Issue
The most recent reference to distribution is by Weitzman & Cobb (1975) and Weitzman & Weitzman (1982), but due to a printer’s error Fig. 22.13 provides the correct distribution for Nannostomus unifasciatus, not Fig. 22.12. This species is frequently exported as an aquarium fish from at least Peru and Guyana.
