1A17878BA37B7B7BFF69FBF78957FC99.taxon	materials_examined	Type species: Metacosma impolitana Kuznetzov, 1985, by original designation and monotypy. Redesciption (excluding M. miratorana). Head: Antenna (Figs. 2, 3) in male with a notch near base. Labial palpus (Fig. 3) with second segment expanded distally by scales, roughly triangular, ascending; third segment short, porrect. Thorax: Forewing (Figs. 1, 7) long and narrow, without costal fold in male; M-stem and chorda absent; all veins present and separate beyond discal cell; R 3 approximated to R 4 at base. Hindwing (Figs. 1, 7 – 9) almost equal to forewing in width, with sparse cubital pecten. Hindwing in male with anal margin produced into a free elongate lobe with the outer edge folded upward and embracing a scale pencil from the base of the anal area (Figs. 1, 7, 8); M 2 and M 3 nearly approximated at base and from lower angle of discal cell, CuA 1 from lower margin of discal cell near angle. Abdomen: Hindmargin of S 8 strongly bilobed in male (Fig. 11). Male genitalia (Fig. 10) with valva without basal process; cucullus with a bristled flap produced from dorsal margin near its apex, with one or two strong spines on the apex and three to six similar ones along the ventrodistal margin. Uncus a short process, often distally bifid. Socii elongate lobes with long setae, completely fused with diaphragma. Female genitalia (Figs. 12, 13) with S 7 heavily sclerotized, wide, divided into three areas: raised, semicircular median plate and variously shaped lateral plates. Sterigma funnel-shaped, fused with folded posterior apex of S 7 (ostium bursae behind S 7) (Fig. 13: arrow). Ductus bursae with long, anteriorly bifurcate sclerotization in anterior 3 / 4. Corpus bursae ovate or rounded, spinulose except around signum, with two, rather small horn-shaped signa.	en	Komai, Furumi, Byun, Bong-Kyu, Yamazaki, Saburo (2018): Remarks on the genus Metacosma Kuznetzov, 1985 (Lepidoptera: Tortricidae, Olethreutinae, Eucosmini), with description of a new species from Japan and Korea.

1A17878BA37B7B7BFF69FBF78957FC99.taxon	discussion	Remarks. Metacosma is characterized by the male hindwing with a free elongate fold embracing a scale pencil from the base of the anal area (Figs. 1, 7, 8); the cucullus with a bristled flap produced from dorsal margin near the apex and with one or two strong spines on the apex and three to six similar ones along the ventrodistal margin (Fig. 10); and the seventh sternite of the female consisting of raised, semicircular median plate and variously shaped lateral plates (Figs. 12, 13). All these character states appear to represent synapomorphies for members of the genus. The genus belongs to the Spilonota group, an informal genus group proposed by Horak (2006), comprising Eccoptocera Walsingham, Hendecasticha Meyrick, Hermenias Meyrick, Holocola Meyrick, Lepidunca Diakonoff, Parienia Berg, Protithona Meyrick, Spilonota Stephens, Strepsicrates Meyrick, and Xenosocia Diakonoff. Metacosma shares with members of the Spilonota group the following derived traits presented by Horak (2006): antennal notch in male, extended anal region in male hindwing with upturned anal margin folded over long scale pencil from base, funnel-shaped sterigma fused with S 7, and a tendency for signa to be reduced or lost and bursa to become strongly spinulose. In addition to the above genera the North African Cirrilaspeyresia Razowski (type species: Euxanthis imbecillana Kennel) may belong to the Spilonota group and may be most closely allied to Metacosma. Cirrilaspeyresia imbecillana (Kennel) shares with the Spilonota group the tendency towards reduction of the signa (absent in C. imbecillana) and the funnel-shaped sterigma fused with S 7 (Razowski 1961: fig. 25), but in the drawing of the adult head the antenna has no notch at its base (Razowski, 1961: 675, fig. 3), though there is no indication of its sex. Moreover, this species is similar to members of Metacosma in having the cucullus with strong spines along the outer and ventral margins (Razowski 1961: fig. 11). Prior to this report, five Metacosma species were known mainly from North East Asia (see the checklist below). However, the generic assignment of M. miratorana Kuznetzov is questionable, as no synapomorphies have been identified that would support this assignment, though the species is known only from males. Furthermore, M. miratorana differs from the other species of Metacosma in possessing semioval socii and long basal processes (Kuznetzov 1988: 629, fig. 21). Superficially it is reminiscent of some species of Gypsonoma Meyrick (see also Nedoshivina 2010: 343, pl. 9, fig. 67).	en	Komai, Furumi, Byun, Bong-Kyu, Yamazaki, Saburo (2018): Remarks on the genus Metacosma Kuznetzov, 1985 (Lepidoptera: Tortricidae, Olethreutinae, Eucosmini), with description of a new species from Japan and Korea.

1A17878BA37E7B7EFF69FF788FA7FBB9.taxon	diagnosis	Diagnosis. Metacosma echinophora can be distinguished from other species in the genus by the nearly right-angled sacculus, followed by a deep semicircular emargination in the ventral margin. This species is most similar to M. impolitana Kuznetzov; both have strong spines with a blunt tip in the cucullus and the median plate of the female seventh sternite semicircular, but the valva is more deeply emarginated in ventral margin and the sacculus is more angulate; the lateral plates of the female seventh sternite are more expanded with sinuate posterior margin.	en	Komai, Furumi, Byun, Bong-Kyu, Yamazaki, Saburo (2018): Remarks on the genus Metacosma Kuznetzov, 1985 (Lepidoptera: Tortricidae, Olethreutinae, Eucosmini), with description of a new species from Japan and Korea.

The larva also feeds on cultivated Pinus species in Japan, including P. banksiana Lambert, P. sylvestris L., P. ponderosa Douglas ex C. Lawson, and P. nigra Arnold (Kojima, 1986). Biology. The early instar larva mines the base of needles, causing them to wither. After infesting two needles the larva spins a thick web among winter buds and bores into the basal region of a winter bud and sometimes a young cone. It inhabits the web shelter and deposits resin onto the surface of the shelter, forming a “ resin dome ” (Figs. 4, 5) (Kobayashi, 1967; Kojima, 1986). According to Kobayashi (1967), this species is univoltine, with the larva found from June to September, constructing a cocoon in leaf litter, pupating in autumn, and the adult on the wing in the following May to June. But the adults were collected in August in Iwate, Nagano, Gifu, and Wakayama Prefectures, in September on Yakushima Island, in October on Okinawa-jima Island, and in November on Tokunoshima Island. The larvae are very common on younger trees of less than five or six years old, but rare on mature trees (Kobayashi, 1967). Moths come to light.	en	Komai, Furumi, Byun, Bong-Kyu, Yamazaki, Saburo (2018): Remarks on the genus Metacosma Kuznetzov, 1985 (Lepidoptera: Tortricidae, Olethreutinae, Eucosmini), with description of a new species from Japan and Korea.
