Description, n=10.

Slide-mounted adult female 939-1542 μm long (Holotype 1130 μm long), body outline oval. Pygidium with 1 pair of lobes; median lobes small, zygotic, parallel, lobes connected via narrow sclerosis, each lobe wider than long, rounded; margin between lobes not incised. Gland spines 9-24 μm long, ca. 1-2 × as long as median lobes, 1 gland spine on lateral margin of each pygidial segment; pair of setae between median lobes. Marginal ducts: 1 on abdominal segment 7, ca. 4 on segment 6, ca. 3 on segment 5. Dorsal ducts smaller than marginal ducts; present in clusters (i.e. less organized than rows); 4-6 submedial ducts present on segment 6; 5-7 marginal-submarginal and ca. 9 submedial ducts on segment 5. Perivulvar pores: 3-4 posteromedial, 10-19 posterolateral, 13-27 posterior, 0-4 anteromedial, and 1-8 anterolateral. Trilocular pores in cluster of 2-5 near anterior spiracle; absent near posterior spiracle. Microducts numerous on dorsal surface of head, scattered on ventral surface of thorax and abdomen. Antenna with 2 fleshy setae.

Comments.

Poliaspis wilga is the only species of Poliaspis to have only the median lobes present. It can also be recognized by the loose groupings of more than 2 marginal ducts on abdominal segments 6 and 7.
