( FIGS 49 View Figures 27–54 , 102 View Figures 91–102 , 150 View Figures 132–155 , 172 View Figures 156–175 , 205 View Figures 200–210 )

Description: Antenna in male bipectinate, outer rami longer than inner rami, apical one-third without rami, the longest ramus about six to seven times diameter of antennal shaft. Frons slightly protruding, green, lower margin white. Vertex green. Tegula with green base and white end. Dorsal sides of thorax and abdomen green (yellowish-brown after discoloration), third and fourth segments of abdomen reddish-brown. Hind tibia in male with two pairs of spurs, terminal extension slightly shorter than the first tarsus.

Forewing length: ♂ 12 mm. Outer margin of both wings smooth, that of forewing almost straight; apex of hindwing protruded. Wings green tinged with blue. Forewing with costal area white, brown at base; antemedial line linear, straight and oblique outwards; postmedial line composed of small indistinct white dots on veins. Both wings with small, blackish-brown discal spots; terminal line brown; fringes pale green. Underside: forewing with costal base brown; both wings with discal spots same as that of upperside; no other streaks present.

Third sternite in male with a pair of setal patches. Eighth abdominal segment modified, with posterior margin of tergite sclerotized and protruding at middle; sternite concave at middle.

Male genitalia. Uncus short, with terminal onethird bifid. Socii developed, very long, about twice length of uncus, tapering. Gnathos reduced. Valva oblong, apex truncate, with a small blunt process on costal end; costa slightly swollen at middle; ventral region of valva setose. Vinculum deeply bifurcate, with two branches quite long and tapering. Juxta an indistinct rounded sclerite. Aedeagus long and thin, with posterior end expanded, oval, and spinose.

Female genitalia. Sterigma unmodified. Ductus bursae very broad and long, slightly tapering towards corpus bursae, the latter quite small. Signum absent.

Diagnosis: Chlorochromodes rhodocraspeda   is close to Ch. chlorochromodes   and Ch. tenera   in the wing pattern. In the male genitalia, Ch. rhodocraspeda   has a short bifid uncus, which is identical to that of Ch. tenera   , but the uncus   is reduced in Ch. chlorochromodes   ; the tapering lobes of the vinculum are similar to those in Ch. tenera   but differ from those of Ch. chlorochromodes   , which are of even width; the valva bears only one small blunt process on the tip of the costa whereas there are two in Ch. chlorochromodes   and Ch. tenera   . Chlorochromodes rhodocraspeda   is also distinctive in the aedeagus, which is expanded and spinose posteriorly, but only spinose in the other two species.

Holotype ♂, China: Siao-Loû, Chasseurs Indigènes du P. Déjean, 1903 (other label: red label: Hemist. rhodocraspeda Wrli.   , Type; Comibaena rhodocraspeda Wrli. Typ.   ) (ZFMK). Paratypes: China: 1♀, Tibet: Mêdog, Hanmi, 2095 m, 10–11.iii.2006, coll. Lang Songyun, IZCAS slide no. Geom-01152 (IZCAS).

Distribution: China (Sichuan, Tibet).

Etymology: rhodocraspeda   is derived from two Greek words meaning ‘rosy’ and ‘border’.

Remarks: This species was named as rhodocraspeda   by Wehrli (both in ‘ Hemist.’ (short form of Hemistola   ) and Comibaena   ), and labelled accordingly on the specimen, but the name was never published, and is therefore invalid under the Code of the International Commission on Zoological Nomenclature. We have therefore decided to preserve the name by publishing it as a new species. Dissection of the genitalia has demonstrated that it belongs to the genus Chlorochromodes   .
