St Elie, Foret Yiyi; Guyane Française, Th Rosant; Rosant Th., N ° 4000 [coll. TR, No. 4000]. Etymology. This new species is dedicated to Alex Cahurel who collected the holotype, and in order to acknowledge his great efforts in collecting many Phasmatodea in French Guiana. Differentiation. The distinctive yellow to orange colour of the anal fan of the alae readily distinguishes D. cahureli n. sp. from all other species of the genus. In addition, males are distinguished by having the posterior margin of the poculum slightly pointed medially. Description: ♀ (Fig. 42). Typical size and body shape for the genus. Length of body 47.7–58.0 mm. General colour of body mid brown to dark chestnut brown with some pale granules on head and thorax. Ventral side brownish orange, in one PT with a distinct longitudinal black line on entire thorax and abdomen, less pronounced in the other ♀ PT. Head with several rows of tiny yellowish granules. Antennae dark brown with indistinct orange an- nulations at the apical end of the antennomeres. Eyes chestnut brown. Pro- and mesonotum covered with numerous small, yellowish to orange granules. Mesopleurae bearing strongly deflexed, parallel sided appendages with margins densely covered with long setae. Tegmina mid brown to chestnut brown with indistinct drab orange mottling. Costal area of alae yellow to orange in basal third and of same colour as tegmina in the apical two thirds. Anal area of alae dark yellowish to orange translucent, running into brownish translucent along the margins. Posterior margin of subgenital plate rounded. Legs chestnut brown, speckled with drab orange; knees black; ventral side of mid- and hind legs dark orange to greenish brown. Mesofemora bearing three small spines on ventral side. Measurements PT [mm]: Body 47.7–55.0, pronotum 3.2–3.5, mesonotum 4.4–5.2, metanotum 3.0–3.6, median segment 3.4–4.1, tegmina 16.2–16.9, alae 31.0–33.4, profemora 7.6–8.7, mesofemora 5.2–5.7, metafemora 10.4–12.5, antennae 25.5. ♂ (Figs. 43–44). Length of body 37.0– 38.9 mm. Similar to ♀, but more slender and smaller. Cerci as long as anal segment. Poculum drab orange brown, small and flat, reaching posterior margin of tergum IX; posterior margin rounded. Measurements HT [mm]: Body 37.5, pronotum 2.3, mesonotum 4.5, metanotum 4.1, median segment 2.7, tegmina 11.2, alae 22.8, profemora 7.5, mesofemora 4.6, metafemora 9.1, protibia 5.1, mesotibia 4.1, metatibia 7.7, head 2.3, antennae>21.5. Measurements PT [mm]: Body 37.0–38.9, pronotum 2.4–2.7, mesonotum 3.2–3.8, metanotum 2.9–3.4, median segment 2.7–3.0, tegmina 11.7–12.0, alae 23.6–23.9, profemora 6.5–7.5, mesofemora 4.5–4.6, metafemora 8.7–9.9, antennae>21.0.
