摘要：Using pitfall traps, the species composition and abundance of solpugids were studied in several ecotopes ofChile’s transitional coastal desert. The study was conducted in the area around Punta de Choros (29º15’S, 71º26’W)and in Los Choros Archipelago (29º32’S, 67º61’W), in 2005 and 2006. Five species were recorded: Procleobis sp.;Sedna pirata Muma, 1971 (Ammotrechidae); Mummucia sp.; Mummucia variegata (Gervais, 1849) (Mummuciidae);and Ammotrechelis goetschi Roewer, 1934 (Daesiidae). Solpugid abundance was higher on the continent (65%) thanon the islands (35%). The ANOSIM used to evaluate any difference in species richness between ecotopes revealed nosignificant differences (R= 0.097, p= 0.13). The similarity dendrogram obtained from the Bray-Curtis matrix indicatesthat there are 3 groups of ecotopes: steppe, dune, and a miscellaneous group. From the data it is inferred that thediversity and abundance of solpugids in the ecotopes studied may be related to plant structure and to the pedologicalconditions of the habitat.
