Apical segment of upper limb ca. 334- 370 μm long, armed over apical ca. 175-200 μm with dense patch of wave-like spikes (Figs. 43-45); apical segment ca. 131-134 μm wide at base, tapered to a narrow rounded tip. Basal segment of upper limb ca. 340-380 μm long and ca. 75-88 μm wide at midlength; basal segment with a broad, shallow groove extending from base to base of apical segment. Lower limb ca. 181-187 μm wide at point of greatest width, and bearing a sparse, irregular, setal row along apical third of lateral margins. Male tergal process. Prominent raised structure on abdominal tergum 8 (Figs. 46-48). Bilobed process ca. 213-230 μm wide, bearing a U-shaped notch ca. 84 μm wide. Lobes of process and posterior face of notch bearing scale-like surface structures; anterior face of process bearing a deep transverse groove (Fig. 47). In lateral aspect, lobes extend vertically at an approximate 90 ° angle from swollen base (Fig. 46).
