Salka acicula, Song, Yue-Hua & Li, Zi-Zhong, 2016

Song, Yue-Hua & Li, Zi-Zhong, 2016, New additions to the leafhopper genus Salka Dworakowska (Hemiptera: Cicadellidae: Typhlocybinae) from Hainan and Henan Provinces of China, Zootaxa 4092 (3), pp. 445-450 : 447-448

Salka acicula sp. nov. ( Figs 1–7 )

Description. Vertex brownish yellow, with large irregular central black spot ( Fig. 1 ). Eyes black ( Fig. 1 ). Pronotum blackish brown, with anterior margin and intermediate zone light yellow ( Fig. 1 ). Scutellum dark, with basal triangles indistinct ( Fig. 1 ). Face light yellow, without obvious patches. Fore wing brownish yellow, with brochosome field dark brown.

Male abdominal apodemes slightly exceeding 3rd sternite ( Fig. 2 ).

Male genitalia: Pygofer dorsal appendage not extended beyond caudal margin of lobe, little curved ventrally, with apex sharp ( Fig. 3 ). Pygofer ventral appendage long and slim, branched about 1/3 distance from apex, dorsal branch long, ventral branch extremely short ( Fig. 3 ). Subgenital plate with 3 macrosetae on outer surface and row of short setae along upper margin, basal setae of row longer than distal setae ( Fig. 3 ). Style tapering towards apex ( Fig. 4 ). Aedeagus wide in lateral view, with pair of small lateral processes arising near midlength of shaft; gonopore apical on ventral surface ( Figs 5, 6 ). Connective Y-shaped, with distinct central lobe ( Fig. 7 ).

Specimen examined. Holotype: ♂, CHINA, Hainan Prov., Jianfengling, 800~ 900m, 12-VII-2007, coll. Qiongzhang Song. Paratype: 2♂♂, 2♀♀, same data as holotype.

Measurement. Body length males 2.9–3.0 mm, females 3.1–3.3 (including wing).

Remarks. This species is similar to Salka fujiwara Chiang & Knight (1990) , but differs in having the aedeagus with a pair of small processes arising from the middle of the aedeagal shaft laterally ( Figs 5, 6 ); the pygofer ventral appendage bifurcate 1/3 distance from the apex ( Fig. 3 ); and the apex of the style long and tapered ( Fig. 4 ).

Etymology. The specific name is derived from the Latin word “ aciculus ”, referring to the aedeagus with one paired small appendage ( Figs 5, 6 ).
