Montreuil O. 2010. — Révision du genre Paradorodocia Machatschke, 1957 (Insecta, Coleoptera, Rutelidae, Adoretinae). Zoosystema 32 (1): 87-99.

Revision of the genus Paradorodocia Machatschke, 1957 (Insecta, Coleoptera, Rutelidae, Adoretinae).

The Adoretinae of the endemic Malagasy genus Paradorodocia Machatschke, 1957, are revised. A lectotype is designated for Adoretus albosetosus Waterhouse, 1878. Adoretus hystrix Künckel d'Herculais, 1887 and Adoretus albohispidus Fairmaire, 1883, are considered synonyms of Adoretus albosetosus. The lectotype of Adoretus albosetosus is designated as neotype of Adoretus hystrix Künckel d'Herculais, 1887 and of Adoretus albohispidus Fairmaire, 1883, which induces objective synonymies between these three names. Two new species are described and compared with their most closely related species: Paradorodocia elongata n. sp. and P. excavata n. sp. Paradorodocia fairmairei n. sp. is also introduced for the species named Adoretus hystrix by Fairmaire in 1897, which is not an available name. Based on this study, the genus Paradorodocia includes four species. Diagnostic characters for species in the genus include the shape of aedeagus, the shape and position of the metafemoral spurs, and the shape of the metasternum. Key to species, diagnoses, and distributions are provided. Endophallus and female genitalias are illustrated for the first time for this genus.
