The new species Acaudinum (Acaudinum) rogeri sp.n. is described from Kazakhstan from Serratula coronata L. The new species is close to A. (Acaudinum) longisetosum Holman, 1970 and A. (Acaudinum) roumanicum Holman, 1991. It differs from both species in the proportion of the length of the last rostral segment to the length of the second segment of the hind tarsus (1.471.71 versus 1.221.55), the number of accessory setae on the last segment of the rostrum (46 versus 25). Fewer setae on the anterior margin of the genital plate (810 and 1024). It also differs from A. longisetosum in the ratio of siphunculi length to body length (0.130.20 versus 0.200.30), in having fewer setae on the cauda (1012 and 1317), and 8th abdominal tergite (46 in comparison with 59). From A. roumanicum with a longer second segment of the hind tarsus (0.140.19 mm and 0.120.15 mm). From A. centaureae (Koch, 1854) it is distinguished by setae on trochanters, femora, and ventral side of the body which is long and thin, and a fodder plant belonging to another genus of Asteraceae family. A comprehensive key to distinguish apterous viviparous females based on existing keys is provided.
新种无尾虫（无尾虫）罗杰 sp.n. 描述来自哈萨克斯坦从 Serratula coronata L. 新种接近 A. (无尾虫）longisetosum Holman, 1970 和 A. (无尾虫）roumanicum Holman, 1991. 它与这两个物种的区别在于最后一个吻部节段的长度与后跗节第二段的长度之比（1.471.71 对 1.221.55），吻部最后一节上的辅助刚毛数（46 对 25）。生殖板前缘的刚毛数较少（810 和 1024）。它也与 A. longisetosum 的不同之处在于体管长度与体长的比值（0.130.20 对 0.200.30），尾上的刚毛较少（1012 和 1317），以及 8 节腹部背板（46 对 59）。与后跗节第二段较长的 A. roumanicum（0.140.19 毫米和 0.120.15 毫米）。与 A. centaureae（Koch，1854）的区别在于，它的转节、股节和体腹侧有刚毛，而且是长而细的，以及属于菊科另一属的饲料植物。提供了一个基于现有钥匙的区分无翅胎生雌性的综合钥匙。
