Abstract The Japanese species of the genus Lobesia are revised. The monophyly of the genus is supported by the possession of four autapomorphies. Eight species occurring in Japan are classified in two subgenera : seven species belonging to Lobesia and one to IVbolobesia nov, Three new species, Lobesia (Lobesia) argula, L, (L.) virorlenta, L, (L,) Jtezsudoi, are described. Lobesia (L,) bicinctana (DupoNcHEL) is newly recorded from Japan. Adults, wing venation, and genitalia of both sexes are illus- trated. Host plants are listed. Keys are provided for all the known subgenera and the Japanese species,

Key words Tortricidae, Olethreutinae, Lobesia, TVbolobesia, Japanese species,

Introduction

The of the tortricid genus Lobesia are so uniform in the coloring and rnarkings of the forewings that they are often very difficult to separate on the external characters, The genus contains more than one hundred already described species, which are mainly distributed in the Holarctic and the Indo-Australian Regions. Five species have hithert'o been known to occur in Japan: botrana ([DENIs & ScHIF- FERMULLER]), reiiqztana (HVBNER), aeolQPa MEYRIcK, mieae KAWABE, coccoPhagu FALKovlTsH (KAwABE, 1982). No revisional study of the Japanese Lobesia has been proposed up to the present, In the present paper eight Japanese species;) are dealt with; seven belong to the subgenus Lobesia and one to the subgenus jVlaolobesia, which is here proposed for L.

coccophaga FALKoviTsH. Of these species, three are described as new and one is

recorded from Japan for the first time.

i)We ornitted L. botrana ([DENis & ScHiFFERMOLLER]) from the Japanese fauna, though it was in the collection of the recorded by MATsuMuRA (1931), No voucher speeimens have been found to a Entomological Institute, Hokkaido University, and it seems likely that the record was due misidentification.

GenusLobesia GuENEE

Small in size; wing expanse : 9-15 mm, Head clothed with loosely appressed scales at vertex; face smooth. Antenna filiform, about O.5 times the length of forewing. Labial palpus ascending; second

segment densely clothed with long scales beneath.

Therax with a posterior crest. Hind tibia in male with hair pencil on inside of its proximal end (Fig. 19) or sometimes hair pencil lost (see the description of abdomen below).

Abdomen in male with a pair of elongate pouehes situated in each side of 2nd abdominal sternite (Fig. 15). The pouches opening to outside by a slit, containing numerous oval scales (Figs. 15- 17) or hair-like scales. This structure probably serves as a scent organ in cornbination with tibial hair pencil described above; the hair pencils are supposed to have the function ef distribution of a scent substance secreted in the

pouches. The abdominal pouches are occasionally lost. A correlation is observed between the degree of the development of tibial hair pencil and that of the abdominal pouches (FALKov'ITsH, 1962: 881, table 2). Second abclominal sternite triangular in male (Fig. 15: S II), the vertex reaching the following sternite; in female it is of the

normal tortricid type,

Forewing (Figs. 13, 14, 20-26) smooth, with pterostigma indicated by a patch of - corrugated wing membrane between Sc and R, (Figs. 13, 14), it well defined (Figs. 20 23, 25, 26) or ill-defined (Fig. 24); costal fold in male absent; Ri from just before middle; R2 from 1/2 to 2/3; R, and R, sinuate (Figs. 20-23, 26) or straight (Fig, 24), these two veins not reaching costa (Fig. 13); R3, R4 and Rs approximated at base; R4

to costa; Rs to termen; chorda running from upper margin of cell between Ri and R2

to posterior margin between R, and Rs (Figs. 20-25) or chorda absent in coccophaga (Fig. 26); CuA2 from about 3!4, Forewing ground color usually white ochreous to ochreous, with darker complicated markings (Fig. 18). Hindwing (Figs, 20-26) typical for the family, i, e. subtrapezoidal or semiovate, or sexually dimorphic in some species, e. g. reliqztana and its allied species : in female hindwing of ordinarily subtrapezoidal type (Fig. 21); in male it distinctly narrower than that in female, with a more acute apex and with almost straight (Fig. 20) or even concave termen. Rs and Mi closely approximated toward base, or occasionally stalked (coccoPhaga as shown in Fig, 26); M, parallel to M3; M3 and CuAi closely approximat- ed at base or stalked; CuA, from ll2 to 2f3; CuP present or absent. Male genitalia (Figs. 27-38). Tegumen weak; pedunculus with an acute process (apodeme of tergal flexor of valva (m4), see KuzNETsov and STEKoLNIKov, 1977 : 82) -31, in anterior eclge; uncus vestigial or absent; socius distinct (Figs. 27 34), clothed with modified scales, or socius absent (Figs. 32, 33); gnathos usually a weak transverse band, Aedeagus usually of a slender tube, sometimes armed with some minute dents

on its outer surface (Figs, 35-38); cornuti usually absent. Valva slender; sacculus

with a scalloped edge or simple, usually separated from cucullus by an incision; spine clusters Spci and Spc2 present, these separated or rarely united to form a single cluster

of spines,

Female genitalia (Figs, 39-46), Sterigma variously formed: e. g. pear-shaped - - (Figs. 39 42), tubular

Remarks. The monophyly of the genus is supported by the following four

autapomorphies :

1) Forewing with pterostigma, This specialization occurs uniquely within the Olethreutinae.

2) Presence of scent organ formed by combination of abdominal pouches and tibial hair pencils in male. This structure is unique within the Olethreutinae (FALKovlTsH, 1962: 881).

3) Pedunculus with an acute process in its anterior edge, A similar structure also appears in Ancl,lis HUBNER and its allied genera in the Olethreutinae (see RAzowsKi, - 1989 : 267 268). We have no evidence to show positively that this resemblance is due

to synapomorphy,

4) Sterigma situated on membranous pocket under 7th abdominal sternite. A

simi]ar formation also appears in the subtribe Gatesclarkeanina (Ukamenia OKu, Hiroshiinouea KAwABE, Gatesckzrkeana DIAKoNoFF) in the Olethreutinae (see RAzow- sKI, 1989 : 282). It seems most probable that this resemblance is due to convergence, Lobesia is subdivided into eight subgenera as follows :

Host plant. Loniceva ioponica THuNB. (Caprifoliaceae). Larvae feed in the buds and flowers of the host in spring.

Remarks. L. coccoPhciga is somewhat similar superficially to reliquana and its

allied species, from which it may be easily separated by the tawny head and the distinct, strong brown markings in forewing, This species is quite distinct from other members of the genus in having the peculiar characters of venation and genitalia given under the description of the subgenus IVbolobesia.
