Issue
The most recent reference to distribution is by Weitzman & Weitzman (1982), but due to a printer’s error Fig. 22.10 provides the correct distribution for Nannostomus trifasciatus, not Fig. 22.11. The most recent systematic description by Weitzman (1966). Weitzman et al. (2001) most recently discussed the geographical forms of this species.including a newly discovered form from Peru called the coral red pencilfish.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00409 - 0.02444), b=3.19 (2.98 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): Unknown.
