Arthrorhabdus, from the Greek ἄρθρον, a joint, and ῥάβδος, a staff, is a genus of Scolopendrid centipede in the subfamily Scolopendrinae.[1][2][3][4] Species are found in Mexico and the Southern United States (A. pygmaeus), Australia (A. paucispinus & A. mjöbergi), and South Africa (A. formosus).[5][6] Since a reapprasial in the genus in 2010, the genus only has four species.[3][6] It may be polyphyletic.[2][6]

Identification and morphology

Arthrorhabdus species bear several morphological similarities to those of the genus Cormocephalus: their spiracles,[7] eyes, and mouthparts are the same.[1] It also resembles members of the genera Scolopendra and Asanada, but can be differentiated from other genera by a variety of characteristics, specifically the head not overlapping the first tergite,[6][1] additionally from Scolopendra by the shape of the mouthparts and spiracles,[6] and further from Cormocephalus by morphological features on the legs.[1]

Arthrorhabdus species have between 18 and 26 antennomeres (antennae segments).[6]
