description: Adrothrips latrarei sp.n.
(Figs 5, 16, 24, 29)
Female microptera. Body uniformly light brown, antennal segments III–VI variably yellowish near base; legs brown with apex of fore tibiae and all tarsi yellow; major setae all pale. Head longer than wide, eyes larger dorsally than ventrally, ocelli reduced; postocular setae small and acute or weakly capitate; vertex with weak transverse narrow reticulation. Maxillary stylets retracted almost to eyes, close together medially, each with three coils posterolaterally before entering the mouth cone (Fig. 16). Antennae robust, segment III with one sense cone about half as long as apical width of segment, basal pedicel produced into strong ring (Fig. 5); segments IV and V each with 2 sense cones; apex of V almost symmetrical, of VI broad; VIII small and closely joined to VII. Pronotum with weak, transverse sculpture only near posterior margin, anteromarginal setae minute, midlaterals small but capitate. Metanotum irregularly reticulate, without internal markings, bearing up to 16 small setae (Fig. 24). Mesopresternum fully transverse, projecting forwards medially (Fig. 29); ferna almost meeting medially. Fore tarsal tooth small, fore tibiae simple. Fore wing lobe usually shorter than thorax width but sometimes slightly longer. Pelta D-shaped to triangular, weakly reticulate (Fig. 24); tergites with transverse row of fine setae medially, anterior pair of wingretaining setae reduced on each tergite, both pairs reduced or absent on VII; tergite IX setae capitate and shorter than basal width of tube; tube rather slender, twice as long as basal width.
Measurements (holotype female in microns). Body length 2500. Head, length 260; width medially 230; po setae 25. Pronotum, length 175; width 275; major setae – am 12, aa 35, ml 25, epim 40, pa 30. Fore wing length 230; sub-basal setae 25. Tergite IX setae S1 60, S2 85. Tube, basal width 85, length 185. Antennal segments III–VIII length 70, 65, 65, 70, 25, 25.
Male microptera. Slightly smaller, but very similar in colour and structure to female; tergite IX setae S2 slightly longer than setae S1.
Specimens studied. Holotype female microptera, Queensland, Brisbane, Mt Glorious, Dundas Road, from barkspray on Eucalyptus trunk, 29.x.2008 (DJ Tree 756), in ANIC.
Paratypes 2 females, 3 males collected with holotype; Queensland, Carnarvon N.P., Mt Moffat Consuelo Tableland, 2 females from barkspray on Eucalyptus, 17.i.2013; in ANIC and QDPC.
Comments. Among members of this genus this species shares only with lihongae sp.n. the presence of a sense cone on antennal segment III. In contrast to that species the maxillary stylets are very long and arranged into three coils posterolaterally (Fig. 16), the pedicel of antennal segment III has a strong sub-basal ring, the surfaces of the head and thorax are not reticulate, and the body is uniformly brown. The only available specimens were taken by insecticide fogging on the trunk of Eucalyptus trees, and the specific epithet refers to this finding place.
