Geophilus

Geophilus is a genus of soil centipedes in the family Geophilidae[1] largely considered to be synonymous with Brachygeophilus.[2] It is a mostly holarctic genus characterized by a claw-shaped ultimate pretarsus, anterior porefields, complete or nearly complete coxo-pleural sutures at the prosternum, and incomplete chitin-lines.[3] The generic name first appeared in Brewster's Edinburgh Encyclopaedia in 1814 as Geophilus electricus.[4] Two species in this genus include centipedes with only 29 pairs of legs, the lowest number found in the family Geophilidae: G. persephones (29 pairs in the only specimen, a male) and G. richardi (29 or 31 pairs in the males and 33 pairs in the females).[5]
