The primary and secondary chaetotaxy of the head capsule and head appendages of the three larval instars of the water scavenger beetle genus Derallus Sharp are described for the first time based on two species: D. angustus Sharp and D. paranensis Oliva. Morphometric characters derived from the head capsule and mouthparts are included, together with detailed illustrations of all characters. Chaetotaxy of these larvae is compared with that of Regimbartia attenuata (Fabricius), another species belonging to the Derallus-clade of Berosini.
窄水葬甲（Derallus angustus Sharp）和巴拉那水葬甲（Derallus paranensis Oliva），首次描述了水葬甲属（Derallus Sharp）三种幼虫龄期头部和头部附肢的原生和次生刚毛序。文中纳入了源自头部和口器的形态测量特征，以及所有特征的详细图示。将这些幼虫的刚毛序与贝罗西尼族（Berosini）水葬甲分支的另一个物种——瘦长拟葬甲（Regimbartia attenuata (Fabricius)）的刚毛序进行了比较。
