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).
