This report presents the third part of the results of a taxonomic revision and examination of the actual, reputed or potential type material of bees of Swedish origin. Focus is on the status, depository, type locality, condition and history of name-bearing specimens. Here, 21 taxa have been examined. Lectotypes are designated for the specific taxaAndrena cinerascens Nylander, 1848, A. nanula Nylander, 1848, Coelioxys hebescens Nylander, 1848 (now forma of C. rufescens Lepeletier & Serville, 1825), C. simplex Nylander, 1852, Osmia corticalis Gerstaecker, 1869, O. mitis Nylander, 1852 (now Hoplitis m.) and the in- fraspecific taxon Andrena marginata var. nigrescens Aurivillius, 1903 (now subspecies of A. marginata) (bold= valid epithet). An already labelled but unpublished lectotype of Co- elioxys mandibularis Nylander, 1848 is validated. Osmia laticeps Thomson, 1872 (spec. rev.) is found to be a senior synonym of Osmia hyperborea Tkalců, 1983 and a valid name. Re-evaluations are made of the reputedly enigmatic specific taxa Apis rybyensis Linné, 1771, A. cariosa Linné, 1758 and A. obscura Linné, 1764. According to a cabinet species label by Linné’s disciple Thunberg, A. rybyensis is identical to Apis albipes Fabricius, 1781 (now Lasioglossum a.). Apis rybyensis is here classified as a nomen oblitum. Apis cariosa and A. obscura are probably not bees. Further taxa treated are Halictoides dentiventris Nylander, 1848 (now Dufourea d.), Halictus fasciatus Nylander, 1848, H. arenosus Ebmer, 1976 (now subspecies of H. leucaheneus Ebmer, 1972), Lasioglossum boreale Svensson, Ebmer & Sakagami, 1977, Osmia svenssoni Tkalců, 1983, Nomada fusca Schwarz, 1986, Apis arctica Quensel, 1802 and Bombus hyperboreus Schönherr, 1809.

Moreover, the species H. leucaheneus does not occur in Finland or Karelia (Söderman & Leinonen 2003) while it is characteristic for the sandy areas in Skåne where both Dahlbom and Boheman collected (LAN pers. obs.). These circumstances point undisputably to southern Sweden, with all probability Skåne, as type locality and that the 2♂♂ are authentic, just as Ebmer concluded. The 2♂♂ conform to the current common interpretation of the species Halictus leucaheneus Eb- mer (as in e.g. Pesenko & al. 2000, Amiet & al. 2004). The species H. leucaheneus Ebmer, 1972, represented by its subspecies arenosus Ebmer, 1976 (Fig. 2), is redlisted as VU, vulnerable, in Sweden (Gärdenfors 2005). According to Ebmer (1988a), the ssp. arenosus occurs in the temperate zone of Europe (the nominate ssp. leucaheneus is East Asian). Figure 3.

The typification validates the synonymy nigriventris (Zetterstedt, 1838) (as in e.g. Amiet & al. and provides a type locality. 2004, Scheuchl 2006). The synonymy has been listed for over a century (Thomson 1872: 244, Friese 1891: Osmia corticalis Gerstaecker 1869: 331 262, Dalla Torre & Friese 1895: 72, Schmiedeknecht Lectotype ♂ ZMHB [here designated]; GERMANY, 1907: 123, Friese 1911: 123, Blüthgen 1930: 810, Pommern, Garz; Deutschland [printed] Garz Triepke Scheuchl 1996: 110, 2006: 178, Schwarz & al. 1996: S.

Thomson based the description on both sexes. No particular locality was mentioned but just “Sällsynt; troligen utbredd öfver hela Skandinavien” (= Rare; probably distributed over the whole of Scandinavia). Below the cabinet species label “laticeps” in Coll. Thomson (ZML) there stands only a single specimen, a ♀. Why there is no further (such as ♂) material is not known. Tkalců (1983: 154) designated and labelled the ♀ specimen as lectotype. He also reported that the specimen was identical to Osmia uncinata Gerstaecker, 1869, and accordingly concluded that O. laticeps Thomson was a junior synonym. Such a synonymy, but without the study of Thomson’s type material, has been listed before and after Tkalců’s lectotypification of O. laticeps (viz. Schmiedeknecht 1885-1886: 84, 1907: 123, Friese 1891: 262, 1911: 121, Dalla Torre & Friese 1895: 72, Dalla Torre 1896: 414, Ducke 1900: 257, Vikberg 1986: 82, Zanden 1986: 73, Janzon & al. 1991: 94, Schwarz & al. 1996: 128, Banaszak & Romasenko 1998: 123, Söderman & Vikberg 2002: 57, Scheuchl 2006: 181).
