A new genus is proposed based on a new species from Iran, Ephemerotoma skarzynskii gen. et sp. nov., and three known species: E. huadongensis (Chen, 1985) comb. nov., E. multituberculata (Martynova, 1971) comb. nov. and E. porcella (Ellis, 1976) comb. nov. The genus shares the characters of Subisotoma Stach and Proctostephanus Börner and is distributed in southern areas of Eurasia (Eastern Mediterranean, Iran, Tajikistan, China). Ephemerotoma gen. nov. belongs to the Proisotoma-complex and is characterized by a simple maxillary palp, only 4 guards on labial papilla E and 2 prelabral chaetae. Four s-chaetae on Abd.V are arranged in two rows, two anterior and two posterior chaetae. All members of Ephemerotoma gen. nov. are redescribed or discussed based on type or fresh material, and a key to species of the genus is given. Scutisotoma potapovi Xie & Chen, 2008 is considered a synonym of E. huadongensis, while Proisotoma anopolitana is moved to the genus Proctostephanus. Sexual dimorphism is described for three species.
基于来自伊朗的一个新物种——斯卡日恩斯基短角跳虫新属新种（Ephemerotoma skarzynskii gen. et sp. nov.）以及三个已知物种：华东短角跳虫（Ephemerotoma huadongensis (Chen, 1985) comb. nov.）、多瘤短角跳虫（Ephemerotoma multituberculata (Martynova, 1971) comb. nov.）和小猪短角跳虫（Ephemerotoma porcella (Ellis, 1976) comb. nov.），提出了一个新属。该属具有近等跳虫属（Subisotoma Stach）和前突跳虫属（Proctostephanus Börner）的特征，分布于欧亚大陆南部地区（东地中海、伊朗、塔吉克斯坦、中国）。短角跳虫新属属于原等跳虫复合体，其特征为简单的下颚须、唇乳头E上仅有4根保护刚毛以及2根唇前刚毛。腹部V节上的4根s刚毛排成两行，前排和后排各两根刚毛。基于模式标本或新鲜标本对短角跳虫新属的所有成员进行了重新描述或讨论，并给出了该属物种检索表。2008年谢和陈描述的波塔波夫皮壳跳虫（Scutisotoma potapovi）被认为是华东短角跳虫的同物异名，而无肛原等跳虫（Proisotoma anopolitana）被移入前突跳虫属。描述了三个物种的两性异形。
