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

6. Salka longipenia Lin & Zhang sp. nov.

( Figs 1u–x , 8 )

Description. External features as in S. dipteriga ( Figs 1u, v, w, x ).

Male 2S abdominal apodemes extending to posterior part of sternite III ( Fig. 8b ). Anal tube without appendage ( Fig. 8a ).

Pygofer with posterior margin rounded and cephalo-ventral part intumescent; dorsal appendage tapered towards apex and hook-like in lateral view, apex surpassing posterior margin of pygofer lobe; ventral appendage immovably fused to pygofer lobe, tapered towards apex, apex extending to hind margin of pygofer lobe ( Figs 8a, c ). Several microsetae and microtrichia scattered on distal part of pygofer lobe, meanwhile, a group of medium sized setae at cephalo-ventral angle ( Fig. 8a ). Subgenital plate equal sided in lateral view and curved dorsad near middle, with 3 macrosetae of different sizes in a row subbasally and row of microsetae along outer margin from subbase to apex, subbasal microsetae larger and forming a group ( Fig. 8a ). Connective with manubrium quite broad, central lobe slightly longer than lateral arms ( Fig. 8d ). Style apex footlike with acute heel and much longer toe, with minute furrows and row of irregular teeth ( Figs 8e, f ). Aedeagus with dorsal apodeme well developed, triangular; preatrium short and slender; shaft tubular and extremely long with apex distinctly exceeding posterior margin of pygofer lobe, several tiny tubercles on ventral surface subapically, gonopore subapically on ventral surface ( Figs 8g, h ).

Measurement. Male 2.80mm, female 2.70mm.

Material examined. Holotype: ♁, CHINA, Guangxi Prov., Laibin , 2018.VII.13, coll. Shuanghu Lin ; Paratypes: 2♁ 1♀, same data as holotype; 1♁, CHINA, Guangxi Prov., Baise , 2018.VII.3, coll. Shuanghu Lin.

Remarks. This new species is similar to S. diaoluoensis , but has the aedeagal shaft extremely long with apex distinctly surpassing the posterior margin of pygofer lobe and without large processes.

Etymology. This specific epithet is derived from the Latin “longus” and “penis”, referring to the aedeagal shaft being extremely long.
