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 mid-length and tapered to a narrowly rounded tip. Basal segment of upper limb ca. 350 µm long and ca. 94 µm wide near mid-length; 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 tri-lobed 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.
