Species of Hypancistrus are best distinguished from each other by their color pattern and cannot be separated by traditional morphometrics used in loricariids (Armbruster et al. 2007). Numerous undescribed forms remain, and there is considerable variation in color patterns (Armbruster et al. 2007). Undescribed forms of Hypancistrus (and other loricariids) are assigned L-numbers by the aquarium fish magazine DATZ that are widely used by aquarists, and some of these forms are discussed. Here we describe two new species of Hypancistrus with spotted color patterns.
