Calichodes Warren stat. rev.
Type species: foveata Warren (by monotypy) = subrugata Walker.
The genus-group name Calichodes was first published by Warren
(1897, Novit. zool. 4: 246), though was not flagged as a new genus in the
author's usual fashion. The name (with reference to "Warren M.S”. ) was
proposed as a new subgenus of Boarmia, with a different type species, by
Wehrli (1943, in Seitz, Gross-Schmett. Erde 4, Suppl., p. 544). Fletcher
(1979) referred only to the usage by Wehrli, followed by Sato (1993). However,
the earlier usage is valid under the International Code of Zoological
Nomenclature and therefore has priority (I.W.B. Nye, pers. comm.).
The single species included is small with whitish ground colour marked
with dark brownish grey. The postmedials are characteristically bidentate. The
male antennae are bipectinate to about three quarters, those of the female being
filiform. The male forewing has a strong fovea.
In the male abdomen the eighth segment is elongate. There is no setal
comb on sternite 3. In the genitalia the uncus is small, the gnathus absent. The
valves are narrow, with a fine, sinous costal thickening that has a zone of
setae just short of the apex of the valve. Basal to this setal zone is an
irregular flange that traverses the valve lamina and bears two setal spines
directed basad.
The female genitalia have the ductus very short, sclerotised. The bursa
has the basal part slender, continuing from the ductus, corrugate and finely
scobinate. The distal bulb is more or less spherical and contains a massive
signum with a broad, square base with the rim bearing a pair of strong,
irregular spines at each corner.
