Savoca Walker Gen. rev.
Type species: sarawakana Walker, a junior objective synonym of conglobalis
Walker.
This generic name is available for a closely knit, clearly defined group
of small species that were found distributed amongst the genera Lophoptera and
Gyrtona in previous classifications. They appear from characters of the
male genitalia to be more closely allied to Stictoptera and Aegilia.
The species are relatively small, with rectangular forewings patterned
usually with a distinctive basal zone and a postmedial that is fine, double,
biarcuate, roughly perpendicular to the dorsum. The hindwings often grade paler
basad but are not hyaline.
The valves of the male genitalia are divided into slender, more or less
equal dorsal and ventral arms as in Stictoptera and Aegilia, linked
by a thin, flexible membrane. The saccus is usually trilobed, the central lobe
much narrower than the lateral ones. The uncus (usually long and slender) in all
species except yucca Swinhoe has a prominent ventral subbasal process
that is usually broader and more setose than the rest of the uncus.
In the female genitalita the eighth segment is relatively unmodified,
almost a complete ring, and the signum is usually a circular boss of more
intense scobination in the centre of the bursa (modified to a serrate ridge in S.
yucca).
Non-Bornean species that should be included are: S. plumbeifascia
Hampson (Andamans) comb. n.; S. lophota Turner (Queensland) comb.
n.; S.
plumbisparsa Hampson (N.E. Himalaya) comb. n.; S. chalybsa Hampson
(S. India) comb. n.; S. phaeoxista Hampson (Sri Lanka) comb. n.
