A new species of Tridactylogonus Jeekel, 1982 from South Australia (Diplopoda, Polydesmida, Paradoxosomatidae)

is described from Warrenben Conservation Park at the southern end of the Yorke Peninsula in South Australia. Like Jeekel, 1982 and Jeekel, 2002, the new species has prominent cellular sculpturing on the prozonites and granulose sculpturing on parts of the metazonites. Unlike its congeners and most species in the subfamily Australiosomatinae, the new species lacks a femoral process or tubercle on male leg 1.
