Two new species of Onychiuridae (Collembola) from Buryatia (Russia, East Siberia), Supraphorura chernovae sp. nov. and Thalassaphorura transbaikalica sp. nov., are herein described and illustrated. Supraphorura chernovae sp. nov. differs from its closest species, S. furcifera (Brner, 1901), by its dorsal pso formula as 32/022/23232, presence of 1 pso on the subcoxae 1 of all legs, and a larger set of vesicles on the PAO. Thalassaphorura transbaikalica sp. nov. is most similar to T. tibiotarsalis Sun, Chen & Deharveng, 2010 by the same dorsal pso formula (32/233/33343) and presence of 7 chaetae on the distal whorl of all tibiotarsi, but differs from the latter species specially by the presence of 1 pso on the subcoxa 1 of leg 1 (T. tibiotarsalis has 2 pso), number of vesicles on the PAO (1314 vs. 1718), number of chaetae on the subcoxa 1 of legs 13 (4, 4, 4 vs. 3, 3, 3), and ratio of the empodial appendage and claw (0.80.9 vs. 0.5). After our study there are now 47 recorded species of Onychiuridae recorded from East Siberia.
本文描述并图示了产自俄罗斯东西伯利亚的布里亚特共和国的 2 新种圆跳科（弹尾目）昆虫，即苏氏奇跳虫（Supraphorura chernovae sp. nov.）和跨贝加尔奇跳虫（Thalassaphorura transbaikalica sp. nov.）。苏氏奇跳虫与近缘种苏氏分叉跳虫（S. furcifera (Brner, 1901)）的主要区别在于其背面感器式为 32/022/23232，所有足的基节 1 上有 1 个感器，且前附腺的泡囊数量较大。跨贝加尔奇跳虫与 T. tibiotarsalis Sun, Chen & Deharveng, 2010 最为相似，其背面感器式（32/233/33343）和所有跗节远端卷上都有 7 根刚毛的特征相同，但与后者的主要区别在于第 1 足的基节 1 上有 1 个感器（T. tibiotarsalis 有 2 个），前附腺的泡囊数量（1314 对 1718），第 1 对足的基节 1 上的刚毛数量（4, 4, 4 对 3, 3, 3），以及外附刚毛和爪的比值（0.80.9 对 0.5）。我们的研究后，现共有 47 种圆跳科昆虫记录于东西伯利亚。
