Feng, Ling & Zhang, Yalin, 2015, Leafhopper genus Kolla Distant (Hemiptera: Cicadellidae: Cicadellinae) with descriptions of four new species from China, Zootaxa 3999 (3), pp. 430-438 : 436-437

Kolla petalina Feng & Zhang sp. nov.

( Figs. 1 M–P, 5A–H)

Description. Crown with large irregularly round medial black spot between ocelli and extended to posterior margin; anterior margin with pair of large submedial maculae and small median spot; face orange, with black medial spot near ventral margin postclypeus; posterior half of pronotum black with median acute lobe extended into anterior half; scutellum black basally, orange apically, midline orange; forewing black except narrow transparent yellow stripe along costal margin.

Male pygofer with macrosetae posterodorsally and scattered microsetae near middle of disk; ventral process wide at base with group of microsetae, slightly sinuate distally, apex extended posterodorsad slightly beyond pygofer apex; plates each with inner margin concave near midlength, outer margin gently concave, with two lines of macrosetae in base, then with one line and sparse microsetae. Aedeagus bent dorsad in lateral view, shaft with pair of petal shaped lobes, with short protuberance between two lobes in caudoventral view.

Measurement. Length of male 5.8–6.0mm.

Material examined Holotype: ♂, China, Zhejiang Province, Fengyangshan Nature Reserve, 6 August 2008, coll. Gao Xia; Paratypes: 1 ♂, China, Fujian Province, Wuyi Mountain, 4 August 2009, coll. Cao Yanghui; 1 ♂, China, Fujian Province, Wuyi Mountain, 6 August 2009, coll. Cao Yanghui.

Remarks. This species is similar to K. paulula (Walker, 1858) , but it can be easily distinguished from the latter by the following differences: scutellum black basally, orange apically, midline orange ( Figs 1 M, 1O), aedeagal shaft with a pair of distinct petal-shaped lobes, and a short protuberance between the two lobes ( Figs 5 G, 5H).

Etymology. The new specific epithet is derived from the Latin word “petalinus”, indicating the aedeagal shaft with a pair of petal shaped lobes.
