Simaonukia Li & Li gen. n.

Type species.

Simaonukia longispinus sp. n.

Description.

Body medium-sized, usually black. Head (Figs 1, 4) in dorsal view narrower than pronotum; with five distinct carinae, a median carinae, two lateral carinae and two subocellar carinae converging to apex of vertex, area between median carina and submarginal carina with many fine longitudinal wrinkles; disc with a short transverse ridge basally, carinate. Front of head (Figs 1, 4) slightly conically produced; vertex about as long as or a little longer than pronotum and nearly two times longer and three times wider than eye. Ocelli (Figs 1, 2, 4, 5) placed just laterad of lateral carina, well in front of eye. Face (Fig. 3) including eyes shorter than wide; frontoclypeus (Figs 2, 3, 5) tumid, with median longitudinal carina strongly elevated; clypellus broad and swollen at base; lora nearly reaching middle of clypellus. Pronotum (Figs 1, 4) with sides strongly convergent cephalad. Scutellum (Fig. 1) with transverse depression distinct. Hind femur (Fig. 11) with apical macrosetal formula 2+1+1. Forewing (Figs 1-3) with R1a present; with four apical cells and two closed subapical cells; appendix very narrow.

Male genitalia. Pygofer without ventral process, triangular in lateral view, with some small setae on ventral side near apex. Subgenital plate ligulate with many macrosetae and long fine setae ventrally. Aedeagal shaft short with pair of lamellae dorsally near base and pair of lateral processes subbasally. Style short, foot-like apically. Connective similar in length to style, arms very short.

Distribution.

China (Yunnan).

Etymology.

The genus name is formed from a combination of the collection locality and the similar evacanthine genus Onukia Matsumura.

Remarks.

This genus can be distinguished by the moderately conically produced head with five distinct longitudinal carinae and dense striations and a transverse carinate ridge basally on disk. In the key to genera by Wang et al. (2015) the new genus runs to Onukia Ishihara but can be distinguished by: 1) Aedeagus (Figs 8-10, 13-15) with a pair of lateral processes subbasally; 2) Pygofer (Fig. 6) without processes.
