Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 2; Raggi dorsali molli (totale) : 27; Raggi anali molli: 17; Vertebre: 37. This species of the unspotted P. albipinna species group is distinguished by the following set of characters: long mental barbel, about 15-20% SL without terminal expansion (vs. short and blunt in P. immaculata, with terminal expansions in albipinna and dewitti); shallow head and slender trunk with a slight taper to caudal peduncle (vs. deeper heads and more abruptly tapered bodies for the 3 former species); middle lateral line pores 8-13 (vs. indistinct in albipinna, 12-29 with most 16-29 in immaculata and 17-19 in dewitti) ; divergence in mitochondrial ND2 gene between stewarti and immaculata not available from albipinna and dewitti (Ref. 84672).
Collected by bottom longline (Ref. 84672).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00247 - 0.01065), b=3.13 (2.95 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low vulnerability (20 of 100).
