New crickets (Orthoptera: Gryllidae) from the mountain forests of South Africa

A new material on the genera Prolandreva Gorochov, 2005 (Landrevinae: Prolandrevini), Stalacris Desutter-Grandcolas, 2013 (Phalangopsinae: Phalangopsini) and Parametrypa Brunner-Wattenwyl, 1873 (Podoscirtinae: Podoscirtini) from the mountain forests of the Limpopo Province (South Africa) is considered. The following new taxa are described: the subgenus Urolandreva subgen. nov. (inside the first genus); Prolandreva (U.) irisovi sp. nov. (Wolkberg Mts); P. (U.) spinula sp. nov. (Soutpansberg Mts); S. oskolskyi sp. nov. (Wolkberg Mts); Parametrypa dentata curvitibia subsp. nov. (Soutpansberg Mts). A previously unknown male of the nominotypical subspecies of the latter species, P. d. dentata Gorochov, 2021, is also described. Some data on the ecological characteristics of these taxa and on the historic geography of South Africa and adjacent territories are briefly presented. These data allow us to propose a hypothesis that the distribution of the above-mentioned genera along the coast of the Indian Ocean from Eastern Cape to Swaziland and in the isolated mountain forests of the Limpopo Province, located rather far from this coast, could have appeared as a result of partial aridization of the former large forest area, which occupied a significant territory of South Africa (and some nearest countries) and had a similar endemic fauna of crickets.
