Dendrothrips stannardi (Ananthakrishnan)

( Figs 11 , 14, 16 , 35 , 49 , 67–68 )

Dendrothripiella stannardi Ananthakrishnan, 1958: 216 .

Described from southern India, reputedly from Cinchona [ Rubiaceae ], this species is quite common in southwest China, and is generally associated with Buddleja [ Scrophulariaceae ] ( Han 1997 and this study). It is unique among species of Dendrothrips from China in having 7-segmented antennae, with antennal segments VI and VII fused together, leaving VIII as the visible seventh segment ( Fig. 49 ), and it is also easily recognized by the rather regular polygonal tergal reticulations ( Fig. 35 ).

Female: Body mainly brown, pronotum and lateral areas of abdomen paler ( Fig 67 ); antennae brown but segments III–IV pale; fore wing pale at base, subbase brown, apical half pale brown to pale. Antennae 7-segmented, III–IV with forked sense cones. Head reticulate posteriorly, pronotum with transverse and irregular striae bearing microflanges, without internal markings ( Fig. 11 ). Mesonotum with transverse reticles; metanotum with longitudinal reticles bearing inner markings. Fore wing surface with wrinkles and larger microtrichia on veins ( Fig. 14 ), first vein with 13 setae and second vein with 3 setae. Abdominal tergites laterally with polygonal reticulations ( Fig. 35 ), posterior margin with short microtrichia.

Male: similar to female, but abdomen slender and paler ( Fig. 68 ).
