A new species of the genus Gonatopus Ljungh from the USA (Hymenoptera, Dryinidae)

Abstract

A new species of Gonatopus Ljungh, 1810 is described from the USA, Florida: G. jacki sp. n. Morphologically, the new species is similar to G. ashmeadi Kieffer, 1905 and G. agropyrus Fenton, 1921, but it is distinguished by the different shape of the mesoscutum (very slender in G. jacki; broader in G. ashmeadi and G. agropyrus). Published identification keys to the Nearctic species of Gonatopus are modified to include the new species.
