O KARSHOLT & T RUTTEN Zoologisk Museum, Copenhagen, Denmark IPK, Gatersleben, Germany THE GENUS BRYOTROPHA HEINEMANN IN THE WESTERN PALAEARCTIC (LEPIDOPTERA: GELECHIIDAE) Karsholt, O. & T. Rutten, 2005. The genus Bryotropha Heinemann in the western Palaearctic (Lepidoptera: Gelechiidae). – Tijdschrift voor Entomologie 148: 77-207, figs. 1-422. [ 0040-7496]. Published 1 June 2005. The genus Bryotropha Heinemann in the western Palaearctic is revised for the first time. A to- tal of 36 species is recognised. Nine species are described as new: B. horribilis sp. n., B. italica sp. n., B. nupponeni sp. n., B. wolschrijni sp. n., B. heckfordi sp. n., B. phycitiniphila sp. n., B. sutteri sp. n., B. hendrikseni sp. n., and B. hulli sp. n. Representatives of two possible further species are described but, due to insufficient material, not formally named. One new combina- tion is introduced: Bryotropha sabulosella (Rebel, 1905) comb. n., and twelve new junior synonyms are proposed: B. tachengensis Li & Zheng is synonymised with B. rossica Anikin & Piskunov; B. glabrella Heinemann with B. desertella (Herrich-Schäffer), B. brevipalpella Rebel with B. plantariella (Tengström); Gelechia galbanella var. haareki Strand with B. galbanella (Zeller), B. cinnamomea Turati with B. figulella (Staudinger); B. mulinoides Amsel and B. zannonicola Hartig with B. pallorella Amsel; B. inexpectella Nel with B. plebejella (Zeller); B. saralella Amsel with B. dryadella (Zeller); B. dufraneella Joannis and B. novisimilis Li & Zheng with B. similis (Stainton), and B. ambisenectella Li & Zheng with B. svenssoni Park. The following taxa are transferred to the genus Stomopteryx Heinemann: B. subnigricella Dufrane, 1955 (comb. n.), B. neftensis Dufrane, 1955 (comb. n.), B. neftensis f. anomalella Dufrane, 1955 (comb. n.), B. nigricella f. griseella Dufrane, 1955 (comb. n.). Lectotypes are designated, in accordance with , article 74.7.3, for the following species: Recurvaria domestica Haworth, 1828, Lita punctata Staudinger, 1876, B. arabica Amsel, 1952, L. tachyptilella Rebel, 1916, L. purpurella Zetterstedt, 1839, Gelechia flavipalpella Nylander, 1848, G. desertella Douglas, 1850, G. figulella Staudinger, 1859, G. plantariella Tengström, 1848, G. cinerosella Tengström, 1848, G. serrulatella Tengström, 1848, G. galbanella Zeller, 1839, G. imperitella Staudinger, 1859, B. gallurella Amsel, 1952, B. pallorella Amsel, 1952, B. mulinoides Amsel, 1952, B. saralella Amsel, 1952, G. basaltinella Zeller, 1839, B. umbrosella fulvipalpella Joannis, 1908, R. affinis Haworth, 1828, G. tectella Herrich-Schäffer, 1854, G. similis Stainton, 1854, G. thuleella Zeller, 1857, G. confinis Stainton, 1871, G. obscurecinerea Nolcken, 1871, G. (B.) fuliginosella Snellen, 1882, B. dufraneella Joannis, 1928, G. senectella Zeller, 1839, B. obscurella Heinemann, 1870, B. phoebusella Millière, 1876. The name B. vondermühlli Nel & Brusseaux, 2003 is corrected to B. vondermuhlli. Adults, as well as male and female genitalia are described and illustrated. Keys are provided for male and female genitalia. Distribution maps are given for each species. O. Karsholt, Zoologisk Museum, Universitetsparken 15, DK-2100 København Ø, Denmark.
