Molecular phylogenetic analysis of theAmiota apodemataandAmiota sinuataspecies groups (Diptera: Drosophilidae), with descriptions of four new species

“…Amiota aculeata Chen & Aotsuka in Chen et al ., (China, Hainan, Yunnan); Amiota bicolorata Bock, (Australia, Queensland); Amiota bispinula Chen & Toda in Chen et al ., (Malaysia, Sabah); Amiota cerata Chen & Toda in Chen et al ., (Malaysia, Sarawak); Amiota curvibacula Chen & Toda in Chen et al ., (Malaysia, Sabah); Amiota hernowoi Chen & Toda, 1998b (Indonesia, West Kalimantan); Amiota javaensis Chen & Toda, 1998b (Indonesia, Java); Amiota lambirensis Chen & Toda in Chen et al ., (China, Hainan, Yunnan; Malaysia, Sarawak); Amiota parviserrata Chen & Toda in Chen et al ., (Malaysia, Sabah); Amiota pengi Chen & Toda, 1998b (China, Hainan); Amiota pontianakensis Chen & Toda, 1998b (Indonesia, West Kalimantan); Amiota quadrifoliolata Chen & Toda in Chen et al ., (Malaysia, Sabah); Amiota ratnae Chen & Toda, 1998b (Indonesia, Java); Amiota sinuata Okada, 1968 (Japan, Kyushu, Ryukyu Islands; China, Guangdong, Hainan, Yunnan; Myanmar; New Guinea); Amiota subsinuata Chen & Aotsuka in Chen et al ., (China, Yunnan); Amiota xishuangbanna Chen & Aotsuka in Chen et al ., (China, Yunnan); Amiota guiensis Xu & Chen sp. nov. (China, Guangxi); Amiota hesongensis Xu & Chen sp.…”

“…The apodemata group includes only four known species from the Oriental region (China, India, Indonesia, and Myanmar), and bears the following characteristics: male fifth tergite with dark-coloured strips laterally; male sixth tergite very small, pointed laterally, and not reaching ventral margin of fifth tergite; aedeagus developed, basally fused to apodeme (Chen & Toda, 2001). All the species in the sinuata group, except for Amiota aculeata Chen & Aotsuka, 2005 from Yunnan, China (Chen et al, 2005), lack the prescutellar setae, which is present in all other lineages of the subfamily Steganinae. Until now, this group included 16 known species from China (Guangdong, Guangxi, Hainan, and Yunnan), Japan (Okinawa and Kyushu), Southeast Asia, Papua New Guinea, and Australia (Queensland) (Chen & Toda, 2001;Chen et al, 2004Chen et al, , 2005Chen et al, , 2007.…”

Chen & Toda (2001) performed a cladistic analysis of the Asian and European Amiota species based on 31 adult morphological characters.…”

Amiota sinuata species group from eastern Malaysia (Diptera, Drosophilidae)

“…The Amiota sinuata species group was established by Chen and Toda (1998), including small, yellow to brownish flies that are usually collected on tree trunks or around human eyes and lack prescutellar setae, which are usually present in the genus Amiota Loew. However, Chen et al . (2005) reported an exceptional species, Amiota aculeata Chen and Aotsuka, which has the prescutellar setae but shares the characters of the male genitalia with the sinuata group.…”

“…(2005) reported an exceptional species, Amiota aculeata Chen and Aotsuka, which has the prescutellar setae but shares the characters of the male genitalia with the sinuata group. To date, 10 species have been identified from Australia, South‐East Asia, China (Guangdong, Hainan, Yunnan) and Japan (Okinawa, Kyushu) (Okada 1968; Bock 1989; Chen & Toda 1998; Chen et al . 2004, 2005).…”
