The fossil history of worm lizards in Eastern Europe is very patchy because of the small number of localities and the fragmentary vertebral material available. A new record of the genus Blanus from the late Miocene of the Egorovka 1 and 2 localities in Ukraine is reported here. Based on its dental morphology, Blanus from Egorovka differs from all extinct species of the genus and from the extant B. cinereus complex. It is most closely related to the Eastern clade of Blanus (B. strauchi complex) in having enlarged second and small third dentary teeth. Blanus from Egorovka is the second fossil record of the B. strauchi complex and the first record of the Eastern clade outside of its current geographical range. It indicates a wider past range of the Eastern European Blanus, including the northern Black Sea coastal area.

东欧蠕虫蜥蜴的化石历史非常不完整，因为地点很少，而且可用的椎骨材料也很零碎。属的新纪录Blanus从Egorovka的晚中新世 1,2地方在乌克兰在这里报道。根据它的牙齿形态，Blanus从属的所有灭绝的物种不同Egorovka并从现存B.灰复杂。它与东部分支Blanus ( B. strauchi complex) 的关系最为密切，因为它具有增大的第二颗和小的第三颗牙齿。Blanus从Egorovka是第二化石记录B. strauchi复杂和东部进化支在其当前地理范围之外的第一个记录。它表明东欧白斑海豹的过去范围更广，包括黑海北部沿海地区。
