Sugea Jiao, Yang, Yan & Yu, 2024, gen. nov.

Genus. Sugea gen. nov. Fig. 1: A–P Type species. Sugea obtusangula sp. nov. Description. Body (Fig. 1: A, B) relatively large, center of crown (Fig. 1: C, D, F) with prominent bulge, coronal suture short, head in dorsal view narrower than pronotum. Face (Fig. 1: E) protuberant in profile, with well-defined angles at dorsal margin of frontoclypeus and midlength of anteclypeus, and clypeal sulcus distinct, anteclypeus strongly swollen and lorum very narrow in male (female unknown); ocelli vestigial, crescent-shaped. Pronotum (Fig. 1: C, D) with small angulate protrusion at center of anterior margin, with sublateral visible in frontal view. Mesonotum and scutellum depressed, forming single plane narrower than pronotum. Color of forewings relatively uniform, elliptical waxy area located near the middle of the outer margin of the forewing, 3rd apical cell (Fig. 1: G) small and stalked. Hind wing (Fig. 1: H) transparent, anal veins and CuA veins forked. Abdominal apodemes (Fig. 1: I, N) underdeveloped. Pygofer side (Fig. 1: J, O) broad but irregular in shape, ventral margin with indentations but without appendage. Subgenital plate (Fig. 1: J, O, P) longer than pygofer, not fused at base, with longitudinal row of sparse macrosetae, apex expanded with protuberances. Style (Fig. 1: L, M) elongate, without preapical lobe. Connective short and broad, V-shaped. Aedeagus (Fig. 1: L, M, P) with gonopore-bearing shaft greatly reduced, with pair of elongate basal processes. Gonopore apical. Distribution. China (Yunnan). Etymology: The new genus name is derived from the Chinese “Suge”, which symbolizes vitality and dynamism. Gender: feminine. Remarks: The new genus Sugea is similar to Igutettix Matsumura (1932), Vilbasteana Anufriev (1970), Sweta Viraktamath et Dietrich (2011), Koreoneura Hossain et Kwon (2021) and Cornicola Ohara et Hayashi (2022), in the comparatively large body-size and large pronotum. Some features of the pronotum, including the distinct submarginal furrow present along the anterior and lateral margins, and subgenital plates not fused to each other or to valve, show similarity to those of Sweta. But it is distinguished from Sweta by the black coloration, short and smooth pronotum, forewing with 3 rd apical cell small and with stalk, and hindwings CuA and anal veins forked. Moreover this new genus is characterized by the face with distinct angular features in profile, the less strongly raised center of the crown, pronotum with a small protruding angle at the center of the anterior margin and end of the subgenital plate with a horn-like protrusion. These traits distinguish it from other genera.
