Camponotus guanchus Santschi 1908

Investigated was 1 type worker labeled ‘Type’, ‘Tenerife Valle Gimenes 10. IX. 1899.’, ‘ C. lateralis Ol guancha Sant’ and 1 type gyne labeled ‘Type’, ‘Tenerife Bajan..do 23: III: 1902’, ‘ C. lateralis guancha Sant’; both stored in NHM Basel. This species from the Canaries differs from all Eurocaucasian species shown in Tab. 2 and Tab. 3 by propodeal and petiolar shape. The dorsal surface of propodeum is clearly convex in transverse section. In lateral aspect, dorsum and caudal slope of propodeum form an angle of about 130°and the transition is rounded – i.e., there is no indication of a dorsocaudal protrusion or of an abrupt transition from dorsal plane to slope. The petiolar node is narrow (PeW/CS 1.25 0.322) but thick in lateral view – corresponding to the situation in Lasius fuliginosus (Latreille 1798) . These characters may possibly indicate a close relatedness to the North African taxa C. sicheli rubra Karavajev 1912 and C. sicheli nigra Karavajev 1912 .
