Gonatopus jaliscanus sp. n., a new Pincer wasp from Jalisco, Mexico (Hymenoptera, Dryinidae)

Abstract

A new species ofGonatopusLjungh, 1810,G.jaliscanussp. n., from Jalisco, Mexico, is described and illustrated. In the Neotropical region,G.jaliscanusis similar toG.forestalisOlmi, 1998, but it is distinguished by the black mesosoma (except prothorax, mesoscutum, and mesoscutellum that are yellow), and the metapostnotum being granulated and not rugose; inG.forestalisthe mesosoma is completely black and the metapostnotum is granulated and strongly rugose. In the Nearctic region, the new species is morphologically similar toG.currieiKrombein, 1962, but it is distinguished by the dull and granulated metapostonotum; inG.currieithe metapostnotum is shiny and unsculptured. The new species belongs toGonatopusgroup 7. The keys to the females of the Nearctic and Neotropical species of this group are modified to include the new taxon.
