Abstract The present paper describes 16 new species and one new genus from French Guiana and numerous taxonomic changes are proposed prior to the publication of a comprehensive guide to the Phasmatodea of French Guiana. The following 16 new species are described and illustrated: Phanocles procerus n. sp., Phanocloidea lobulatipes n. sp., Cladomorphus guianensis n. sp., Hirtuleius gracilis n. sp., Parastratocles rosanti n. sp., Parastratocles fuscomarginatus n. sp., Paraprisopus apterus n. sp., Paraprisopus multicolorus n. sp., Agrostia longicerca n. sp., Isagoras similis n. sp., Paragrostia brulei n. sp., Prexaspes globosicaput n. sp., Prexaspes guianensis n. sp., Dinelytron cahureli n. sp., Prisopus clarus n. sp. and Prisopus conocephalus n. sp.. The new genus Paragrostia n. gen. is established for the newly described Paragrostia brulei n. sp. and Paragrostia flavimaculata (Heleodoro, Mendes & Rafael, 2017) n. comb. the latter of which is here transferred from Agrostia Redtenbacher, 1906.
