The darkling beetle genus Hypogena Dejean, 1834 (Tenebrionidae: Tenebrioninae) is revised. Hypogena is entirely composed of dorsoventrally flattened species that live subcortically in dead trees. This genus is generally identified by male specific characters, particularly the presence of cephalic horns. Hypogena is currently placed within the tribe Triboliini Gistel, 1848. However, several previously overlooked morphological characters call into question its placement within the tribe. A morphological matrix of 94 external adult characters was assembled to examine species relationships and boundaries. The resulting phylogeny is presented. Thirteen Hypogena species were previously recognized as valid, including Hypogena marginalis Doyen & Poinar from Dominican amber. Four previously unidentified species are described in this study: Hypogena akuma sp. nov. (Brazil), Hypogena cryptica sp. nov. (Mexico), Hypogena hirsuta sp. nov. (Ecuador), and Hypogena reburra sp. nov. (Colombia). Lectotypes are designated for Hypogena depressa (Champion, 1886), Hypogena dejeani (Champion, 1886), Hypogena canaliculata (Champion, 1886), and Hypogena vacca (Fabricius, 1801). A neotype is designated for Tenebrio biimpressus (Latreille, 1833) (type species of Hypogena, synonymized under Hypogena brasilica (Perty)) in order to maintain stability within the genus.

Aim. In this work, we aimed to study the distribution and habitat of rare Caucasian tenebrionid beetle Hedyphanes nycterinoides, as well as to identify reasons for the population re‐ duction and to develop a basis for its protection.Methods. Materials from the largest collection of the Zoological Institute RAS (St Petersburg) along with the authors’ fieldwork data were used for mapping the past and current distribution of the species, as well as for studying its habitat and possible trophic relations.Results. The taxonomic history of H. nycterinoides is complicated due to the loss of the type material. This taxon is currently interpreted as a separate species. H. nycterinoides is distributed across Piedmont Dagestan and Intermountain Dagestan (Russia); however, all known specimens were collected only in the 19th‐20th centuries (the last record is dated 1984). The population of H. nycterinoides from Intermountain Dagestan is likely to have died out due to the filling of the Irganay reservoir in 2008. Only one present‐day population from the arid Rubas valley in Southern Dagestan is known. The species inhabits saline soils (solonetz, solonchak) and feeds on saltworts. It is active in April–May in the evening or in the daytime provided it is cloudy.Conclusions. We recommend that H. nycterinoides be included in the list of threatened species of Dagestan as an indicator of the state of halophytic plant communities from the hilly landscapes of the Eastern Caucasus. The main factors of the contemporary population reduction include overgrazing and filling of reservoirs.

The generic name Heliopathes Opresko, 2003 (see also Opresko 2005) proposed for an antipatharian coral (Cnidaria: Anthozoa: Antipatharia) of the family Cladopathidae, subfamily Hexapathinae (Opresko, 2003), is preoccupied by the darkling beetle genus Heliopathes (Coleoptera, Tenebrionidae), proposed by Mulsant (1854). Therefore the substitute name Heteropathes is proposed for the antipatharian.

The description of an extinct species of Metaclisa Jacquelin du Val, 1861 (Tenebrionidae) is presented. This genus and the tribe Metaclisini are recorded as fossils for the first time, from Eocene Baltic amber. The new species Metaclisa ottoi sp. nov. belongs to the subgenus Trichometaclisa subgen. nov. and differs from all other Metaclisini in possessing short, fine recumbent setation on the pronotum and elytra; in addition, the prosternal process in Metaclisa ottoi sp. nov. is roundly bent down and weakly projected behind the procoxae, which differs from extant species.
