New records of the beautiful dartfish, Ptereleotris kallista (Actinopterygii, Gobiiformes, Gobiidae), from southwestern Taiwan

The beautiful dartfish, Ptereleotris kallista Randall et Suzuki, 2008, is first recorded from Taiwan based on four specimens and a fresh photograph of an additional unretained specimen collected after typhoon events. Previously, this species was known from Luzon, the Philippines and the Milne Bay, Papua New Guinea; therefore, our specimens represent the northernmost record of this species. A detailed description and photographs of the Taiwanese specimens are provided and compared to the type specimens, with observed variations documented and discussed.
