Three species of the africana-group of the Genus Gryllotalpa (Orthoptera: Gryllotalpidae) were recorded from Cameroon during an investigation from March 2016 to March 2018: Gryllotalpa africana Beauvois from Buea and Tombel, and two new species, Gryllotalpa tombelensis Simeu-Noutchom and Kekeunou sp. nov. from Tombel and Gryllotalpa babetensis Simeu-Noutchom and Kekeunou sp. nov. from Babété. Gryllotalpa tombelensis is characterised by short wing morphology, vestigial hind wings, small phallic complex, short internal processes, and dorsoventrally flattened body. Gryllotalpa babetensis is distinct from other species of the africana-group by the mesoscutum being more exposed between the pronotum and the base of the fore wings, having a very large phallic complex, with very long internal processes of ectophallus (3 mm long).

Abstract

Three species of the africana-group of the Genus Gryllotalpa (Orthoptera: Gryllotalpidae) were recorded from Cameroon during an investigation from March 2016 to March 2018: Gryllotalpa africana Beauvois from Buea and Tombel, and two new species, Gryllotalpa tombelensis Simeu-Noutchom and Kekeunou sp. nov. from Tombel and Gryllotalpa babetensis Simeu-Noutchom and Kekeunou sp. nov. from Babété. Gryllotalpa tombelensis is characterised by short wing morphology, vestigial hind wings, small phallic complex, short internal processes, and dorsoventrally flattened body. Gryllotalpa babetensis is distinct from other species of the africana-group by the mesoscutum being more exposed between the pronotum and the base of the fore wings, having a very large phallic complex, with very long internal processes of ectophallus (3 mm long). Both new species were collected in crop fields, but which differ in their habitat characteristics, such as soil moisture, pH and granulometry.
