Key words Boarmiini ,Geometridae ,new species, new subspecies, Taiwan,
Recently I examined some Boarmiin ispecimens taken at Mts Anmashan, Taichung Co., in
Taiwan, by Messrs C.-M. Fu and H.-R. Tzuoo, and fbund some interesti nspgecies among
them. In this paper ,I will describ etwo new species of Ramabia Inoue and flsiinic Wiasrren,
and two new subspecies of Dufibphyle crgitata (Butl aendr) CZleor aleucophae a(Butl efrro)m

Ineue (195 31:0) erected the genus Raniobia to accommodate Boaxmia basijusear iLaeech,
1891 ,together with a new species, R. medlodivisa Inoue, l953 . Both species were described
from Japan, and late rmediodivisa was recorded from Korea by Shin (198 32:37) . The genus
Ramobia is now recorded from Taiwan fbr the firs ttime.
The characters of the male and fernal geenital isahow that this species is more closely related
to mediodtvtsa than to haspttsca nt'haou,gh in appearance it is mere similar tD the latter.
This species is also similar to the fbllowin gspecies describe dfrom VVest China by Wehrli

catachi:psa and
catociua Wehrli (Ta-tsi'en -lTohue)y, have not hithert obeen illustrat edI .examined the
type specimens ofthern preserved in ZFMK, without dissecti oofnthe genitalia . Dr Sttining
kindly examined their genital ifabr me to cenfirm the identificat iooftnhis species. He will
write his paper on the genus Ramobia from China in the near future,
This new species is an autumn moth like the two known species of Ramobia, and may be
confined to high altitude above 2,eOO m in Taiwan.
