Tan, Wei-Wen, Pu, Tian-Yi & Song, Yue-Hua, 2022, Two new species of the genus Tautoneura Anufriev from Karst area in Southwest China (Hemiptera: Cicadellidae: Typhlocybinae), Zootaxa 5195 (3), pp. 278-284 : 280

Tautoneura aureomarginalis Tan & Song , sp. nov.

Description: Body light yellow ( Figs 1, 2 ). Vertex, pronotum and scutellum with milky yellow markings or spots ( Figs 1, 3 ). Head yellowish, distinctly narrower than pronotum ( Figs 3, 4 ). Eyes black ( Figs 1, 2 ). Face milky white ( Figs 2, 4 ). Pronotum light yellow ( Fig. 3 ). Scutellum apex with black spot, basal triangles brownish yellow ( Figs 1, 3 ). Forewing with basal and commissural margin in basal half orange, few orange patches present on corium ( Figs 1, 2 ).

Abdominal apodemes short, not extended to posterior margin of 3 rd sternite ( Fig. 9 ).

Male genitalia. Pygofer lobe with few long setae and some microsetae at baso-lateral angle, numerous fine setae scattered on lateral surface ( Fig. 10 ). Pygofer dorsal appendage broadened at base, tapering towards apex ( Fig. 11 ). Anal tube appendage absent. Subgenital plate with 4 macrosetae near mid-length on lateral surface and some microsetae at sub-basal part, marginal subbasal microsetae forming continuous row near apex ( Fig. 12 ). Style slender, expanded slightly at subapex, preapical lobe prominent, apex tapered, without anteromedial angle ( Fig. 13 ). Aedeagal shaft depressed, curved dorsad and long, broad in posterior view with two pairs of processes apically and subapically, subapical pair extended dorsolaterad and crossing apical pair; gonopore on ventral surface preapically ( Figs 14, 15 ). Aedeagus dorsal apodeme obvious, about half length of aedeagal shaft; preatrium developed but short ( Figs 14, 15 ). Connective stem absent, median lobe very short ( Fig. 16 ).

Measurement. Male length 2.9–3.0 mm (including wing).

Specimens Examined. Holotype ♂: China, Guizhou Prov., Huajiang Town , 30 May 2021, coll. Jia Jiang. Paratypes: one ♂, same data as holotype .

Remarks. This species is similar to T. formosa Dworakowska (1970) , but can be distinguished by the depressed aedeagus (broader in posterior view than in lateral view) with very short preatrium ( Figs 14, 15 ) and forewing with commissural margin orange ( Figs1, 2 ).

Etymology. The specific name combines the Latin words “ aureo ” and “ marginalis ”, which refers to the orangebordered forewing.
