No. of bitstreams: 1 200909.pdf: 2799695 bytes, checksum: 3f7db4b7ea0866099b1da9bd33e167a6 (MD5) Previous issue date: 1980 / Com base em um grupo de vinte exemplares de Pachypops adspersus (Steindachner), indivíduos jovens e adultos, é analisada a osteologia de seu esqueleto cefálico e complexo caudal, considerando a importância desses componentes estruturais nas interpretações taxionômicas, filogenêtica e evolutiva dos TELEOSTEI. O material observado procede do Lago Dom Helvécio, situado na área preservada do Parque Florestal do Vale do Rio Doce, no Estado de Minas Gerais. O estudo em questão inclui as estruturas do neurocrânio e do esplancnocrânio. Sobre o complexo caudal aborda-se a morfologia da nadadeira caudal e os elementos da coluna vertebral responsáveis pela sustentação da mesma. Com os resultados obtidos discute-se ainda a posição filogenética da espécie estudada entre os PERCOIDEI. / 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.
