lntroduction
The genus Microthauma was erected by Walsingham in 189 I based on Miciwthauma metal-
Zijle rWaalsingham, 1891 from South Africa ,and currently includes two other species,
Microthat{ma glycineZ lKauroko, 1964 from Japan (Kyushu O,kinawa) and M. Iespedezella
Sekajaeva,1990 from SouthernPrimorye,theRussian FarEast.AlthoughM. Iespedezella

has not hithert obeen re:orded other than from the type localit yon,e ef us (Hiran foo)und
that it occurs in Matsumoto city, Nagano Prefecture ,central Japan .Examinatio nof speci-
mens recently reared by Mr Kogi (Sappor or)evealed that thi' sspecies also occurs in
Hoklcaide,

Hostplant sL.e,spedeza bicoto r(new record) and L. c)･,rtobotrya (Leguminosae).
Biology. The mining habit and cocoon of this species resemble those of M. glycinella,
which is a leaf miner of Glycin emax and Pueraria lohata (Leguminos (aKeu)roko ,1964),
The early insta rlarva emake a linea rmine on the hostplan tfsrom near the margin to the
other side of the leaf crossing the midrib, se that the apical part of the leaf is withered and
changes to yellowis hgreen (Fi g2,C). The mine changes abruptly to form a creamy white
to pale yellow irregul abrtotc hon the apical part of the leaf (Fi gI.D). There is one larva
leaf.The larvae
per mine, and one mine per mature make a white spindle-shaped cocoon
(abou 5t-6 mm in length) ,which is covered by a thick H-shaped silken roof (abou 1t.0 mm
in length) as that of M. glycinel l(aFig .IE). The pupae have a single characteristic projec-
tion at the apex of the head (Fig .IF) , The adults appear in Matsumoto City ,Nagano
Prefe¢ture from July to August, but in Hayakita-cho, YUbutsu-gun, Hokkaido in mid
September .One of us (Hiran oobs)erved that the adults also appear in October in Matsumoto
City,Remarks.
This species resembles the spring form of M. glycinell aKuroko from Japan in
appearance (Seksjae v1a9,90) ,but is readily distinguish efdrom it by it ssomewhat larger
win.crspan (7- 9mm in M. Iespedezel l6a.,5-7 mm in M, gl yci.nelta), the forewin gpattern,
and the male and female genitali aI.n the wing patter ni,n panicula rwh,en the adult is rest-
ing, the dorsal leaden-metalli cstreak forms a semicircular patch in M, tespedeiella ,while it
is VLshaped in M. gl.ycinel t(aFi gIsA-B, 2A-B). In the male genitali tah,e valva does not
have an incisio annd the base of the acdeagus is broader and truncate (Fi g3,) ,In the female
genitali ath,e apophysis anterioris is slenderer and longer but the apophysis posteriori sis
shorter than in M. gl.vcinell aan,d the ovate sclerotized plat ein the 7th abdominal segment
is]ackinginM. te,spedezell(aFig4.).

Biology. As describcd above, the larva of this species makeg a 1inea rand blotch mine
(Kuroko 1,964, 1982) ,The early insta rlarv amakes a linea rmine on the hostplan tfsrom
near the margin of the leaf and across the leaf to the other side, The linea rmine is broad-
ened, and becomes a blotc hmine at the apex of thc lcaf (Fig 2.C).
Remarks. Oku (2003 )noted the presenc cof this species in lwate Prefectur eH,onshu,
Japan .It was also collected in the faunal survey of moths ¢ onductcd by the National
Scienc eMuseum in the gardens of the Jmperial Palace ,Tbkye. Thus, the species was
confirmed to be widely distribut ethdroughout Honshu, other than Kyushu and Okinawa,
Japan .Park (1983 re)corded this species from South Korea.

Walsingham (1891 c)haracterized the genus Microthauma only by the more developed
drooping labia lpalpi ,He also discrirnina tMeicdtvthauma metall(fera, type species of the
genus, by the wing patter nand body coloration, but did not refer to the mining habit and
genita lcharacters, Later, Kuroko (1964 )characterized the genus by the lengt hof the labial
palpi ,the genita clharacters and wing venation.
The unique mining habit t,he depresse dbasa lpart of the aedeagus and the single projection
at apex o'f the pupal head were seen in M. gZycinetl aand M. tespedezel laW.e consider that
these arc possibl aeutapomorphies of the genus Microthaitma.
