Black Widow sp. 1

Black Widow sp. 1, Latrodectus sp.
TX: Presidio Co., Chinati Mountains, San Antonio Canyon, overnight under halogen light set, 9-10 September 2005

This individual was found completely within the range of the Western Black Widow, Latrodectus hesperus -- no other Black Widow should naturally occur there. However, its markings are fully consistent with the Northern Black Widow, Latrodectus variolus, and since this one was at a bunkhouse, the possibility of introduction by man has to be considered.
