Wiedemannia brevilamellata Wagner, 1985: 86 [new name for W. alpina Vaillant, 1953 ]. Syn. nov. Original type data. Claix (Isère) à 350 m ( 21 Juin 1951 ) (‘L’unique exemplaire quej’ai capturé ayant été conservé dans l’alcool’). Type material examined. Wiedemannia alpina Vaillant : NEOTYPE ♁ by present designation ( Fig. 5a ) (slide mounted): Affluent de la Gresse , près de Gresse , Vercors, Isère [ France ], 15.VII.1968 [ GBIFCH00603116 ], neotype encircled in red ( Fig. 5a ) on slide with two specimens ( MZLS ).

Remarks. An excellent figure was given in the original description of Wiedemannia alpina Vaillant (1953: 61) ; the species was also illustrated in Vaillant (1965: 166–167 , figs 5g , 5h), but by error was labelled in the figure caption as W. ( W. ) rhynchops ssp. mirousei . The W. alpina Vaillant material is lodged in MZLS and includes specimens from various regions but not the type locality. Vaillant mentioned that the only specimen collected on 21 June 1951 near Claix (Isère, à 350 m elevation), the holotype , was kept in alcohol, which was why Vaillant could not give details on color. FIGURE 5. Wiedemannia debilis Collin. a, slide with neotype encircled in red and additional male specimen; b, neotype, lateral view; c, male terminalia, lateral view (photos MZLS). It is presumed that Vaillant’s alcohol collection is now lost and none of the specimens available are from the type locality “Environs de Claix, Isère”. Therefore, we concluded it appropriate to designate a neotype from the available material in order to fix the species’ identity.
