Biologists at San Diego State have discovered a new spider species in the caves and canyons of the southern Sierras. The Hypochilus xomote is a small, long-legged creature that’s black and gray — and old.
The Hypochilus xomote is a newly discovered species of spider that's native to the rocky landscapes of the southern Sierra Nevada, as seen here in an undated photograph.
You would find it in the cool, rocky canyons and caves of the southern Sierra Nevada mountains, not far from Bakersfield. Hedin and a biology master’s student were examining specimens in that region, in search of spiders from the Hypochilus genus. They knew the Hypochilus xomote “That’s called morphological stasis and the lineage goes back maybe 60, 80, maybe 100 million years,” he said. “Through that kind of expanse of time, the morphology has stayed in the same place, so it’s very much like a living fossil.”
Hedin said it’s too early to know whether his spider is endangered. He does say that the spider has a naturally small geographic habitat. It’s not threatened by development in its rural landscape, but it could be threatened by fire and climate change.
