On the identity of Scaphidium grande, with resurrection of S. inimpressum and S. melanopus and description of two new species (Coleoptera: Staphylinidae: Scaphidiinae)
Year: 2025
Type: paratext
Abstract: Scaphidium grande Gestro, 1879, assumed to be widely distributed in Asia, has been misidentified. The range of this species is likely restricted to Borneo. Scaphidium grande is distinguished from allied species by the male genital characters, notably by the shape of the median lobe. Scaphidium grande var. inimpressum Pic, 1920 and S. grande var. melanopus (Achard, 1924), placed in synonymy by Löbl (1992, 2018), are resurrected as valid species. The lectotype is designated for Scaphidiolum grande var. melanopus Achard, 1924. Similar and obviously related species, Scaphidium metafasciatum sp. nov. from Taiwan and Scaphidium grandior sp. nov. from Thailand, are described.
