This species seems to be particularly unusual within Dendrothrips in having ocellar setae pair III within the ocellar triangle, a condition shared only with guttatus . The pronotal sculpture is remarkably sexually dimorphic, and demonstrates an interesting correlation between the presence of pronotal transverse striae and longer posteroangular setae (in males), in contrast to a reticulate pronotum and no long setae (in females). The original females were de- scribed from Japan on Magnolia kobus [ Magnoliaceae ], but specimens from China were collected from an unrelated deciduous broad-leaved tree species, Ulmus pumila [ Ulmaceae ]. The original description of the species indicated that the female has antennal segments II–V yellow, but specimens from China have segment II brown, at least clearly darker than III ( Fig. 45 ). The extent of the sub-basal pale areas on the fore wing are variable ( Figs 29 ). Female : Body brown with clear pale area ( Fig. 57 ), head brown with interocellar area pale, pronotum brown with four longitudinal light patches, mesonotum with pale patches posterolaterally ( Fig. 6 ), abdominal tergites V–VII laterally with annular pale areas, tergites VIII–X paler with brown patches. Fore wing brown with irregular sub-basal pale area and a small pale band in the middle ( Fig. 29 ). Antennae pale, segment I (or I–II), distal half of VI and VII–VIII brownish; segments III–IV with forked sense cones ( Figs. 45 ). Head with irregular reticles, ocellar setae III situated between hind ocelli; pronotum reticulate with inner wrinkles, mesonotum with transverse striae and metanotum with longitudinal reticles bearing wrinkles; tergites II–VIII posterolaterally with numerous tubercles in transverse lines ( Fig. 34 ); sternite VII with 3 pairs of setae in front of margin. FIGURES 32–37. Dendrothrips . Tergites 32–35: (32) diaspora IV–VI; (33) jeanneli IV–VI; (34) magnoliae IV–VII; (35) stannardi V–VII. Sternites 36–37: (36) jeanneli V–VII; (37) octosparsus sp. n . VI–VII. Male : Body including legs pale ( Fig. 58 ), head brown with occipital region paler; antennal segments I–V pale, VI–VIII pale brown ( Fig. 46 ); fore wing brown with 2 pale areas, sub-basally and sub-apically ( Fig. 30 ). Head smooth except occipital region sculptured with transverse reticles, ocellar setae pair III arising between hind ocelli. Antennae 8-segmented, segment VI with an incomplete suture; sense cones on III and IV small and U-shaped, sense cone on VI arising near middle of segment. Pronotum with transverse anastomosing striae bearing no internal markings, 3 pairs of posteromarginal setae prominent, 1 pair of posteroangular setae longest ( Fig. 7 ). Mesonotum with transverse anastomosing striae; metanotum longitudinally striate without markings. Abdominal tergites III–VIII laterally with transverse anastomosing lines bearing small tubercles, lines on tergite IX bearing microtrichia.
