Abstract

MAYA-MORALES, Julieta; JIMENEZ, María Luisa  and  MORRONE, Juan J.. Track analysis of the funnel-web spiders (Araneae: Agelenidae) of Mexico. Rev. Mex. Biodiv. [online]. 2018, vol.89, n.2, pp.530-540. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2018.2.2367.

We analyzed distributional data of 59 species of funnel-web spiders (Araneae: Agelenidae) of Mexico. We constructed individual tracks for the species analyzed, based on published and unpublished records, and based on their overlap we obtained 9 generalized tracks. Three generalized tracks belong to the Californian Nearctic dominion (Nearctic region) and 6 generalized tracks extend along the Mexican transition zone. Seven generalized tracks are defined by species of the same genus or closely related genera and 2 generalized tracks are supported by species of distantly related genera, which shows that both spatial relationships and phylogenetic evidence support the existence of ancestral biotas including unrelated taxa.

Keywords : Biogeography; Mexican transition zone; Ageleninae.
