DESCRIPTION OF TWO NEW SPECIES OF Crenicichla (TELEOSTEI: CICHLIDAE) FROM THE LOWER IGUAZÚ RIVER WITH A TAXONOMIC REAPPRAISAL OF C. iguassuensis, C. tesay AND C. yaha

Popis výsledku v původním jazyce

Five species of Crenicichla have been recorded so far from the lower Iguazú River. Four of them are endemic (members of the C. mandelburgeri species complex from the C. lacustris group) and living in sympatry; the fifth species (C. lepidota) belongs to an Amazon/Orinoco-centered species group (C. saxatilis) and is only distantly related to the remaining species. The four sympatric species differ substantially in their head/teeth morphology and related utilization of the ecological niches, and representall known ecomorphs within Crenicichla. Two of them, a gregarious small-mouthed picker/grazer C. tapii sp. n. and a large-mouthed thick-lipped cavity explorer/excavator C. tuca sp. n. are described here as new species. The piscivorous large-mouthed species C. iguassuensis represents the ancestral form of the genus. The fourth species is the small-mouthed picker/molluscivore C. tesay with a robust lower pharyngeal jaw with molariform teeth. Populations referred to in previous studies as C
