Allodia (Brachycampta) alternans (Zetterstedt, 1838) Mycetophila alternans Zetterstedt, 1838: 866 Brachycampta alternans; Lundström 1909: 24, figs 26 & 27 nec Brachycampta alternans; Coquillett 1910: 515 nec Brachycampta alternans; Dziedzicki 1915: 11, figs 129 & 130 Allodia alternans; Edwards 1921: 123, fig. 9 nec Mycetophila alternans; Edwards 1924: 163 Allodia alternans; Edwards 1925: 608 ? Allodia delicata Ostroverkhova, 1977: 78, fig. 5 Material. Holotype, sex unknown, lacking abdomen, on the same pin as a male Exe­ chia spinuligera Lundström, 1912 [SPM­005153, mounted on slide, without coloured tag, labelled: M. alternans Zett ď. (M. fusca Ψ) Karungi] – Sweden: NB, Karungi, 28. August 1821. Neotype (Fig. 3). Male [SPM­005726, mounted on slide, MZLU] – Sweden: LU, Jokkmokk, Kaltisjokk at Messaure, barber traps 101–120, 0 2. September ­ 0 4. October 1971, leg. K. Müller. The first specimen above is the type of Mycetophila alternans Zetterstedt, 1838 as can be decided by its co­occurrence with an Exechia spinuligera Lundström 1912 on the same pin as well as the label giving the name and type locality "Karungi". Both these facts are mentioned in the description given in Zetterstedt (1838: 866). Unfortunately the abdomen of the type specimen is lost and without reference to the genitalia the true identity of the type cannot be established beyond subgenus level. Allodia (Brachycampta) alternans apparently has been mixed with A. (B.) grata (Meigen, 1830) by several authors (e.g. Coquillett 1910; Dziedzicki 1915). Edwards (1921) illustrated A. (B.) alternans in accordance with Lundström's (1909) interpretation, and this has later become the prevailing usage of the name by subsequent authors (e.g. Edwards 1925, Zaitzev 1984, 2003). Nevertheless, as Edwards (1924) did not examine the "Insecta Lapponica" collection he reported the type as missing and referred to a male labelled "Bjorn" as being in co­ordinance with his interpretation of Allodia alternans. The specimen labelled "Björn", however, belongs to ...
