Macropsis latiaedeagus Li, Dai et Li , sp. nov.

Figs. 19–21, 85–92

Material examined. Holotype: 3, China, Henan province, Taiping town, 31. VII. 2010, collected by Li Hu & Fan Zhihua; Paratype: 1 Ƥ, same data.

Description. Body emerald green (Figs. 19–21). Frons deep green. Face green, slightly yellowish, with brown discoidal spots and two small spots on clypellus. Eyes and ocelli brown. Spots on fore margin of pronotum and in side angles of scutellum distinct due to another tinge and smooth cuticle. Forewings hyaline, yellowish green. Legs green. In female coloration more deep green, with less distinct yellow tinge, body shape more stout.

2nd tergal apodemes in males very short, with sinuated or notched margins, 2nd sternal apodemes broad triangular, with inner margins parallel to each other (Fig. 86).

FIGURES. 77–84. Macropsis illota (Horvath) . 77—male pygofer and subgenital plate, lateral view; 78—male 2nd abdominal apodemes; 79—aedeagus, lateral view; 80—same, ventral view; 81—style, dorsal view; 82—connective, dorsal view; 83—same, lateral view; 84—2nd valvulae of ovipositor.

Pygofer broad, caudal margin straight, pygofer processes slender, almost straight, tips slightly bent back (Fig. 85). Subgenital plates slender, slightly expanded in apical half, with long marginal setae (Fig. 85). Aedeagal shaft in side view very broad, with nearly parallel margins, almost triangular in apical part, gonopore oval, situated in middle of distal half of shaft (Figs. 87–88). Styles slender, uniformly tapering distally, tips slightly expanded, upturned (Fig. 89). Connective stout, with a finger-like protrusion in middle, both lateral arms bend to dorsum (Figs. 90–91).

7th sternite in female triangular, along midline 2.5 times as long as 6th one, lateral margins distinctly concave, posterior margin with a notch. Ovipositor strongly projecting beyond pygofer, 2nd valvulae with 2 additional teeth each (Fig. 92).

Body length (including tegmina): 3, 4.0 mm; Ƥ, 4.1 mm.

Host. Willow ( Salix sp.).

Distribution. China (Henan prov.).

Diagnosis. The new species is similar to M. lijiangensis sp. nov. (see below), but can be distinguished from the latter one by aedeagal shaft is more broad in lateral aspect and more slender in ventral aspect, styles are distinctly tapering towards the tips and by another number of additional teeth on 2nd valvulae. Also differs from this species in body shape and coloration.

Etymology. The new species name is derived from the Latin words “ lati- ”and “ aedeagus ”, indicating that the aedeagal shaft is very broad in lateral aspect.
