Issue
The most recent reference to distribution is by Weitzman & Weitzman (1982), but due to a printer’s error Fig. 22.12 provides the correct distribution for Nannostomus eques, not Fig. 22.13. The most recent systematic description by Weitzman (1966). This species is commonly exported as an aquarium fish from Brazil, Peru and Guyana. Most recent systematic description is by Weitzman (1966). Commonly exported as an aquarium fish since 1910, Stansch (1914).
