Etymology: Stiphodon: Greek, stiphos, -eos, -oys = mass + Greek, odous = teeth (Ref. 45335); julieni: Technically, the name is based on "two Juliens" and should be emended to julienorum (Ref. 46206).
Eponymy: Julien Marquet (along with Julien Keith – see preceding entry) made an extensive collection of fish in French Polynesia (particularly in the Austral Islands). [...] (Ref. 128868), visit book page.

Dorsale stekels (totaal) : 7; Dorsale zachte stralen (totaal) : 8 - 9; Anale stekels: 1; Anale zachte stralen: 10. Distinguished by the following characters: predorsal midline with 10-14 cycloid scales; belly with cycloid scales close to anus; lateral scales 31-36 reaching upper pectoral base; transverse series back 8-9; transverse series forward 9-12; upper jaw with 33-38 tricuspid teeth; modally 35-36; head and body ventrally dusky in males, mostly immaculate in females; pelvic disk dusky in males with dusky blotches medially; females pelvic disk generally without pigmentation (Ref. 46975).
Body shape (shape guide): elongated.
Collected in a clear, relatively swift rainforest stream, close to the coast. Sexual dimorphism well developed: sexual dichromatic color patterns well developed in both sexes; males with longer unpaired fins (Ref. 46975).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.

Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
