ABSTRACT
A total of 36 species and 11 genera of the fly family Lauxanidae have been previously recorded in Korean Peninsula. As a result of our ongoing study of this family, we here report the following nine species new to Korea: Homoneura albomarginata Czerny, 1932, Minettia filia (Becker), 1895, Pachycerina alutacea Shatalkin, 1998, Poecilolycia zherichini Shatalkin, 2000, Protrigonometopus sexlituris (Shatalkin), 1992, Salebrifacies czurkini Shatalkin, 1992, Sapromyza albiceps Fallén, 1820, Steganopsis dichroa Shatalkin, 1998, and Trigonometopus eborifacies Shatalkin, 1997. The genera Poecilolycia Shewell, 1986, Salebrifacies Shatalkin, 1992, and Steganopsis de Meijere, 1910 are recognized for the first time in this country. Therefore, 45 species in 14 genera are now officially recognized for the Korean lauxaniid fauna. In addition, we provide diagnoses and color photographs of adult external structures including male genitalia to aid their specific identification. Keywords: Lauxaniidae, Lauxaniinae, Homoneurinae, taxonomy, Korea
INTRODUCTION we here report the following nine species new to Korea: Homoneura albomarginata Czerny, 1932, Minettia filia The family Lauxaniidae is a large family of acalyptrate flies (Becker), 1895, Pachycerina alutacea Shatalkin, 1998, with about 1,838 described species worldwide as of Septem Poecilolycia zherichini Shatalkin, 2000, Protrigonometopus ber 2015 (The Diptera Site). Lauxaniid flies are usually found sexlituris (Shatalkin), 1992, Salebrifacies czurkini Shatalkin, in moist shady undergrowth, grassland, all forest types, sand 1992, Sapromyza albiceps Fallén, 1820, Steganopsis dichroa dunes, mangrove swamps and even on mountain summits Shatalkin, 1998, and Trigonometopus eborifacies Shatalkin, (Kim, 1994). Saprophagous larval stages are found in leaf 1997. The genera Poecilolycia Shewell, 1986, Salebrifacies litter, decaying vegetation and similar habitats (Kim, 1994). Shatalkin, 1992, and Steganopsis de Meijere, 1910 are recog Taxonomic investigation of Korean members of the family nized for the first time in this country. Therefore, 45 species Lauxaniidae was initiated by Papp (1984a), who reported and 14 genera are now officially recognized for the Korean eight Homoneura species including three new species from lauxaniid fauna. In addition, we provide diagnoses and color North Korea.

In South Korea, a total of 14 species and five genera are previously reported by various taxonomic inves MATERIALS AND METHODS tigations including our recent studies (Lee and Han, 2009, 2014a, 2014b). In total, 36 species and 11 genera are current Terminology and morphological interpretations follow Merz ly known in Korean Peninsula (Han et al., 2014; Lee and and Haenni (2000).
