Hypopygium ( Fig. 1 View FIGURES 1 – 4. 1 ): Anal tergite with well developed lateral teeth and 7 setae in 2 groups on medial area; each group of 3 or 4 setae. Anal tergite bands Vshaped, narrowly separated in middle, ending by median tergite setae. Anal point broad, 28 µm long, with pair of long anal crests and 7 basal setae, 2 on anal crests and 2 or 3 laterally. Phallapodeme 70 µm long. Transverse sternapodeme 34 µm long, with oral projections. Gonocoxite 124 µm long. Superior volsella roughly square, anterior and median margin concave, with 3 or 4 dorsal and 3 inner surface setae, and 1 seta at base arising on ventral side. Digitus crooked near middle and tapered to pointed apex. Median volsella 40 µm long, lateral margin without lamellae, inner margin with about 4–6 lamellae and apical half with bundles of lamellae at 90º to stem of volsella. Inferior volsella 80 µm long, distal part divided into 2 rounded lobes and with about 13 apical setae. Gonostylus 130 µm long. HR 0.95; HV 2.52.
