Comments: In Buenos Aires province, this species is reported to be found in the Salado River and in ponds, marshes and creeks within the Salado basin.  The Chascomús, Lobos and Lacombe lagoons are extensive water-bodies with abundant floating and submerged vegetation).  These lakes are a portion of a lenthic environment system which is one of the most remarkable features of the wet pampa. <i>Hyphessobrycon togoi</i>  is not abundant with respect to other species occurring in these lagoons, but it is sometimes caught in canals and flooded areas near the lagoons.  The Salado River crosses Buenos Aires Province from northwest to southeast, running for ca 690 km in the Pampasia and finally draining into Bahía de Samborombón.  The new species was also reported from Matanza River, a highly polluted environment draining into the Río de la Plata, where some of the most densely populated areas of Argentina lies along the middle and lower sections of this river, coupled with a high and complex industrial concentration (Ref. 57841).
