| Research Abstract |
In the present project, I have obtained more than 1,500 Schindleria specimens from Hawaii, Palau, Indonesia, Thailand, and Okinawa. Molecular phylogenetic analysis detected five species in Palauan specimens and revealed four new cryptic species of the five ones. These four species were endemic to Palau, suggesting that the level of endemism is high in Schindleria. The resultant phylogenetic trees based on whole mitochondrial DNA sequences strongly supported that all Schindleria species are placed as sister group to Oxymetopon in Microdesmidae+Ptereleotridae.
