Teleostei (teleosts) > Siluriformes (Catfishes) > Pseudopimelodidae (Bumblebee catfishes, dwarf marbled catfishes)
Etymology: Lophiosilurus: Greek, lophos = crest + Greek, silouros = cat fish (Ref. 45335).
More on author: Steindachner.

Issue
Common names according to Britski et al. (1986) and Ihering (1968). The name L. agassizi was mentioned by Steindachner to refer to L. alexandri. It is possible to conclude because he indicated the same reference of description of L. alexandri (Steindachner, Ichthyol. Beitr. V, p. 106, pl. XV). Species redescribed in Pinto & Marzulo (1975:3).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00264 - 0.01578), b=3.09 (2.88 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.6 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100).
