Summary

Shivapuri Nagarjun National Park (SNNP) is a protected land spanning an area of 159 km2 in the heart of central Nepal. This area has never been systematically explored in search of the family Tetrigidae (Orthoptera). In this paper, we report 11 species from SNNP, of which five are new to science: Aryalidonta rochaki n. sp., Skejotettix mahendrai n. sp., Skejotettix mahajodi n. sp., Lamellitettigodes jhalakmani n. sp., and Hebarditettix sanduki n. sp. Due to new combinations, the genus Aryalidonta Subedi & Kasalo, 2023 has three additional species, Aryalidonta ridleyi (Günther, 1938) n. comb., A. dohertyi (Hancock, 1915) n. comb. and A. pallida (Hancock, 1915) n. comb., all of which were previously assigned to Eucriotettix Hebard, 1930. Brief notes on compositions and diagnoses of genera Lamellitettigodes Günther, 1939 and Skejotettix Subedi, 2022 are provided, inviting further research. The generic assignment of Pseudoparatettix incertus Ingrisch, 2001a called into question. An identification key to all the tetrigids of SNNP is provided.

Résumé

Tetrigidae (Orthoptera) du Parc national de Shivapuri Nagarjun, au Népal. Le parc national de Shivapuri Nagarjun est une aire protégée s'étendant sur une superficie de 159 km² au centre du Népal. Cette zone n'a jamais été explorée systématiquement à la recherche de spécimens de la famille des Tetrigidae (Orthoptera). Dans cet article, nous signalons 11 espèces de ce parc national, dont cinq sont nouvelles pour la science : Aryalidonta rochaki n. sp., Skejotettix mahendrai n. sp., Skejotettix mahajodi n. sp., Lamellitettigodes jhalakmani n. sp., et Hebarditettix sanduki n. sp. Du fait de nouvelles combinaisons, le genre Aryalidonta Subedi & Kasalo, 2023 compte trois espèces supplémentaires, A. ridleyi (Günther, 1938) n. comb., A. dohertyi (Hancock, 1915) n. comb. et A. pallida (Hancock, 1915) n. comb., qui étaient toutes précédemment attribuées à Eucriotettix Hebard, 1930. De brèves notes sur la composition et les caractères diagnostiques des genres Lamellitettigodes Günther, 1939 et Skejotettix Subedi, 2022 sont fournies, invitant à des recherches plus approfondies. L'affectation générique de Pseudoparatettix incertus Ingrisch, Citation2001a est remise en question. Une clé d'identification de tous les tétrigides du parc national est fournie.
