Prodelphic female gonad supplied with a postvulvar sac and to the left of midgut. Male gonads either paired (anterior outstretched testis to the left and posterior reflected testis to the right of midgut) or single anterior outstretched testis to the left of midgut. Spicules small, slightly bent, distally fused in one species ( A. unita ). Gubernaculum with small dorso­caudal apophysis or absent. Tail consists of proximal conical and distal cylindrical portions ending with terminal drop­shaped widening.
