Polynema (Doriclytus) vitripenne ( Foerster, 1847)

= Polynema depressicollis Hellén, 1974: 20 , syn. nov.

Material examined. N: Espoo (6683:3370), 4.x.1982, M. Pulkkinen (1 ♀, FMNH). Ta: Janakkala, Vapari (6758:3371), 15.x.2011, V. Vikberg (1 ♀, VVCT).

Remarks. Polynema depressicollis is here synonymized with P. (Doriclytus) vitripenne ( Foerster, 1847) . Unfortunately, all specimens (of both sexes, unspecified in the original description other than by their localities) of the type series of P. depressicollis , including its holotype from Parikkala, are lost from FMNH. However, its original description (of the female sex) fits perfectly the redescription of that of P. (Doriclytus) vitripenne by T*©ංൺඉංඍඌඒඇ & FංൽൺඅǤඈ (2006), so there is no doubt about its identity, and therefore no neotype designation is necessary for P. depressicollis . Furthermore, Hൾඅඅඣඇ (1974) indicated that his P. depressicollis is the same species as the species from Denmark misidentified as P. euhariforme Haliday, 1833 by Bൺκκൾඇൽඈ*©ൿ (1934), who illustrated it, and which was shown to be conspecific with P. (Doriclytus) vitripenne by T*©ංൺඉංඍඌඒඇ & FංൽൺඅǤඈ (2006) based on O. Bakkendorf’s voucher specimens. Distribution. Palaearctic Region ( Belgium, Czech Republic, Denmark, Germany, Russia, Sweden, United Kingdom) (T*©ංൺඉංඍඌඒඇ & FංൽൺඅǤඈ 2006; Nඈඒൾඌ 2019; Sൺආκඈඏග et al. 2020). New species record for Finland.
