Diagnosis. Among all species of Phanolinopsis , P. metaksenios can be identified based on the following characteristics: large size (11.0– 15.5mm); disc of pronotum with four punctures at the center of the pronotum, each one delimiting the corner of a square (few specimens with five punctures); coloration of head and pronotum not red; posterolateral corners of head not extremely pointed; aedeagus as in Figs. 37–39 . Phanolinopsis metaksenios is sympatric with P. discedens through much of their range, but these two species can be distinguished from each other based on their coloration (pronotum and elytra different color in P. discedens ( Fig. 1 ); similar color in P. metaksenios ( Fig. 5 )); the distance between the eye and the postmandibular ridge in lateral view (short in P. discedens ( Fig. 13 ); long in P. metaksenios ( Fig. 17 )) and the shape of the aedeagus (tip of median lobe pointed and apex of paramere narrow in P. discedens ( Figs. 25–27 ); tip of median lobe wider and rounded and apex of paramere wide in P. metaksenios ( Figs. 37–39 )).

Description. Body length 11.0– 15.5mm. Head and pronotum metallic green-blue; elytra dark metallic blue with purple overtones. Mouthparts, antennae, mesoscutellum, ventral surface of thorax and legs brown and most of abdomen brown. Abdominal segment VII with variable coloration, either completely dark orange or brown with posterior 1/3 orange; segment VIII orange. Head transverse, width: length ratio = 1.44. Epicranium with transverse and polygon-shaped microsculpture and sparse micropunctures; with large to medium-sized punctures around margin of head (becoming more numerous near posterior margin); with numerous medium-sized punctures in 3–4 rows from lateral margins to center; center of epicranium impunctate. Eyes large, length of eyes / length of head ratio = 0.59, distance between eyes as wide as 1.65 times length of eye. Area between postmandibular ridge and eye (lateral side of head) wide, with polygon-shaped microsculpture; posterolateral corner of head not pointed. Antennomeres 1–9, 11 longer than wide; antennomere 10 subquadrate. Neck with micropunctures, microsculpture, and with sparse small punctures. Pronotum slightly longer than wide, width: length ratio = 0.88; surface of pronotum uniformly covered with sparse micropunctures and dense rectangular-shaped microsculpture; appearing matte due to microsculpture. Pronotum with few large punctures around margin; disc of pronotum with four large punctures at center, each one delimiting corner of square; few specimens with five punctures. Elytra with mediumsized punctures (about 10–11 punctures / elytron width); distance between punctures from confluent to 0.5 times width of puncture. Elytra appearing shiny; with sparse longitudinal and polygon-shaped microsculpture. Abdominal terga with 2–3 rows of small punctures. Male secondary sexual structures with sternum VIII having shallow emargination medially; sternum IX with deep U-shaped emargination medially. Female without obvious sexual structures. Aedeagus as in Figs. 37–39 ; in dorsal view paramere converging to rounded tip; paramere slightly shorter and narrower than median lobe; in lateral view paramere slightly concave apically; paramere with peg setae as in Fig. 39 . Median lobe in dorsal view wide, converging to rounded apex, with two broad teeth apically; in lateral view becoming narrow and elongate near apex.

Distribution. Known from the provinces of Heredia and Puntarenas in Costa Rica and the province of Chiriquí in Panama.

Habitat. Collected with flight intercept traps, malaise traps and in leaf litter at elevations between 100–1600m at lowland and cloud rainforests.

Etymology. The specific epithet is derived from the Greek word µετάξι (silk) and refers to the silky appearance of the head and pronotum. The epithet is treated as a noun in apposition.
