Limnesia (Limnesia) arevaloi arevaloi K. Viets, 1918

Limnesia martianezi Lundblad, 1962 — nov. syn.

Material examined. Holotype female, SMNH 6013, Tenerife, spring Martiánez 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 (1962a) 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.
