New taxonomic status of Tripteroides bambusa (Yamada), 1917 from Japan, based on experimental crossing and COI sequence divergence

Abstract

Tripteroides bambusa bambusa (Yamada) from the Palaearctic region of Japan, and Tp. b. yaeyamensis Tanaka, Mizusawa and Saugstad from Yaeyama Islands of the Ryukyu Archipelago, Japan were elevated to the rank of full species, Tp. bambusa and Tp. yaeyamensis, respectively. The specific status was based on the demonstration of the morphological distinction, the allopatric distribution, the sterile reciprocal cross, and the DNA sequence diversity of the cytochrome c oxidase subunit I (COI).
