. 52–55 View FIGURES 52–55 ; in dorsal view paramere almost parallel-sided, slightly expanding just before apex; with broad rounded apex; paramere as long and as wide as median lobe; in lateral view paramere becoming narrower near tip; paramere with peg setae in lateral rows as in Fig. 54 View FIGURES 52–55 . Median lobe in dorsal (slightly oblique; Fig. 55 View FIGURES 52–55 ) view converging to hook-like structure, tip of hook-like structure barely divided into two tightly jointed apical peaks; in lateral view hook-like structure with two large lateral teeth.

Distribution. Known from the South Brazilian biogeographic dominion. Distributed in the states of Pará, Mato Grosso and Rondônia in Brazil, the departments of Beni, Cochabamba, and Santa Cruz in Bolivia, and the departments of Huánuco and Cusco in Peru. Map is shown in Fig. 39 View FIGURE 39 .

Habitat. Collected at low to mid (300–1040 m) elevations on vegetation, by pyrethrum fogging, and with banana and flight intercept traps.
