Diagnosis. In facies, C. chitonregis is nearly indistinguishable from C. durranti, but in C. chitonregis the brown basal line of the hindwing continues to the apical part of wing, the sterigma has a short anteostial part, and the signum is broader, situated in the posterior end of the ductus bursae.

Forewing 9.0 mm (n = 3); ground colour of forewing orange; grey reticulation sparse; refractive lines well developed; black blotch at midcosta rather small. Fringe brownish black. Hindwing orange; apical marking consisting of subapical line and trace of marginal line. Fringe orange cream, mixed blackish in apical area; basal line to end of vein M3. Abdomen: Male genitalia not examined. Female genitalia (Fig. 8) with papilla analis broad with short proximal part; sterigma rounded proximally; ductus bursae fairly broad, short, with broad, anteriorly elongate, minutely spined, shieldshaped sigmum in posterior portion.

Etymology. The name refers to the beautiful colouration of this moth, from the Greek “chiton,” meaning robe, and the Latin “regis” meaning royal or king.
