45 (20) - Pages 601-634Two important collections of Tetrigidae Rambur, 1838 containing more than 1000 individuals from French Guiana were consulted and revised in order to complete the knowledge of this group in this area. Given the large number of specimens to be treated, the analyses focussed in a first time on two subfamilies, Batrachideinae Bolívar, 1887 and Lophotettiginae Hancock, 1909, representing 489 individuals of which 456 were identified to species level. The results show the presence of 14 taxa, of which 11 are new to the department and four are new to science and described in this article: Paurotarsus pennatulus n. sp., Scaria guyanensis Doucet & Itrac-Bruneau, n. sp., Scaria macromaculata Doucet & Itrac-Bruneau, n. sp. and Scaria madeleinae n. sp. In addition, the female of Phelene maroon Cadena-Castañeda & Tumbrinck, 2021 and the male of Tettigidea pulchella Rehn, 1904, unknown until now, are described thanks to this material. As a result of these numerous contributions, a new identification key for the two studied subfamilies is proposed.
