Australiophilus longissimus is a species of centipede in the Zelanophilidae family.

It is endemic to Australia, and was first described in 1925 by German myriapodologist Karl Wilhelm Verhoeff.

[1][2] The original description of this species is based on a male specimen measuring 72 mm in length with 117 pairs of legs,[1] the maximum number of leg pairs recorded in the family Zelanophilidae.

[3] The species occurs in north-eastern coastal Queensland.

[2] The centipedes are solitary terrestrial predators that inhabit plant litter, soil and rotting wood.
