Notes

Identification to species level follows Buitrago-Suárez 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-Suárez 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-Suárez 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.
