Neochloroglyphica perbella Han & Skou , sp. nov.

Description. Head. Frons bluish green (light brown after discoloration). Labial palpus pale green, the third segment very short, not elongate in female. Vertex with anterior half white, posterior half bluish green.

Thorax. Dorsal side of thorax concolorous with wings, deep bluish green, ventral side whitish.

Wings. Forewing length: male 18.5–20 mm; female 18.5 mm. Wings deep bluish green, diffused with white striations. Forewing with costa a narrow straw-yellow band, decorated with black spots. Antemedial line white, slender, sinuous, from basal quarter of costa to basal one third of inner margin; postmedial line white, almost straight, slightly bending inwards near costa; submarginal line indistinct, sinuous, whitish. Hind wing with postmedial line straight, slightly tapering towards anal margin; submarginal line white, wavy, more distinct than on forewing. Discal spot deep green on discocellulars. Fringes of both wings with basal half dark brown, terminal half whitish, dark brown on M 3 end of hind wing. Underside of wings much paler than upperside, with forewing basal half and hind wing more whitish, streaks on upperside discernible.

Abdomen. Dorsal side of abdomen deep bluish green, yellow after discoloration, with a row of white dots at middle. Third sternite of male abdomen with a pair of setal patches. Male eighth segment modified, a broad tergite bearing two short, pointed and curved lateral processes, a narrow sternite deeply concave at middle, V-shaped ( Fig. 15 ).

Male genitalia ( Figs 7 , 12 ) and female genitalia ( Fig. 18 ) are as in description of the genus.

Etymology. The specific name is derived from the Latin word “ perbellus ”, which means very beautiful.

Note. In the collection of IZCAS, there are four female specimens collected from the same locality, and unilateral legs of two specimens were taken off and preserved in anhydrous ethanol, numbered as IOZ LEP M 14495, 14496. Sequences were successfully obtained from the two specimens. Only specimen 14495 ( Fig. 5 ) was spread while specimen 14496 remained papered. At present we are unfortunately unable to locate the latter, and therefore do not include it in the type series, though we are certain that it is in somewhere in the Lepidoptera collection of IZCAS .

Diagnosis. As in the diagnosis of the genus.

Distribution. China (Yunnan).
