Parahemiurus merus is a hemiurid widely dispersed and its life cycle is unknown. However, this species usually infects temperate pelagic fishes and chaetognaths. In this study, description and measurements of P. merus progenetic metacercariae found parasitizing Parasagitta friderici from Paranaguá Bay (Brazil) are presented. The prevalence was 86.8%, intensity of infection varied from 1 to 11, mean 2.26 and, mean abundance was 1.96 (n=190). In addition, some hosts were highly infected and the parasites released eggs inside its body cavity. These eggs were able to hatch inside the chaetognath. This is the first record of P. merus progenetic metacercariae infecting chaetognaths in Brazil.Downloads
