Male epiproct. Apical segment of upper limb ca. 265 - 277 µm long, armed on apical ca. 152 - 172 µm with dense patch of wave-like spikes (Figs. 49 - 52); apical segment ca. 100 - 106 µm wide at base, tapered to a narrow rounded tip. Basal segment of upper limb ca. 257 µm long and ca. 65 - 67 µm wide at mid-length; basal segment with a broad, shallow, median groove. Greatest width of lower limb ca. 176 - 187 µm; lower limb bears a sparse, marginal row of long setae in apical third (Fig. 49). Male tergal process. Prominent raised structures on abdominal terga 7 and 8 (Figs. 53 - 54). Tri-lobed process of tergum 8 ca. 140 - 146 µm wide and bearing a broad, shallow median notch, interrupted by median projection. Lobes of process covered with scale-like structures; anterior face of process bears a deep transverse groove (Fig. 53). In lateral aspect, lobes extend vertically as thin discs set on narrow bases. Process of tergum 7 ca. 100 µm wide; similar in structure to 8 th tergal process.
