Wang, Jiali, Jiang, Jinyuan & Wei, Cong, 2023, A new genus, Duffelsa gen. n., with descriptions of three new species and one new combination (Hemiptera: Cicadidae), Zootaxa 5323 (3), pp. 396-408 : 404-406

Duffelsa rubida sp. n. ( Figs 6–8 )

Type material. Holotype: ♁ ( NWAFU), China: Hekou County, Yunnan Province, 27.IV.2013, coll. unknown . Paratype: 1♁ ( JJPC), China: Hudie Village , Jinping County, Yunnan Province, 19.IV.2023, coll. Minming Pu.

Measurements (in mm; 1♁). Body length: ♁46.1–47.2; forewing length: ♁51.5–52.1; forewing width: ♁16.5–17.1; width of head including eyes: ♁11.6–12.0; pronotum width (including pronotal collar): ♁13.9–14.5; mesonotum width: ♁12.9–13.2.

Etymology. The species name is a Latin masculine adjective, meaning “rubescent”, signifying the mesonotum changing to reddish brown after death.

Description of male.

Head ( Figs 6A–D ). Mostly reddish brown. Eyes blackish brown, with dense golden hair along posterior margin. Black markings along frontoclypeal suture and median black spot enclosing ocelli. Lorum with paired black markings. Anteclypeus with black patches laterally. Postclypeus prominent, transverse cross-section around. Rostrum with apex blackish, extending to hind coxae.

Thorax ( Figs 6A, C ). Pronotum almost reddish brown; pronotal collar symmetrically with and irregular black markings along inner margin of anterior area, and with paired black spots on posterolateral area. Mesonotum fundamentally reddish brown with the following black markings: median arrow-shaped fascia reaching anterior margin of cruciform elevation; inwardly curved fascia along each parapsidal suture; interrupted fascia along the laterally of each parapsidal suture; paired spots on scutal depressions and paired markings on anterior angles of cruciform elevation.

Legs ( Fig. 6E ). Ochraceous with brown patches. Fore femora with three brown spines beneath: primary spine slender and erect; secondary spine short, triangular with rounded apex; subapical spine small.

Wings ( Figs 6A–B ). Hyaline. Forewing with longitudinal fuscous markings on apical cells, with distinct fuscous spots on transverse veins of apical cells 2, 3; and with marginal series of minute fuscous spots present on apices of longitudinal veins of apical cells. Hindwing has no markings.

Abdomen ( Figs 6A–D , 8E–F ). Cylindrical balloon, noticeably longer than head and thorax together, reddish brown with black and red markings on posterior margins of tergites.Timbal cover scale-like; timbal mostly concealed by timbal cover. Opercula convex, upside-down triangular, widely separated and longer than wide, extending beyond posterior margin of abdominal sternite II. Abdominal sternites mostly light brown, with tubercle-like projections on centrolateral surface of sternite III. Abdominal sternite VIII relatively narrow, with posterior margin rounded.

Genitalia ( Fig. 7A–E ). Pygofer elliptical, light brown with apex blackish. Dorsal beak pointed, longer than the anal styles. Distal shoulders broadly, distally extended into pointed lobe. Basal lobes large in lateral view, basally curved inward and placed laterally adjacent to side of pygofer in ventral view. Uncus with median lobe bifurcated sub-basally, with the two sub-lobes meeting at inner margins in ventral view. Aedeagus J-shaped, with distal onethird remarkably curved in lateral view.

Distribution: China (Yunnan).

Remarks. This new species is similar to D. grandia sp. n. but can be distinguished from the latter by the rounded transverse cross-section of postclypeus, the paired markings of frons, the paired black spots on posterolateral area of pronotal collar, the relatively large basal lobes of pygofer (in lateral view), and the two connected sub-lobes of median lobe of uncus.
