Psalidodon Togoi

📖 Overview

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. Hyphessobrycon togoi 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 .

Vertebrae: 35. This species can be distinguished from all its congeners, except Hyphessobrycon langeanii Lima & Moreira, in having a well-defined, round to horizontally oval humeral spot. It differs from H. langeanii by the possession of a second humeral spot (vs. absent), maxilla not reaching anterior edge of orbit (vs. maxilla reaching middle of orbit) and infraorbitals 3 and 4 separated (vs. coossified). Other diagnostic characters of H. togoi include: a short expanded maxilla with 1 large multicuspid tooth; premaxilla with an outer row of 3 small teeth, with 5 or 6 cusps, relatively apart from each other; an inner series with 5 teeth that are distally broader, with numerous cusps (6-11) and overlapping each other; iv-v, 17-20 anal-fin rays; 31-36 scales on the longitudinal series; presence of bony hooks on all fins of the mature males . : short and / or deep; Cross section: compressed.
