New Species of Giant Spider Announced

As reported in the scientific journal Zootaxa, this spider also represents a newly discovered genus.

Allow me introduce you to Califorctenus cacachilensis (Cteninae, Ctenidae, Araneae), the giant spider of the Sierra Cacachilas.

OK, the arachnid in question measures about four inches across, with a body about one inch long. But compared to most spiders in the world, that qualifies as a giant to scientists. And it would seem that way to most anyone who felt one running up their leg, or had an encounter with its furry fangs.

In fact, this new species of wandering spider is reminiscent of the infamous Brazilian wandering spider, among the most venomous arachnids in the world. Also known as the banana spider, newspaper reports of my childhood wherein Brazilian wandering spiders hitchhiked to the USA amongst banana bunches, made me extremely wary of my mother’s grocery bags.

However, you would have go to the mountain caves at the extreme tip of Baja California to find this new creepy crawler, as that is where they were discovered, doing their wandering in the dark of night, in search of prey. But one reason this new spider has been declared the first species of a newly discovered genus is that it is not as venomous as its poisonous cousins from points father south.

While new species of spiders and insects are discovered all the time, it is rare for anything so conspicuously large to be found new to science these days.
