Folding-door Spider - Antrodiaetus unicolor

Folding-door Spider - Antrodiaetus unicolor
Rome, Floyd County, Georgia, USA
December 20, 2008
A Folding-door Spider of the Genus Antrodiaetus. It could be either A. unicolor or A. microunicolor, but I think placing it under A. unicolor will be fine until I can examine more specimens and arrive at a more conclusive ID. At any rate, this should make a neat addition to the Guide since there are currently no images of Antrodiaetus from Georgia (or the entire Southeast, for that matter). Indeed, this Genus of Mygalomorph seems to be particulary rare here - at least in comparison to the more common Myrmekiaphila and Cyclocosmia that dominate our area. I dug this specimen from its burrow, which was located on the slope of a very steep ravine that drains into Dykes Creek. I'm not yet sure what gender it is, or whether or not it is even an adult. I assume it's an immature simply on the basis of its small size. There seemed to be a healthy population of Antrodiaetus within this small area, but it appeared that only the immatures were active at the time (i.e., had their burrows open at night).
