Shinohara, Akihiko, Kramp, Katja & Taeger, Andreas, 2022, The Pamphiliinae of the Russian Far East and Korea (Hymenoptera, Pamphiliidae), Zootaxa 5167 (1), pp. 1-251 : 75

Pamphilius latifrons group

The member of this species group is characterized as follows: upper part of head pilose; facial crest in male rather strongly swollen, bluntly carinate; antennal flagellomere 1 1.7–2.2 × length of flagellomere 2; right mandible bidentate with only basal shoulder to apical tooth; left mandible tridentate, but middle tooth low; wings hyaline; forewing with cell C glabrous; femora entirely pale. Ovipositor sheath appendage small, inconspicuous. Male genitalia ( Fig. 93g ): proximal ventral arm of gonostipes normal; apiceps very broad; valviceps rather long, bent outwardly and directed below, without conspicuous dorsoapical process.

Only one Palaearctic species is known ( Shinohara 2002b), which occurs in the Russian Far East. It was formerly regarded as an isolated member of the P. vafer group ( Beneš 1976) or the P. histrio group ( Achterberg & Aartsen 1986). No molecular data are available. The larvae feed on Salicaceae ( Populus , Salix ).
