Introduction Takeuchi 1927, 1939; Doi 1938; Kim 1957, 1963, 1970; Togashi 1973, 1990, 1997; Zombori 1974, 1978; Paek et al 2010; Shinohara Taeger et al (2010) listed 58 genera and 913 valid species and et al 2009; Shinohara et al 2012). Recently, 2 species within 2 subspecies under Argidae. After that, at least 17 papers dealing with genera were reported from South Korea (Choi et al 2015). new argid species were published until the end of 2015 (Choi et al In Northeastern Asia, only 2 genera of Arginae have been 2015; Hara and Shinohara 2012a, 2012b, 2013, 2014a,b; Koch 2010, recorded: Arge Schrank, 1802 and Spinarge Wei, 1998.

Keys to Arge species from Japan 2006; Wei 2008; Zhang and Wei 2008; Yan et al 2009; Wei and Niu (Takeuchi 1939), India (Saini and Thind 1995), Europe (Muche 2010; Wei et al 2013; Shinohara et al 2015). The fauna of Argidae 1977), Africa (Pasteels 1953), North America (Smith 1989), and have been poorly investigated in South Korea and only 21 species the Palaearctic (Gussakovskij 1935) are available, although some and 3 genera have been recorded from Korea (Gussakovskij 1935; are outdated. The key to Palaearctic species of Argidae by Gussakovskij (1935) is still useful for investigating the Asian fauna of Argidae, but researchers should not rely on the key too much because at least six genera and 127 species have been added to * Corresponding author.
