Osada, Yohei, Sakai, Makoto & Hirowatari, Toshiya, 2015, A revision of the genus Morophagoides Petersen (Lepidoptera, Tineidae) from Japan, Zootaxa 3973 (2), pp. 351-368 : 364-366

Morophagoides yakuensis sp. nov.

[Japanese name: Yakushima-shiitake-ohirozukoga] Figs. 1 H, 10A–B

Diagnosis. In the female genitalia, the margin of the ostium bursae projects beyond a pair of setose lobes, the lateral margin of ostium bursae is angular, the concavity of the posterior margin of the ostium bursae is about 1/2 as long as the ostium bursae, the antrum is stout and about 1/2 as long as the apophysis anterioris.

Description. Length of forewing 7.7mm; forewing expanse 16.6 mm.

Etymology. The name yakuensis , “Yakushima” in Latin, refers to the Yaku Is. distribution of the new species.

Wing ( Fig. 1 H): The basic color pattern of the forewing is regular.

Male genitalia: Unkown.

Female genitalia ( Figs 10 A–B): Margin of ostium bursae projecting beyond a pair of setose lobes. Concavity of posterior margin of ostium bursae about 1/2 as long as ostium bursae. Lateral margin of ostium bursae angular. Antrum stout and about 1/2 as long as apophysis anterioris.

Distribution. Japan: Yaku Is. (Kagoshima).

Specimen examined. HOLOTYPE ♀, [Yaku Is.] (Kagoshima Pref.) Shiratani, Yakushima-machi, 16. ix. 1978, S. Moriuti leg, deposited in Entomological Laboratory, Osaka Prefecture University (ELOUP).

Remarks. This species has only been collected in the Yaku Is. The larval biology is unknown, and it has not been reported that shiitake mushrooms are injured by this species.
