| Comment | Venomous! For synonymy and references see VOGEL, DAVID & PAUWELS 2004. This paper was published 15 Nov 2004 and thus T. nebularis has priority over Popeia inornata, which was published on 13 December 2004. Habitat: fully arboreal (Harrington et al. 2018). |
| Etymology | Named after the Latin adjective nebularis, meaning “from the clouds”, in allusion to the cloudy montane rainforests, or cloud forests, inhabited by this species. Etymology (P. inornata): The specific epithet inornata is an adjective in the feminine singular gender. The scientific name of the new species alludes to the fact that adult males of P. inornata lack ornamentation by a distinctive orange to brick red ventrolateral stripe, which is typically present in adult males of sexually dimorphic members of the genus Popeia, and that both sexes show reduction of the white lateral stripe. |
