Macropsis irenae Viraktamath, 1981: 301
Macropsis irrorata Tishechkin, 2002b: 1331 (nec Matsumura, 1912: 307)
Description. Ochraceous (Figs. 13–14), scutellum with somewhat darker triangular markings on side angles. Forewings pale with dense brown dots forming visible wide transverse bands at the middle of clavus, at its end and in the apical parts of wings. Ends of claval veins and apex of clavus usually marked with brown.
Upper part of face (Fig. 28), pronotum and scutellum with prominent longitudinal carina.
Abdominal apodemes of 2nd tergite in male (Figs. 66–67) wide triangular, with tips slightly bent inwards. Apodemes of 2nd sternite (Figs. 68–69) of similar shape, with pointed tips.
The shape of penis (Figs. 83–84) and styles (Figs. 78–79) typical for group. Pygofer processes (Figs. 70–77) flat, twisted around longitudinal axes, with irregular serration in the middle of hind margin and with tips bent outwards in caudal view.
2nd valvulae of ovipositor (Fig. 86) with 3–5 preapical teeth.
Body length (including tegmina): ♂, 3.5–3.7 mm; ♀, 3.7–4.0 mm in specimens from China and Japan. Specimens from India and Nepal are somewhat smaller: ♂, 3.1–3.4 mm; ♀, 3.3–3.6 mm (Viraktamath, 1981)
Host. Quercus sp. (Viraktamath, 1981).
Material examined. China: 1 ♂, 1 ♀, Yunnan Province, Ailao Mt., 0 4. VI. 2011, collected by Zhang Xinfeng (GUGC). Japan: Honshu, Onnasawa, Nagano Pref., 21. VIII. 1962, Y. Miyatake, B.M. 1967-651; Kyushu, Tatsudayama, Kumamoto, 27. XII. 1957, T. Kawarabata, B.M. 1967-651; Kyushu, Fukuoka, Atagoyama, 26. VI. 1959, Y. Miyatake, B.M. 1967-651; Kyushu, Fukuoka Pref., Mt. Kanayama, 15. VI. 1958, Y. Miyatake, B.M. 1967-651, several specimens of both sexes (BM).
Distribution. India, Nepal (Viraktamath, 1981), China (new record), Japan (new record).
Remarks. The species is similar to M. meifengensis Huang & Viraktamath, 1993, but differs from it by having more irregular and less developed serrations along the pygofer process (Figs. 70–77). Investigation of drawings and photographs of the lectotype, paralectotypes and several more specimens of M. irrorata (Matsumura, 1912) from Japan showed that Tishechkin (2002b) misidentified M. irenae as M. irrorata.

Figs. 15–16, 29, 87–96
Material examined. Holotype: ♂, China, Guizhou Province, Leigong Mt., Miaoling, 0 6. VII. 2011, collected by Chang Zhimin (GUGC); paratype: 1 ♀, China, Guizhou Province, Fanjing Mt., Heiwanhe, 24. IX. 2011, collected by Fan Zhihua (GUGC).
Description. Body (Figs. 15–16) background color brown. Head and pronotum darker than forewings, cuticular striation distinct due to dark coloration. Face (Fig. 29) yellowish, with pale brown central area and dark striations; eyes brown, somewhat reddish; longitudinal cibarial muscle impressions inconspicuous. Scutellum yellowish except pale brown central part, with darker punctations. Forewings brown, with numerous dark brown speckles, more dense in areas of transverse veins and apical cells, appendix with a row of small dark brown spots. Legs yellowish, with scattered dark brown maculae.
FIGURES. 87–96. Macropsis latiprocessa sp. nov. 87—male abdominal apodemes of 2nd tergite; 88—male abdominal apodemes of 2nd sternite; 89—male pygofer and subgenital plate, lateral view; 90—male pygofer processes, caudal view; 91— style, dorsal view; 92—connective, dorsal view; 93—same, lateral view; 94—aedeagus, lateral view; 95—same, ventral view; 96—2nd valvulae of ovipositor.
External appearance (Figs. 15–16, 29) typical of group of oak-feeding species. Face, pronotum and scutellum with distinct dense striations and punctations and with longitudinal medial carina. Cibarial muscle impressions on face indistinct. Pronotum 2.5 times as wide as its middle length. Scutellum nearly 1.2 times as long as pronotum.
2nd tergal apodemes of male abdomen (Fig. 87) broad, longer than their width in middle, with tips truncated; 2nd abdominal apodemes of sternite (Fig. 88) triangular, basally widened and gradually tapered to pointed apices bent towards each other, distance between them slightly exceeds the length of apodemes.
Male pygofer (Fig. 89) in lateral view broad basally, dorsal and caudal margins incised, pygofer process (Fig. 89) short, not attaining to dorsal margin. In caudal view pygofer processes (Fig. 90) twisted outwards, widened and abruptly narrowed in distal half, with pointed apices. Subgenital plates (Fig. 89) rodlike, longer than ventral margin of pygofer. Styles (Fig. 91) long, abruptly bent in basal 0.38, tapering distally, apices slightly upturned. Connective (Figs. 92–93) stout, with long finger-like protrusion in middle, both lateral arms bent dorsally. Aedeagus (Figs. 94– 95) narrow in lateral view, distal half bent dorsally, apex rounded. In ventral view aedeagal shaft relatively stout, slightly tapered to rounded apex; gonopore apical on ventral margin.
Female similar to male in body shape and coloration. 7th sternite nearly triangular, in midline longer than 6th one, posterior margin with small depression in middle, ovipositor strongly projecting beyond pygofer. 2nd valvulae (Fig. 96) with 4 preapical teeth each.
Body length (including tegmina): ♂, 3.8 mm; ♀, 3.8 mm.
Host. Quercus spp. (Fagaceae).
Distribution. China (Guizhou Prov.).
Remarks. The new species is somewhat similar to M. rubrosternalis Kuoh, 1992 and M. sympatrica Viraktamath, 1996, but can be distinguished from M. rubrosternalis by the less sinuated, distinctly shorter, and differently shaped pygofer processes (Figs. 89–90), and the less abruptly bent aedeagal shaft (Figs. 94– 95) and from M. sympatrica in the shorter, outwardly twisted and broader pygofer process (Figs. 89–90).
Etymology. The new species name is derived from the Latin word “ lati- ”, refers to the broad pygofer process.
