Calodesma dioptis (Felder & Rogenhofer, 1874)

Felder, C., Felder, R. & Rogenhofer, A. F. (1874). Reise der österreichischen
Fregatte Novara um die Erde in den Jahren 1857, 1858, 1859. Zoologischer Theil,
Bd. 2, Abth. 2: Lepidoptera, Heft 4: pl. 103, fig. 13. Described in the genus
Chamesthema. The original consists of the figure only, with no text; the
explanation of the plates (Rogenhofer, 1875, Heft 5, "Inhalt der Heterocera-
Tafeln") gives only the legend:

Chamesthema (subg. Esthemae) Dioptis F. ♂, fl. Amazonas (Bates).

Hering, M. (1925). Calodesma. In: Seitz, A. (ed.), The Macrolepidoptera of the
World, vol. 6, The American Bombyces and Sphinges: p. 433, pl. 60 g (German
edition: Die Gross-Schmetterlinge der Erde 6: 433).

C. dioptis Fldr. (60 g). For this species Felder established the genus
Chamesthema. ♂ similar to those of the preceding species, abdomen above with a
white longitudinal line and below with broad whitish curls; head and patagia
partly white. Forewing with a white longitudinal area behind the cell and a
wedgeshaped longitudinal stripe in the cell. Hindwing with a white, black-veined
central area, which may be very much darkened. Discernible from the ♂♂ of C.
collaris Drury (60 h), in which also the forewing may be brightened up behind
the cell, by the white dorsal abdominal line. From Venezuela to Brazil and
Bolivia.

"The preceding species" are C. albiapex, C. plorata and C. collaris, each
described by comparison with the one before it, back to C. contracta; the
paragraphs (pp. 432-433):

C. contracta Wkr. (60 h). Body black, head below, collar and ground of patagia
as well as prothorax below ochreous-yellow. Wings as in amica, but the markings
intensely yellow, sometimes warming into reddish. The bands are very variable in
the different examples, those of the hindwing often only traceable or entirely
absent. From Venezuela to South Brazil and Peru. The typical contracta has uni-
coloured fringes of the ground-colour of the wings. -- itaitubae subsp. nov.
from Itaituba has lighter fringes, those of the apex of the forewing beneath are
white. -- apicalis subsp. n., from Bahia, is similar to the preceding, the apex
of the hindwing above with a yellow, beneath with a white spot.

C. collaris Drury (60 h) is like contracta, but the markings are white, in the
hindwing sometimes dingy white, often indistinct or absent. In the ♂ the yellow
colouring at the prothorax more extensive. Apex of abdomen likewise ochreous-
yellow. Band of forewing shortened, only a white spot behind the cell, hindwing
uni-coloured. Fringes in the ♂ white, in the ♀ black. Range as in contracta.

C. plorata Kaye is unknown to me; it is said to have only the bases of the eyes
and of the palpi ochreous-yellow, otherwise like the preceding. Trinidad.

C. albiapex sp. n. (60 h) resembles plorata, fringes in the ♀ white, ♂ and ♀ at
the apex of the hindwing with a narrow white spot. Band of forewing oftener than
in plorata shortened also in the ♀. Type (♂ and ♀) in the Berlin Museum from
Pernambuco; Bahia. ♀ from Paraguay in the Tring Museum.
