Limnesia (Limnesia) arevaloi subsp. arevaloi K. Viets 1918

Limnesia (Limnesia) arevaloi arevaloi K. Viets, 1918 Limnesia martianezi Lundblad, 1962 ��� nov. syn. Material examined. Holotype female, SMNH 6013, Tenerife, spring Marti��nez near Puerto de la Cruz, Lundblad 24.04. 1960. La Gomera, Cedro u. Caseria, kl. Saltadero, Moos, 11.09. 1992 Beyer coll. (1 / 1 /0). In the original description, Lundblad (1962 a) compared this species only with L. atlantica Lundblad, 1942 from Madeira. He proposed as a diagnostic difference to that species the insertion of the ventral peg-like seta on P- 2 on a short socket, and a more slender shape of the gnathosoma and chelicera. All these character states are equally found in L. arevaloi, a species in good agreement also with regard to the variability of idiosoma and appendage measurements (Gerecke 1991). Under all morphological aspects there is no doubt that L. martianezi is a junior synonym of L. arevaloi. On the Canary islands, the presence of the latter (sub)species (characterized by immovable genital flaps in the male sex) is now confirmed also by the new records from Gomera.
