Diagnosis. Small polydesmidans with head plus 19 or 20 rings; head and telson facing downwards; metatergites with numerous tubercles varying in size and arrangement. Tergite 2 notably enlarged and extended anterolaterally, with large tubercles along its edges. Segments 3–19/20 lacking paranota, but pseudo-paranota may be formed by metatergal tubercles above leg bases. This genus differs from other haplodesmids mainly in its gonopod configuration: gonopods without cannula or prostatic groove; telopodite bends sharply midway along its length. Proximal portion of telopodite sub-cylindrical with an apical tab before the bend. Three apical setae grouped below apical tab. Distal portion of the telopodite with two branches directed posterobasally or laterobasally, which may be further subdivided into lobes or branches.

Distribution: Australia, New Caledonia, and Jamaica.
