Introduction
The genus Heleanna Clarke ,1976 is a smal1 genus of the tribe Eucsomini distribut iend the
Orienta land Australian regionsl containing four describe dand one undescribed species
(Clarke19,76; Horak 1996;Nasu,1995,1999;Brown,2005;Horak,2006).Because
et al.,
the members of the genus are externally very similar to each other in appearance, the most
usefu1 characters for recognizing species are the genital ifceature sof both sexes. Horak
(2006 l)iste dseveral characters on the adults supporting the monophyly of the genus, e. g.
face flattene adn, oyate depressio non the basal area of the upperside fbrewin gfille wdith
whitish, modified scales and covered with large d,omed scales, and stalked R, and R, in the
forewing .Until now, only one species, H, fitku Ngaisu, 1999 has been recorded from the
Ryukyus in Japan (Nasu ,l999), and no species from Korea,
During examination of material from Japan and Korea, we fbund two new species of the
genus. We herei ndescrib ethe two new species, with illustrati oofn sadults, genital ianad
immature stages, and discus sthe morphological characters of the immature stages of the
genus.
Materials
and methods
The present study is based on specimens feeding on 7berpini aternata Nakai collected from
Okinawa and on a moth collected in the Garden of the Imperial Palace, [[bkye, Japan ,and a
specimen from Jeju-d oIsland K,orea. The fbllowin gacronyms are used fbr the depositories
of specimens: KNA-Korea National Arboretum, Pochen, Korea; NSMT-National
Scienc eMuseum, rlbkyo, Japan ;UOP-Entomological Laborator yof Osaka Prefecture
University,Sakai,Japan;YNC-Collection YlNasu.

Discussion
The genus Heleanna is distribut eidn the Orienta land Australia rnegions, and fiv especies
including an undescribed one have been recorded to date (Clar kle9,76; Horak et al., 1996;
Nasu, 1995, 1999; Brown, 2005; Horak, 2006) ,As the two new species are describe dfrom
Honshu of Japan and from Korea in the present study, the genus is recorded from the
Palaearcti cregion for the firs ttime, The host-plant sand feeding habits of the fiv especies
are as fbllows ,These larva efeed on seyeral plant sof various familie sand are stem- or
fruit-bore srosme,times leaf rollers: H. physalode f(iMeyric k1,910) feeds on the flower buds

Detailed informatio nhas been given on the immature stages of the three species, H,
melanomochla (Nasu ,1995), H. ,fi{kug i(Nasu ,1999) and H. tuilpinivova, The larvae and
pupae of the three species have several commen characters, The larva has the same chaeto-
taxy: on abdominal segment 9, D2s on acommon pinaculum ,Dl and SDI on acommon
pinaculum and L group trisetos eon a common pinaculum; SV group on abdominal seg-
ments 1, 2, 3, 7, 8 and 9 consisting of 3, 3, 3, 2, 2 and2 setae, respectively. The thoracic leg
of the larv ahas a pai rof enlarged, blade-li kperetars aseltae. Simila rsetae are also found in
several species of Tortricid a(eNas uand "Ibminaga, 2005) .Nasu et al. (2004 s)uggested the
possibili tthyat these enlarged setae are characteristic of larvae that bore int ofruit osr stems
and mine leaves because simi]ar setae are observed jn various familie se,. g. Incurvariidae,
LyonetiidaeP,alaephatidacE,IachistidaeC,osmopterigidaeP,eleopodidae,Heliodinidae,

and Copromorphidae ,and most of these larva eare known as stem- or fruit-bor eorrs leaf
miners. However, the functio nof the setae is unknown and many exceptions are present
within the Tbrtricida e(Nas uand rlbminaga, 2005), Further research is necessary te show
the functio nof the setae. A small circular plate is present antero-dorsad from the ventral
proleg on abdominal segments 3-6 of the larva .The functio nof the plate is unknown, but
the structure is widely distribut eidn the [Ibrtrici d(aKeoma i1,999; Nasu and Tominaga,
2005; Nasu et at,, 2005) .The pupa has three pair sof setae on the clypeus and four pair sof
hooked setae on abdominal segment 10. The shared possessio nof these characters is con-
sidered to support the monophyly of Heleanna though the characters are not peculia rto the
genus.
