Description of a new species of Gonatopus (Hymenoptera, Dryinidae) from Canada
Year: 2026
Type: article
Abstract: A new species of Gonatopus Ljungh, 1810 is described from Québec, Canada: G. quebecensis sp. nov . Both the female and male are described and illustrated using morphological and molecular evidence. Morphologically, the new species belongs to Gonatopus species group 6 and is similar to the Nearctic G. plesius (Fenton, 1927) and the eastern Palearctic G. pedestris (Dalman, 1818), but it is distinguished by the reticulate-rugose mesoscutum and mesoscutellum, granulate metanotum, and enlarged claw lacking peg-like hairs in the female, and by the slender, transverse, medially broadened dorsal process of the paramere in the male. DNA barcoding supports the association of both sexes and indicates that the species had previously been collected in Québec and Ontario but remained undescribed. Published identification keys to the females of Nearctic Gonatopus species group 6 and to the males of Nearctic Gonatopus are modified to include the new species.
