BioOne Complete (complete.BioOne.org) is a full-text database of 200 subscribed and open-access titles in the biological, ecological, and environmental sciences published by nonprofit societies, associations, museums, institutions, and presses.

Two new species of the genus Xanthochlorus from China (Diptera, Dolichopodidae, Xanthochlorinae)

“…Mid tarsomere one with two short weak av. Dorsal surstylus acute and curved apically, ventral surstylus wide, furcated apically; cercus bent, wide basally and finger-like apically; hypandrium basally with short hook-like lateral protuberance, apically deeply incised with lateral protuberance, slightly curved (Xi et al 2015: p 315, fig 5).…”

“…Compared to the other subfamilies of Dolichopodidae, most of which have high diversity, the genus Xanthochlorus has a low species number. There are presently 18 known species of Xanthochlorus in the world (Yang et al 2006, 2011, Grichanov 2017), with only four species known in China: Xanthochlorus chinensis Yang & Saigusa, X. nigricilius Olejníček, X. henanensis Wang, Yang & Grootaert and X. tibetensis Xi, Wang & Yang (Olejníček 2004, Yang and Saigusa 2005, Wang et al 2008, Yang et al 2011, Xi et al 2015). They have been reported from Shaanxi, Henan, and Tibet, which are, respectively, in the northwest and middle of China.…”

The mitochondrial genome of Xanthochlorus tibetensis (Diptera: Dolichopodidae)

“…Xanthochlorus tibetensis was described in 2015 with material from subtropical forest in Tibet (China) (Xi et al. 2015 ), and was first found from Tajikistan when we checked materials from Tajikistan this summer. This special species is mainly yellow in thorax and abdomen with yellow bristles, bearing nearly quadrate first flagellomere.…”

“…This special species is mainly yellow in thorax and abdomen with yellow bristles, bearing nearly quadrate first flagellomere. Male abdominal tergite 6 is large and genitalia is rather large and mostly exposed with modified cercus, and female abdomen is wide and obtuse apically (Yang et al 2006(Yang et al , 2011Xi et al 2015).…”
