Researchers Discover New Species of Giant Spider (mentalfloss.com)
adeelarshad82 writes: Califorctenus cacachilensis, recently named by researchers at the San Diego Natural History Museum, was first located in 2013 in a mountain range in Baja California Sur, Mexico. The eye pattern led researchers to believe it was potentially part of a group of wandering spiders from the Ctenidae family. Knowing Ctenidae are nocturnal, the researchers returned to the cave at night, where they spotted a living specimen. Their research further led them to confirm that it was a previously unidentified species related to the Brazilian wandering spider. The findings have been published in Zootaxa.
a lot more than they thought
Pacific North West already have giant house spiders that appear inside at the end of summer. Even fairly modern houses that shouldn't have any gaps big enough for them to sneak in through, there they are perched on the wall in the morning waiting for the vacuum cleaner to find them.
