The longicorn beetle tribe Cerambycini Latreille, 1802 (Coleoptera: Cerambycidae: Cerambycinae) in the fauna of Asia. 8. New or little-known taxa from India, Indochina and Sumatra, with notes on the genus Carinolesthes Vitali, Gouverneur et Chemin, 2017

A brief review of the genus Carinolesthes Vitali, Gouverneur et Chemin, 2017, as well as a key to its species are given. A new species of this genus, C. dembickyi sp. n., is described from the Northeastern India. The need to clarify the generic attribution of C. ningshanensis (Chiang, 1981) is justified. Two new species of the genus Diorthus Gahan, 1891, both from Southern India, D. dembickyi sp. n. and D. aurosetosus sp. n., similar to another South Indian species D. sericeus Gardner, 1939, are described. These three species form a peculiar group which illuminates a very strong morphological similarity between the genera Diorthus and Lamellocerambyx Pic, 1923. At the same time, some recently revealed stable differences between these genera are given. A new species, Zatrephus sumatranus sp. n., is described from Sumatra. The previously unknown female of Elydnus barclayi Miroshnikov, 2017 and male of Pachydissus patricius Holzschuh, 1991 are also described, while the latter species is being recorded from Western Malaysia for the first time. Numerous and detailed colour pictures of the species studied, including their type specimens, are provided.
