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 : 402-404

Duffelsa grandia sp. n. ( Figs 4–5 , 8 )

Type material. Holotype: ♁ ( NWAFU), China: Nanxi Town , Hekou County, Yunnan Province, 27.IV.2013, coll. unknown . Paratypes: 4♁♁ ( NWAFU), China: Nanxi Town , Hekou County, Yunnan Province, 27.IV.2013, coll. unknown .

Measurements (in mm; 5♁♁). Body length: ♁46.8–47.4; forewing length: ♁49.5–50.7; forewing width: ♁11.1–12.0; width of head including eyes: ♁11.3–12.0; pronotum width (including pronotal collar): ♁12.2–13.1; mesonotum width: ♁11.1–11.9.

Etymology. The species name is a Latin masculine adjective, meaning “large”, signifying the large body size.

Description of male.

Head ( Fig. 4A–D ). Mostly greyish green. Eyes light yellow, with dense golden hair along posterior margin. Median black spot enclosing ocelli. Lorum with paired black markings. Anteclypeus with black patches laterally. Postclypeus prominent, transverse cross-section angular. Rostrum with apex blackish, extending to hind coxae.

Thorax ( Fig. 4A, C ). Pronotum almost greyish green; inner area of pronotum having no makings; pronotal collar symmetrically with and irregular black markings along inner margin of anterior area. Mesonotum fundamentally greyish green with the following black markings: discontinuous median arrow-shaped fascia reaching anterior margin of cruciform elevation; inwardly curved fascia along each parapsidal suture; paired spots on scutal depressions and paired markings on anterior angles of cruciform elevation.

Legs ( Fig. 4E ). Greyish green with brown patches. Fore femora with three brown spines beneath: primary spine slender, oblique to femur; secondary spine with acute tip; subapical spine short.

Wings ( Fig. 4A–B ). Hyaline. Forewing with longitudinal fuscous markings on apical cells, with distinct fuscous spots on transverse veins of apical cells 2, 3, 5, 7; and with marginal series of minute fuscous spots present on apices of longitudinal veins of apical cells. Hindwing has no markings.

Abdomen ( Figs 4A–D , 8C–D ). Cylindrical balloon, noticeably longer than head and thorax together, reddish brown with black markings on posterior margins of tergites. Timbal cover scale-like; timbal mostly concealed by timbal cover. Opercula upside-down triangular, widely separated and longer than wide, just extending beyond posterior margin of abdominal sternite II. Abdominal sternites mostly light reddish brown with red markings on posterior margins of sternites, with tubercle-like projections on centrolateral surface of abdominal sternite III. Abdominal sternite VIII oblong, with posterior margin narrowly emarginate at middle.

Genitalia ( Fig. 5A–E ). Pygofer elliptical in ventral view, ochraceous with apex blackish. Dorsal beak pointed, longer than anal styles. Distal shoulders broadly, distally extended into pointed lobe. Basal lobes small in lateral view, middle-upper part curved inward and placed laterally adjacent to side of pygofer in ventral view. Uncus trapezoid, dominant, bifurcated sub-basally, with two sub-lobes tapering apically and very slightly curved laterally in ventral view. Aedeagus long and slender, S-shaped, somewhat truncated at apex.

Distribution: China (Yunnan).

Remarks. This new species is similar to D. orientalis comb. n., but can be distinguished from D. orientalis comb. n. by the distinct bigger body and the forewing with distinct fuscous spots on transverse veins of apical cells 2, 3, 5 and 7.
