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 : 576

Dendrothrips victoriae sp.n.

Female macroptera: Head, body and legs largely brown, but pronotum and mesonotum sharply pale, also tarsi and posterolateral areas of tergites II–VII; antennal segment II dark brown, segments I and III–IX uniformly light brown; fore wing uniformly lightly shaded except for anterior two-thirds at base, clavus pale with apex brown.

Head with irregular sculpture lines ( Fig. 18 ), ocellar setae III minute on anterolateral margins of triangle. Antennae 9-segmented ( Fig. 16 ); suture on VI not fully complete, sense cone arising on basal third of segment; sense cones on III and IV unusually small and slender. Pronotum with irregular transverse reticles of which the marginal ridges are flattened ( Fig. 18 ), with no markings within the reticles. Metanotal reticulation longitudinal, median setae minute ( Fig. 19 ). Fore wing typical of genus, major setae no longer than microtrichia, anteromarginal cilia arising ventrally well behind margin. Tergites III–VII posterolaterally with short longitudinal sculpture lines ( Fig. 17 ), VIII with short marginal comb, IX with many discal microtrichia on posterior third.

Measurements (holotype female in microns). Body length 1250. Head, length 85; width across eyes 160. Pronotum, length 95; width 200. Fore wing length 850. Antennal segments III–IX length 33, 30, 30, 30, 7, 7, 12.

Material studied. Holotype female, Australia, Victoria, near Bendigo, from Daviesia sp. [ Fabaceae ], i.2014 (Renae Forbes), in ANIC.

Comments. The sculpture of the pronotum is similar to that of notelaea and diaspora, suggesting that these represent an Australian radiation within this genus, which is possibly in association with species of Oleaceae . This species is distinctive for the weak sculpture on the head and the almost uniformly light brown antennae and fore wing.
