Diagnosis . Apterous or macropterous; antennae 8-segmented ( Figs 183, 187 ), sensorium on segment III simple, antennal microtrichia weak, absent on segment III; segment I without dorso-apical setae. Head projecting in front of eyes, vertex often swollen over bases of antennal segment I ( Figs 188 , 199 ); 3 pairs of ocellar setae but pairs I and II sometimes absent; no more than 3 pairs of postocular setae; eyes large, with 6 pigmented facets; maxillary palps 2-segmented, mouth cone robust and projecting ventrally. Pronotum with no long setae, or with one lateral pair (S8?) prominent; ferna usually entire; basantra without setae. Metapreepisternum transverse. Tarsi 2-segmented. Mesothoracic furca usually with spinula, metathoracic furca without spinula. Mesonotum with paired campaniform sensilla anteromedially. Mesothoracic sternopleural sutures usually complete. Fore wing with reduced chaetotaxy, first vein with 2 setae on distal half, second vein with no more than 6 setae; clavus with neither discal seta nor basal seta; marginal cilia wavy. Abdominal tergites II–VIII with distinct craspedum; median setae on tergites not close together, campaniform sensilla usually close to posterior margin; IV–VI with lateral marginal setae no longer than S1 and S2; tergite IX with 2 pairs of campaniform sensilla, MD setae often long and situated medially; tergite X dorsal split and major setae usually short. Sternites III–VII with 3 pairs of marginal setae, sometimes arising sub-marginally, rarely without several discal setae. Males (where known) with a pore plate close behind antecostal ridge on sternite III or III–VII ( Fig. 192 ); tergite IX without dorsal paired thorn-like setae. Type species Ozanaphothrips fenarius sp. n. Comments. This genus shares many character states with Bregmatothrips Hood , but these similarities are possibly due to convergence given that all of the species in both of these genera live on Poaceae (possibly also Cyperaceae ). In Bregmatothrips species the first antennal segment bears a pair of dorso-apical setae, there are two pairs of long pronotal posteroangular setae, and the males lack sternal pore plates. In general appearance, species of Anaphothrips are particularly similar, but these lack sternal discal setae, and in males the sternal pore plates are usually on the discal area and only rarely closely parallel to the antecostal ridge. In some species of this new genus the chaetotaxy is not stable, including the number and position of ocellar setae, the number of pronotal posteromarginal setae, and the number and disposition of sternal discal setae. The genus also shares many character states with Monothrips flavus Moulton , a species described from New Guinea , but of which several specimens have been seen from northern and northwestern Australia . Currently Monothrips is distinguished because of the presence of two pairs of long pronotal posteroangular setae, but the new species described below, O. torridus , is particularly similar to M. flavus .
