ABSTRACT Two poorly known members of Bothremydidae, previously recognized as representatives of the genus Taphrosphys, but subsequently considered as not attributable to any of the genera so far defined, are analyzed here. Two genera are defined for these members of Taphrosphyina, each one of them being characterized by autapomorphies and by a unique character combination. The French Maastrichtian (Upper Cretaceous) species ‘Tretosternum’ ambiguum is attributed to the new genus Eotaphrosphys, and the Peruvian Ypresian (lower Eocene) form ‘Podocnemis’ olssoni to the new genus Motelomama. Eotaphrosphys is the oldest named genus of Taphrosphyina, and the only one defined in Mesozoic levels. Eotaphrosphys ambiguum is the only member of this clade recognized in Europe, Motelomama olssoni representing the only one identified in the South American record. ZooBank LSID for the genus Eotaphrosphys ambiguum is: urn:lsid:zoobank.org:act:16FAD98A-DA04-4933-AD99-88663CE74D6C ZooBank LSID for the genus Motelomama gen is: urn:lsid:zoobank.org:act:3E832D96-29B1-4589-B397-B57768DB39A9

Taphrosphyina (Pleurodira, Bothremydidae) 的新属,用于法国 Maastrichtian 'Tretosternum' ambiguum 和秘鲁伊普雷西亚 'Podocnemis' olssoni
摘要这里分析了两个鲜为人知的 Bothremydidae 成员,以前被认为是 Taphrosphys 属的代表,但后来被认为不属于迄今为止定义的任何属。为这些 Taphrosphyina 成员定义了两个属,每个属都具有自体同源性和独特的性状组合特征。法国马斯特里赫特(上白垩纪)物种 'Tretosternum' ambiguum 归属于新属 Eotaphrosphys,而秘鲁伊普雷西亚(下始新世)则形成了新属 Motelomama 的 'Podocnemis' olssoni。Eotaphrosphys 是最古老的 Taphrosphyina 属,也是唯一一个在中生代水平上定义的属。Eotaphrosphys ambiguum 是该分支中唯一在欧洲得到认可的成员,Motelomama olssoni 是南美记录中唯一确定的成员。
