Abstract

Notes are given on the five species of Synergus Hartig, 1840 recorded from Central and South America, including a key for their identification. A new species, S. colombianussp. nov., is described from Colombia. The new species is an inquiline of an unidentified cynipid gall on Quercus humboldtii Bonpl. (Fagaceae). Synergus colombianus is the first Synergus species recorded from Colombia and the most southerly record of this genus in the Neotropical region. The new species is closely related to S. cultratus Ritchie et Shorthouse, 1987, S. filicornis Cameron, 1883, and S. nicaraguensis Díaz et Gallardo, 1998, but differs from these species in characters that are discussed in the text.

Résumé

Nous présentons des données sur les cinq espèces de Synergus Hartig, 1840 reconnues actuellement en Amérique Centrale et du Sud, ainsi qu'une clef pour leur identification. Une nouvelle espèce, S. colombianussp. nov., est décrite pour la Colombie. La nouvelle espèce est commensale d'une galle de cynipide non identifiée produite sur Quercus humboldtii Bonpl. (Fagaceae). Synergus colombianus est la première espèce de Synergus décrite pour la Colombie et la localité la plus au sud pour ce genre, dans la région néotropicale. La nouvelle espèce ressemble à S. cultratus Ritchie et Shorthouse, 1987, S. filicornis Cameron, 1883, et S. nicaraguensis Díaz et Gallardo, 1998, mais elle s'en diferencie par caractères précisés dans le texte.
