Two new species, Oswaldocruzia lisnykiensis sp. n. and Oswaldocruzia lacertica sp. n., are described from Anguis fragilis L. (Reptilia: Anquidae) and Lacerta agilis L. (Reptilia: Lacertidae) respectively. Both species belong to the Palaearctic group of species which have spicules divided in three main branches (blade, fork and shoe) with fork division above its distal third. The new species differs from all previously known Palaearctic species by several morphological characters: type of caudal bursa (type III in O. lisnykiensis and type I in O. lacertica), shape of spicules (blade distally divided into four tips and specific shape of shoe) and synlophe structure (narrow cervical alae consist of three crests in both species). Illustrated descriptions of O. lisnykiensis and O. lacertica based on 63 and 38 specimens respectively are presented. Host specificity and geographical distribution of the species are discussed. O. dispar is considered as a species inquirenda.
分别从脆蛇蜥（爬行纲：蛇蜥科）和捷蜥蜴（爬行纲：蜥蜴科）中描述了两个新物种，即利斯尼基奥斯瓦尔德吸虫新种和蜥蜴奥斯瓦尔德吸虫新种。这两个物种都属于古北区物种群，其交合刺分为三个主要分支（叶片、叉和靴），在其远端三分之一以上有叉状分支。新物种在几个形态特征上与所有先前已知的古北区物种不同：尾囊类型（利斯尼基奥斯瓦尔德吸虫为III型，蜥蜴奥斯瓦尔德吸虫为I型）、交合刺形状（叶片远端分为四个尖端和靴的特定形状）以及联合线结构（两个物种的狭窄颈部褶边均由三个嵴组成）。分别基于63个和38个标本给出了利斯尼基奥斯瓦尔德吸虫和蜥蜴奥斯瓦尔德吸虫的图示描述。讨论了物种的宿主特异性和地理分布。差异奥斯瓦尔德吸虫被视为有待进一步研究的物种。
