Male epiproct. Apical segment of upper limb ca. 283 μm long, and armed on the apical ca. 225 μm with dense patch of wave-like spikes ( Figs. 115-117, 119 ); apical segment ca. 126 μm wide at base, swollen to ca. 165 μm at midlength and tapered to a narrowly rounded tip. Basal segment of upper limb ca. 350 μm long and ca. 94 μm wide near midlength; basal segment bears a median groove which extends to apical segment base. Greatest width of lower limb ca. 190 μm; lateral margins of lower limb bearing a sparse row of long setae near apical spoon.

Male tergal process. Prominent raised structures on abdominal terga 7-8 ( Figs. 118-120 ); posterior process on tergum 8 trilobed and ca. 152 μm wide; median lobe much smaller than lateral lobes, but all covered with scale-like structures; notch ca. 45 μm wide. Anterior process of tergum 8 slightly notched on dorsal margin, covered with scale-like structures, and ca. 132 μm wide. Process on tergum 7 bilobed, ca. 25 μm wide and covered with scale- like structures.
