Spe- cies diversity in French Guiana is similar to neighboring countries and a few additional species will probably be found.

RÉSUMÉ Liste commentée des Dermaptera (Insecta) de Guyane. Nous présentons la première liste des dermaptères de Guyane, mettant ainsi à jour les travaux anté- rieurs. Cette liste comprend 49 espèces, appartenant à cinq familles : Pygidicranidae Verhoeff, 1902, Forficulidae Stephens, 1829, Labiduridae Verhoeff, 1902, Spongiphoridae Verhoeff, 1902, Aniso- labididae Verhoeff, 1902. Vingt-quatre espèces sont mentionnées de Guyane pour la première fois. Cinq espèces ne sont citées que sur la base de données bibliographiques. Trois erreurs d’identification ou de répartition antérieures sont corrigées. La diversité spécifique de la Guyane est similaire à celle des pays voisins et quelques autres espèces seront probablement trouvées. Quelques espèces rarement collectées ont été trouvées, telles que Cosmogerax araguensis (Brindle 1974), Cosmogerax doesburgi MOTS CLÉS Guyane, Brindle 1982, Sarcinatrix quadrimaculata Brindle 1971, Doru unicolor Brindle 1971, Purex surina- Dermaptera, mensis Brindle 1971, Spongiphora buprestoides (Kirby 1891).
