Figs 19-21: SEM micrographs of heads in full-face view (a) and overall lateral view (b) of ant workers. 19: Camponotus atlantis , large worker. 20: Camponotus atlantis , small worker. 21: Camponotus hova , small worker. SEM: H. Pohl. Remarks: Occurring throughout the island complex off the African coast in the Indian Ocean, this species can be regarded as a Malagasy faunal element. It has a superficial resemblance to the Afrotropical C. maculatus , but differs in the reduced number of ventral head hairs, less clearly defined pale spots on the gaster and generally smaller size. The old record of Camponotus maculatus for Socotra (Kohl 1907), based on specimens collected in 1899 by the expedition of the Vienna museum, should certainly be referred to C. hova . Small workers of C. atlantis and C. hova may be uniformly pale and difficult to distinguish, but the spines on the hind tibiae of C. hova are absent in C. atlantis (Figs 17-18). In addition, large workers of C. atlantis usually lack the two to six suberect hairs present on the underside of the head in C. hova . As the largest ants present on Socotra, a separate name for C. hova and C. atlantis - "kazer" - is used in the native language.
