Song, Yuehua & Li, Zizhong, 2008, Notes on Chinese species of the genus Tautoneura Anufriev (Hemiptera: Cicadellidae: Typhlocybinae), with descriptions of two new species, Zootaxa 1769, pp. 60-68 : 65-67

Tautoneura longiprocessa sp. nov.

( Figs. 11–20 , 25, 26 )

Morphology: Structural characters as in T. multimaculata , but anteclypeus slim, not broad. Vertex and pronotum ( Fig. 11 ) brownish-yellow with testaceous-brownish patches. Eyes brownish black. Scutellum ( Fig. 11 ) milky yellow, basal triangles brownish-yellow. Thorax dirty yellow; abdomen vivid-yellowish, turning brown yellow caudally. Forewing ( Fig. 19 ) yellow, brownish at apex, with 3 red markings around claval suture and 3 round black spots; hindwing ( Fig. 20 ) transparent, veins obvious, two transverse veins closely aligned to each other.

Male genitalia: Abdominal apodemes ( Fig. 18 ) long and broad, reaching 5th segment. Pygofer lobe ( Fig. 12 ) broad, with 3 macrosetae and a few microsetae at basal lower angle of lobe and numerous microsetae distributed in caudal part. Dorsal appendage tapering sharp (“sharp” means a blade) apically. Ventral appendage slightly curved ( Fig. 12 ). Subgenital plate ( Fig. 13 ) with 3 macrosetae near median area; expanded at base and with a few peg-like setae. Aedeagus ( Figs. 14, 15 ) with a pair of very long belt-like apical processes, and two small teeth-like processes at middle of shaft; gonopore ( Fig. 14 ) apical. Anal tube appendage extremely long, hook-like at apex.

Measurement: Body length males 2.9–3.0 mm, females 3.0–3.1 mm.

Material examined: Holotype, male: CHINA, Guizhou: Lianhuaping, Mt. Leigong, 26°43'N 108°20'E, 1400–2170 m., 15–IX–2005, coll. Yuehua Song. Paratypes: one male, six females, same data as holotype.

Remarks: This new species is similar to T. formosa ( Dworakowska, 1970) , which also has the aedeagal shaft with two pairs of processes, but can be distinguished from the latter by the following characteristics: 1) forewing of T. formosa with one large, carmine-red patch on clavus and some blackish-brown spots on corium, but the new species with 3 red markings around claval suture and 3 round black spots ( Fig. 19 ); 2) the new species with a pair of long ribbon-like apical processes ( Fig. 14 ) and pair of small tooth-like processes at middle of shaft ( Figs. 14, 15 ), a feature unique within the genus; the apical processes of T. formosa shorter, with sculpture at apex and the second pair of processes finger-like, not teeth-like ( Figs. 25, 26 ); 3) style of T. formosa with very long, twisted upper extension apically, and that of the new species short and expanded at apex.

Etymology: The specific name refers to long processes of the aedeagus shaft.
