Mesandrothrips lamingtoni sp.n.

( Figs 14 , 22)

Male microptera. Body and femora light brown, with head and tube darkest; antennal segments IV–VIII dark brown, III yellow in basal third and light brown distally, I and II slightly paler than head; tarsi, tibiae and apices of femora yellow; major setae pale. Antennal segment III slender in basal third ( Fig. 14 ), apex angular, with slender sense cones; IV–VII each with distinct pedicel. Head scarcely longer than wide ( Fig. 22 ), vertex with no sculpture; posterior ocelli faintly indicated; postocular setae weakly capitate, longer than dorsal eye length; maxillary stylets wide apart, V-shaped, retracted almost to postocular setae. Pronotum without sculpture lines, anteromarginal setae minute; four pairs of long, weakly capitate major setae. Mesonotum weakly sculptured, lateral setae softly pointed; metanotum without sculpture lines, median setae small and acute. Fore tarsal tooth pointed, longer than half tarsal width ( Fig. 22 ). Fore wing lobe small, with two long setae at apex. Mesopresternum reduced to two small triangles. Pelta small and triangular; tergites II–VII each with 2 pairs of minute wingretaining setae, marginal setae S1 weakly capitate and longer than each of their tergites, setae S2 on VII long and finely acute; tergite IX setae S1 bluntly pointed, S2 shorter and stouter. Sternite VIII without a pore plate.

Measurements (holotype male in microns) Body length 1630. Head, length 150; width 140; postocular setae 65. Pronotum, length 125; with 200; major setae, aa 50, ml 60, epim 65, pa 75. Fore wing lobe 60. Tergite IV posteromarginal setae S1 85, S2 50. Tergite IX setae, S1 80; S2 35. Tube, length 100; basal width 55. Antennal segments III–VIII length 50, 50, 45, 40, 35, 30.

Female microptera. Larger than male but similar in colour and structure; head with a few sculpture lines laterally, pronotum with weak median longitudinal thickening, but metanotum with no sculpture; mesopresternum continuous but slender medially.

Measurements (paratype female in microns) Body length 2450. Head, length 190; width 170; postocular setae 80. Pronotum, length 175; width 280; major setae, aa 50, ml 80; epim 80, pa 90. Fore wing lobe 75. Tergite IX setae, S1 105, S2 110. Tube, length 135; basal width 70. Antennal segments III–VIII length 70, 70, 60, 60, 50, 35.

Material studied. Holotype male, Australia, Queensland, Lamington, O’Reilly’s , in yellow pan trap, vii.2007 (Desley Tree), in ANIC.

Paratypes: 1 female in leaf-litter at same locality as holotype; Queensland, Brisbane Forest Park, Mt Glorious , 2 females in Macrozamia leaf-litter, 13.ix.2009 (inANIC)

Comments. All four of the available specimens are remarkable for the lack of sculpture on the head, pronotum and metanotum. Each of the three female specimens has the maxillary stylets dissociated.
