Mound, Laurence A. & Tree, Desley J., 2016, Genera of the leaf-feeding Dendrothripinae of the world (Thysanoptera, Thripidae), with new species from Australia and Sulawesi, Indonesia, Zootaxa 4109 (5), pp. 569-582 : 575-576

Dendrothrips notelaea sp. n.

Female macroptera: Head, body and legs mainly pale; pronotum, also tergites III–VII, with 2 pairs of brown spots on lateral thirds; tarsi and hind tibiae yellow; antennal segment I white, II dark brown, III–IV yellow, V yellow at base but distal segments brown; fore wing pale with two weakly shaded areas medially and sub-apically that do not form transverse bands, also a dark spot on posterior margin close to dark apex of clavus.

Head sculpture finely tuberculate ( Fig. 9 ), with a few reticulate lines at posterior margin, ocellar setae III just outside ocellar triangle. Antennae 7-segmented ( Fig. 11 ); sense cone on VI arising near apex of segment; sense cones on III and IV stoutly V-shaped. Pronotum with irregular transverse reticles of which the marginal ridges are flattened ( Fig. 9 ), with no (or weak) markings within the reticles. Metanotal sculpture irregularly tuberculate/ reticulate ( Fig. 10 ). Fore wing typical of genus, major setae scarcely longer than microtrichia, anteromarginal cilia arising ventrally well behind margin. Tergites III–VII posterolaterally with short longitudinal sculpture lines ( Fig. 12 ), VIII with short marginal comb, IX with many discal microtrichia on posterior third.

Measurements (holotype female in microns). Body length 950. Head, length 55; width across eyes 135. Pronotum, length 80; width 150. Fore wing length 650. Antennal segments III–VII length 30, 33, 25, 33, 10.

Material studied. Holotype female, Australia, New South Wales, 50km north of Narrabri, from Notelaea microcarpa, 15.vii.1968 (LAM 722), in ANIC.

Paratypes, 4 females taken with holotype; Queensland, Carnarvon Station, 3 females from leaf litter and tree bark spray, 14.x.2014, same locality, 1 female from Melaleuca leaves, 16.x.2014; Stanthorpe, 1 female from Olea europaea , 9.xi.2001; Brisbane, Moggill, 1 female in nursery, 8.xii.1997; Brisbane, Mt. Glorious, 1 female from Cyathea , 6.ix.2009.

Comments. This species shares a similar pronotal sculpture with diaspora and victoriae , as mentioned below under the latter species. The distal antennal segments are more foreshortened than in any other species of this genus from Australia, particularly in contrast to the condition found in julatteni and victoriae .
