This article is a part of the thematic issue “Our Planet Reviewed” 2015 large-scale biotic survey in Mitaraka, French Guiana

Two species of Eucocconotini Beier, 1960 were collected during the “Our Planet Revisited, Mitaraka 2015” survey in the Mitaraka Mountains belonging to Tumuc-Humac mountain chain in French Guiana: Gnathoclita vorax (Stoll, 1813) and Panoploscelis scudderi Beier, 1950. Calling songs of both species are described for the first time, as well as the mandibular and tegminal protest signals from P. scudderi males and females. The structures involved in these signals are described and illustrated. The peculiar acoustic and mate guarding behaviors of Gnathoclita vorax are described and illustrated. The synonymy of Panoploscelis scudderi Beier, 1950 and Panoploscelis angusticauda Beier 1950 n. syn. is discussed and proposed, based on specimens reared from samples collected in Mitaraka.
