Diagnosis. This species can be easily distinguished from all other taxa of Phanolinopsis   based on the morphology of the head. In P. goniakos   the posterolateral corners of the head are pointed ( Figs. 4 View FIGURES 3 – 4 , 10 View FIGURES 7 – 12 , 16 View FIGURES 13 – 18 ) more so than any other known species.

Description. Body length 10.5–13.0mm. Head and pronotum metallic brown, sometimes with green overtones; elytra dark metallic brown-green. Mouthparts, mesoscutellum, ventral surface of thorax and legs brown. Antennomeres 1–6 brown; antennomeres 7–11 dark yellow. Abdominal terga and sterna brown; posterior 1/5 of segment VII and segment VIII orange. Head transverse, width: length ratio = 1.45. 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 3–4 other large puncture near center but with no other punctures on epicranium. Eyes medium-sized, length of eyes / length of head ratio = 0.48, distance between eyes as wide as 2.07 times length of eye. Area between postmandibular ridge and eye (lateral side of head) wide, with polygon-shaped microsculpture; posterolateral corner of head 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 = 0.98; 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. Elytra with medium-sized punctures (about 8–9 punctures / elytron width); distance between punctures 0.5–1 width of puncture. 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. 34–36 View FIGURES 34 – 36 ; in dorsal view paramere converging to rounded tip; paramere about as long as and narrower than median lobe; in lateral view paramere slightly concave apically; paramere with peg setae as in Fig. 36 View FIGURES 34 – 36 . Median lobe in dorsal view wide, converging to rounded apex, with two broad teeth apically; in lateral view becoming narrower near apex.

Distribution. Known from the provinces of Guanacaste and Puntarenas in Costa Rica.

Habitat. Collected with pitfall traps, flight intercept traps and in leaf litter in cloud forests at elevations between 1520–1690m.

Etymology. The specific epithet is derived from the Greek word γωνία (angle) and refers to the sharp angle of the posterolateral corners of the head. The epithet is treated as a noun in apposition.
