The amphora -group T9 strongly reduced, in preparations often barely perceptible. The anteriorly truncate penis resembles an amphora, with handles formed by the abruptly outcurving parameroids (e.g., Figs. 83, 85: pb). The trigonium is basally wide, then restricted to a long bottleneck, the tip mostly again wider. The flat band-like parameroids are shorter than the apparently rigid trigonium which is not visibly articulated with the pala. There is a bracket-like transverse sclerite of uncertain homology, possibly the tegmen. The parameres are independent from it, separate, each with a basal rod and a caudal plate of variable form, armed with spines. Females (known only of N. armstrongi): S7 with two areas with micropores and fine canals (Fig. 89). The apodemes of S8 are anteriorly connected by a ring (not shown). Prehensor with two large strongly spinose sclerites (Fig. 90). The few species live in the southeast of Australia and were rarely collected.
