The Barack Obama trapdoor spider (Aptostichus barackobamai) is a species of spider in the family Euctenizidae named after the 44th President of the United States, Barack Obama. The species was first reported by Professor Jason Bond of Auburn University in December 2012 as one of 33 new species of the genus Aptostichus.[1]

Distribution

A. barackobamai is a species endemic to California,[1] and has been observed at several locations in the northern part of the state. Particular locations where populations are known to exist are Mendocino, Napa, Shasta, Sutter, and Tehama counties.[2]

Conservation status

Due to the wide range and abundance of A. barackobamai, the species is not considered to be a threatened species overall, though some isolated populations (such as those local to the Sutter Buttes) may be vulnerable.[2]

Distribution

provided by Zookeys
Distributed widely throughout north-central California with populations known from Mendocino, Napa, Shasta, Sutter, and Tehama Counties (Map 18). Aptostichus barackobamai has been collected in the Mayacamas Mountains in the west, Sutter Butte in the Central Valley, and the ridges to the north ringing the northernmost extension of the Central Valley. The DM (Map 19) indicates that the species is likely to be more widely distributed throughout the region and should occur further to the south along the Central Valley eastern ranges. The primary habitat type is mixed redwood and coniferous forest. Males have been collected in August, September, and December.
