Two new species of Heterolepismatinae (Zygentoma: Lepismatidae) from Far North Queensland

The Australian silverfish fauna is still poorly known, requiring more extensive field surveys and descriptions, preferably supported by molecular data. Here two new species of Silvestrisma Molero-Baltanás et al., 2025 (a genus recently split from Heterolepisma Escherich, 1905) are described from Far North Queensland, along with molecular data (COI, 28S) and compared to the closest Australian species S. howense (Womersley, 1942) and S. cooloola (Smith et al., 2019) as well as H. bisetosum (Carpenter, 1916) which is reported from the Seychelles and Somalia. Heterolepisma bisetosum is transferred to Silvestrisma based on its close similarity to this group of Australian species.
