Cryptic lineages in Neotropical freshwaters: an integrative approach reveals a new species of Megalonema (Siluriformes: Pimelodidae) from the upper Paraná River basin

Abstract A new species, previously identified as Megalonema platanum, is described as Megalonema tinga from the Paranapanema River basin, based on morphological (morphometry and meristic) and DNA-barcoding analyses. Body proportions based on 28 measurements in 25 specimens of M. tinga and 10 of M. platanum showed a hig...
