Abstract
Information is presented on taxonomie traits of Callistochiton pulchellus (Gray, 1828) collected at thirteen sites between Iquique (20°12'S- 70°09'W) and Pabellón de Pica (20°54'S-70°08'W) in die north of Chile. Sampling sites were at least one km apart. The species was found at only three of the thirteen sampling sites (23%), and only underneath boulders sunken in sand. A new southern limit for this species was recorded in Chanavayita, 54 km south of Iquique. The most important characteristics of its habitat are presently discussed, as well as the the most relevant morphological differences of this species in comparison with Calloplax vivípara (Plate, 1902) which it closely resembles in form and tegmental ornamentation. C. pulchellus had a greater number of radial lines on the cephalic plate (2) than C. vivípara (9). It was also noted that the central plates in the former species were more rectangular than those of the latter species.
