Dendrothripoides moundi sp.n.

Female macroptera. Slide-mounted macerated females bicolored ( Fig. 1 ); head, pronotum, metanotum, first abdominal segment and legs pale yellow; abdominal segments II–X golden brown; antennal segments I–V yellow, VI mainly yellow but with apex brown ( Fig. 5 ), VII–VIII brown; fore wing with three white and two black areas as following: white at base also with white band distal to veinal fork and at apex, small dark marking near base and median area ( Fig. 6 ). Antennae 8-segmented, segments III and IV with forked sense cones, IV and V weakly pedicelate, III–VI rounded at each side ( Fig. 5 ). Ocellar setae III arising on lateral side of ocellar triangle, shorter than distance between hind ocelli ( Fig. 2 ). Pronotum ( Fig. 3 ) without distinct sculpture lines, with about 40 discal setae well-developed, posteroangular setae spatulate ( Fig. 3 ) with four pairs of posteromarginal setae. Mouth-cone long and stout, extending just beyond posterior margin of prosternum ( Fig. 3 ). Mesonotum with polygonal sculpture ( Fig. 4 ), without campaniform sensilla. Metanotum medially with polygonal sculpture, median pair of setae behind anterior margin; campaniform sensilla present ( Fig. 4 ). Fore wing first vein with 1 + 4 and 2 setae on distal third; clavus with 4 marginal setae and no discal setae. Abdomen relatively short and broad; segment X tubular, heavy, longitudinally grooved. Tergite I dorsally with 3–4 anastomosing transverse lines of sculpture; tergites II–VIII with conspicuous stout microtrichia about 8–10 microns long on triangular warts in about five rows, covering more than two-thirds of the dorsal aspect ( Fig. 9 ); II–VII with S1 setae shorter than S2 setae, 5 and 16 microns long respectively, posteromarginal setae (S3) stouter and curved, about 30 microns long, and on II–V setae S4 only about 20 microns long; tergite VIII with S1 setae almost as long as S2 setae; tergites IX and X with setae S1, S2 and S3 spine-like, long and dark ( Fig. 11 ). Sternites II–VII each with about 3 pairs of setae on posterior margin.

Measurements (holotype female, in microns). Body length 1233. Head, length 96; width across eyes 130; ocellar setae I 7, III 8; four pairs of postocular setae 12–13. Pronotum, length 114; width 195; posteroangular setae 34. Posteromedial setae 18; four pairs of posteromarginal setae 8–12. Fore wing length 471. Antennal segments I–VII length 16, 24, 38, 44, 30, 40, 10, 18. Tergite VIII S1 length 48, S2 55; tergite IX S1 length 111, S2 length 125, S3 length 101. Tergite X S1 length 92, S2 length 87, S3 length 101.

Male macroptera. Similar in structure to female but smaller and slender. Abdominal segments IX and X strongly sclerotized; tergite IX with median pair of short conical setae close to each other, and 3 pairs of small tubercles arranged laterally below median pair of setae; sternites III–VII each with a small transverse pore plate on middle of anterior margin ( Fig. 10 ).

Measurements (paratype male in microns). Body length 813. Fore wing 450. Pore plate dimensions on sternites III, IV and V: 23/6; 20/5; 23/4.

Type material. Holotype female, Kaominina , Moramanga , MADAGASCAR (lat: -18.94; lon: 48.41; elevation: 909.0 m.a.s.l.), on flowers of Lantana camara , 15.iv.2018 (Enric Frago) in the collection of insects of the Centre de Biologie pour la Gestion des Populations ( CBGP) Montpellier, France.

Paratypes: 7 females and 1 male with the same data as holotype in CBGP Montpellier , 1 female in Muséum national d’ histoire Naturelle, Paris.

Comments. This species is very similar to D. nakaharai but it differs from it in the colour of the fore wing, the sculpture of the metanotum, the position of the metanotal campaniform sensilla, and the size and shape of the male sternal pore plates.
