Psalidothrips daguilari sp.n.

( Figs 8 , 48 )

Female aptera. Body brown, head paler than pronotum, abdominal segment IX and tube lighter than rest of abdomen; legs mainly yellow; antennae brownish yellow, but segment II shaded with brown. Head without sculpture; genae not clearly constricted behind eyes; ocelli absent, compound eyes with 2 large and 1 small facets; postocular setae long and bluntly pointed, longer than half the distance between their bases; postocellar setae minute; maxillary stylets about two-thirds of head width apart ( Fig. 8 ), retracted half way to postocular setae (displaced in most specimens). Antennal segments III–IV each with 2 slender sense cones, III–VII each with pedicel; VIII weakly narrowed at base; segment III longer than IV, VIII longer than VII. Pronotum without sculpture; setae aa, ml, epim and pa well-developed, am as long as median discal setae. Mesonotum and metanotum without sculpture. Mesopresternum absent, mesoeusternal anterior margin weakly eroded. Fore tarsal tooth absent. Pelta eroded, posterior margin weakly separated from tergite II, campaniform sensilla present or absent; tergites II–VII each with one pair of minute straight wing-retaining setae; median setae minute on II–VII but long on VIII; tergite IX setae S1 shorter than tube ( Fig. 48 ), anal setae as long as tube.

Measurements (holotype female in microns). Body length 1770. Head, length 143; basal width 168; postocular setae 76, distance between their bases 120; postocellar setae 6, distance between their bases 41. Pronotum, length 130; median width 250; major setae am 12, aa 40, ml 68, epim 68, pa 75. Mesonotum posteromarginal setae 23. Metanotum median setae 25. Tergite IV median marginal setae 102; tergite VIII median setae 85, tergite IX setae S1 97, S2 93. Tube length 117; anal setae 113. Antennal segments III–VIII length 47, 40, 43, 43, 32, 37.

Male aptera. Similar to female but colour lighter; fore tarsal tooth present; sternite VIII pore plate transverse, wide and reaching lateral margins of sternite.

Measurements (in microns). Body length 1550. Head, length 133; width 135; postocular setae 60, postocellar setae 8. Pronotum, length 120; median width 220; major setae am 15, aa 40, ml 62, epim 65, pa 65. Tergite VIII median setae 65, tergite IX setae S1 70, S2 62. Tube length 100; anal setae 105. Antennal segments III–VIII length 44, 38, 40, 38, 30, 36.

Specimens studied. Holotype female aptera. Queensland, Brisbane Forest Park, Centre Rd. , from litter, 5.x.2008 ( DJT 731 ), in ANIC.

Paratypes: 1 female, 1 male, same locality as holotype; Queensland, Mt. Coot-tha , 3 males from dry sclerophyll litter, 12.vii.2008.

Non-paratypes: Queensland, Brisbane Forest Park, Boombana, 1 male from wet sclerophyll litter, 2.viii.2008; Carnarvon Station , 1 female in pitfall trap, 15.x.2014 .

Comments. The body structure and sclerites of this species are similar to postlei and greensladeae , and these three differ in the character states given in the key. The pore plate of the male extends across the full width of sternite VIII. The male from Boombana differs in having the pore plate interrupted medially, and also in lacking a fore tarsal tooth.
