Melanotus dichrous
Melanotus dichrous is a click beetle species in the family Elateridae, first described by Erichson in 1841 under the basionym Cratonychus dichrous. The species is known from the Azores archipelago in the North Atlantic, with records from five islands: Faial, Flores, Graciosa, Pico, and São Jorge. As a member of the genus Melanotus, it shares the characteristic click beetle morphology including an elongated body form and the prosternal process that enables the defensive "clicking" mechanism.
Mycetaea subterranea
Mycetaea subterranea is a small beetle species in the family Mycetaeidae, historically classified in Endomychidae. It is distributed across the Azores archipelago, with records from Faial, Flores, and São Miguel islands. The species was originally described by Fabricius in 1801 as Dermestes subterranea. Limited biological information is available for this insular species.
Peripsocus milleri
Peripsocus milleri is a species of barklouse in the family Peripsocidae, characterized by brown coloration. The species has been recorded across multiple regions including Great Britain, Ireland, continental Europe, and several Atlantic island groups. It is associated with oak trees as a feeding substrate.
Xantholinus longiventris
Long-bellied Rove Beetle
Xantholinus longiventris is a species of rove beetle in the family Staphylinidae, first described by Heer in 1839. It is known from the Azores archipelago, with records from five islands: Faial, Flores, Graciosa, Pico, and São Jorge. The species is recognized by iNaturalist as the Long-bellied Rove Beetle and has accumulated over 200 observations, suggesting it is relatively well-documented for an island endemic. Its taxonomic status shows some discrepancy between sources, with Catalogue of Life listing it as a synonym while GBIF treats it as accepted.
