Collins; Event: eventDate: 2013-11; Record Level: institutionCode: UFAM; collectionCode: CTGA; basisOfRecord: PreservedSpecimen  Notes Identification to species level follows  Buitrago-Suarezand 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-Suarezand Burr (2007), we also consider the possibility that P. reticulatumEigenmann & 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. fasciatumprevious to the study of  Buitrago-Suarezand 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. 2013 - 11 UFAM, CTGA Valeria Nogueira Machado; Emanuell Duarte Ribeiro; Rupert A.
