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 : 436-437

Changbaninus furcatus sp. nov.

Figs. 1–17

Description. Vertex yellowish with some black stripes. Eyes black. Pronotum with irregular yellowish brown stripes. Scutellum with pair of yellowish white spots at lateral margin of midlength ( Figs. 1, 3 ). Hind femur apical setal formula 2+2+1 ( Fig. 4 ).

External features as in generic description.

Male genitalia. Male pygofer side length about 2 times high ( Fig. 5 ). Subgenital plate very long, about 6 times as long as wide at base, with 10 long macrosetae along lateral margin, apex slightly sclerotized ( Figs. 6, 7 ). Aedeagus with a pair of furcate laterobasal processes, nearly 1/3 as long as aedeagal shaft, and aedeagal shaft spiculate in apical region; ( Figs. 8, 9 ). Connective with arms nearly 1/2 length of stem ( Fig. 10 ). Style apophysis well-developed, slightly enlarged subapically ( Fig. 11 ).

Female seventh sternite twice as long as broad at base, caudal margin medially produced with a notch in the middle ( Fig. 12 ). Female pygofer with ventroposterior margin slightly incurved. ( Fig. 13 ). First valvula of ovipositor sculpture strigate ( Figs. 14, 15 ). Second valvulae more curved than the first, denticulate area confined to distal 1/3, denticles prominent, gradually becoming smaller distally, apex pointed ( Figs. 16, 17 ).

Measurement. Length (including tegmen): Ƌ, 7.9–8.3mm; ♀, 8.2–8.4 mm.

Type material. Holotype: ³, China: Guizhou Prov., Leigongshan , 2 July 2011, coll. Jiankun Long ( GUGC) ; Paratypes: 2³³ 3♀♀, Guizhou Prov., Leigongshan , 2 July 2011, coll. Jiankun Long and Zhiming Chang ( GUGC) .

Remarks. This new species is similar to Changbaninus pleiospicules sp. nov., but can be distinguished from the latter by the furcate laterobasal processes of the aedeagus and aedeagal shaft spiculate near apex.

Etymology. The new species is derived from the Latin word “ furcatus ”, referring to the aedeagal shaft with a pair of furcate processes.
