Abstract: The family Anthomyzidae (Diptera: Acalyptrata) is recorded from China for the
first time based on 11 species, 6 of them new to science. A distinctive new
genus Marshallya gen. nov. is described, based on single peculiar species, M.
platythorax sp. nov. (both sexes) from Sichuan. Other new species, viz.
Amygdalops sevciki sp. nov. (Hainan I.) (both sexes), Epischnomyia tkoci sp.
nov. (Sichuan) (male only), Anthomyza ornata sp. nov. (Sichuan) (female only),
Anthomyza sulphurea sp. nov. (Yunnan) (both sexes) and Arganthomyza hyperseta
sp. nov. (Shaanxi) (male only) are described and illustrated in detail.
Male-female association of two Amygdalops species is clarified by means of
molecular barcoding and the female of A. bisinus Roháček, 2008 is correctly
identified and described. Relationships of all these taxa are discussed. Five
species, viz. Amygdalops bisinus (Hainan I.), Epischnomyia merzi Roháček,
2009, Anthomyza cuneata Roháček, 1987, Anthomyza trifurca Sueyoshi &
Roháček, 2003 (all from Sichuan) and Arganthomyza versitheca Roháček, 2009
(Shaanxi, Sichuan) are new additions to the Chinese fauna of Anthomyzidae. DNA
sequences of the barcoding region of COI have been obtained for 3 species,
Amygdalops bisinus, Amygdalops sevciki and Marshallya platythorax. Biology and
distribution of all 11 species are discussed. First photographs of living
Anthomyzidae from East Asia are presented. Based on knowledge of Anthomyzidae
from neighbouring areas the diversity of the Chinese fauna of the family is
estimated to include 50–60 species.
