Supplements to the knowledge of Phantasca Redtenbacher, 1906, with the descriptions of four new species from French Guiana (Phasmatodea, Diapheromeridae, Diapheromerinae)

Abstract

Four new species of the genus Phantasca Redtenbacher, 1906 (Phantasca bulbosa n. sp., P. arlequina n. sp., P. kawensis n. sp. and P. margaritae n. sp.) from French Guiana are described and illustrated. The female of P. femorata Hennemann, Conle, Bellanger, Lelong & Jourdan, 2018, is re-described due to subsequent discovery of an adult specimen, and the previously unknown egg is described for the first time. The male of P. ruboligata Hennemann et al., 2018, is re-described with the holotype illustrated to rule out confusion with the male of P. margaritae n. sp. A barcoding study based on COI gene of eight species of Phantasca is presented and supports their inclusion within the genus.
