Adults

1. Forewing membrane with reduced and obscure pale brown spots at the location of the radular spinules in cells m, m, and 1 2 cu 1 (Fig. 13); antenna often longer than 2.4 times head width; anterior margin of paramere broadly rounded; female proctiger slender, very weakly curved at dorsal margin, almost appearing straight, and not upturned apically (Fig. 16)............................................................................................... C. burckhardti sp. nov.

- Forewing membrane with three or four prominent dark brown spots at the location of the radular spinules (Figs 3, 22); antenna shorter than 2.4 times head width; anterior margin of paramere angularly projected; female proctiger rather stout, strongly or weakly curved, and slightly sinuate at dorsal margin, slightly upturned apically (Figs 6, 25).......................... 2

2. Forewing membrane with three prominent dark brown spots at the location of the radular spinules in cells m 1, m 2, and cu 1 (Fig. 3); paramere more constricted in the middle, anterior margin projection located near the top of paramere and close to the sclerotized tooth (Figs 4–5); female proctiger slightly truncated at the apex (Figs 6, 32).................. C. hexastigma

- Forewing membrane with four prominent dark brown spots at the location of the radular spinules in cells r 2, m 1, m 2, and cu 1 (Fig. 22); paramere less constricted in the middle, anterior margin projection located around the apical 1/4 of paramere and apart from the sclerotized tooth (Figs 23–24); female proctiger round at the apex (Figs 25, 34)................. C. willieti

Fifth instar immatures

1. Shorter setae on the forewing pad margin capitate (Fig. 31)............................................. C. willieti

- Shorter setae on the forewing pad margin simple hair-like (Figs 29–30).......................................... 2

2. Body setae generally longer, e.g. capitate seta on the middle of antennal segment III longer than the thickness of antennal segment III (Fig. 26)....................................................................... C. hexastigma

- Body setae generally shorter, e.g. capitate seta on the middle of antennal segment III as long as or shorter than the thickness of antennal segment III (Fig. 27)......................................................... C. burckhardti sp. nov.
