Poliaspis araucariae Hardy & Henderson sp. n. Fig. 2
Material examined.
Holotype: female: Australia, QLD, Taromeo [-26.83, 152.12], Araucaria bidwillii, 1.9.1937, A Brimblecombe, 165; 1185/10387 (ANIC).
Paratypes: QLD: 10 adult females: Gallangowan [-27.93, 151.67], ex Araucaria cunninghamii, 15.2.1944, Se/1945 (QDPI); 8 adult females: same data as holotype (QDPI).
Description, n=7.
Slide-mounted adult female 724-1658 μm long (holotype 1016 μm long), body outline fusiform-pyriform, thoracic and abdominal lobes produced. Pygidium with 2 pairs of lobes; median lobes divergent, connected medially by narrow sclerotic strap, lobes with rounded apex; margin between lobes weakly incised; second lobe bi-lobed, each lobule with basal sclerosis, more strongly developed on medial lobule. Gland spines 12-27 μm long, 2-3 × length of median lobes, 1 gland spine on margin of each pygidial segment; pair of minute setae absent between median lobes. Dorsal ducts similar in size to marginal ducts; present in rows; 1-2 submedial ducts present on segment 6; ca. 6 submarginal and ca. 5 submedial ducts on segment 5. Perivulvar pores: 5-14 posteromedial, 9-20 posterolateral, 23-27 posterior, 1-8 anteromedial, and 7-12 anterolateral. Trilocular pores in cluster of 2-4 near anterior spiracle; absent from posterior spiracle. Microducts scattered on head dorsum, anterior to anterior spiracles and mesad of gland tubercles on thorax and abdomen. Antenna with 2 fleshy setae.
Comments.
The one or two submedial ducts on abdominal segment 6, in addition to the absence of setae between the median lobes (also absent in Poliaspis callitris, and Poliaspis nitens) can be used to distinguish Poliaspis araucariae from other species of Poliaspis .
Etymology.
The species name refers to the host species: Araucaria cunninghamii and Araucaria bidwillii .
