Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 1; Dorsale zachte stralen (totaal): 7; Anale zachte stralen: 6. Diagnosed from all other species of the genus Pareiorhaphis by having a longer snout (71.1-75.6 vs. 52.8-69.9% HL). Can be differentiated further from most other congeners, except for Pareiorhaphis garbei, Pareiorhaphis vestigipinnis, Pareiorhaphis cerosus, and Pareiorhaphis splendens, by having smaller orbital diameter (8.6-11.3 vs. 11.7-18.8% HL). Differs further from Pareiorhaphis garbei by having bifid teeth, with a small lateral cusp in both dentary and premaxilla (vs. simple teeth, without lateral cusp in both dentary and premaxilla); from Pareiorhaphis vestigipinnis by having an adipose fin (vs. adipose fin absent); from Pareiorhaphis cerosus by having one to three preadipose azygous plates (vs. three to five plates); and from Pareiorhaphis splendens by the longer pelvic-fin spine (19.4-23.4 vs. 12.6-19.1% SL) (Ref. 75793).

Biologie     Verklarende woordenlijst (b.v. epibenthic)

The type locality is a small, shallow river with very clear, transparent water, slow to moderate current, and with bottom consisting of rocks, loose stones and sometimes gravel (Ref. 75793). Collected in areas of rapids among loose stones and pebbles. Nuptial males and larger individuals occur among larger stones and on the stronger current (Ref. 75793).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00264 - 0.01440), b=3.11 (2.91 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden ().
Kwetsbaarheid (Ref. 59153):  Low vulnerability (10 of 100) .
