The larval stage of the genera Bugilliesia Lugo-Ortiz & McCafferty 1996; Cheleocloeon Wuillot & Gillies, 1993 and Delouardus Lugo-Ortiz & McCafferty, 1999 are remarkably similar. In order to avoid inaccuracy in generic placement, we propose new generic diagnoses with new discriminating characters. The setation of the labrum, details of the right and left prostheca, the shape of the maxillary palp and the shape of the legs are the most reliable characters for separating the different genera. Based on this, the generic attribution of Cheleocloeon mirandei Lugo-Ortiz & McCafferty, 1997 is incorrect and the species must be transferred to Bugilliesia as B. mirandei n. comb. A new species of Bugilliesia is described from South Africa. This greatly increases the distribution of Bugilliesia to include the whole of the Afrotropical region including Madagascar. A new species of Cheleocloeon is also described, confirming the presence of this genus in Madagascar.
