Kolla prolongata Feng & Zhang sp. nov.

( Figs. 1 E–H, 3A–H)

Description. Crown with diffuse black cruciform marking between ocelli, pair of transverse black submedial maculae and small median black spot on anterior margin; face yellow without obvious clypeal muscle impressions; posterior half of pronotum black with black rounded lobe extended into anterior half medially; scutellum orange with basal triangles and median posterior macula black; forewing black except narrow transparent yellow stripe along costal margin.

Male pygofer with macrosetae posteriorly and evenly distributed microsetae; ventral process with fine setae at base, nearly straight and evenly tapered for most of length, abruptly curved dorsad before apex of pygofer; plates each with inner margin obviously concave near midlength, outer margin almost oblique, with several microsetae in base, with uniseriate macrosetae along the side of its outer margin; aedeagus bent dorsad in lateral view, shaft with lobes relatively narrow, widely divergent, without dorsal projection; base of aedeagal shaft elongated in lateral view, without protuberance between two lobes in caudoventral view.

Measurement. Length of male 6.1–6.2 mm.

Material examined Holotype: ♂, China, Zhejiang Province, Qingliangfeng Nature Reserve, 11 August 2011, coll. Wang Yang; Paratypes: 1 ♂, China, Hainan Province, Jianfengling, 20 July 2009, coll. Gao Xia; 1 ♂, China, Guangxi Province, Guilin, 28 August 1974, coll. Chou Io; 1 ♂, China, Zhejiang Province, Qingliangfeng Nature Reserve, 6 August 2008, coll. Gao Xia.

Remarks. The new species is very similar to K. paulula (Walker, 1858) , but can be easily distinguished from the latter by the following differences: crown with diffuse black cruciform marking between ocelli ( Fig. 1 ), scutellum with basal triangles and median posterior macula black ( Figs 1 E, 1G), plates each with inner margin obviously concave near midlength ( Fig 3 B), base of aedeagal shaft elongated ( Fig. 3 H). It is also similar to K. rhabdoma Yang & Li, 2000 but differs from the latter by the markings on the crown and thorax in dorsal view and on the face; and the shape of its aedeagus and subgenital plate.

Etymology. This new specific epithet is derived from Latin word “prolongatus”, referring to the base of the aedeagal shaft being elongated.
