Macropsis longiprocessa Li & Tishechkin sp. nov.

Figs. 17–18, 30, 97–106

Material examined. Holotype: ♂, China, Yunnan Province, Lanping, Lajin, 03–04. VIII. 2012, collected by Long Jiankun (GUGC); paratypes: 1 ♂, 1 ♀, same data as holotype (GUGC).

Description. Body (Figs. 17–18) background color dark brown. Head and pronotum dark brown, striations on surface darker. Face (Fig. 30) yellowish, with darker punctation; eyes pale brown; longitudinal cibarial muscle impressions conspicuous, without punctations. Scutellum usually yellow brown, with darker speckles and brown lateral corners. Forewings dark brown, with numerous dark brown speckles throughout entire surface except two hyaline spots in central area. Ends of claval veins with black spots, appendix with row of dark brown spots. Legs yellowish.

2nd abdominal apodemes in male (Fig. 97) weakly developed, tergal apodemes (Fig. 98) short and rounded, sternal apodemes triangular, gradually tapering to pointed apices, bent towards each other, the gap between their bases nearly twice as long as apodeme.

External appearance (Figs. 17–18) typical of group. Face, pronotum and scutellum with distinct dense striation and punctation and with longitudinal medial carina. Lateral regions of cibarial muscle impressions on face slightly depressed. Pronotum 2.3 times as wide as its middle length. Scutellum nearly 1.5 times as long as pronotum. In other characters similar with M. huangbana sp. nov.

Male pygofer (Fig. 99) in lateral view broad basally, dorsal margin incised, caudal margin slightly concave, with membranous region, pygofer process long, slightly sinuated, exceeding beyond dorsal margin, directed caudodorsally, with slightly expanded apical half and pointed apex. In caudal view pygofer processes (Fig. 100) clearly sinuated and directed dorsally. Styles (Fig. 101) stout, angled on basal 0.40, gradually tapering distally, with slightly reflexed tips. Connective (Figs. 102–103) of typical shape. Aedeagus (Figs. 104–105) narrow in lateral view, bent dorsally in distal half, 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 external appearance similar to male. 7th sternite nearly triangular, in midline longer than that of 6th one, posterior margin with small depression in middle, ovipositor strongly projecting beyond pygofer. 2nd valvulae (Fig. 106) with 3–4 (3 on the one and 4 on the other one) preapical teeth each.

FIGURES. 97–106. Macropsis longiprocessa sp. nov. 97—male abdominal apodemes of 2nd tergite; 98—male abdominal apodemes of 2nd sternite; 99—male pygofer and subgenital plate, lateral view; 100—male pygofer processes, caudal view; 101—style, dorsal view; 102—connective, dorsal view; 103—same, lateral view; 104—aedeagus, lateral view; 105—same, ventral view; 106—2nd valvulae of ovipositor.

Body length (including tegmina): ♂, 4.6–4.7 mm; ♀, 4.6 mm.

Host. Quercus spp. (Fagaceae).

Distribution. China (Yunnan Prov.).

Remarks. The new species resembles M. brunomaculata Huang & Viraktamath, 1993, but can be distinguished from the latter by the larger body size and long pygofer process (Figs. 99–100) directed caudodorsally.

Etymology. The new species name is derived from the Latin word “ longi- ”, indicating that this species has long pygofer process.
