Two new species of Neanurinae (Collembola) are described from the Western Cape, South Africa: Ectonura monochaetasp. n. and Ectonura barraisp. n.Ectonura monochaetasp. n. differs from other species in the genus by its strongly reduced chaetotaxy, and the lateral shift of dorso-internal chaetae on Abd. V and their integration in the tubercles (De+DL). Ectonura barraisp. n. is similar to Ectonura natalensis (Womersley, 1934), but differs in chaetotaxic details and chaetal group arrangement. A key to the seven species of Neanurinae recorded from South Africa is given.
单毛外尾跳虫新种(Ectonura monochaeta sp. n.)和巴拉外尾跳虫新种(Ectonura barrai sp. n.)。单毛外尾跳虫新种与该属其他物种的区别在于其毛序显著简化,以及腹部V节背内侧刚毛侧向移位并融入瘤突(De+DL)。巴拉外尾跳虫新种与纳塔尔外尾跳虫(沃默斯利,1934年)相似,但在毛序细节和刚毛组排列上有所不同。给出了南非记录的七种短角跳虫科物种的检索表。
