Meng, Ze-Hong & Yang, Mao-Fa, 2015, A new genus and species of Cicadellini (Hemiptera: Cicadellidae) from China, Zootaxa 4039 (3), pp. 489-494 : 493

Biprocessa shielda sp. nov. ( Figs 14–21 )

Type-locality: Yunnan ( China)

Description. Length. ♂, 7.2–7.6mm.

Coloration. Body yellow. Vertex with a small round black spot; between ocelli with large shield-shaped black spot; ocelli with circled black markings; eyes black. Mesonotum with basal angles with black spot. Forewing with apical membrane infuscate. Legs with tarsi apices dark brown.

External features. Head with anterior margin roundly produced. Ocelli equidistant between each other and adjacent eye. Other features as in generic diagnosis.

Male genitalia. Pygofer ( Fig. 15 ) narrowed apically, posterior margin nearly oblique, posterodosal margin nearly angulate, dorsal margin concave near apex; disk with macrosetae mostly on median and apical portion; pygofer process with apical 3/4 bent dorsally. Subgenital plates ( Fig. 16 ) with apical half curved dorsally. Aedeagus ( Figs 17 and 18 ), in ventral view broad and short; in lateral view, arched and nearly S-shaped, basal process short. Paraphysis ( Figs 17–19 ) slender, in ventral view, slightly constricted medially, apical margin slightly concave medially, apical lateral projections developed. Connective ( Fig. 20 ) Y-shaped with lateral margins straight. Style ( Fig. 21 ) not exceeding posterad as far as apex of connective.

Female genitalia. Unknown.

Material examined. Holotype, male, China, Yunnan Province, Gaoligongshan, 4 to 5 June 2009, coll. Yang Zai-hua and Li Bin. Paratype, 1 male, same data as holotype.

Etymology. This new species is named for shield-shaped black spot of the crown.

Remarks. This new species is similar to B. jiaoi ( Yang & Li, 2005) . It differs in having a black spot between the ocelli ( Fig. 14 ), the pronotum ( Fig. 14 ) without a median black spot, the male pygofer ( Fig. 15 ) with posterior margin oblique and distinct concavity on the dorsal margin, the paraphysis ( Figs 18 and 19 ) with apex broader, and the aedeagus ( Fig. 17 ) S-shaped and without a long basidorsal process.
