Epiproct short, broad basally in dorsal aspect and bearing a small apical notch ( Fig. 1 View Figs ); apex bearing a cluster of ca. 4-8 spines giving apex a biserrate appearance in dorsal aspect; ventral sclerite bearing a double row of ca. 5 widely spaced, short spines ( Fig. 2 View Figs ). Cercal apices curved outward at tip forming a truncate, foot shaped structure ( Figs. 1, 3 View Figs ). Paraproct inner lobes slender and essentially parallel to one another, outer lobes large and triangular in outline; vesicle about 3 times long as wide ( Fig. 3 View Figs ).

Etymology. The name refers to the epiproct apex which in this species is notched and appears biserrate in dorsal aspect.

Diagnosis. The truncate cercal apices, biserrate epiproct apex and setal row on tergum 9 appear distinctive for this species which does not appear to be closely related to any known species.
