Etymology: Symphurus: Greek, syn, symphysis = grown together + Greek, oura = tail (Ref. 45335);  maculopinnis: The specific name, maculopinnis, from the Latin macula, meaning spot, and pinna, meaning fin, referring to the conspicuous spots on the dorsal and anal fins of this species; noun in apposition (Ref. 87974).

Western Pacific: Tonga Arc, Volcano-19. Tunnicliffe et al., 2010 (Ref. 88005) indicated that this species was also observed at shallower depths (between 195-381 m) at a second, nearby site (Volcano-1). However, re-examination of photographs indicates that the individuals upon which these observations were based can not be positively identified. Thus, reported occurrences of S. maculopinnis both at Volcano-1 and at these shallower depths is tenuous (Ref. 87974).

簡短描述 型態特徵 | 形態測量圖

Symphurus maculopinnis is distinguished from all other species of Symphurus by the combination of a 1–2–2–2–1 ID pattern, 14 caudal-fin rays, 3+6 abdominal vertebrae, 49 total vertebrae, about 89 scales in a longitudinal row, 92 dorsal-fin rays, 77 anal-fin rays, a blunt squarish snout, blind-side lower jaw with thick lip with conspicuous plicae, and by conspicuous ocellated (sometimes partially) black spots on the posterior dorsal and anal fins (Ref. 87974).

生物學特性     字彙 (例如 epibenthic)

Known only from the holotype, collected on soft sediments at 561 m; 56 other individuals observed, but not collected, were found on a variety of substrata, including coarse gravel, gravelly sand-shell and gravelly sand, located between 433-561 m on Volcano-19, Tonga Arc, western Pacific. Considered to be a true vent species since (Ref. 87974).
