Kolla emphysematosa Feng & Zhang sp. nov.

( Figs. 1 A–D, 2A–H)

Description. Crown with small round black spot corresponding to each ocellus, coronal suture black, pair of transverse black submedial maculae on anterior margin and small black spot at apex of head; face yellow with distinct clypeal muscle impressions and longitudinal brownish spot on anteclypeus; pronotum with black anterior transverse band interrupted by median oval pale spot, pair of small black sublateral maculae at midlenght, midline and broad posterior transverse band black; scutellum orange with basolateral triangles black; forewing black except for narrow transparent yellow stripe along costal margin and narrowly yellow commissural margin of clavus.

Male pygofer with macrosetae located posterodorsally and dense microsetae near middle of disk; ventral process with group of stubby microsetae at base, abruptly narrowed near midlength, then becoming slender with acute apex in lateral view, curved posteromesad; plates concave near midlength of outer margin, inner margin almost straight, with uniseriate macrosetae and scattered microsetae. Aedeagus bent dorsad in lateral view, lobes of shaft broadly rounded with acute dorsal projection, aedeagal shaft wide basally in lateral view, without protuberance between two lobes in caudoventral view.

Measurement. Length of male 5.5–5.7mm

Material examined. Holotype: ♂, China, Sichuan Province, Batang, 11 July 2001, coll. Sun Qiang; Paratype: 1 ♂, same data as holotype but with light trap.

Remarks. This species is similar to K. lunulata Li & Wang, 1991 , but can be easily distinguished from the latter by the following differences: anteclypeus with longitudinal brownish spot ( Fig. 1 D), pronotum with pair of small black sublateral maculae at midlength ( Fig. 1 C), pygofer posterior margin smoothly convex ( Fig. 2 A), and processes abruptly narrowed near midlength ( Fig. 2 D), connective‘Y’- shaped with inflated manubrium near midlength ( Fig. 2 E), and apex of aedeagus not significantly hooked ( Figs 2 G, 2H).

Etymology. This new specific epithet is derived from Latin word “emphysematosus” referring to the wide base of the aedeagal shaft.
