Draudt, M. (1915). Cosmosoma. In: Seitz, A. (ed.), The Macrolepidoptera
of the World, vol. 6, The American Bombyces and Sphinges: p. 75, pl. 13 g
(as C. carabayanum; transferred to Gymnelia in the Additions and
Corrections, p. 198).

C. carabayanum Rothsch. (13 g) greatly resembles the preceding species,
from which it differs by the more golden yellow, black-margined collar
and shoulder-covers, and by the quite golden yellow palpi and legs; the
black abdomen exhibits above on the 4 first segments, laterally also on
the fifth, golden yellow bands; the 4th and 5th segments show metallic
greenish-blue dorsal spots, the last 3 rings broad metallic bluish-green
bands. The wings are not so yellowish as in the preceding species; the
base of the proximal margin in the hindwing yellow. Peru.

"The preceding species" is bricenoi, which Draudt describes thus (p. 75):

C. bricenoi Rothsch. (13 g) looks like a Gymnelia. Head orange with a
black spot on the forehead; collar and thorax orange and black; the
abdomen is black, on the first 4 segments subdorso-laterally with deep
orange bands; above with metallic blue spots, on the 3 last segments also
laterally. Palpi, antennae and legs black, forehips orange. On the wings
only the apex of the forewing, the proximal margin and fringes are black,
the costal margin and a basal inner-marginal spot yellow. Venezuela
