Ypsolopha dentella ( Fabricius, 1775) [ Fig. 5 ]

Phalaena (Tinea) dentella Fabricius, 1775: 667 [type locality: Sweden]. = harpella [ Denis and Schiffermüller, 1776]: 136 ( Tinea ).

= affinitella Staudinger, 1892: 392 (Cerostoma) . n. syn.

New records: CHINA – [Jilin] 43, 4Ƥ, Mt. Changbaishan, 13 – 19 VII 1974; 2Ƥ, 26 – 28 VII 1974; 2Ƥ, ditto, 4 – 9 VIII 1974, IZCAS. [Heilongjiang] 13, Yichun, 9 VII 1963; 83, 7Ƥ, Wuying, 23 – 30 VI 1981, [GSN: IOZ-09005 (3), 0 9006 (Ƥ)], IZCAS.

Distribution: China (new record: Northeast), Russia ( Zinchenko and Ponomarenko 2008), Mideast Asia, Europe and North America.

Remark: Staudinger (1892) described Ypsolopha affinitella , based on a male specimen from Kentei Gebirge (now, Malkhanskiy Region), Russia, as a separate species from the European Y. dentella on account of differences in the background color and the oblique streak on the dorsal patch in the forewing. However, these pattern differences actually overlap with variation observed in Y. dentella . To assess the identity of Y.

affinitella , we examined a photo of its holotype provided by Dr. Wolfram Mey in the Museum für Naturkunde, Humboldt-Universität, Berlin, Germany ( Fig. 5 ). In addition, the first author (JCS) examined one specimen in the Natural History Museum (BMNH), London, which was identified by Staudinger as Y. affinitella . These affinitella specimens are indistinguishable from Y. dentella and thus, we propose that they are synonyms.
