Zhang, Yalin, Gao, Xia & Huang, Min, 2011, Two new species of Yangisunda Zhang (Hemiptera: Cicadellidae: Typhlocybinae: Zyginellini) from China, with a key to species, Zootaxa 3097, pp. 45-52 : 49

Yangisunda bisbifudusa sp. nov.

Figs 4–6, 15–23

Description. Body yellowish, eyes black, vertex, pronotum, scutum and scutellum yellowish (Figs. 4, 5). Anterior part of face white, the rest yellowish (Fig. 6). Forewing semitransparent, yellowish, hind margin of brochosome field with oblique brown stripe, apical margin broadly bordered with brown area, third apical cell long and narrow, spot in it is smaller than in Y. apicibicruris sp. nov. (Figs. 4, 5).

Abdominal apodemes parallel-sided, slightly exceeding fifth sternite ( Fig. 15 ).

Male pygofer with fingerlike process dorsally, directed dorsocaudad; lateral and ventral margin of pygofer with few slim microsetae but without macrosetae ( Fig. 19 ). Subgenital plates with one macroseta in basal part, apical part curved gradually dorsad, with two short lobes, one is short and fingerlike, other one cylinderical, both with few microsetae ( Figs. 17, 18, 19. 21 ). Paramere ( Fig. 20 ) and connective ( Fig. 16 ) as described for genus. Aedeagus with developed dorsoatrium, base of each aedeagus process with one branch longer, other divided into two subbranches of nearly similar length; gonopore apical ( Figs. 22, 23 ).

Body length. 32.60–2.70 mm (including wing).

Material examined. Holotype, 13, China: Fujian Prov., Mt. Wuyi, Huanggang, 16 Aug. 2008, coll. Gao Xia, Li Xiaoting. Paratypes, 53, China: Fujian Prov., Mt. Wuyi, Tongmucun, 3 Aug. 2009, coll. Cao Yanghui.

Distribution. China (Fujian)

Remarks. The new species resembles Y. parachoui , but differs in lacking macrosetae on the pygofer ( Fig. 19 ) and in having the outer branch of the aedeagal processes much longer ( Figs. 22, 23 ), while in Y. parachoui , the pygofer has macrosetae ( Fig. 30 ) and the outer branch of the aedeagal processes is very short ( Figs. 31, 32 ).

Etymology. The specific epithet is derived from the Latin prefix “ bis -” meaning “again”, and the Latin word “ bifudusa ” meaning divided into two branches, referring to the aedeagus shaft with apical process being divided into two branches near base, then one of them branching into two again.
