Description
Table 1. Morphometric data of Bryconops tocantinensis. Values are given as percents of standard length and/or head length. Range includes the holotype and specimens cleared and stained (c&s) (n = number of specimens; SD = standard deviation). Interlandmarks (ILM) are equivalent to the established by Sidlauskas et al. (2006: fig. 2), except the landmark 5, which was moved to the adipose-fin terminus.
