Ozanaphothrips fenarius sp. n.

( Figs 185–192 )

Female macroptera. Body, legs and antennae dark brown, antennal segment II darkest; major setae on abdominal apex dark. Fore wing uniformly brown. Head reticulate on posterior third, projecting slightly in front of eyes, cheeks straight; eyes large. Antennal segment IV with forked sensorium, II–V annulate, IV–VI with few microtrichial rows dorsally and ventrally ( Fig. 187 ). Pronotum trapezoidal ( Fig. 188 ), reticulate, setae small, posteromarginal seta pair S8 slightly more prominent. Mesonotum reticulate, median pair of setae not close to posterior margin. Metascutum reticulate, median setae arise medially, MCS near posterior ( Fig. 185 ). Mesothoracic sternopleural sutures incomplete at anterior margin; furca with prominent spinula. Fore wing first vein with 5–6 basal and 1–2 distal setae, second vein with 2 setae; clavus with veinal setae varying 3–6. Abdominal tergites I–VIII reticulate, with broad unlobed but slightly dentate posteromarginal craspedum, paired campaniform sensilla close to posterior margin; posteromarginal setae arise slightly in front of margin; tergite IX MD setae long and wide apart, major setae short. Sternites II–VII reticulate, with broad unlobed posteromarginal craspedum, on VII not developed mesad of setae S2; sternites II–VII posteromarginal setae arise in front of margin, III–VII with discal setae indistinguishable from marginals ( Fig. 191 ).

Measurements (holotype, in microns). Body length 1550. Head, length 130; width across eyes 125. Pronotum, length 160; width 180. Fore wing, length 850; first vein longest seta in basal row 20. Tergite IV S1 setae 15. Tergite IX, MD setae 40; PM S1 setae 90. Tergite X PM S1 setae 65. Antennal segments III–VIII, 45, 40, 37, 45, 10, 10.

Female aptera. Colour and structure similar to macroptera. Mesonotum reticulate, with 2 pairs of campaniform sensilla anteromedially, 2 pairs of setae near posterior margin. Metascutum reticulate, transverse with 2 pairs of setae medially; MCS near posterior ( Fig. 186 ). Mesothoracic sternopleural suture weak or absent; furca with small spinula. Tergite IX MD setae shorter than in macropterae.

Male aptera. Colour and structure similar to female. Abdominal tergite IX with all setae small; sternites III–VII each with transverse pore plate close to antecostal ridge ( Fig. 192 ).

Second instar larva with red internal pigment; head thickened and dark on dorsal surface except Y-shaped pale membranous area; antennal segment I dark with outer side of distal half pale, segment II dark with distal half pale, segment III dark with base and apex pale, segments IV to VII dark; pronotum thickened and dark at each side; each notum of thorax with a pair of small thickened dark spots; all femora dark with distal half pale, all tibiae dark on outer margin and basal half of inner margin; abdominal segment IX dark distal two-thirds, segment X dark. Antennal segments annulated and without microtrichia; body surface granulated, with setae short and stout but not expanded at apex.

Specimens examined. Holotype female macroptera, Western Australia, Geraldton , from Phalaris paradoxa , 23.x.1994 (Steiner & Goodwin).

Paratypes: 29 female macroptera taken with holotype; Western Australia, Meekathera, 2 female aptera, from grasses, 20.iv.200; Perth, from grasses, 2 female 2 male apterae with larvae, 28.ix.1995, 8 female apterae, 29.ix.1995; Meckering, 14 female apterae, from Pinus pinaster , 4.xi.1998; Regan Ford, 2 female macropterae, from Triticum , 19.x.1994; Narrogin, 3 female apterae, 2 female macropterae, fogging Eucalyptus , x.2006; Mt Barker, 1 female macroptera, from Conostylus, 3.x.1995; intercepted from Australia at Narita Airport, Japan, 1 female macroptera from Asparagus officinalis [ Liliaceae ], 22.xi.2001 (N. Matsumoto, plant quarantine, Japan).

Non-paratypic specimens: Western Australia, Rawlinna , 30 female apterae, 9.viii.1968 . South Australia, Cox Scrub near Adelaide , 1 female aptera, 14.i.2002 . ACT, Canberra, Mulligans Flat , 1 female aptera, 6.xii.2003 .

Comments. This species is widespread in Western Australia, from Geraldton and Meekathera south to Mt Barker. The specimens listed from Rawlinna on the Nullarbor Plain are undoubtedly the same species, but are all severely crushed. The other two non-paratypic specimens appear to be the same species. However, they both come from areas that have been collected at frequently without further specimens being found, therefore these distribution records should be treated with caution. Many of the larvae from grasses at Perth were full of the black spores of Neozygites (Entomophthorales) (identified courtesy of Roger Shivas, QDPI).
