Figs. 7–12, 25–27, 49–65

Material examined. Holotype: ♂, China, Shaanxi Province, Meixian, Taibai Mt., 18. VII. 2012, collected by Yu Xiaofei ( GUGC); paratypes: 1 ♂, 1 ♀, China, Shaanxi Province, Ningshan County, Huoditang, 12. VII. 2012, collected by Li Hu and Yang Weicheng ( GUGC); 1 ♂, China, Yunnan Province, Dali City, Cang Mt., 14. VIII. 2012, collected by Fan Zhihua ( GUGC).

Description. Body background color (Figs. 7–12) yellowish brown. Head and pronotum yellowish brown with darker striations on surface. Face (Figs. 25–27) yellowish, with upper part darker, lower region lighter, striations of same color as surrounding areas; eyes red brown; longitudinal cibarial muscle impressions inconspicuous. Hind margin of pronotum sometimes yellowish. Scutellum usually yellow with darker speckles and pale brown lateral corners. Forewings brown, with numerous dark brown speckles throughout except two hyaline areas in central part, ends of claval veins marked with dark brown, veins of apical cells dark brown, appendix with a row of dark brown spots. Legs yellowish, with dark brown bases of macrosetae on hind tibia.

Body form (Figs. 7–12) typical of group feeding on oak. Head including eyes as wide as pronotum, crown distinctly shorter medially than laterally. Head, face, pronotum and scutellum with dense striations and punctations, somewhat indistinct because of same color as surrounding areas. Medial longitudinal carina on face, pronotum and scutellum distinct. Traces of cibarial muscle impressions on face distinct due to smooth surface. Distance between ocelli five times as great as that from ocellus to adjacent eye. Pronotum with dense and oblique striations, frontal margin strongly produced forward, hind margin clearly excavated medially, about 2.1 times as wide as its middle length. Scutellum nearly triangular, slightly longer than pronotum.

2nd abdominal tergal apodemes in male (Fig. 49) well developed, longer than wide in middle, with tips rounded and inner margins sinuated; 2nd abdominal sternal apodemes (Fig. 50) triangular, broad basally and gradually tapering to pointed apices, bent inwards, gap between apodemes nearly equal to their length.

Male pygofer (Fig. 51) in lateral view broad basally, dorsal margin oblique, caudal margin strongly concave, with membranous region. Pygofer process (Figs. 51–53) as a rule slightly sinuated, relatively thick and long, almost attaining dorsal margin, with parallel margins and bluntly rounded apex; in caudal view, pygofer processes (Figs. 54–56) somewhat sinuated and slightly expanded in apical half, with pointed tips. Subgenital plates (Fig. 51) FIGURES. 49–65. Macropsis huangbana sp. nov. 49—male abdominal apodemes of 2nd tergite; 50—male abdominal apodemes of 2nd sternite; 51—male pygofer and subgenital plate, lateral view; 52–53—male pygofer processes, lateral view (from two specimens); 54–56—same, caudal view (from three specimens); 57—style, dorsal view; 58–59—connective, dorsal view (from two specimens); 60—same, lateral view; 61–63—aedeagus, lateral view (from three specimens); 64—same, ventral view; 65—2nd valvulae of ovipositor.

of typical shape. Styles (Fig. 57) slender, abruptly bent in basal 0.43, gradually tapering distally, with slightly reflexed tips. Connective (Figs. 58–60) stout, with broad fingerlike protrusion in middle, both lateral arms twisted to dorsum. Aedeagus (Figs. 61–64) comparatively narrow in lateral view, abruptly upturned dorsally in distal 1/3, slightly tapered, with rounded apex; in ventral view shaft more slender, with parallel lateral margins and rounded apex; gonopore apical on ventral margin.

Female in body coloration and appearance similar to male. 7th sternite triangular, in midline longer than that of 6th one, lateral margins oblique, posterior margin with small depression in middle, ovipositor strongly projecting beyond pygofer. 2nd valvulae (Fig. 65) with 6 preapical teeth each.

Body length (including tegmina): ♂, 4.8–5.0 mm; ♀, 4.9 mm.

Host. Quercus spp. ( Fagaceae ).

Distribution. China (Shaanxi and Yunnan Provs.).

Remarks. Coloration intensity varies among specimens examined, with the body background color more or less darker or lighter (Figs. 7–12); the length of male pygofer process also varies slightly (Figs. 51–56).

The new species resembles M. emeiensis Li & Liang, 2005 and M. ceylonica Viraktamath, 1981 , but can be distinguished from both species by the sinuated pygofer process (Figs. 51–56), and different tortuosity and shape of aedeagal shaft (Figs. 61–63).

Etymology. The new species name is derived from the pinyin of Chinese characters, huangban, indicating the yellowish scutellum.
