Abstract
The extremely paedomorphic fish Schindleria (Gobioidei, Schindleriidae) is widely distributed in the Indo-Pacific Ocean, inhabiting coral reef lagoons. At least 21 cryptic species (Schindleria spp. 1–21) have been discovered around the Ryukyu and Ogasawara Islands. As a first step in extending the survey areas to the entire Indo-Pacific Ocean, the present study collected and examined Schindleria in Palau, located approximately 2,200 km from the Ryukyu Islands, for any cryptic diversity. Molecular phylogenetic analysis using partial mitochondrial 16S rRNA sequences of 71 specimens revealed four new cryptic species of Schindleria spp. 22–25 (Palau 1–4) in Palau.
