Poliaspis ozothamnae Hardy & Henderson sp. n. Fig. 13

Material examined.

Holotype: female: Australia, QLD, Brisbane [-27.47, 153.02], ex Ozothamnus diosmifolius , 17.4.1986, N Gough (ANIC).

Paratypes: QLD. 6 adult females: same data as holotype (QDPI). SA. 7 adult females: Second Valley [-35.52, 138.22], ex Pulteneae involucrata , 13.10.1965, HM Brookes (ANIC).

Description, n=10.

Slide-mounted adult female 809-1256 μm long, body outline turbinate. Pygidium with 2 pairs of lobes; median lobes zygotic, parallel, close-set, lobes connected via narrow sclerosis, each lobe wider than long, apex obtuse-rounded and dentate; margin between lobes not incised; second lobe not bi-lobed, roughly pointed, apex notched in some specimens, close to medial lobe. Gland spines 8-17 μm long, about as long as median lobes, gland spine absent from margin of pygidial segment 7 (between medial and second lobes), 4-7 spines on margin of each of abdominal segments 5-6; pair of setae between median lobes. Marginal ducts: 1 on abdominal segment 7, 1 on segment 6, not differentiated from dorsal ducts on segment 5. Dorsal ducts present in clusters (i.e. several ducts across); ca. 5 submedial ducts present on segment 6; ca. 12 marginal-submarginal and ca. 12 submedial ducts on segment 5. Perivulvar pores: 3-6 posteromedial, 7-15 posterolateral, 10-18 posterior, 4-5 anteromedial, and 3-6 anterolateral. Trilocular pores in cluster of 7-16 near anterior spiracle; 2-8 near posterior spiracle. Microducts absent on dorsal surface of head, scattered on ventral surface of thorax and abdomen. Antenna with 1 fleshy seta. Gland tubercles absent from ventral surface of head anterior to anterior spiracle.

Comments.

Poliaspis ozothamnae is distinguishable from other species of Poliaspis by having (1) the second lobe close set to medial lobe, without a gland spine near lateral edge of medial lobe; (2) only 2 differentiated marginal ducts; (3) the 2-8 pores near each posterior spiracle; and (4) having multiple gland spines on each pygidial segment other than 8.

Etymology.

The species name is taken from the host name Ozothamnus diosmifolius .
