The egg cases, larvae, and pupae of Tropisternus (Pristoternus) latus (Brullé, 1837), T. (P.) ovalis Castelnau, 1840, and T. (P.) laevis (Sturm, 1826) are illustrated and described for the first time. The egg cases are built with or without a mast, which can be ribbon-like or globular; all larval instars have seven anterior denticles in the anterior margin of nasale, and the antennal seta AN8 is present; the pupae bear 6 or 8 styli on the abdominal segments II-VI, the pleural styli can be either short or very long, and horn-like projections may be present on the abdominal segments II-VI. A comparison of the morphology of the egg cases, pupae and larval chaetotaxic and morphometric characters within the genus Tropisternus is presented.
首次对宽角扁泥甲（Tropisternus (Pristoternus) latus，Brullé，1837）、卵形扁泥甲（T. (P.) ovalis，Castelnau，1840）和光滑扁泥甲（T. (P.) laevis，Sturm，1826）的卵鞘、幼虫和蛹进行了图示和描述。卵鞘的构建有或没有支柱，支柱可以是带状或球状；所有幼虫龄期在鼻前缘有七个前齿，且存在触角刚毛AN8；蛹在腹部第二至六节有6或8根花柱，胸膜花柱可以很短或很长，腹部第二至六节可能有角状突起。对扁泥甲属内卵鞘、蛹以及幼虫刚毛序和形态测量特征的形态进行了比较。
