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 : 435-436

Kolla procerula Feng & Zhang sp. nov.

( Figs. 1 I–L, 4A–H)

Description. Crown with large median semicircular black spot touching basal margin, apical margin with pair of large black submedial maculae and small median black spot; face dark yellow with distinct clypeal muscle impressions; pronotum and scutellum black except small apical area of scutellum yellow; forewing black except for narrow transparent yellow stripe along costal margin.

Male pygofer with a group of macrosetae located posterodorsally and evenly distributed microsetae on disk; ventral process with fine microsetae distributed evenly on basal half, distal half slender, twisted, extending slightly beyond pygofer apex; plates each with inner margin slightly concave near midlength, outer margin oblique, with uniseriate macrosetae and densely covered by long fine setae; aedeagus evenly curved dorsad in lateral view, shaft with lobes small and acute in lateral view, with short protuberance between them in caudoventral view.

Measurement. Length of male 5.4–5.6 mm.

Material examined. Holotype: ♂, China, Hebei Province, Weixian, 20 June 2009, coll. Qin Daozheng; Paratypes: 1 ♂, China, Ningxia Hui Autonomous Region, Liupanshan Mountain, 22 June 2008, coll. Meng Qiulei; 1 ♂, China, Gansu Province, Xinglong Mountain Nature Reserve, 27 July 2012, coll. Xue Qingquan.

Remarks. This species is similar to K. atramentaria ( Motschulsky, 1859) , but can be easily distinguished from the latter by the different color pattern, less strongly produced head ( Figs 1 I-1L), male plates densely covered by long fine setae ( Figs 4 A, 4B), and aedeagal shaft with lobes small and acute with a short protuberance between them ( Fig. 4 G).

Etymology. This new specific epithet is derived from the Latin word “procerulus”, referring to the short protuberance between two aedeagal shaft lobes.
