Type material. Holotype, female, on paper card mount in Sharp’s handwriting: “♀ Phanolinus discedens , Type, D. S.” / “Type” / “Bugaba, Panama. Champion.” / “B.C.A. Col. I. 2. Phanolinus discedens, Sharp ” / “ Sharp Coll. 1905-313.” / “HOLOTYPE Phanolinus discedens Sharp, 1884 det. R.G. Booth 2011”. In the collection of BMNH. Sharp (1884) mentioned that he had a single female specimen, which is the holotype.

Diagnosis. Among all species of Phanolinopsis , P. discedens can be diagnosed based on the following characteristics: medium size (9.5–13.2mm); disc of pronotum with four punctures at the center of the pronotum, each one delimiting the corner of a square (few specimens with less punctures); coloration of head and pronotum not red; posterolateral corners of head not extremely pointed; aedeagus as in Figs. 25–27 View FIGURES 25 – 27 . 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 View FIGURES 1 – 2 ); similar color in P. metaksenios ( Fig. 5 View FIGURES 5 – 6 )); the distance between the eye and the postmandibular ridge in lateral view (short in P. discedens ( Fig. 13 View FIGURES 13 – 18 ); long in P. metaksenios ( Fig. 17 View FIGURES 13 – 18 )), and the shape of the aedeagus (tip of median lobe pointed and apex of paramere narrow in P. discedens ( Figs. 25–27 View FIGURES 25 – 27 ); tip of median lobe wider and rounded and apex of paramere wide in P. metaksenios ( Figs. 37–39 View FIGURES 37 – 39 )).

Description. Body length 9.5–13.2mm. Head and pronotum metallic green-brown; elytra dark metallic bluegreen. Mouthparts, antennae, mesoscutellum, ventral surface of thorax and legs reddish brown. Abdominal terga and sterna reddish brown but with darker areas medially; posterior half of terga slightly lighter color; posterior 1/5 of segment VII and segment VIII orange. Head transverse, width: length ratio = 1.47. 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), but with no other punctures on epicranium. Eyes large, length of eyes / length of head ratio = 0.66, distance between eyes as wide as 1.44 times length of eye. Area between postmandibular ridge and eye (lateral side of head) narrow, 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 subquadrate, width: length ratio = 0.95; surface of pronotum uniformly covered with sparse micropunctures and dense polygon-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, but some specimens with three or fewer punctures (at least one puncture present). Elytra with large uniform punctures (about 10 punctures / elytron width); punctures almost confluent. Elytra appearing shiny; with sparse longitudinal microsculpture. Abdominal terga sparsely punctate with small to medium-sized 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. 25–27 View FIGURES 25 – 27 ; in dorsal view paramere converging to rounded tip; paramere shorter and narrower (apically) than median lobe; in lateral view paramere straight, narrower apically; paramere with peg setae along the lateral margins from tip to middle. Median lobe in dorsal view wide, converging to pointed apex, with two broad teeth apically; in lateral view becoming much narrower near apex.

Distribution. Known from the province of Puntarenas in Costa Rica and the provinces of Bocas del Toro and Chiriquí in Panama.

Habitat. Collected with flight intercept traps, pitfall traps and in leaf litter from cloud forests between 1150– 1780m.

Remarks. An additional specimen from FMNH can be tentatively included here. The specimen was labeled as “ Trigonopselaphus assmanni” by Bierig as a manuscript type from San Isidro del Cotou, Costa Rica. However, I hesitate to include it above with the other “additional specimens” since the specimen is in bad condition and it is hard to see all the characters.
