Male epiproct (n = 10). Length 569-775 μm, width at midlength 88-100 μm, basal width 128-145 μm. Epiproct elongate, nearly parallel-sided for most of length beyond base. Dorsal sclerite longitudinally divided for entire length by a groove, wide at base and in apical third ( Figs. 37, 39-40 View Figs ). Epiproct recurved over abdomen in lateral aspect, its apical third lying between a pair of dorsal tubercles on the anterior margin of tergum 9 ( Fig. 38 View Figs ); posterior curved section with a short concave notch in dorsal margin. Epiproct apex may be everted partially (Figs. 43-44), completely ( Figs. 41-42 View Figs ), or not at all ( Figs. 37 View Figs , 49-53 View Figs ), to expose membranous spongy tissue.

Tergal process. (n = 8) A pair of conical processes located on the anteromedian margin of tergum 9, separated by the width of the epiproct ( Figs. 37-38, 40 View Figs , 43, 45)).

Vesicle (n = 1). Densely hairy over most of surface, outline almost circular, but with a short anterior pedicel (Figs. 47-48).

Female subgenital plate (n = 2). The plate is apically rounded and projects slightly beyond the posterior margin of sternum 8; lateral margins narrowed basally ( Fig. 35-36 View Figs ).

Larva. Undescribed.
