Diagnosis. Photinopygus thafmasios belongs in the mirabilis species group. Photinopygus mirabilis and P. thafmasios can be distinguished from all other species in Photinopygus by the presence of rainbow-like coloration on elytra (Figs. 169, 220). Photinopygus thafmasios differs from P. mirabilis in the following characters: pronotum color (Fig. 222) black (reddish-brown in P. mirabilis; Fig. 171), in lateral view, median lobe (Fig. 224) wider apically than in P. mirabilis (Fig. 173), subapical tooth on medial lobe more pronounced than in P. mirabilis, and endophallus with two lobes (Fig. 225) (single lobe in P. mirabilis; Fig. 174).
Description. Forebody (Fig. 220) length 6.0– 6.6 mm. Color of head, pronotum and mesoscutellum dark brown to black; antennomeres 1–5 dark brown to black; 6–11 yellow to orange; legs dark brown to black except protarsi dark orange; elytra with diffraction gratings, almost rainbow-like coloration but color varies with angle of viewing; abdomen dark brown to black except segment 7 with anterior 3/4 dark brown to black and posterior 1/4 orange; abdominal segment 8 orange. Antenna (Fig. 223) with antennomeres 3 without tomentose pubescence, antennomere 4 with faint tomentose pubescence; antennomeres 4–6 longer than wide; antennomere 7 subquadrate; antennomeres 8–10 transverse. Head transverse; HW/HL ratio = 1.20–1.31. Posterior margin of head not extended posteriad on each side of neck. Head with sparse medium-sized punctures, distance between punctures as wide as 1–2 punctures but punctures denser posteriorly. Left mandible with bicuspid tooth. Pronotum (Fig. 222) subquadrate; PW/PL ratio = 0.94–0.95. Lateral margins of pronotum in dorsal view posteriad of midpoint concave; pronotum with 4–5 sparse rows of punctures on each half beside median impunctate line; distance between punctures as wide as 2–3 punctures but areas of pronotum without punctures. EL/PL ratio = 1.50–1.53. Elytra with sparse punctation; distance between punctures as wide as 1–2 punctures. Metepisternum with dorsal 1/3 without punctures throughout its length.Abdomen with tergites 3–4 glabrous (except line of punctures on posterior margin); 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 medium V-shaped emargination posteriorly (Fig. 221). Aedeagus as in Figs. 224–226; in dorsal view paramere narrow, converging to rounded apex; paramere subequal and slightly narrower (except apically) than median lobe; in lateral view paramere almost parallel-sided; paramere with peg setae in median rows as in Fig. 226. Median lobe in dorsal view converging to narrow pointed tip; in lateral view median lobe becoming narrower; median lobe with small subapical tooth. Endophallus with two lobes.
Distribution. Known from the Pacific biogeographic dominion. Distributed in the department of Nariño in Colombia and the province of Pichincha in Ecuador. Map is shown in Fig. 176.
Etymology. The specific epithet is derived from the Greek word θαυμάσιος (wonderful, admirable).
Habitat. Collected at mid elevations (1460–1855 m) with flight intercept and malaise traps.
