Abstract
Yamasaki mentioned that male Amantis nawai (Shiraki, 1908) (Mantodea: Mantidae) is micropterous in Japan while macropterous in Taiwan. Based on different wing morphs, Yamasaki suggested that A. nawai in Taiwan and Japan should be classified into different species. However, this study reveals that micropterous and macropterous males in Taiwan are sympatric, and the offspring of both forms come from the same parents. Phylogenetic trees based on mitochondrial cytochrome oxidase II (COII) sequences do not distinguish the two wing morphs. Fixation index (FST = 0.040), and genetic distance (D) reveal no or little differentiation between different wing morphs. This result suggests that macropterous and micropterous male A. nawai in Taiwan belong to the same species. This is the first record of wing dimorphism in Mantodea. According to phylogenetic trees, and geographic distribution, A. nawai were separated into five populations, including north region (N), north-west region (NW), south-west region (SW), east region (E) of Taiwan, and Japan-Korea region (JK). Molecular analyses support the notion that A. nawai in Taiwan, Japan, and Korea should be the same species. Moreover, A. nawai of Japan-Korea region are more related to the eastern population of Taiwan. Fixation index (FST = 0.684-0.741) indicate that the four populations in Taiwan are highly differentiated. It may result from most collected samples are microptera with limited dispersal ability.
