Etymology: Trachinocephalus: Greek, trachys, -eia, -ys = rough + Greek, kephale = head (Ref. 45335); gauguini: Named for the French painter Paul Gauguin (1848-1903), who died in the Marquesas Islands on 8 May 1903.
Eponymy: Paul Gauguin (1848–1903) was a French artist, largely unappreciated until after his death. [...] (Ref. 128868), visit book page.

簡短描述
檢索表 | 型態特徵 | 形態測量圖
This species is distinguished from its congeners by the following characters: length of snout (SLn) 6,7-10.0% head length (HL), mean 7.8 (vs mean 12.3% in T. trachinus; 12.1% in T. myops); body depth SLn 12.6-18.9%, mean 14.7% (vs. mean 21.2% in trachinus; 21.6% in myops); eye diameter SLn 31.6-51.7%, mean 40.1% (vs. 74.8% in trachinus; 79.1% in myops); interorbital width 4·0-6·7%, mean 5·6% HL (vs. mean 8·7% in trachinus; 8·9% in myops); anal-fin rays 14-16, mode 14 (vs. mode 16 in trachinus; 15 in myops); pectoral-fin rays 11-12, mode 11 (vs. mode 12 in the two species); lateral-line scales 56-59, mode 56 (vs. mode 57 in myops); further differs from trachinus and myops by deep mitochondrial distances (15.7-19.0 and 16.9-17.6%, respectively) (Ref. 110386).
Body shape (shape guide): elongated; Cross section: oval.
