Fore wing light white, patches stripped in Fig. 3, ochre-yellow or orange yellow; smoked apical pattern brownish; both ends of brochosome field orange brown.

Abdominal apodemes ( Fig. 4) long, extended beyond posterior margin of 4th sternite.

Subgenital plate ( Fig. 6) short, with row of macrosetae along upper margin, without marginal subbasal setae or setae poorly developed. Style ( Fig. 7) slender, preapical lobe prominent, cheliform. Aedeagal shaft ( Fig. 9) long, upper part thin, tubular, slightly curved dorsally, with a large apical process; another appendage arising from subapex of aedeagal shaft long and strong, expanded at base and tapering towards apex. Aedeagus ( Figs. 8, 9) with preatrium much shorter than shaft, dorsal apodeme broadened in lateral view, nearly triangular.

Specimen examined. Holotype, ♂, China, Hainan Province, Datian , 100 m, light trap, 9-VII-2007, coll. Yuehua Song. Paratypes: 1♂, 1♀, China, Hainan Province, Jianfeng Town , 800 m, light trap, 12-VII-2007, coll. Yuehua Song.

Measurement. Body length males 2.6~2.7 mm; female 2.7 mm.

Remarks. The new species is similar to K. maculata Dworakowska, 1981 , but can be distinguished from the latter by the following characters:

(1) the new species with a large appendage arising from subapex or near median of aedeagal shaft ( Fig. 9) and that of K. maculata arising from base of aedeagal shaft;

(2) the new species with preatrium ( Fig. 9) short and broad, but the latter preatrium absent;

(3) aedeagal shaft of K. maculata , whole tubular, the aedeagal shaft ( Fig. 9) of new species just with upper part tubular, but its lower part expanded distinctly.

Etymology. The new species is named after its locality.
