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, Uruguay and Argentina.[2] 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, and have unusually long slender pedipalps. The females are dark brown or black and more compact. Both sexes may grow to be roughly 2 inches (5.1 cm) across (legs extended), with the males typically having longer legs, and the females often having larger, bulbous bodies. The abdomen of the southern house spider is covered with fine velvety light gray hair.
Female southern house spiders are rarely seen, as they build radial webs around crevices, for which reason their family (Filistatidae) is called crevice weavers. Females seldom move except to capture prey caught in their webs. Males, on the other hand, typically wander in search of insects and females to mate with, having no particular territory.
The southern house spider is a cribellate spider. That is, its spinnerets do not produce adhesive webbing. Instead, to capture prey the spider uses its legs to comb webbing across its cribellum, a spiked plate near the spinnerets. This combing action frays and tangles the strands, producing a fine, velcro-like netting that ensnares insect legs.
Male southern house spiders sometimes appear aggressive, but they do not bite unless trapped, and their mouthparts are too small to easily penetrate human skin. They do, however, have an unnerving tendency to crawl across anything in their path regardless of whether it is alive. This is not aggression; these spiders are simply nearly blind and cannot see larger animals. Indeed, these spiders instinctively play dead if they feel threatened (a tactic which is effective against their common predators).
Southern house spiders are capable of crawling through crevices as narrow as 1/4 in (0.66 cm) due to their elongated bodies and compact legs.
The southern house spider mating ritual is a lengthy (over an hour) and elaborate process with long periods during which neither the male nor the female moves considerably. When the wandering male encounters a female's web, there may be an initial confrontation where each scares the other. Upon recovering, the male then constructs a large web around the female's crevice. When this web is complete, the male pulls on its strands continuously to draw the female out of her hole, which may take several minutes. Following her emergence, each spider will tap at the other in an effort to grasp the other by the forelegs, with the male remaining suspended in his web.

Kukulcania hibernalis es una especie sinantrópica de arácnidos que se encuentra Argentina, Brasil, Chile, Colombia, Paraguay y Uruguay. [1]
Esta especie había sido considerada como parte del género Filistata, pero ahora está considerada en el género Kukulcania. Las arañas de la familia Filistatidae están más frecuentemente asociadas con otras familias que tienen una estructura llamada “cribellum” (una “placa” productora de seda que se encuentra más al interior).
Kukulcania hibernalis es una especie que presenta un alto grado de dimorfismo sexual. Las hembras son negro-grisáceas y de 3 a 3.5 cm. de longitud corporal. El abdomen es “alongado-ovoidal”, y a veces se le puede ser considerablemente distendido, en caso de haberse alimentado o que la hembra esté preñada. El macho mide entre 9 y 10mm de longitud, es de color beige o ámbar y tiene patas largas y pedipalpos. Los machos también tienen una cinta café desde la parte trasera de los ojos y và disminuyendo hasta terminar la caja torácica. Así mismo, los machos de K. hibernalis son generalmente más largos que L. reclusa. Tienen patas más largas y pedipalpos más largos, y tienen 8 ojos agrupados en una prominencia, en comparación con los seis ojos (es tres pares) de la L. reclusa.
A La Kukulcania hibernalis le gustan los espacios cerrados especialmente oscuros, las esquinas de las ventanas, el espacio entre las puertas, cajas y demás escondrijos. Las hembras y los ejemplares jóvenes tejen telarañas especializadas que son encontradas principalmente en casas, puentes o cualquier estructura de manufactura humana. Su telaraña es muy distintiva. Bajo el microscopio la seda de su telaraña parecería lanosa, esto por la acción del calamistrum que empuja la seda desde el. Esta seda tiene partes más gruesas y pegajosas que son características de otras especies de arañas. Esto, junto con la forma característica de su red ayuda a la captura de sus presas. Los machos no construyen redes, en vez de eso, vagan en búsqueda de hembras para aparearse. Las hembras ponen un número aproximado de 200 huevos que son puestos en una bola de seda de unos 15 mm de diámetro y son cuidados dentro del nido. Las hembras pueden vivir hasta 8 años.
Esta especie es totalmente inofensiva, se le considera beneficiosa ya que captura insectos considerados como pestes como moscas, cucarachas, y hasta escarabajos.
Identificaciòn:
Su distintiva telaraña las hace de fácil identificación. La protuberancia en donde se localizan los ojos, el tamaño y color en ambos sexos, el tamaño de patas y pedipalpos los hacen de fácil identificación. Los machos son fácilmente capturados en exteriores y las hembras se les ve en las afueras de su nido.
Manejo: Estas arañas se localizan en o a los alrededores de las casas o edificios porque sus presas son atraídas por las luces de los hogares. Para prevenir infestaciones de estas arañas se recomienda limpiar y/o reparar las bases de las ventanas, así mismo los espacios sobre y debajo de las puertas deben ser sellados, reparar los hoyos en las paredes y la constante limpieza de los rincones en nuestro hogar, evitará en mayor medida que se alojen en nuestra casa.
