Tarantulas, frequently featured in campy horror movies like "Kingdom of the Spiders," star in a new study that reclassified dozens of tarantula species and described 14 new ones living in deserts, mountains, and backyard habitats in the southwestern U.S. Get acquainted with several of these charismatic spiders, in photos. [Read the full story about the new tarantula species]

Aphonopelma eutylenum

Aphonopelma is a genus of tarantulas that includes nearly all species found in North America. A. eutylenum was originally described in 1940 and is found in California, west of the Mojave Desert. (Credit: Chris Hamilton)


Aphonopelma hentzi

Discovered in 1852, A. hentzi is the most widely distributed species in the United States, found in Missouri, Arkansas, Louisiana, Kansas, Oklahoma, Texas, Colorado, New Mexico and Arizona. (Credit: Brent Hendrixson)


Aphonopelma saguaro

One of the new species described in the study, A. saguaro was named for Saguaro National Park, where this species can be found in the foothills of the Santa Catalina and Rincon Mountains. (Credit: Chris Hamilton)


Aphonopelma steindachneri

First described in 1875, Aphonopelma steindachneri is widely distributed across Southern California and is very common. The species is likely not endangered or threatened, though some populations in urban areas could be affected by human encroachment and development. (Credit: Chris Hamilton)


Aphonopelma moderatum

Aphonopelma moderatum is widely distributed in Texas counties bordering the Rio Grande. In areas with shallow soils, spiders have been found under large flat rocks. (Credit: Brent Hendrixson)

Home, home on the plains

A habitat of Aphonopelma johnnycashi, one of the 14 new tarantula species described in the new study. Named for singer Johnny Cash, the spider was abundant near Folsom State Prison in California, which inspired Cash's song "Folsom Prison Blues," and the tarantula's dark coloration reminded the study's lead author of Cash's preference for head-to-toe black wardrobe. (Credit: Chris Hamilton)


A beautiful locale

Aphonopelma superstitionense and Aphonopelma chalcodes habitat. A. superstitionense appears to have a limited distribution restricted to the foothills near the Superstition Mountains in Arizona. These tiny tarantulas are probably common but are difficult to find, as they are only active for a brief period during the year and their burrows are well hidden. A. chalcodes is widely distributed across the southern two-thirds of Arizona. (Credit: Chris Hamilton)


Home sweet home
