Lin, Shuanghu, Zou, Hongfen, Huang, Min & Zhang, Yalin, 2023, Taxonomic study of the leafhopper genus Salka Dworakowska (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini) from China, with descriptions of seven new species, Zootaxa 5228 (4), pp. 394-410 : 402-410

7. Salka taopenna Lin & Zhang sp. nov.

( Figs 2a–d , 9 )

Description. Crown yellowish with median spot not extended to base, coronal suture only distinct basally. Eyes gray and blackish. Face slightly flat in profile. Other features as in generic description ( Figs 2a, b, c, d ).

Male 2S abdominal apodemes extending to posterior part of sternite III ( Fig. 9b ). Anal tube with well sclerotized dorsal ring on distal region ( Fig. 9a ).

Pygofer dorsal appendage curved ventroposterad, apex slightly expanded with numerous spiculate processes; ventral appendage absent ( Figs 9a, c ). Pygofer side with 2 macrosetae near base of dorsal appendage and several stout microsetae at cephalo-ventral angle, with numerous circular pits on inner side of distal part ( Fig. 9a ). Subgenital plate slightly constricted medially, with row of microsetae along outer margin from subbase to apex and 4 macrosetae of different sizes in a row from subbase to middle ( Fig. 9a ). Connective resembling that of S. aequilonga , but manubrium much narrower, median lobe slender and slightly longer than lateral arms ( Fig. 9d ). Style resembling that of S. delphiura ( Figs 9e, f ). Aedeagus with dorsal apodeme and preatrium well developed, as long as shaft; shaft with angulate dorsal preapical projection in lateral view, gonopore apical ( Figs 9g, h ).

Measurement. Male 3.10–3.20mm, female 3.15–3.25mm.

Material examined. Holotype: ♁, CHINA, Hunan Prov., Chenzhou, 2020.VII, coll. Deliang Xu ; Paratypes: 8♁ 4♀, same data as holotype .

Remarks. This new species is similar to S. delphiura , but has the aedeagal shaft without paired distal processes and the pygofer dorsal appendage with spiculate processes apically.

Etymology. This specific epithet is derived from the Greek “tao” (peacock) and the Latin “penna” (feather), referring to the pygofer dorsal appendage with spiculate processes apically, resembling a peacock feather.
