Idiocerus serratastylus sp. nov.

Fig. 3

Description. Small-sized species. Body length (including forewing): male, 4.1–4.2 mm, female, 4.1–4.4 mm.

Coloration. General color ( Fig. 3A–C ) ochraceous. Crown and pronotum yellowish, eyes dark brown to black. Pronotum posterior margin with ochraceous broad band. Forewings ( Fig. 3A, C ) with two yellowish patches on clavus, black apically. Legs ( Fig. 3C ) green.

Wing venation. Forewing with only middle anteapical cell closed.

Male genitalia. Pygofer ( Fig. 3D ) ventral margin slightly concave. Male valve ( Fig. 3E ) basal margin not curved, apex convex medially, with notched median projection. Subgenital plate ( Fig. 3D ) bent dorsad at right-angle near midlength. Connective ( Fig. 3F ) wide and short. Style ( Fig. 3G ) slightly bent, base expanded, medial margin serrated subapically. Aedeagal shaft ( Fig. 3H, I ) cylindrical, uniform from base to subapex, with pair of long, thin, curved subapical processes, apex flat and slightly broadened in posterior view.

Measurements (mm). Male: body length 4.10–4.20, face length 1.20–1.30, width 1.30–1.40; distance between ocelli 0.20–0.30; distance from ocellus to eyes 0.30–0.40; medial length of pronotum 0.35–0.40, width 0.68–0.72; scutellum length 0.80–0.90, width 0.53–0.56.

Type material. Holotype, ♂, Baoshan City , Mt. Gaoligongshan, Yunnan Province, China. (98° 48′ 03″ E, 25° 18′ 16″ N; H: 1581 m), 26 May 2019, coll. Xianyi Wang & Qin Zuo. Paratypes, 5♂♂ 4♀♀, same information as holotype. (No. IDW20005) .

Remarks. The new species can be distinguished from other species of the genus by the obviously serrate style, and aedeagal shaft with two slender subapical processes.

Host plant. Unknown.
