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 midlength; 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 ). Trilobed 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.
