Comment | Type species: Tropidonotus vibakari BOIE 1826: 207 is the type species of the genus Hebius Thompson 1913. Synonymy: Gao et al. 2024 synonymized Hebius vibakari ruthveni (VAN DENBURGH 1923) with the nominate subspecies, H. vibakari. Key: Zhou et al. 2019 provide a key to the Hebius species of China. Comparisons: for a list of characters across the genus Hebius see Ma et al. 2023: 219 (Table 4) |
Etymology | The genus name Hebius is derived from the Japanese noun “Hebi" (which means snake in Japanese), and the -us ending indicates it is masculine (David et al. 2021). Guo et al. (2014: 438) also stated that Hebius was masculine but these authors variously treated it as neutral (for example: Hebius modestum, p. 437 & 438) or feminine (Hebius modesta, p. 428). |
