description: Eurycoplangiodes sanghaensis Massa, new sp. Figs. 21–26a
Material examined. CAR. Dzanga-Sangha SR, transit Camp 3, near Sangha river, 25–26.X.2008 (light), P. Annoyer (1♂ holotype) (BMPC).
Diagnosis. E. sanghaensis n. sp. is characterized by the shape of the eye not much elongated as in Eurycorypha, more similar to that of Plangiodes, but more prominent. Lateral carinae of forehead are stout, lateral carinae are present on pronotum, dorsal margin of fore tibiae is rounded, mirror of right tegmen is absent.
1 Plangiodes does not share characters with the genus Plangia Stål, 1873, as Chopard (1954) reported at the beginning of the description.
Description. Male (Fig. 21). General habitus and colour. Antennae greenish, forehead carinae yellow, body green, tegmina green (Figs. 21, 23, 24). Abdomen yellow, legs yellow-green, tarsi blackish. Head and antennae. Fastigium of vertex not contiguous with fastigium of frons, scarcely wider than first antennal segment. Eyes a little elliptical, prominent, face smooth with lateral stout carinae below the eyes (Figs. 23–24). Thorax. Pronotum as long as high, with lateral carinae, surface shiny with a well-developed humeral excision on the lateral lobes (Figs. 21, 24). Anterior margin of pronotum incurved, posterior margin rounded, pronotum lobes widely rounded. Tegmina with a net of veinlets; anterior margin of tegmina rounded. Stridulatory area marked, posteriorly protruding, right tegmina with a wide posterior protruding base and mirror lacking (Fig. 22), stridulatory file short, ca. 0.4 mm long, consisting of about 50 sinuous teeth, central higher than external ones (Fig. 25). Legs. Short, fore coxae armed with a fine spine, open tympana on inner and on outer fore tibiae, that are rounded dorsally. Ventral inner margin of fore femora armed with 3 spines, ventral outer margin of mid femora armed with 3 spines, ventral outer and inner margins of hind femora armed with 3–4 spines, genicular lobes of hind femora armed with 1 spine on inner and outer margins. Fore tibiae ventrally armed with 6 spines + 1 apical spur on outer and inner margins, mid tibiae armed with 7 ventral spines + 1 spur on outer and inner margins, hind tibiae with many spines on ventral and dorsal margins + 3 apical spurs on each side. Abdomen. Last abdominal tergite inflated laterally, supragenital plate long, cerci stout at the base, with a robust apical inward spine (Fig. 26). Subgenital plate much longer than wide, ending with two tips, styli absent (Fig. 26a).
Measurements (mm). Male. Body length: 19.0; length of pronotum: 3.6; height of pronotum: 3.6; length of fore femora: 3.4; length of mid femora: 5.7; length of hind femora: 11.1; length of tegmina: 24.3; width of tegmina: 6.0.
Etymology. After the Sangha river in the Dzanga-Sangha SR (CAR).
Distribution. At present E. sanghaensis n. sp. is known only from Dzanga-Sangha SR.
