( Fig. 2 )

Chelifera subangusta Collin, 1961: 708 .

Chelifera berdeni Vaillant, 1978: 466 . Nomen nudum.

Chelifera giraudae Vaillant, 1982: 374 . Type locality: Marcols (Ardèche) [ France]. Syn. nov.

Type material examined. Chelifera giraudae : HOLOTYPE ♁ (slide mounted): Marcols (Ardèche) [ France], prairie 8. V. 1964 [800 m]. Slide no GBIFCH00601688 ( MZLS).

Additional material examined. Germany. 1 ♁, Attmannsweiler (westl. Ellwangen), 16.8.1974 ( ZMFK); 17 ♁, Annaberger Bach (near Bonn) from emergence collections ( Caspers & Wagner 1982) (in coll. RW) .

Remarks. Based on male terminalia, specimens of C. giraudae and C. subangusta are indistinguishable. The holotype of C. giraudae was a specimen reared from a larva collected in the freshwater spring Marcols-lesEaux, Ardèche, Massif Central, 800 m. Vaillant’s holotype slide and the eclosion date and locality fit the original description. The species is rarely collected but its distribution area covers Southwestern and Central Europe.

The name C. berdeni was mentioned when RW visited F. Vaillant. At that time he suggested it as a new but undescribed species (F. Vaillant, pers. comm. 1980s)—it is most probably his C. giraudae .
