Hemp, C; Voje, K L; Heller, K-G; Hemp, A: Biogeography, phylogeny and acoustics of the flightless bush-crickets of the East African genus Monticolaria Sjöstedt, 1909, with the description of a new species (Orthoptera: Phaneropterinae)., Zoological Journal of the Linnean Society, 156(3), 494-506 (2009)
Two species currently belong to the genus Monticolaria Sjöstedt, 1909, both of them restricted to submontane and montane forest, forest edge and clearings. In this study a new Monticolaria species is described which inhabits montane forest edge and forest clearings on Mt. Hanang and the Nou Forest reserve (Manyara escarpment) in north-western Tanzania. The first description of the female of Monticolaria kilimandjarica is also provided and a key for the genus is presented. Segments of the mitochondrial gene cytochrome oxidase subunit I (COI) were sequenced to infer phylogeographic patterns. These analyses confirm the genus as a monophyletic group. The calling song and data on the morphology of the stridulatory file of M. kilimandjarica are presented. The evolutionary history of Monticolaria is discussed in light of biogeographical, ecological and morphological data.
