Dendrothrips julatteni sp.n.

Female macroptera: Head, body and legs mainly light brown, pterothorax darkest, abdominal tergites pale medially, tarsi yellow; antennal segment I light brown, II–III dark brown, IV–V yellow, VI–IX light brown with VI paler at base; fore wing weakly shaded with 3 pale areas, sub-basally, medially and sub-apically, clavus uniformly dark.

Head with ocellar triangle finely tuberculate ( Fig. 5 ), with a few reticulate lines at posterior margin, ocellar setae III just outside ocellar triangle. Antennae 9-segmented ( Fig. 7 ); sense cone on VI arising near base of segment but extending beyond apex of IX; sense cones on III and IV stoutly U-shaped. Pronotum with complex irregular sculpture and markings within the reticles ( Fig. 5 ). Metanotum longitudinally reticulate with internal markings ( Fig. 8 ). Fore wing typical of genus, major setae scarcely longer than microtrichia, anteromarginal cilia arising ventrally well behind margin. Tergites II–VII strongly reticulate with complex short longitudinal sculpture lines on posterolateral areas ( Fig. 6 ), VIII with long marginal comb, IX with many discal microtrichia.

Measurements (holotype female in microns). Body length 1050. Head, length 50; width across eyes 160. Pronotum, length 80; width 175. Fore wing length 750. Antennal segments III–IX length 27, 30, 25, 20, 7, 12, 12.

Material studied. Holotype female, Australia, Queensland, Julatten, from Arthropteris tenella [Filicopsida], 6.viii.2004 (LAM4446), in ANIC.

Comments. This species is unique within the genus in having antennal segment III as dark brown as segment II. It is also readily distinguished by the sculpture of the pronotum and metanotum.
