sorely need a complete revision, as what follows attest. The key characteristic is aptery in sexuals: in early spring, small males were present in a nest at Arenas Blancas, running very rapidly. Its apterous aspect, suggested at first a social parasite. Thereafter, as all queens from El Hierro showed also to be apterous, their true nature was evident. Sexuals are not ergatoid: but for the lack of wings they have the characteristic male and gyne morphology. At Pie del Risco, one fully winged male was collected. This is the first free-living formicine ant in which wingless males have been noted. After checking material from other islands, it was soon clear that this is best interpreted as a case of wing polymorphism: in queens from the islands of Gran Canaria and La Gomera there is a variable degree of thoracic simplification, from a complete winged thorax to an apterous morphology, lacking tegulae and with a fused scutum and scutellum. An enhanced pilosity in pronotum and scutellum seems to be correlated with thorax simplification.

) although this is probably related with the parasitic life of both species. It is legitimate to speculate on wing loss though none of the hypotheses exposed in Wagner & Liebherr (1992) seems to apply in this case. Habitat stability is not applicable because of the recent volcanic eruptions and large-scale landslides at El Hierro (Gee et al., 2001). Habitat isolation neither seems to be appropriate as the numerous sites where this species has been collected attest. The energetic cost of flight is also to be rejected: El Hierro has not a cold climate and, even if the prevailing trade winds, from the Southwest are high, this admittedly ad-hoc explanation is invalidated by the fact that the similarly sized males and females of
