中国西南地区龙隙蛛属2新种记述（蜘蛛目：漏斗蛛科：隙蛛亚科）

Two New Species of the Genus Draconarius Ovtchinnikov, 1999 from Southwest China(Araneae: Agelenidae: Coelotinae)

记述采自中国西南地区的漏斗蛛科(Agelenidae)龙隙蛛属(Draconarius Ovtchinnikov,1999)2新种:极短龙隙蛛Draconarius paululus sp. nov.和笑龙隙蛛Draconarius risusus sp. nov.。2新种同属于无刺龙隙蛛组D. aspinatus-group。另外,还提供了笑龙隙蛛D. risusus sp. nov.的标准条形码COI基因序列。通过Kimura 2-parameter(k2p)遗传距离分析,笑龙隙蛛与其他13种龙隙蛛已知种具有明显的间隙,其种内遗传距离为0.0%~0.4%,而种间遗传距离为7.1%~20.4%。

The paper deals with two new species of the family Agelenidae and the genus Draconarius Ovtchinnikov, 1999:Draconarius paululus sp. nov. and Draconarius risusus sp. nov., from southwest China. The genital organs indicate that they both belong to the D. aspinatus-group. The DNA sequence data of cytochrome oxidase subunit I(COI)gene fragment(standard DNA barcodes)of D. risusus sp. nov. are also provided. It is unambiguously distinguished from 13 known species of Draconarius based on Kimura2-parameter(k2 p)distances: intraspecific distances range from 0.0%~0.4%;interspecific distances range from 7.1%~20.4%.
