Collins; Event: eventDate: 2013-11 ; Record Level: institutionCode: UFAM ; collectionCode: CTGA ; basisOfRecord: PreservedSpecimen Notes Identification to species level follows Buitrago-Suarez and Burr (2007) based on the following characters: head strongly depressed with extended cranial fontanelle; loop-like dark bars forming reticulated pattern which extends far below lateral line and connects dorsally; no clear demarcation between dark dorsal and pale ventral regions; and caudal fin with fewer than 45 spots. While we follow the taxonomy of Buitrago-Suarez and Burr (2007) , we also consider the possibility that P. reticulatum Eigenmann & Eigenmann, 1889 is a junior subjective synonym of P. fasciatum (Linnaeus, 1766) in light of the study of Carvalho-Costa et al. (2011) . These authors reported minimal genetic differentiation among the taxa considered conspecific with P. fasciatum previous to the study of Buitrago-Suarez and Burr (2007) . Four individuals were caught at night using gill nets in a lake connected to the river. An example of two live specimens is pictured in Fig. 31.
