Nuconarius gen. n. and Hengconarius gen. n., two new genera of Coelotinae (Araneae, Agelenidae) spiders from Southwest China.

Two new genera of Coelotinae F.O.Pickard-Cambridge, 1893 from Southwest China are described: Nuconarius Z. Zhao S. Li gen. n. and Hengconarius Z. Zhao S. Li gen. n. The type species of Nuconarius Z. Zhao S. Li gen. n. is N. brevipatellatus Z. Zhao S. Li sp. n. and two additional species also belong here: N. capitulatus (Wang, 2003) comb. n. and N. pseudocapitulatus (Wang, 2003) comb. n. The type species of Hengconarius Z. Zhao S. Li gen. n. is H. exilis (Zhang, Zhu Wang, 2005) comb. n. and this genus includes seven additional species: H. dedaensis Z. Zhao S. Li sp. n., H. falcatus (Xu Li, 2006) comb. n., H. incertus (Wang, 2003) comb. n., H. latusincertus (Wang, Griswold Miller, 2010) comb. n., H. longipalpus Z. Zhao S. Li sp. n., H. longpuensis Z. Zhao S. Li sp. n. and H. pseudobrunneus (Wang, 2003) comb. n. All species are from Southwest China and their distributions are mapped. New combinations are all ex-Draconarius Ovtchinnikov, 1999. The male of N. capitulatus is matched correctly for the first time and the DNA barcodes of all species are documented.
