Leg spination (Fig. 2 K) fe: I pl 0-1-1 do 1-0-0; II do 1-0-0; III do 1-0-0; IV do 1-0-0; ti: I plv 1-1-1-1-1 rlv 1-1-1-1-1; II plv 1-1-1-1-1 rlv 1-1-1-1-1; IV pl 0-1-0 rl 0-1-0 plv 0-1-1 rlv 0-0-1; mt: I plv 1-1-1 rlv 1-1-1; II plv 1-1-1 rlv 1-1-1; IV rl 0-1-0 plv 0-1-0. Epigyne (Fig. 7 F) with small anterior hood, lighter median flat zone flanked by two large brown sclerotised areas, posterior part a sclerotised V-shaped groove. Vulva (Fig. 7 E) with very large anterior CO filled with dark material, globular posterior ST1 and small, globular, median ST2. Variability. In specimens from Cyprus and Lesbos, the posterior V-shaped groove of the epigyne is wider posteriorly and more parallel-sided. Etymology.The species epithet pheidoleicomes, "companion of Pheidole " refers to the myrmecophylic habits of the new species. Discussion. Arabelia pheidoleicomes sp. n. is clearly a myrmecophylic species. All specimens collected to date were found under stones, accompanied by yellow ants. The ants among which the specimens from Laerma (Rhodos) were collected, could be identified as Pheidole pallidula (Nylander, 1849), an ant species known for its associations with commensal arthropods such as Paussidae (Coleoptera) and Lepismatidae (Bernard 1968). In spite of repeated efforts by several collectors, no males could be found to date. An attempt to check material of the new species for the presence of bacterial endosymbionts influencing sex ratio (Goodacre et al. 2006), was inconclusive (S. Goodacre, personal communication). The investigation might be repeated in the near future. Distribution. Known from the Eastern Mediterranean islands Rhodos, Lesbos and Cyprus.
