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.
