Six New Species of the Genus Promalactis Meyrick (Lepidoptera, Oecophoridae) from Vietnam

다국어 초록 (Multilingual Abstract)

The genus Promalctis Meyrick, 1908 is the largest genus of the family Oecophoridae, with more than 150 described species in the world (Wang et al., 2009; Du et al., 2009). The genus is mainly distributed in the Palaearctic and Oriental regions, probably with the highest diversity in the South and East Asia. However it has been very poorly studied to date, with only with only 4 publications which were based on very limited collecting. In total, 76 were reported from China, which is more than half of the known species in the Palaearctic region(Wang, 2006; Du et al., 2009), 14 species known from Korea (Park & Park, 1998), 12 species from Japan (Fujusawa, 2002), 8 species from Russian Far East (Lvovsky, 1976, 1985, 1986), and 3 species from Nepal (Lvovsky, 2000a). In the Oriental region, since Meyrick (1908a, 1908b) described 14 species from India and Myanmar, Lvovsky (2000a, 2000b) described 25 additional species from the southern Asia, including the southern part of China, Malaysia, Indonesia, and the Philippines. In Vietnam, only 4 species, Promalactis albiapicalis Lvovsky 1997, P. buonluoi Lvovsky 1997, P. fansipanella Lvovsky 2007, and P. suzukiella (Matsumura 1931), have been described to date(Lvovsky, 1997, 2007a). The aim of this study is to describe six new species of Promalactis based on material mainly collected in the northern part of Vietnam. Adults, head parts, wing venations, and the male or female genitalia of the new species are illustrated.
