Ityphilus is a genus of centipedes in the clade Ballophilidae. It was described by American myriapodologist Orator Fuller Cook in 1899.^[1]^[2] Centipedes in this genus feature distinctly club-like antennae, well marked sclerotized lines on the forcipular coxosternite, and two pores on each coxopleuron.^[3] These centipedes range from about 1 cm to about 9 cm in length and have 37 to 113 pairs of legs.^[3]^[4] The miniature species Ityphilus grismadoi ranges from 7 to 9 mm in length and can have as few as 37 leg pairs, the minimum number found in this genus.^[4] The large species I. grandis can reach 93 mm in length and have as many as 113 leg pairs, the maximum number found in the clade Ballophilidae.^[5]
