03D187CDAA20FF98FF08AFB3CA56F826.taxon	diagnosis	Diagnosis. Generally, species of Chrysotus from Guizhou are readily recognized from other Dolichopodidae, although this genus lacks distinct features, especially MSSC. It can be distinguished from closely related genera Diaphorus Meigen and Asyndetus Loew, especially the former, by the following characters: 1. Male frons usually wider than face; male face usually hidden by contiguous eyes, infrequently narrowly or widely separated. 2. Upper part of proepisternum bare, lower part of which above fore coxa with black setulae and black setae; claws usually visible and not fused to enlarged pulvilli. 3. Costa reaching to tip of M 1 + 2. R 2 + 3 straight or slightly curved towards costa, never forwardly at end. R 4 + 5 equally bent posteriorly, which usually runs parallel to M 1 + 2 apically, seldom very slightly divergent or convergent apically. 4. Male sternite 8 usually without stronger setae than those on tergite 6, although some taxa with a pair of stick-like setae; lateral epandrial lobe usually short and wide, never prominent (without specific strap-like lobe, which lacks strong setae); ventral projection of epandrium indistinct; surstylus and cercus simple, not divided into two lobes; hypandrium seldom simple, usually with process at apex. 5. Body smaller, with thorax and abdomen never yellow; antennae usually black (only C. gratiosus Becher, 1922 from Oriental Region with reddish yellow antennae).	en	Wei, Lianmeng, Zhang, Lili (2010): A taxonomic study on Chrysotus Meigen (Diptera: Dolichopodidae) from southwest China: descriptions of eleven new species belonging to the redefined C. laesus - group.

03D187CDAA20FF98FF08AFB3CA56F826.taxon	discussion	Remarks. The subfamily Diaphorinae consists of 18 genera (Yang et al. 2006), in which the two major genera, Diaphorus and Chrysotus are closely related and encompass more than 60 % of all species in the subfamily (Capellari & Amorim 2010). These two genera are poorly defined in relation to each other and also in relation to some other diaphorine genera (Bickel 1996, 2005). It often becomes difficult to identify unequivocally the species of diaphorine genera, especially species of these two genera. Consequently it is a difficult task to provide the exact placement of species on the basis of correct definitions of genera in Diaphorinae. Even though the above-mentioned five items delimit Chrysotus, it should be emphasized that the careful examination of internal genitalic structural characters of both male and female terminalia, which were often neglected previously, is an important source of phylogenetic information (Capellari & Amorim 2010). Chrysotus, as treated in this paper, is large and poorly defined genus with worldwide distribution. In Guizhou Province, southwest China, more than 150 species (about half of known species of the world) have been identified from about 10,000 specimens. Sorting these species into distinct species-groups based mainly on specific characters of the male terminalia is part of on-going studies. Habitat. Adults move about on grass and brushwood (never found on ground), especially about streams, pools and reservoirs, etc. Species of Chrysotus were collected with yellow pan traps in or nearby conifer and broadleaf forests, which are primary, secondary or artificial growth stands. In Guizhou Province, species of Chrysotus were collected from 100 m to 1800 m, but species appear to be more easily found below 1500 m.	en	Wei, Lianmeng, Zhang, Lili (2010): A taxonomic study on Chrysotus Meigen (Diptera: Dolichopodidae) from southwest China: descriptions of eleven new species belonging to the redefined C. laesus - group.

03D187CDAA23FF9BFF08AE99C894F954.taxon	diagnosis	Diagnosis. The C. laesus - group is herein redefined and can be distinguished from other members of Chrysotus by the following features: Epandrium with angular projection posteriorly (Fig. 2, peap). Hypandrium with process at apex. Postocular and occiput with setae usually black, seldom pale. Proboscis and palpus usually blackish brown, sometimes brownish black, seldom yellowish. Legs usually brownish black or black, at most individual species with femora yellowish at tip, with tibiae always more or less yellow (except C. laesus with tibiae black); sometimes with coxae and femora dark metallic green. Fore coxa usually with black setulae and setae anteriorly, but individual species with pale setulae and setae anteriorly (e. g., C. laesus, C. pallidus and C. serratus). Femora without row of long and developed setae (except C. guizhouensis with femora bearing two rows of long ventral setae). Base piles on anterior surface of hind tibia normal (fore, mid and hind tibiae with same base piles on anterior surface and vast majority of more than 150 species that have been found in Guizhou Province bear longer and denser basal piles on anterior surface of hind tibia). Halter usually pale at most brown or brownish black basally (except C. guizhouensis with halter brown). The Chrysotus laesus - group includes the following species: C. adunatus sp. nov. (Guizhou: Anshun, Jiaozishan, 1400 m) C. agraulus sp. nov. (Guizhou: Anshun, Ganpu, 1250 m) C. anshunus sp. nov. (Guizhou, Anshun, Jiaozishan, 1400 m) C. apicicaudatus sp. nov. (Guizhou: Daozhen, Dashahe, 1400 m) C. biprojicienus sp. nov.

03D187CDAA23FF9BFF08AE99C894F954.taxon	discussion	Remarks. Prior to this study, two Palaearctic species-groups, C. cilipes - group and C. laesus - group were recognized by Negrobov (1980). Unfortunately, they were poorly defined on the basis of “ light setae on fore coxae ”, and this feature is mostly unique to C. laesus, C. pallidus and C. serratus. In the above list of diagnostic characters, the posterior angular projection of the epandrium is found only in the C. laesus - group, a unique synapomorphy, and the remaining diagnostic characters above are usually present in the 16 new and known species. This derived character provides evidence for the re-evaluation of the C. laesus - group and consequently we have redefined the species-group in order to help organize and classify this large genus group.	en	Wei, Lianmeng, Zhang, Lili (2010): A taxonomic study on Chrysotus Meigen (Diptera: Dolichopodidae) from southwest China: descriptions of eleven new species belonging to the redefined C. laesus - group.

03D187CDAA2FFF96FF08ACACCB9DFEE4.taxon	discussion	Remarks. Based on characters of the terminalia, the new species is closely related to C. xinanus, sp. nov., but differs as outlined in the diagnosis. According to the key of Negrobov et al. (2000), the new species will run to C. nudisetus Negrobov et Maslova, 1995, but can be separated from the latter by the lateral epandrial lobe with distal margin concave; hypandrium with only a ventral process acute apically. Based on the key of Becker (1922), the new species will run to couplet 3, but differs from all species under the couplet by blackish brown femora and yellowish brown tibiae.	en	Wei, Lianmeng, Zhang, Lili (2010): A taxonomic study on Chrysotus Meigen (Diptera: Dolichopodidae) from southwest China: descriptions of eleven new species belonging to the redefined C. laesus - group.
