Collins ; Event: eventDate: 2013-11 ; Record Level: institutionCode: INPA ; basisOfRecord: PreservedSpecimen Notes Identification to species level for this specimen could not be adequately made using morphological characters due to the small size of the immature specimen. However, rather than exclude the individual, we compared the DNA barcodes to the COI sequences presented by Arce et al. (2013) in their doradid phylogeny. The specimen clustered with, and was 1.36% divergent from (seven mutations in 516 bp), Scorpiodoras heckelii (GenBank KC555695), and is most likely conspecific given the known distribution of the species and its congeners ( Sousa and Birindelli 2011 ). One individual was caught by hand-net on the Rio Paratucu (sampling site NH10). This specimen is pictured in Fig. 10.
