Southern House Spider (Kukulcania hibernalis) 072108

Southern House Spider (Kukulcania) female, Brandon N, NE TX 072108 dorsalThanks to Brandon N., from northeast Texas, for the first two photos in this set, and to Neal W., location not disclosed, for the last photo (page 3). All are of female southern house spiders (Kukulcania hibernalis, formerly Filistata hibernalis). This spider is a very common occupant of homes throughout the southern United States, where it makes crevice webs (see the cottony webbing it makes, as shown in the photo) in closets, utility rooms, and other dark places. The female is distinctive for its dark brown cephalothorax and abdomen, and the contrasting pale coxae and trochanters (the first two segments of each leg, which form the attachment to the cephalothorax). This spider is a member of the family Filistatidae. Filistatids are cribellate spiders, but differ from other cribellates by having fused chelicerae. The genus Kukulcania was first applied by Lehtinen, in 1967, to distinguish certain New World genera, Kukulcania among them, from other spiders that had previously been grouped under the genus Filistata. (see Ubick et al, [2005], pg. 104-5 for additional details).  NEXT PAGE ---- PAGE MENU:  1  *  2  *  3  *
