This publication includes several contributions usually published as short notes. Taxonomic issues of three species-group names of the genus Agama Daudin, 1802 are discussed: the proposed name bearing type of Agama aculeata Merrem, 1820 is corrected; Agama namaquensis Werner, 1910 is identified as synonym of Agama anchietae ; and Agama agama mucosoensis Hellmich, 1957 is elevated to species rank. Moreover, the first report of single introductions of Agama africana and, as additional note, of Chamaeleo chamaeleon to Madeira Island (Portugal) is presented.

In the course of recent taxonomic studies of the genus Agama we revised East African taxa of the Agama agama group. In this paper, we resurrect A. agama kaimosae Loveridge, 1935 from synonymy of Agama caudospinosa and elevate it to full species rank. Studies of the morphology, color pattern and genetic distance indicate that Agama kaimosae is most closely related to A. mwanzae and to A. caudospinosa . It is clearly distinct and genetic distant to A. planiceps and the A. lionotus and A. agama complexes. New distribution records and the first photograph of a living male of A. kaimosae are provided.

Suggestion d'un possible benefice additionnel de la perte de la queue et de sa regeneration chez le lezard A. agama et proposition d'un role eventuel au niveau des interactions sociales entre les mâles, de la structure en masse des queues regenerees, par augmentation de leur efficacite de fouettage
