Remarks

The species is known from a single female and the key to the genera proposed by Fennah (1964) leads to the genus Platybrachys Stål, 1859 . It is quite similar to P. leucostigma (Walker, 1851) (illustrations of the latter species available in Hacker 1924: fig. 14) by showing an apical white border on the posterior wings and numerous elongate cells in the costal area. The species is here transferred to Platybrachys, although it is obvious that a complete revision of the genus will be necessary (Constant 2008a).
