dc.description.abstract Filistatidae is one of the most phylogenetically enigmatic spider groups, and the genus Kukulcania Lehtinen includes the commonest representatives of the family. Its type species, K. hibernalis (Hentz, 1842), remains a favorite candidate for studies on spider phylogeny and comparative morphology. However, little is known about the taxonomy, species limits, and distribution of its closest relatives, because no generic revision has ever been undertaken. We present the first comprehensive assessment of the taxonomy of Kukulcania. The species K. hibernalis, K. arizonica (Chamberlin and Ivie, 1935), K. utahana (Chamberlin and Ivie, 1935), K. hurca (Chamberlin and Ivie, 1942), K. brignolii (Alayón, 1981) comb. nov. (transferred here from Filistata Latreille), K. tractans (O. Pickard-Cambridge, 1896), and K. geophila (Chamberlin and Ivie, 1935) are redescribed based on our examination of type material. We show that the name Filistata brevipes Keyserling, 1883, which had previously been placed in Kukulcania, actually belongs to a prithine spider, and propose the new combination Pikelinia brevipes (Keyserling, 1883). Filistata geophila wawona Chamberlin and Ivie, 1942, is newly synonymized with Kukulcania geophila. Eight new species of Kukulcania are described: K. cochimi, sp. nov. (from Baja California), K. gertschi, sp. nov. (northern Mexico), K. mexicana, sp. nov. (central Mexico), K. santosi, sp. nov. (southern Mexico to northern South America; previously misidentified as K. brevipes), K. tequila, sp. nov. (western Mexico), K. chingona, sp. nov. (western Mexico), K. benita, sp. nov. (endemic to the San Benito Islands in Baja California) and K. bajacali, sp. nov. (Baja California). With this, the number of recognized species in the genus is increased to 15. All species have their distributions mapped and both sexes illustrated. The first identification key to the genus is presented. A study on the morphology of the genus is undertaken using light and scanning electron microscopy, and the phylogenetic position of Kukulcania within the Filistatinae is briefly discussed. A novel putative synapomorphy for the subfamily is proposed. en_US

  • Bulletin of the American Museum of Natural History
    The Bulletin, published continuously since 1881, consists of longer monographic volumes in the field of natural sciences relating to zoology, paleontology, and geology. Current numbers are published at irregular intervals. The Bulletin was originally a place to publish short papers, while longer works appeared in the Memoirs. However, in the 1920s, the Memoirs ceased and the Bulletin series began publishing longer papers. A new series, the Novitates , published short papers describing new forms.
