Abstract For Sten'c taatn'basalis Hampson, 1900 ,a new name, kagii ,is given, because the
specific name is preoccupied by Warren, 1895 .A close relative forrner lyconfused with
atn'basalis in Japa nis describe das a new species, fiavopunc btaas,ed on specimens from Japan
and Primorye distric tR,us$ia.
Key words Pyralida eE,pipaschiina eL,opidognz aS,ten'c tsay,nonym, helotype ,paratype.
Recently it became apparent that two closely similar species had been mixed up under the
name of Sten'c toar LePidogma atribasalis in Japan (of S.hibuya, 1927; Mutuura, 1957;
Inoue ,1959 & 1982) . Moreover, the junio rauthor found that two species had also been
collected in the Primorye distric tof Far-eastern Russia.
In order to clarify which of the two is true atn'basalis, the senior author tried to examine
the type-serie sof that species now preserved in the Museum fUr Naturkunde, Berlin ,and
he was able to see and dissec ta female paratype (Fig 5.) labelle "dSutschan, 90, D6rr[ies]",
through the good oMces of Dr W. Mey. A male paratype with the same labe lin coll.
British Museum (N .H.), London, was examined by Mr M. Shaffe rupon his request. As a
result the authors have convinced that the species illustrate bdy Mutuura, 1957, and Inoue,
1959, 1982 & 1992 (c i&" 4 genitalia )is true atribasalis and the other is a new species.
Since Sten'c taatn'basalis Hampson, 1900, is ajunior homonym of S. atn'basalis Warren, 1895,
from Queenslan da ,new name will be given to the former.
Selis ,1992, considers atribasalis Hampson a juni osyrnonym of Sten'c taasopialis (Snellen,
1890) from Darjeeling ,but the senior author's cemparison of the two species at the British
Museum (N. H.) revealed that the former is specifically distinc ftrom the latter.
In order to decide generic placement of the two species concerned in this paper, the senior
author examined male specimens of Lapidagnz alamarical i(sMann )(Sout Ehurope and
Middle East) <Fi g6.) and Sten'c dtiavital (isGuene e()th Seundalan d()Fi g7.) ,the type species
of the respective genera. In the structure of male genitalia the two speeies are quite
distinc tfrom L. taman'cali sin the shape of uncus, valva and aedeagus and more similar to
S. divilal isT.herefore ,the authors will place them in Sten'c lfaollowin gSolis ,1992,
The senior author expresses his thanks to Dr W. Mey, Zoologische sMuseum an der
Humboldt-Universittit ,Berlin (abbreviat aes dZMHU), and Mr M. Shaffer ,Department of
Entomology, British Museum (Natura Hlistory) L,ondon (abbreviat aes dBMNH), for their
kind assistance in various w'ays.

Although this species has been recorded from southern part of Japan (Shikok uK,yushu,
Amami-Oshima), material critically examined by the authors are from Hokkaido and
Honshu.
Caradja,
1925:313, recorded S. atn'basalts from "Canton", China ,but specimens he
identifi eshdould critically be re-examined for confirmation. L. atribasalis of Yang, 1977 :
192 ,pl. 8 : 4, from China, and of Park, 1983 : 400, pl. 27 : 442, from Korea, should also be
reconsidered.
