The twoPseudomyrmex species studied have the following communication systems: a) P. triplarinus informs its nestmates about the presence of food, but not about its location.P. termitarius does neither. b) Both species recognize their territory and/or area around the nest entrance through odours on the substrate.P. triplarinus marks its territory with a pheromone from the thorax, probably from the metapleural gland. This territorial mark lasts less than 1 h, and probably advertises at least part of the home range of the colony. The territorial odour used byP. termitarius, probably works as a nest entrance orientation mark, and lasts over 5 h, but less than 24 h. The origin of the odour is not clear. c) P. triplarinus uses a cephalic pheromone as the main signal for nestmate recognition.P. termitarius uses non-identified odours, present on all body parts of the insect, as a nestmate recognition signal. d) Both species produce alarm pheromones from the head and the gaster. The communication systems are interpreted in relation to the ecological adaptations of each species.
