ABSTRACT

Introduction. The genus Latrodectus (Family Theridiidae) includes medically important spider species in the American Continent; including L. mactans commonly known as the black widow or capulina.
Objective. To report for the fi rst time the presence of medically important spiders of the genus Latrodectus in Yucatan.
Materials and methods. Spider specimens from fi eld collections and deposited in the Collection of the Entomology Laboratory (UADY) were identifi ed, described and photographed.
Results. Four specimens of Latrodectus were identified: Latrodectus mactans (Fabricius, 1775) (black widow) and Latrodectus geometricus C. L. Koch, 1841 (brown widow). Material examined: Latrodectus mactans 2♀, Rancho Hobonil, Tzucacab, Yucatán, 13 September 2011, J. Castañeda-Gómez; Latrodectus geometricus 1♀, Col. Centro Mérida, Yucatán, December 2007; Latrodectus geometricus 1♀ X´matkuil, Yucatán, 10 September 2009, C. Arisqueta-Chablé.
Conclusions. The recognition of medically important spiders, particularly L. mactans in Yucatan, and the pathology associated to their bite are important factors for a correct diagnosis and proper treatment of spider bites.
