Geophilus anonyx
Geophilus anonyx is a species of soil centipede in the family Geophilidae[1] found in Oregon.[2] It was originally placed in the genus Brachygeophilus based on the lack of sternal pores, a character shared with the type species B. truncorum[3] (now Geophilus truncorum), however it was later moved to Geophilus.[2] DescriptionG. anonyx has 57 leg pairs and grows to a length of 24 millimeters. It's characterized by a prosternum lacking chitinous lines; dorsal plates distinctly bisulcate (cloven); spiracles all circular, last ventral plate narrow; coxal pores small, about a dozen on each side; anal pores present, distinct; and anal legs with tarsus biarticulate, without terminal claw.[4] Like G. tampophor, it differs from other western American geophilids by having prehensorial claws armed at the base, however unlike G. tampophor it possesses unarmed anal claws and a greater number of legs.[5] References
