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 : 401-402

5. Salka aequilonga Lin & Zhang sp. nov.

( Figs 1q–t , 7 )

Description. Crown gray with a large blurred brown patch, coronal suture developed, exceeding mid-length. Eyes gray. Face slightly flat in profile. Other features as in generic description ( Figs 1q, r, s, t ).

Male 2S abdominal apodemes extending to posterior margin of sternite III ( Fig. 7b ). Anal tube with well sclerotized dorsal ring on distal region ( Fig. 7a ).

Pygofer dorsal appendage bifurcated medially, lower branch much shorter than upper branch, ventral appendage long, slender and bent posterad beyond midlength, with apex distinctly surpassing posterior margin of pygofer lobe ( Figs 7a, c, d ); 2 macrosetae and several microsetae around dorsal appendage scattered on pygofer side, with group of relatively long, stout setae at cephalo-ventral angle ( Fig. 7a ). Subgenital plate resembling that of S. limboserrata to a large extent in lateral view, but with 4 macrosetae subbasally not in a row ( Fig. 7a ). Connective with manubrium relatively broad, median lobe slender and slightly longer than lateral arms ( Fig. 7e ). Style with apex slim, small and foot-like with angulate heel and slightly longer toe ( Figs 7f, g ). Aedeagus U-shaped with dorsal apodeme almost same length and width as shaft in lateral view, shaft tubular and curved dorsad subapically, without process, gonopore in middle on ventral surface ( Figs 7h, i ).

Measurement. Male 2.45–2.50mm, female 2.45–2.50mm.

Material examined. Holotype: ♁, CHINA, Zhejiang Prov., Lishui , 2017.Ⅴ.20, coll. Shuanghu Lin ; Paratypes: 5♁ 9♀, same data as holotype .

Remarks. This new species is similar to S. fanjinga , but has the apex of the subgenital plate rounded in lateral view, the style apex short, and the aedeagal shaft without apical process.

Etymology. This specific epithet is derived from the Latin “aequilongus” (same length), referring to the aedeagus with dorsal apodeme almost same length as shaft in lateral view.
