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).
