Bourgoinrana beondrokaensis Le Cesne & Soulier-Perkins sp. nov. Figures 8 , 9

Diagnosis.

Uniformly coloured brownish with smokey yellowish tegmina compared to the similar B. sandrangatensis which has a red head, thorax and base of tegmina. It also differs from this species by the length of its subgenital plates, 1.18 times longer than its pygofer height compared to 1.48 for B. sandrangatensis .

Distribution.

Mount Beondroka in the natural reserve of Marojejy, Madagascar (Fig. 9E ).

Description.

Total length of male holotype 7.9 mm (tegmina included), paratypes 8.4 and 8.6 mm. Flattened ventro-dorsally. Head in dorsal view, 1.6 times wider between eyes than long in midline, anterior and posterior margins gently and regularly curved. Ocelli very close to each other with distance between eye and ocellus 9 times greater than between ocelli, located close to head posterior margin. Pronotum slightly convex, 1.8 times wider than long in midline, posterior margin wave-shaped, concave in middle. Tegmina 3.8 times longer than wide, M and CuA with a common stem at base and forking around 1/3 of tegmen length, ScP+ R (+MA) forking after mid-length of tegmen, M and CuA both forking in apical third of tegmen. Metatibia bearing 1 lateral spine at 2/3 of its length.

Description of the male terminalia

(Fig. 9A-D ). Pygofer height 1.6 mm (Fig. 9A ) in lateral view, dorsal margin almost straight, posterior margin almost straight 2/3 of its dorsal length then curving strongly anteriorly before having a final straight section, ventral margin straight and shorter than dorsal margin, anterior margin S-shaped. Subgenital plates 1.18 longer than pygofer height, gently and regularly curving dorsally with a rounded apex pointing dorso-posteriorly, thickness gradually diminishing from base to apex with a slight constriction before apex. Parameres in lateral view with a small hump in the middle of dorsal margin ending in a narrow elongate finger-shape apex slightly curved inward (Fig. 9C, D ), ventral margin ending in a finger-shape apex shorter and less narrow than dorsal one; in dorsal view, internal margin cut out in two small extension facing each other (Fig. 9C ). Lateral plates present with dorsal margin straight, making a rounded acute angle with the postero-ventral margin. Aedeagus long, shaped as a circumvented tube with a thumb-shaped extension on its dorsal margin, oriented dorso-anteriorly, small constriction before thumb extension; apical part bifid, prolonging ventral margin a lateral toothed extension folding posteriorly with apex pointing antero-ventrally and prolonging dorsal margin a thin ending in a lanceolate shape pointing anteriorly (Fig. 9B ).

Colouration.

Generally yellowish brown, head darker between eyes along posterior margin, pedicel of antennae dark brown. Tegmina smokey yellow and translucent. Abdomen red and legs yellowish with darker tarsal segments, lateral metatibial spine black (Fig. 8 ).

Etymology.

The species is named after the type locality, Beondroka.
