Mound, Laurence A. & Masumoto, Masami, 2009, Australian Thripinae of the Anaphothrips genus-group (Thysanoptera), with three new genera and thirty-three new species, Zootaxa 2042 (1), pp. 1-76 : 66-69

Ozanaphothrips perotis sp. n.

( Figs 198 –204)

Female macroptera. Body and legs light brown, except apices of tibiae and all tarsi yellow; antennal segment I as brown as head, II dark brown, III–V yellow, VI–VIII very light brown ( Fig. 198 ); fore wing weakly shaded particularly on posterior half. Head projecting in front of eyes, with two swellings over base of antennal segment I, fore ocellus reduced ( Fig. 199 ); ocellar setae pair I placed far forward of pair II, sometimes absent, pair III between posterior ocelli; eyes large, cheeks straight. Antennal segment IV with sensorium forked, IV–V with very few microtrichia. Pronotum trapezoidal, weakly sculptured, setae all small. Mesonotum reticulate, median pair of setae not close to posterior margin. Metascutum reticulate, median setae arise medially, no MCS. Mesothoracic sternopleural sutures incomplete at anterior margin; furca with weak spinula. Fore wing first vein with 5 basal and 2 distal setae, second vein with 5 setae; clavus with 3 veinal setae. Abdominal tergite I reticulate, with no craspedum; tergites II–VIII very weakly reticulate medially with broad posteromarginal craspedum bearing many small lobes ( Figs 200 , 201); campaniform sensilla close to posterior margin; tergite IX MD setae slender but arising medially; tergites IX–X dorsal setae stout and weakly capitate ( Fig. 200 ). Sternites without craspeda, marginal setae arise submarginally, 4 to 10 discal setae in irregular transverse row medially (Fig. 202).

Measurements (holotype, in microns). Body length 1400. Head, length 110; width across eyes 125. Pronotum, length 140; maximum width 185. Fore wing, length 700; first vein longest seta in basal row 10. Tergite IV S1 setae 20. Tergite IX, MD setae 20; PM S1 setae 55. Tergite X PM S1 setae 50. Antennal segments III–VIII, 35, 30, 30, 45, 10, 15.

Female microptera. Similar to macroptera, ocelli present, wing lobe shorter than median length of mesonotum; mesonotum and metascutum transverse.

Male microptera. Sharply bicoloured; mainly yellow, abdominal segments II–III dark brown, IV lighter brown around anterior and lateral margins; head shaded with brown laterally and at anterior margin; antennal segment I brown, II dark brown, III–V yellow, VI–VIII light brown. Head and pronotum similar to female; abdominal tergites II–VIII with craspeda deeply lobed (Fig. 203); tergite IX median setae small and far apart, two pairs of stout posterolateral setae; sternites III–VIII with increasingly smaller transversely oval pore plates close to antecostal ridge, lateral discal areas of sternites with many stout microtrichia (Fig. 204).

Specimens examined. Holotype female macroptera. Western Australia, 20km east of Broome, from Perotis rara ( Poaceae ), 1.iii.2005 (LAM 4650).

Paratypes: 2 female macropterae, 5 female 2 male apterae taken with holotype; Western Australia, Broome, 1 female macroptera, lawn grass, 28.ii.2005; Kununurra, 1 female aptera, Echinochloa (Poaceae) , 22.ii.2005, 1 female macroptera, from grass, 24.ii.2005, 1 female without data, i.1991. Northern Territory, Darwin, Holmes Jungle, 1 female 1 male apterae, grasses, 2.i.1996.

Comments. The head, pronotum and fore wings are similar to those of O. fenarius , but the sternites lack craspeda and the metascutum lacks campaniform sensilla.
