Tetramorium depressum Espadaler, 2007, new status

15. Tetramorium depressum Forel (new status)

(3, w; 4, w; 9, w; 11, w; 13, w; 14, w; 22, w; 26, w; 27, w; 30, w; 33, w; 39, w; 40, w; 41, w). Forel ((1892) described this ant as a subspecies of T. semilaeve Andre. In addition to the head surface differences already noted by Forel, both taxa have different male genitalia and head worker sculpture and are here formally proposed as distinct species. From 20 to 1300 m although big, populous nests are found at the higher altitudes, usually under stones. The few nests located in the drier coast seemed to be in a miserable and suffering state, with a small number of workers. But for a smaller size the morphology of lowland populations was indistinguishable from other populations.
