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).

Morphology | Morphometrics
soft rays: 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).
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
Phylogenetic diversity index (Ref. 82805
= 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. 93245
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
