Psalidothrips postlei View in CoL sp.n.

( Figs 11 View FIGURES 10–18 , 28 View FIGURES 19–37 , 46 View FIGURES 38–49 )

Female aptera. Head, prothorax and abdomen segments II–VIII light brown, posterior part of metathorax and abdominal segment I paler, segment IX and tube yellowish; tibiae and tarsi mainly yellow but femora darker; antennae brownish yellow. Head without sculpture medially but with weak transverse lines laterally; genae not clearly constricted behind eyes; ocelli absent, compound eyes with three facets; postocular setae bluntly pointed, longer than half the distance between their bases, postocellar setae minute; maxillary stylets retracted almost to postocular setae, about one-third of head width apart ( Fig. 11 View FIGURES 10–18 ). Antennal segments III and IV each with 2 slender sense cones, III–VII each with pedicel; VIII broadly joined to VII with suture sometimes weakly developed; segment III longer than IV, VIII as long as VII. Pronotum without sculpture; setae ml, epim and pa well-developed, aa much longer than median setae, am minute; mesonotum and metanotum without sculpture. Mesopresternum absent, mesoeusternal anterior margin eroded. Fore tarsal tooth absent. Pelta strongly eroded, even absent ( Fig. 46 View FIGURES 38–49 ); 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, anal setae shorter than tube. Sternites with one pair of minute discal setae.

Measurements (holotype female in microns). Body length 2088. Head, length 148; width 156; postocular setae 68, distance between their bases 119; postocellar setae 10, distance between their bases 27. Pronotum, length 144; median width 246; major setae am 7, aa 44, ml 68, epim 80, pa 79. Mesonotum posteromarginal setae 9. Metanotum median setae 27. Tergite IV median marginal setae 102; tergite VIII median setae 94, tergite IX setae S1 122, S2 122. Tube length 131; anal setae 116. Antennal segments III–VIII length 51, 42, 42, 42, 34, 33.

Male aptera. Similar to female but antennal segments III–VIII brown, tergite IX yellow; fore tarsal tooth absent; sternite VIII pore plate transverse but very slender and not reaching lateral margins of sternite ( Fig. 28 View FIGURES 19–37 ).

Measurements (in microns). Body length 1435.Head, length 143; width 122; postocular setae 60, postocellar setae 6. Pronotum, length 111; median width 187; major setae am 5, aa 41, ml 60, epim 69, pa 65. Tergite VIII median setae 66. Tergite IX setae S1 75, S2 68. Tube length 114; anal setae 94. Antennal segments III–VIII length 37, 29, 32, 32, 30, 25.

Specimens studied. Holotype female aptera. Western Australia, Dwellingup , from litter, 24.x.1980 (A. Postle), in ANIC.

Paratypes: 1 female and 1 male, same locality as holotype, 24.ii.1981 and 20.vii.1981 .

Comments. The body structure and sclerites of this species are similarly pale and eroded to greensladeae , and these two differ in the character states given in the key. The pore plate on sternite VIII of the male is unusually slender.
