species: viola Hampson,
(type species viola), praeocc.
this genus has extremely long, forward-directed labial palps, about three times
the length of the head, though a similar feature is also seen in Parilyrgis
longirostris Hampson (Bali, Singapore). The type species is known only from
the holotype female, which is much larger than the Bornean species or E. butleri Leech (Japan, Taiwan). The forewings are
more elongate than in Ilyrgis with
similar, if fainter, fasciation to the wings and angling to the hindwing margin.
The forewing costa is diagnostically sinuous, being distinctly bowed at one
third (this feature is weak in butleri).
abdomen (butleri and curvipalpata sp.
has the eighth segment basally modified with a thin, marginal strip of greater
sclerotisation, but otherwise the sclerites are simple. The valves are simple,
strongly tapering in butleri, much less so and shorter in curvipalpata,
with a triangular process centrally on the costa. The aedeagus vesica is large,
more or less spherical, with spining or a cornutus subbasally; in curvipalpata
is also more general scobination.
female (butleri) has the seventh sternite reduced, flanked on each
side posteriorly by pockets that presumably accommodate the long, tapered valves
of the male in copulation. The ostium is situated relatively posteriorly within
the eighth segment. The ductus is long, expanding over the distal third into the
bursa. It is corrugated over this portion; a narrow strip of this corrugation
extends basally to the ostium. The bursa is twice as long as broad, and has a
slight constriction at two thirds, being scobinate on both sides of this but
more intensely so where it occurs. The ductus seminalis arises laterally from
the larger, more basal section of the bursa.
butleri Leech has been recorded feeding as a larva on Castanopsis
in Japan by Miyata (1983) and reported by Sugi (1987) to prefer dried leaves (a
herminiine characteristic). The larva was illustrated by Sugi and is a finely
speckled brown with a fine pale yellow dorsolateral line on each side. There is
a prominent pair of tubercles on A8.
