1878年Hydrocassis Fairmaire属的幼虫形态是根据该属的三个物种进行描述的：Hydrocassis jengi Satô的第二龄，1998年，Hydrocassis lacustris的所有龄期（Sharp，1884年）和Hydrocassis uncinata Ji et Schödl的第二龄和第三龄，1998年；前两者属于肩胛水甲种群，后者属于舟状水甲种群。基于H.1龄幼虫描述的Hydrocassisis幼虫头部的初级毛毛趋化。 湖沼。根据文献中的描述和图片，总结了已知幼虫的所有Sperchopsini属的幼虫形态，并与Hydrocassisis进行了比较：Hydrocassisis的幼虫形态与Sperchopsis相似，而可能密切相关的Ametoris属通过幼虫形态特征与Hydrocassis区别开来。提供了基于幼虫特征的 Sperchopsini 属检索表。
The larval morphology of the genusHydrocassisFairmaire, 1878 is described on the basis of three species of the genus: second instar ofHydrocassis jengiSatô, 1998, all instars ofHydrocassis lacustris(Sharp, 1884) and second and third instars ofHydrocassis uncinataJi et Schödl, 1998; the former two belong to theHydrocassis scapulataspecies group and the latter to theHydrocassis scaphoidesspecies group. Primary chaetotaxy of the larval head ofHydrocassisis described based on the first instar larvae ofH. lacustris. Larval morphology of all genera of Sperchopsini with known larvae is summarized based on descriptions and figures from the literature, which are compared withHydrocassis: larval morphology ofHydrocassisis similar to that ofSperchopsis, and the presumably closely related genusAmetoris distinguishable fromHydrocassisby characters of larval morphology. A key to the Sperchopsini genera on the basis of larval characters is provided.
