摘要
本文描述了分布于中国广西的叉隙蛛属(Bifidocoelotes Wang,2002)两新种:槽状叉隙蛛新种B.alviolatus sp.nov.(♂ ♀)和宽叉隙蛛新种B.latus sp.nov.(♀),并首次描述了长叉隙蛛B.elongatus Liao,Wang,Yin & Xu,2022的雄蛛.文章提供了蜘蛛外形和生殖器结构彩色照片以及叉隙蛛属地理分布图.此外,提供了叉隙蛛属四个物种的DNA条形码,包括一个新种(槽状叉隙蛛新种B.alviolatus sp.nov.)和三个已知物种(乳状叉隙蛛B.mammiformis Liao et al.,2022;方形叉隙蛛B.quadratus Liao et al.,2022 和长叉隙蛛 B.elongatus Liao et al.,2022).
