Etude des populations Marocaines de la superespece Camponotus cruentatus Latreille. Mise en evidence de Camponotus obscuriventris sp. n. (Hymenoptera, Formicidae)
[EN] Multivariate analysis (PCA, DFA) and morphological data have been used to study 72 Moroccan population samples of Camponotus (superspecies) cruentatus Latr. and 7 samples of various origins including the original types of «varieties» cruentior Santschi, 1931 and lindbergi Santschi, 1931.

| Sumario: | [EN] Multivariate analysis (PCA, DFA) and morphological data have been used to study 72 Moroccan population samples of Camponotus (superspecies) cruentatus Latr. and 7 samples of various origins including the original types of «varieties» cruentior Santschi, 1931 and lindbergi Santschi, 1931. A new taxonomy of the ant-group Camponotus cruentatus is propounded, as including a single superspecies Camponotus cruentatus Latr. with three vicariant species: Camponotus cruentatus (Latreille, 1802) distributed from the High Atlas to North of Italy, Camponotus obscuriventris sp. n., located in the High Atlas of Marrakech, with a marginal population in the Tizi-n-Test and Camponotus pexus Santschi, 1929 from the extrem western High Atlas and Souss; its validity as a good species is corroborated. The morphs cruentior Sants. and lindbergi Sants. of C. cruentatus (Latr.) are regional morphotypes (from Rif and Middle Atlas of Azrou, respectively) besides other regional morphotypes. The population from southeastern France was found corresponding to Latreille's cruentatus typical form. The obviousness of colours changes and alterations of body part proportions in relation to local ecological conditions are shown; populations from cold and damp localities (in elevated or in forest stations) present generally a darkening of the coloration patterns and a shortening of the scapes and tibiae. A hypothesis of a Moroccan origin for the superspecies C. cruentatus Latr. is presented. |
