Ityphilus

Ityphilus is a genus of centipedes in the clade Ballophilidae. It was described by American myriapodologist Orator Fuller Cook in 1899. Centipedes in this genus feature distinctly club-like antennae, well marked sclerotized lines on the forcipular coxosternite, and two pores on each coxopleuron. These centipedes range from about 1 cm to about 9 cm in length and have 41 to 113 pairs of legs. The dwarf species Ityphilus donatellae ranges from 8.5 to 11 mm in length and can have as few as 41 leg pairs (41 in males, 43 in females), the minimum number found in this genus. 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.
