Evolución de la Tricobotriotaxia durante el desarrollo de tres Salticidae neotropicales (Araneae)

Descripción
Sumario:[EN] Recordings of the trichobothrial pattern during ontogeny of Metaphidippus odiosus (Peckham & Peckham, 1901), Bryantella smaragdus (Crane, 1945) and Dendryphantes patagonicus Simon, 1905 were carried out from specimens bred in the laboratory. Such patterns were found stable at the specific level. In the three species, males and females show differences in the tibial territories which enable to determine the sex of an immature since early stages of development; in Metaphidippus odiosas and Dendryphantes patagonicus the lateral territories are present in different legs for each sex; males of Bryantella smaragdus have an intercalar trichobothrium in the anterior territory of leg IV which is absent in females. Interspecific comparison demonstrated that the three species have identical trichobothrial territories with aproximately the same number of sensilla in each one.
