Abstract
Two new species of the genus Hetereleotris are described from the south Pacific. One species is known only from reefs off southeastern Australia and the second from Rapa and Pitcairn islands. Both species are close to a species recently described from Easter Island in the genus Pascua. The Easter Island species is redescribed herein. Previously only one species of the genus was reported from the Pacific. All of the species described here share a number of characteristics suggesting that they form a monophyletic group, including: the flattened and elongate urogenital papilla of the males, modified basicaudal scales, posterior nostril a simple pore or with only a slightly elevated margin anteriorly, two papillae just behind the mental frenum and the reduced transverse papilla pattern.References
