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 : 47-49

Anaphothrips orchis sp. n.

( Figs 125–127 )

Female macroptera. Body, antennae and legs brown, tarsi slightly paler; fore wings shaded but paler near base. Head wider than long, sculptured behind eyes but not near ocelli; eyes with 6 pigmented facets; ocellar setae III on anterior margins of triangle ( Fig. 126 ). Antennae 9-segmented; III–IV with forked sensorium; III unusually short, VII–IX elongate; II–V with few or with no microtrichia; VI narrowed to base but not pedicellate; IX longer than VIII ( Fig. 125 ). Pronotum weakly sculptured, with few discal setae. Metascutum reticulate; median setae small, on anterior third of sclerite; MCS present. Fore wing setae well developed, first vein with 8–9 basally, 3 medially and 2 distally; second vein with 11 setae including one seta basal to vein fork; clavus with 6 veinal setae and one basal seta. Abdominal tergites IV–VII with no sculpture medially, lines scarcely extend mesad of setae S2; VIII with posteromarginal comb of slender but rather widely spaced microtrichia ( Fig. 127 ); setae on IX–X long.

Measurements (holotype, in microns). Body length 1450. Head, length 110; width across eyes 150. Pronotum, length 115; maximum width 190. Fore wing, length 700; median width 50; first vein longest seta in basal row 20. Tergite IV S1 setae 7. Tergite IX, MD setae 10; PM S1 setae 105. Tergite X PM S1 setae 115. Antennal segments III–IX, 37, 35, 30, 32, 15, 12, 23.

Male unknown.

Specimens examined. Holotype female macroptera, New South Wales, Kinghorn Point, from Prasophyllum affine (Orchidaceae) , ix.2001 (D.L.Jones).

Paratypes: 4 females taken with holotype; South Australia, Adelaide Hills , 5 females from orchids, 1998; Adelaide Hills, Scott Creek , 1 female from native grasses, 16.x.2004.

Comments. The uniformly brown colour of the body of this orchid-living species, also the short brown third antennal segment, is distinctive within the genus Anaphothrips . The inner lobe of the forked sensorium on the third antennal segment is not always fully developed, and the ninth segment is unusually long.
