Contribuição ao conhecimento da oesteologia Pachypops adspersus (Steindachner): complexos cefálicos e caudal

Abstract

We have analised here the osteology of the cephalic bones and tail complex of young and adult fishes of the Pachypops adspersus (Steindachner) class, twenty of which were available, having in view the importance of these structural components on taxinomic, philogenetic and evolutive interpretation of the TELEOSTEI. The studied samples proceed from Dom Helvécio Lake, situated in the Parque Florestal do Vale do Rio Doce preserved area, in Minas Gerais State. The present study includes the neurocraneo and splancnocraneo. As for the tail complex, we presented the morphology of the tail fin and the spinal column elements, responsible for it. With the obtained results, it is still discussed the philogenetic position of the species studied among the PERCOIDEI.
