Ozanaphothrips kununurrai sp. n.

( Figs 193–197 )

Female macroptera. Body and legs brown, but tarsi and apices of tibiae and femora yellow; antennal segments brown ( Fig. 194 ), II dark brown; fore wings pale. Head projecting in front of eyes ( Fig. 193 ), vertex swollen over base of antennal segment I, fore ocellus reduced; ocellar setae pair I situated far forward of pair II, sometimes absent, pair III between posterior ocelli; eyes large, cheeks straight. Antennal segment IV with simple sensorium, IV–V with microtrichia on transverse ridges; pedicel of III slightly swollen. Pronotum transverse ( Fig. 193 ), with sculptured lines, no discal setae; 4–6 posteromarginal setae, of which pair S6 (?8) almost three times as long as minor setae. Mesonotum reticulate, median pair of setae distant from posterior margin; without campaniform sensilla anteromedially. Metascutum weakly reticulate medially ( Fig. 197 ), median setae arise close to anterior margin, no MCS. Mesothoracic furca without spinula. Fore wing first vein with 4 basal and 2 distal setae, second vein with 2 setae; clavus with 4 veinal setae. Abdominal tergite I with weak sculpture at anterior, no craspedum medially ( Fig. 196 ); tergites II–VIII without sculpture medially, with narrow posteromarginal craspedum; campaniform sensilla not close to posterior margin; tergite IX MD setae long. Sternites without craspeda, marginal setae arise at margin ( Fig. 195 ), including S1 on VII; 0 to 6 discal setae in irregular transverse row medially on IV–VII.

Measurements (holotype, in microns). Body length 1300. Head, length 130; width across eyes 145. Pronotum, length 100; maximum width 185. Fore wing, length 680; first vein longest seta in basal row 20. Tergite IV S1 setae 5. Tergite IX, MD setae 30; PM S1 setae 85. Tergite X PM S1 setae 60. Antennal segments III–VIII, 35, 35, 35, 50, 10, 12.

Male macroptera. Colour and structure similar to female, but abdomen slender; tergite IX posterior margin with pair of short, dark-tipped, upwardly curved, drepanae; sternite III with transverse pore plate close to antecostal ridge.

Comments. The number of sternal discal setae varies amongst the paratypes. One female has two such setae on sternite III, although this sternite has no discal setae on any of the other specimens. Most females have about four discal setae on sternites IV and V, and about six on VII, however, one female has no discal setae on II – VI and just one on VII placed laterally. The only available male has the abdomen mounted laterally, and is thus difficult to study .

Specimens examined. Holotype female macroptera. Western Australia, Kununurra, from Fimbristylis (Cyperaceae) , 22.ii.2005 (LAM 4553).

Paratypes: 2 females taken with holotype; Kununurra, Ivanhoe, 6 female 1 male from grasses, 24.ii.2005; Kununurra, 1 female from Sesbania , 22.ii.2005.

Comments. The head is similar to that of O. fenarius , but the pronotum is transverse, unlike the trapezoidal condition found in the other species in this genus.
