Abstract Archinemapogon bacurianus Zagulajev, 1962 is newly recorded from Japan. The female genitalia of this are described for the first time. The adults and male genitalia are also described in detail.

Key words Fomes fomentarius, fungus, , new record, Tineidae.

Introduction of wing venation, the forewing and hindwing were cleaned to remove scales with a raccoon-fur brush in 70 % EtOH, and The members of the subfamily Nemapogoninae of the Tineidae stained with acetocarmine in 6 hours. feed on fungi. In Japan, six species belonging to three different genera of the subfamily, Dinica endochrysa（ Meyrick, 1935）, granella（ Linnaeus, 1758）, N. masoplaca Description （Meyrick, 1919）, N. robusta Gaedike, 2000, N. bidentata Xiao Archinemapogon bacurianus Zagulajev, 1962 & Li, 2010 and Triaxomera puncticulata Miyamoto, Hirowatari [Newly proposed Japanese name: Sujimon-kokuga] & Yamamoto, 2002, are known to occur（ Miyamoto et al., 2002; Archinemapogon bacurianus Sakai, 2013; Osada et al., 2015）. Zagulajev, 1962 : 1044 - 1045 ; Zagulajev, 1964: 371-373. fig. 329. The Archinemapogon of the subfamily was established by Diagnosis. Zagulajev（ 1962）, and it consists of nine species, A. yildizae Ground color of the male and female forewings is Koçak, 1981 , A. assamensis Robinson, 1980 , A. bacurianus yellowish white, and there is a dark brown line in the center of Zagulajev, 1962 , A. erasella（ Zeller, 1863）, A. interstitiella the forewing from the apex to the base. In the male genitalia, the （Dietz, 1905）, A. oregonella（ Busck, 1901）, A. rileyi（ Dietz, uncus is divergent, the vinculum is narrower than length of the 1905）, A. schromicus Zagulajev, 1964 and A. ussuriensis saccus and the phallus bears an elongate process near the apex Zagulajev, 1962 from the Europe and the Russia of the Palearctic dorsally. In the female genitalia, a pair of setose lobes is present and the USA of the Nearctic regions（ Zagulajev, 1962 ; in the ostium bursae, the lamella antevaginalis is slightly Zagulajev, 1964; Robinson, 1980; Zagulajev, 1981）. projected posteriorly, and the antrum is about 1/8 as long as the ductus bursae. In this study, A. bacurianus is newly recorded from Japan and Description. the female genitalia are described for the first time with Male: length of forewing 6.5-8.8 mm; forewing redescriptions of the adults and male genitalia. expanse 14.0-18.2 mm. Frenulum consisting of a single bristle. Head: vertex and face roughly clothed with whitish yellow hairs. Antenna filiform, scape and pedicel covered with brown scales. Materials and methods Maxillary palpus clothed with yellowish white and brown scales. Materials examined in this study are deposited in the collection Labial palpus covered with yellowish white and brown scales. of Osaka Prefecture University（ OPU） and Kyushu University Thorax: mesonotum clothed with yellowish white scales, tegula （KU）. dark anteriorly, yellowish white posteriorly; metanotum clothed with yellowish while scales.
