Taracus marchingtoni
Taracus marchingtoni is a genus of harvestman found in the lava caves of semi-arid and arid regions of central Oregon.[1] It belongs to the family Taracidae and was first collected by Jean and Wilton Ivie in 1965 in Lava River Cave but not identified as a new species until collected by Neil Marchington of the Oregon High Desert Grotto in 2008.[1][2] Its range is suspected to be the surrounding areas of Newberry Volcano.[1] It has enlarged but thin chelicerae, typically equal to or longer than the entire length of the body, and in small-bodied males nearly three times as long.[1] The harvestman is troglobiotic and has a predominantly white abdomen, black chelicerae, and highly reduced eye size.[1] T. marchingtoni has been observed feeding on small troglophilic millipedes identified as Plumatyla humerosa of the Conotylidae family.[1]
