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 : 19-21

Anaphothrips augustae sp. n.

( Figs 24–28 )

Female macroptera. Body, legs and antennal segments I–III yellow, IV weakly shaded at apex, V yellow in basal half, VI–IX light brown; wings pale; tergite IX setae light brown. Head wider than long, with closely spaced sculpture lines behind eyes ( Fig. 24 ); eyes with 6 pigmented facets; ocellar setae III outside ocellar triangle. Antennae 9-segmented; III–IV with sensorium forked, II without microtrichia; VI not pedicellate, suture between VI–VII oblique ( Fig. 26 ). Pronotum with closely spaced, faint, transverse lines of sculpture; discal setae small. Metascutal sculpture transverse on anterior half, irregularly reticulate medially ( Fig. 27 ); median setae fine and well back from anterior margin; MCS absent. Prosternal ferna almost complete medially. Fore wing first vein with about 9 setae basally, 2 setae medially and 2 setae near apex; second vein with 12–15 setae; clavus with 5–6 veinal setae. Abdominal tergites II–VII with no sculpture medially, lateral to setae S2 with about 10 closely spaced lines bearing microtrichia similar to some Scirtothrips species ( Fig. 25 ); VIII with long regular marginal comb. Sternite VII median setae close to posterior margin.

Measurements (holotype, in microns). Body length 1280. Head, length 70; width across eyes 135. Pronotum, length 85; maximum width 160. Fore wing, length 700; median width 65; first vein longest seta in basal row 15. Tergite IV S1 setae 12. Tergite IX, MD setae 10; PM S1 setae 70. Tergite X PM S1 setae 55. Antennal segments III–IX, 45, 30, 32, 32, 10, 8, 10.

Male macroptera. Similar to female; tergite IX with all setae slender; sternite III with pair of circular pore plates at anterolateral angles ( Fig. 28 ).

Larvae. White with tergites IX–X deeply shaded. Most dorsal setae finely acute; tergite IX with 2 pairs of stout capitate setae, X with one pair.

Specimens examined. Holotype female macroptera, South Australia, 35km southwest of Port Augusta, from Myoporum leaves ( Myoporaceae ), 30.xii.1997 (LAM 3378).

Paratypes: 18 females 5 males taken with holotype.

Non-paratypic specimens: Queensland, Dalby 55km west, 2 females from Myoporum leaves, 28.iii.1998 .

Comments. The pair of small circular pore plates anterolaterally on the third sternite of males is a character state not known in any other species. The tergal sculpture with rows of small microtrichia in both sexes is similar to that of some Scirtothrips species. Females are similar to those of A. barrowi and A. barringtoni , but in these the microtrichia are less well developed. In A. cobari the microtrichia are effectively absent, and the male differs in having a median, weakly transverse, pore plate on the third sternite.
