Tergite 8 transverse and truncate apically and slightly concave medially (Fig. 86). Sternite 8 elongate and slightly produced posteriorly (Fig. 87). Median lobe of aedeagus with narrowly produced and sinuate apical part of tubus in lateral view (Fig. 83), sides swollen in dorsal view; bulbus moderately large (Fig. 84); internal sac with structures as illustrated (Figs 83, 84). <b>Female</b>.

Some CNC specimens of this species bear his identification labels as <i>G. praeminosa</i> Ashe, 1987 [manuscript – unpublished name].
