Comostolodes Warren
Gen. rev.
Type
species: albicatena Warren.
Synonyms:
Chlorochromodes Warren (type species tenera Warren, N.E. Himalaya)
syn. n.; Hercoloxia Prout (type species chlorochromodes Prout,
Java) syn. n.
In
facies this genus resembles the next in being marked by marginal and, on the
forewing, oblique antemedial and postmedial arrays of white spots that are
usually ringed with red. The species are small. The type species of the generic
synonyms lack the typical markings but have the definitive genitalic features
noted below: they could be treated as subgenus Chlorochromodes, the taxa tenera
Warren and chlorochromodes Prout having almost identical male
genitalia.
In
the male abdomen the eighth segment is modified in a manner similar to that of
the Nemoriiti (Geometrini). In the genitalia the uncus is vestigial, the socii
prominent. The genus is defined by the saccus where the angles of the rather
squared Comibaeniti state are produced into slender processes that lie very
close together, giving a bifid effect, the best diagnostic feature for the
genus. In the typical subgenus the valve has a large hook arising from the costa.
In Chlorochromodes this is lacking, and the valve is apically excavate.
In
the female (C. dialitha West) the bursa is reduced, the ductus large,
irregularly thickened distally, basally sclerotised down to the funnel-like
ostium.
The
genus is restricted to the Oriental tropics. It should also include C.
subhyalina Warren comb.n. (Himalaya).
