Etymology: Photonectes: Greek, photos = light + Greek, nekton = swimmer (Ref. 45335); xenopogon: Name from Greek words 'xenos' for alien and 'pogon' for beard, referring to the barbel structure of the new species which does not resemble those of other members of subgenus Trachinostomias, but distant by other characters P. dinema.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 18; Anal soft rays: 23; Vertebrae: 59 - 62. This species is distinguished by the following characters: pectoral with one long and strong ray that consists of two tightly connected halves; uniserial praemaxillare dentition; vertebrae 59-60; postorbital organ 1.0% (immature male) or 2.4% (mature male) of SL; the chin barbel is relatively short (4.8% SL for SL 11.0 cm) with terminal bulb not protruding beyond the stem; internal pigmentation and flat non-pigmented asymmetrically bifurcated terminal filament on its tip (Ref. 125186).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00116 - 0.00786), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (11 of 100).
