A new pycnodont fish from the early–mid Cenomanian, Late Cretaceous, of the ‘Ein Yabrud quarry near the village of Beit Eil in Israel is the first pycnodont fish to be described from this locality. Due to the locality where it was found, Scalacurvithys naishi gen. et sp. nov. is considered an inhabitant of reefal waters interspersed with lagoons in the eastern Tethys Sea. Scalacurvichthys naishi is notable for its protruding, hook-shaped first dorsal ridge scale above a large triangular dermatocranium, a deeply sloped and antero-posteriorly shortened skull and bifurcated cloacal scales. The bifurcating scales are a new character previously unknown in pycnodontomorph fishes but have been discovered in two more taxa, which indicates a new type of character that will be useful for future phylogenetic analyses of pycnodontomorph fishes. The new taxon is a member of Pycnodontidae and we conducted a phylogenetic analysis to establish its relationships to other pycnodont fishes. Our results reveal that Scalacurvichthys naishi is a well-resolved member of the subfamily Pycnodontinae.

来自以色列Beit Eil 村附近的'Ein Yabrud 采石场的Cenomanian 早中期，晚白垩纪的一种新的重齿目鱼是该地区描述的第一条重齿目鱼。由于发现地点，Scalacurvithys naishi gen。等人。十一月 被认为是特提斯海东部散布着泻湖的珊瑚礁水域的居民。鲇鱼以其突出的、钩形的第一背脊鳞片而闻名，该鳞片位于一个大三角形皮颅上方，一个深倾斜且前后缩短的颅骨和分叉的泄殖腔鳞片。分叉鳞片是一种新的特征，以前在 pycnodontomorph 鱼类中是未知的，但在另外两个分类群中被发现，这表明一种新的特征将有助于未来对 pycnodontomorph 鱼类的系统发育分析。新的分类群是 Pycnodontidae 的成员，我们进行了系统发育分析以确定其与其他 pycnodont 鱼类的关系。我们的研究结果表明，Scalacurvichthys naishi是 Pycnodontinae 亚科的一个很好解决的成员。
