Abstract

Anphira junki n.sp. (Isopoda. Cymothoidae) from the gill cavities of the fishes Triportheus albus and T. flavus is described. This parasite was found at various sites near Manaus in the Brazilian State of Amazonas. The new species differs from the other two species known for the genus in the form of the body, which is twisted posteriorly. Also, the dactyls are much longer, the cephalon is less depressed and the rami of the uropods are less acute.
