Mohammed Ait Hammou and co-workers have recently published an article on the distribution and morphology of Androctonus liouvillei (Pallary, 1924) and A. aeneas C. L. Koch, 1839 (Buthidae) from Algeria. The study also looks into potential hybrid forms of the two species. Habitat differences and biogeography are also discussed.
Abstract:
This study updates the geographic distribution and examines the morphometric differentiation of Androctonus liouvillei, A. aeneas, and their putative hybrids in Algeria. By combining historical records with field surveys conducted between 2021 and 2024, several new localities for A. liouvillei in western Algeria were identified. Morphometric analyses of 12 adult females using Principal Component Analysis (PCA), Hierarchical Cluster Analysis (HCA), and Linear Discriminant Analysis (LDA), revealed key morphological differences and as well as intermediate forms. The results indicate that A. liouvillei has a restricted, and fragmented distribution, primarily associated with mid-altitude steppe habitats, whereas A. aeneas occupies a broader ecological range. Putative hybrids were recorded in sympatric zones, particularly in El Bayadh, Naâma, Béchar, and Tiaret, providing new insights into their biogeography and ecological differentiation.
