Material examined.
Holotype, ♀, China, Xizang, Zhangmu, taken on leaves of unknown plant, viii.2013, Jianfeng Wang (SNUT); paratypes, 2♀ 1♂, with same data as holotype (SNUT); 2♀ 1♂, Yunnan, Dali , on leaves of unknown plant, viii.2009, Lixin Su (SNUT).
Description.
Holotype. Female macroptera. Body brown; all femora and tibiae brown, fore tarsi clear yellow, mid and hind tarsi brownish, slightly lighter than tibiae; antennal segments I and II brown, III clear yellow, IV-VI yellow but shaded on apical half, VII and VIII brown (Fig. 10 View Figures 8–13 ); major setae pale; fore wing slightly greyish.
Head. Head ~ 1.3 × as long as wide (Fig. 3 View Figures 2–7 ), constricted at base; postocular setae pointed or slightly blunt at apex, approx. as long as eyes (Fig. 3 View Figures 2–7 ); eyes equal in length ventrally and dorsally; maxillary stylets V-shaped, retracted to median of head; mouth cone long, reaching to posterior margin of basantra. Antennal segments broad (Fig. 10 View Figures 8–13 ), segment III ~ 2.1 × as long as apical width; III with three sense cones, IV with four major sense cones, VIII constricted at base.
Thorax. Pronotum with five pairs of setae, slightly blunt at apex, am and aa approx. equal in length (Fig. 3 View Figures 2–7 ), epim and pa longer and equal in length; surface almost smooth, with weak sculpture near margins. All legs slender, fore tarsi with minute and scarcely visible tooth (Fig. 13 View Figures 8–13 ). Fore wing with three sub-basal setae arising in straight line, S1 and S2 equal in length, blunt at apex, S3 slightly longer, acute at apex, with eight duplicated cilia. Mesonotum transversely reticulate, lateral setae well developed, blunt at apex. Metanotum longitudinally reticulate, major setae slender and acute (Fig. 14 View Figures 14–25 ). Mesopresternum with paired lateral triangles, metathoracic sternopleural sutures absent.
Abdomen. Pelta broadly triangular, reticulate, with pair of CPS; tergites II-VII with two pairs of major wing-retaining setae, one pair of accessory sigmoid setae located anterior to first pair; tergite II with eight pairs of lateral setae; tergite IX setae S1 and S2 longer than tube, acute at apex, S3 approx. as long as tube, acute at apex; tube shorter than head, anal setae shorter than tube.
Measurements (holotype female in μm). Body length 2820. Head length (maximum width) 250 (190); distance between maxillary stylets (across bridge) 115; eye length dorsally 90; postocular setae length 90; antennal segments I-VIII length (width): 45 (35), 50 (35), 75 (35), 75 (40), 65 (30), 60 (25), 55 (25), 35 (15); sense cone on III length 30. Pronotum length (width) 190 (270); am 40, aa 45, ml 60, epim 100, pa 100. Fore wing length 1160; sub-basal setae S1 90, S2 90, S3 110. Tergite IX setae S1 270, S2 240, S3 180; tube length 220, basal width 75, apical width 50; anal setae length 220.
Male macroptera. Similar to female in colour and sculpture; fore tarsal tooth scarcely visible; fore wing with ~ 9 or 10 duplicated cilia; abdominal tergite IX setae S2 small and pointed; sternite VIII without pore plate.
Measurements (paratype male in μm). Body length 2460. Head length (maximum width) 240 (175); eye length dorsally 85; postocular setae length 75. Pronotum length (width) 170 (230); am 35, aa 30, ml 40, epim 80, pa 85. Tergite IX setae S1 205, S2 25, S3 220; tube length 190; anal setae length 190.
Etymology.
The species epithet refers to one of the collectors, Jianfeng Wang (Shenyang University).
Comments.
This species is closely related to M. longistylus sp. nov., but it can be distinguished by the short V-shaped maxillary stylets (Fig. 3 View Figures 2–7 ). The third new species described here, M. vernicia sp. nov., also has short stylets (Fig. 4 View Figures 2–7 ), but M. jianfengi sp. nov. can be differentiated in antennal segment III with 3 sense cones (Fig. 10 View Figures 8–13 ).
