Formica cordieri BONDROIT, 1917

Formica cordieri BONDROIT, 1917 [type investigation]

This taxon was described by BONDROIT (1917) as gyne in the key. No type locality, collector, nor date was given. Examined were three type specimens from MSNB Bruxelles: one gyne labelled “Orne-6-Longny Collection E.Cordier”, “ Formica cordieri Type Bondr.”; one gyne labelled “Hte Savoie de Gaulle”, “ Formica v. cordieri Type Bondr.”, and one gyne labelled “Sayat P. de D.”, “ Formica v. cordieri Type Bondr.”. The synonymy with Formica pratensis is obvious: All three gynes belong to the hairy N-morph as defined by SEIFERT (1992). For separation of N- and P-morphs, see also below and Figure 29 .
