Jiao, Meng, Yang, Maofa, Yan, Bin & Yu, Xiaofei, 2024, A new genus of tribe Dikraneurini (Hemiptera: Cicadellidae: Typhlocybinae) from China based on a new species and genus checklist from China provided, Zootaxa 5543 (1), pp. 135-140 : 136-137

Sugea obtusangula gen. et sp. nov.

Fig. 1 : A–P

Description. Length: male 4.2–4.5 mm.

Body ( Fig. 1 : A, B) black with white spots, four white spots surround the central protrusion of crown ( Fig. 1 : F); eyes brown. Face ( Fig. 1 : E) black, postclypeus and anteclypeus relatively pale, antennae yellow. Front and postclypeus separated by distinct transverse ridge, most evident in lateral view. Pronotum ( Fig. 1 : C, D, F) black with white spots located at depressions near lateral margins. Lateral angles and apical angle of scutellum black, central part yellow, and area near transverse depression black.

Forewing ( Fig. 1 : G) black, middle of claval area, with two slanted white stripes, and white patch at apex. Area along the R and M veins red. First apical cell large, occupying about half of apical area, third apical cell small with stalk. Abdominal apodemes ( Fig. 1 : I, N) extended to 4th abdominal sternite. Pygofer side ( Fig. 1 : J, O) covered with truncate setae, heavy sclerotization distributed along notches of ventral margin.

Subgenital plate ( Fig. 1 : J, O, P) long and upturned with scattered large setae along ventral margin, apex expanded laterad, with sclerotized horn-like protrusion at top of expanded section. Style ( Fig. 1 ; L, M) longer than aedeagus, slightly sinuate. Connective ( Fig. 1 : L, M) shorter than wide. Aedeagus ( Fig. 1 : L, M, P) broad at base, atrial complex enclosing shaft, shaft short and tubular, curved, pair of curved short protrusions at base and a pair of long protrusions at the end; long protrusions slender and crossing each other, comprising about two-thirds of total length of aedeagus.

Type material. Holotype, 1♂, CHINA: Yunnan Province, Lvchun. 102.4251°E 22.9432°N, 2075m, 8.V.2015, (light-trap), collected by Wu Yunfei. Paratype, 5♂♂, same data as holotype

Etymology. The specific epithet is the Latin word obtusangula referring to the angulate profile of the face.

Remarks. Unusual characteristics of this new species include the sclerotization distributed along the notches of the pygofer ventral margin and the aedeagus with well-developed processes but the shaft short and tubular.
