Microhexura montivaga : ウィキペディア英語版 | Spruce-fir moss spider
The Spruce-fir moss spider, ''Microhexura montivaga'', is an endangered species of spider found at high elevations in the southern Appalachian Mountains. First identified in 1923, they inhabit moss that grows on rocks underneath the forest canopy. ==Description== This is one of the smallest mygalomorph spiders, with adults only measuring 3 to 4 mm. The coloration varies from light brown to yellow-brown to a darker reddish brown, with no markings on its abdomen. Their chelicerae project forward, and one pair of spinnerets is very long. They possess a second pair of book lungs, which appear as light patches behind the genital furrow.〔US Fish & Wildlife Service〕
