Aduncothrips huapingensis sp.n.

( Figs 18–28 )

Female macroptera. Body uniformly dark brown ( Fig. 18 ); antennal segments I–II dark brown with apex of II yellow, III–V pale with apex brown, VI–IX brown ( Fig. 21 ). Fore wings with two longitudinal dark bands which along anterior and posterior margins toward apex, clavus uniformly dark brown ( Fig. 20 ). All legs dark brown, with tibiae and tarsi pale, tibiae on fore leg and middle leg dark brown basally, and tibiae on hind leg with base and apex brown ( Fig. 26 ); prominent body setae dark. Head longer than wide, with close transverse striae on dorsal surface, postocular setae irregularly arranged; maxillary palp segment II subdivided ( Fig. 24 ). Antennal segments III–IV with vermicular sensorium and curving around apex, internal markings present. Pronotum longer than wider, sculptured with dense transverse striae, with more than 50 discal setae,3 pairs of posteromarginal setae subequal to discal setae, except for S1 longer and stouter. Mesonotum closely sculptured with transverse striate, with small wrinkles between sculpture lines; lateral and posteromedian setae short and stout; anteromedian CPS absent ( Figs.22–23 ). Metanotum with lateral elongate narrow and posteromedian short reticulations, reticulations centralized as an inverted triangleshaped area, anteromedian area with transverse sculpture lines, with small wrinkles between sculpture lines; median pair of setae near posterior margin, submedian pair at anterior margin, CPS absent ( Figs. 22–23 ). Abdominal tergite I with transverse lines; tergites II–VIII with transverse striae, weakly medially; Sternites II–VI with 3–5 pairs posteromarginal setae, VII with 7 pairs and submarginal on V–VII; all sternites with discal setae, II–V with 3–4 pairs, VI with 5 pairs, VII with 6 pairs, VIII with 4 pairs ( Fig. 25 ).

Measurements (holotype in microns). Body length 1909; head length 190, width 154. Pronotum length 216, width 186. Fore wing length 893, median width 113. Antennal segments I–IX length: 31, 45, 96, 89, 48, 39, 36, 12, 11.

Male macroptera. Similar to female but smaller and paler. Maxillary palps 3-segmented and segment II undivided ( Fig. 28 ). Abdominal tergites with transverse striate sculpture, tergite I with two longitudinal ridges, IX without tubercles and claspers. Sternites II–VII with 3 pairs of posteromarginal setae, IV–VII with 2–4 discal setae, VIII with 4 pairs of posteromarginal setae and 4–6 discal setae.

Measurements (paratype in microns). Body length 1374; head length 145, width 150. Pronotum length 154, width 135. Fore wing length 677, median width 71. Antennal segments I–IX length: 26, 44, 86, 84, 48, 39, 28, 13, 7.

Specimens studied. Holotype: female, CHINA, YUNNAN Province, Huaping County, on mango, 20.iii.2010 (Yonghui Xie) . Paratypes: 1 female & 2 males collected with holotype .

Etymology. This species is named after collecting place.

Comments. This species can be distinguished easily from other members of Aduncothrips by the fore wings with two longitudinal dark bands, along the anterior and posterior margins toward apex. This character is similar to the recent redescription A. asiaticus ( Rachana et al. 2020) , but in A. asiaticus the longitudinal dark band on the fore wings is only along the posterior margin, moreover the metascutal striae form a triangle medially ( Fig. 23 ), and the hind tibia is bicolored. It is the only species with the sense cones on antennal segments III–IV completely encircling the apex and in IV form a necktie structure.
