|Hemp, C; Hemp, A; Wägele, W: Description of a new species of Parasphena Bolivar, 1884 (Orthoptera: Pyrgomorphidae) from northwestern Tanzania and new data on the biogeography, coenology, habitat and morphology of the genus, Journal of Orthoptera Research, 18(1), 113-119 (2009)|
A new species of Parasphena is described from southwestern Tanzania, occurring in the montane zone of the third highest mountain, Mt Hanang. Morphological details are given for P. hanangensis n. sp. and for species on the northern branch of the Eastern Arc mountains, Mt Kilimanjaro and the Kenyan highlands, morphologically related to this new species. A coenological comparison is made between several high mountains of East Africa; patterns of present-day distribution — the result of climatic fluctuations of the past — are discussed. Information on distribution, habitat and altitudinal ranges are given for all species of the genus Parasphena.
