The southern house spider is a species of large spider in the family Filistatidae. Currently given the scientific name Kukulcania hibernalis, it was formerly known as Filistata hibernalis. Found in the Americas, it exhibits strong sexual dimorphism. It is occurs in the southern states of the USA, throughout Central America and some of the Caribbean, to southern Brazil and Uruguay. The males may be mistaken for brown recluses because the two have similar coloration and body structure. However, compared to the brown recluse, male southern house spiders are typically larger in size, lack the distinctive violin shape on their cephalothorax.
