Etymology: Priapichthys: Taken from Priapus, the Greek, and Roman god of procreation in the mithology and also = a phallus; diminutive + Greek, ichthys = fish (Ref. 45335); puetzi: Named in honor of the collector Mr. W. Pütz, Würselen, Germany (Ref. 42984).
Eponymy: This is not a true eponym as it is after Priapus, the Greek god of fertility. [...] Wilfried Pütz (d: 1940) of Würselen, Germany, is an aquarist. He collected in the field with the junior author, Vollrad Etzel. (Ref. 128868), visit book page.

背棘 (总数) : 0; 背的软条 (总数) : 9 - 10; 臀棘: 0; 臀鳍软条: 9 - 10; 脊椎骨: 26 - 27. The species lacks a series of vertical stripes along its body sides; males with a large black spot near the base of the gonopodium. Lower pharyngeal bone with a total number of 150 teeth (mean value); conical teeth of ceratobranchial 4, concentrated near the medial region and not extending at the side-arms. The scissor-like shaped gonopodium tip is rounded and strongly curved downward; ray 3 with strongly reduced spines; knob-like wings present dorsally on gonactinosts 5 and 6 of the gonopodial suspensorium (Ref. 42984).
