First Anthomyzidae (Diptera) from China: a new genus, six new species and new records Author Roháček, Jindřich text Acta Entomologica Musei Nationalis Pragae 2018 2018-04-25 58 1 35 76 journal article 10.2478/aemnp-2018-0007 5397a3ac-ffb7-408e-ab5b-50be49c2331d 1804-6487 3676725 9808C120-13B7-43F8-B735-C13D2B6D43CA Arganthomyza versitheca Roháček, 2009 Material examined. CHINA : SHAANXI : Fuping-x, Banbianhe, 1.5 km N of Longcaoping, 1300–1360 m , 4.vii.1997 , 1, T. Saigusa leg. ( SIINH , genit. prep.). SICHUAN : Pingwu Co., Laohegou Reserve, 32°29′3.20′′N 104°43′9.96′′E , 1400–2100 m , 13.–17.v.2016 , 2 3 ♀♀ , O. Lonsdale leg. ( CNCI , 1 1 ♀ genit. prep.). Remarks. Another representative of the Arganthomyza setiplanta group (delimited by ROHÁČEK & BARBER 2013 ). As noted above it is obviously the nearest relative (sister species) of A. hyperseta sp. nov. (described above) while the Nearctic A. carbo Roháček & Barber, 2013 is the next closest ally to this pair. The remaining (most ancestral) species of the group seems to be A. setiplanta ( Roháček, 1987 ) from Nepal . Biology. The type series was captured in montane forests of South Korea ( 750–1200 m ) in June. The Shaanxi and Sichuan specimens expand both flight period (to May, July) and altitude range ( 1300–2100 m ) of the species. The species is probably associated with the undergrowth of moist leafy forests (see ROHÁČEK & BARBER 2013 : Fig. 52 ). Distribution. South Korea ( ROHÁČEK 2009 ), China : Shaanxi , Sichuan (first records).
