On distribution of Nannoarctia species in China (Lepidoptera, Arctiidae)

All available material of the genus Nannoarctia Koda from China is considered. All but one formerly known specimens appeared to belong to N. obliquifascia Hmps., although earlier they had been identified as two species. The second species, N. tripartita Wlk. is still known by a single specimen from Yunnan only. Taxonomy of the genus Nannoarctia Koda, 1988 is very complicated due to individual variability of the wing pattern and male genitalia. This problem was strongly complicated by different and not conspecific type designation of N. tripartita (Walker, 1855) by Butler (1881) and Hampson (1894, 1901). Dubatolov & Kishida (2010) following Cerny & Pinratana (2009) chose the latter as the lectotype because it corresponds to var. by Walker (1855). Moreover, neither image of the N. tripartita variation sensu Walker (1855) nor a comprehensive explanation of the specific problem in this group were published. So, in spite of presence of two distinct species in the South-East Asian fauna, many authors could not separate them from each other. The same concern Nannoarctia species from China. After Cerny & Pinratana (2009) and Dubatolov & Kishida (2010) reviews, it became necessary to reattribute all known Nannoarctia material from China into correct species.
