Taracus marchingtoni
Taracus marchingtoni is a troglobiotic harvestman species endemic to lava caves in central Oregon. First collected in 1965 but not formally described until 2016, it exhibits classic cave-adapted traits including reduced eyes and depigmentation. The species is notable for its extremely elongated chelicerae, which in males can exceed body length. It has been documented feeding on troglophilic millipedes.
