Changbaninus, Fang & Xing, 2019

Fang, Yongqin & Xing, Jichun, 2019, A new Scaphoideini leafhopper genus from China (Hemiptera: Cicadellidae Deltocephalinae), with description of two new species, Zootaxa 4668 (3), pp. 435-442 : 435-436

Changbaninus gen. nov.

Type species: Changbaninus furcatus sp. nov.

Description. Body robust. Vertex with pair of irregular transverse stripes. Pronotum with irregular fuscous stripes. Face with frontoclypeus broadly yellowish brown dorsally, with dark transverse streaks on both sides. Forewings brownish, with scattered unpigmented areas, veins yellowish-brown. Hindwings macropterous. Legs dark brown.

Head distinctly narrower than pronotum. Vertex with fore margin produced roundly, median length shorter than width between eyes. Eyes large. Ocelli on anterior margin. Frontoclypeus distinctly longer than wide, anteclypeus expanded apically. Antennae are midhight of eye. Pronotum with anterior margin roundly produced and posterior margin concave, lateral margin carinate and slightly shorter than eye. Scutellum triangular, slightly shorter than pronotum, with transverse suture depressed. Forewing with four apical cells and three subapical cells, about 4 times as long as wide, appendix wide, vein R with all branches strongly reflexed, three or more supernumerary branches extended to costal margin, outer anteapical cell elliptical with short crossveins delimiting base and apex. Hindwing with three apical cells and two anteapical cells. Fore femur with 2 dorsoapical setae, row AM with 1 stout seta, row IC with 19 setae, and row AV with several short setae in basal half. Fore tibia with 5 macrosetae in row AD and numerous macrosetae decreasing in length toward the base in row AV. Hind femur broadened distally and slightly bowed, apical setal formula 2+2+1 or 2+2+1+1. Hind tibia flattened and nearly straight, row PD with 11 macrosetae decreasing in length toward base; row AD with approximately 10 long stout setae and 0–3 shorter stout setae between each long seta; metabasitarsomere with four platellae and two setae on apical transverse row.

Male genitalia. Male pygofer side longer than height, base wide, apex narrow, with few macrosetae on posterior area, not arranged in tufts. Valve short, subtriangular, posterior margin acute medially. Subgenital plate long, broad at base and gradually narrowed posteriorly, with one row of macrosetae along lateral margin. Connective Y-shaped, stem longer than arms, without processes. Style broad at base, abruptly narrowed before subapical lobe, apophysis either reaching or slightly exceeding apex of connective in situ. Aedeagus with pair of processes arising ventrolaterally from atrium and with pair of weakly sclerotized dorsal tendons extended from atrium to base of anal tube; aedeagal shaft tubular and spiculate at distal 1/2 to 1/3 length; gonopore subapical.

Remarks. Changbaninus gen. nov. resembles Longicornus Li & Song, 2008 externally, but can be distinguished from the latter by the long subgenital plates with entire apical margin (deeply concave near the apex in the latter genus), aedeagus with a pair of laterobasal processes and membranous dorsal connective, and the spiculate aedeagal shaft. The new genus is also similar to Scaphoidella Vilbaste, 1968 (e.g., S. undosa and S. wideaedeaga ) in general appearance, but can be distinguished from the latter by the male pygofer without processes, and the aedeagus with a pair of dorsal connectives. Changbaninus is placed in Scaphoideini based on the above mentioned similarities to other genera included in the tribe and agreement with the tribal diagnosis of Zahniser & Dietrich (2013).

Etymology. The generic name is an arbitrary combination of letters. The gender is masculine.

Distribution. Oriental Region ( China).
