Generic characters.

Head. Antennae lamellate, partly unipectinate, rami very short (Fig. 1a). Frons not protruding. Labial palpi with third segment distinct, up-curved. Thorax. Hind tibia with two pairs of spurs. Apex of forewing often rounded, sometimes pointed and protruding. Wing colour usually white or grey (except Cyclidia orciferaria ); antemedial and postmedial lines of forewing double; medial line of forewing broad; terminal lines of both wings usually double, sometimes single (e.g. Cyclidia substigmaria , Cyclidia rectificata , and Cyclidia diehli Lutz & Kobes, 2002). Venation (Fig. 3a). Forewing with R1 separate, R2-4 and R5 stalked, R2 and R3+4 stalked, R5 and M1 separate, M2 arising from middle of discocellulars; Hind wing with Sc+R1 close to Rs beyond distal cell, then far from Rs, M2 arising from middle of discocellulars. Anterotergal syndeses developed at anterior margin of 2nd tergum (Fig. 2). A pair of androconial hair-pencils present on 2nd sternum of male (Fig. 2). Male genitalia. Uncus triangular; socii developed, often sclerotized (except Cyclidia orciferaria ), sometimes with small setose process at base (e.g. Cyclidia pitimani (Moore, 1886), Cyclidia sericea and Cyclidia diehli ); gnathos connected at middle and with median process narrow and triangular; valva simple and broad; juxta deeply concaved posteriorly; saccus short and broad, rounded terminally; phallus slightly curved; vesica without cornuti. Female genitalia. Papillae anales broad and rounded; lamella postvaginalis usually well developed; ductus bursae very long and narrow, with a colliculum; corpus bursae oval, with a paired band-like spinose signa.

Diagnosis.

Cyclidia is quite different from Mimozethes externally and in the genitalia. For example, externally, the rami of the antennae are much shorter; the species of Cyclidia are much larger, and the postmedial lines of forewing are often double, while in Mimozethes , it is single and forms a “>” shaped protrusion near R5; in the male genitalia, the socii are well developed in Cyclidia , but absent in Mimozethes ; the sacculus unmodified in Cyclidia but forming a process in Mimozethes ; in the female genitalia, the signa are a paired band-like sclerotization in Cyclidia , but absent in Mimozethes .

Distribution.

China, Japan, Korean Peninsula, south and southeast Asia.
