摘要(Abstract)：

Vlakomia隶属于Cytheroidea超科Limnocytheridae科Limnocytherinae亚科,是亚洲东部地区早白垩世“Purbeck-Wealden型”介形类动物群的重要组成分子,广泛分布于我国及蒙古国早白垩世Barremian–Albian的含油气沉积盆地中。本文对Vlakomia属进行了全面的修订及厘定;据本次研究, Paralimnocythere是Vlakomia的同物异名, Vlakomia属目前包含9个有效种:Vlakomia ustinovskii, V. jilinensis, V. tumula, V. impolita, V. daerqiensis, V.quadrispinata, V. ulanense, V. mira和?V. temperata。Vlakomia是白垩纪陆相咸水介形类的代表分子,并且它还在油气勘探方面存在一定的指示意义。
The genus Vlakomia which belongs to the superfamily Cytheroidea, the family Limnocytheridae, and the subfamily Limnocytherinae, is one of the important elements of the “Purbeck-Wealden type” ostracod fauna from the East Asia. The species from this genus were widely distributed in the Barremian-Albian oil bearing sedimentary basins of China and Mongolia. In this study, we revised the genus Vlakomia, and the genus Paralimnocythere is considered a synonym of Vlakomia. Based on our revised work, the genus Vlakomia includes 9 species: Vlakomia ustinovskii, V.jilinensis, V. tumula, V. impolita, V. daerqiensis, V. quadrispinata, V. ulanense, V. mira and ?V. temperata. Vlakomia may indicate a saline lacustrine environment, and also shows an important significance in the hydrocarbon exploration.
