Larvae of Camerotrombidium pexatum (C. L. Koch, 1837) and C. rasum (Berlese, 1910) are described; diagnoses of larvae, deutonymphs and adults as well as data on their biology are provided. A female of C. pexatum, from which larvae were obtained by experimental rearing, has been designated as neotype. A revised diagnosis of Camerotrombidium is presented. The following new synonymies are proposed: Camerotrombidium rasum (Berlese, 1910) (= Compsothrombium absaloni Haitlinger, 1998) and Camerotrombidium pexatum (Koch, 1837) (= Compsothrombium luciolae Haitlinger, 1998). Data on habitat preferences, phenology, development timing and parasitic associations of larvae are given.
