Taxonomy is the foundation of biology, providing the currency (species) for biological studies and the handle (epithet) to refer to them. The task at hand is urgent: a race against extinction as most species remain undescribed and expertise declines....
The field of taxonomy is undergoing a profound renaissance, driven by the integration of classic morphological descriptions with modern genomic, bioinformatic, and ecological tools [...]
The cyanobacterial genus Aliterella (Chroococcidiopsidales) comprises coccoid taxa with a broad geographic and ecological distribution, occurring in habitats ranging from polar environments to arid deserts and tropical regions. In this study, we desc...
Background: Although there is a compendium of species diversity for the Flora of North America, including the Fabaceae, many legume species were excluded. Therefore, this study fills this information gap and updates the systematics and nomenclature o...
Our communication summarizes the recent changes in the paraphyletic species Orthoflavivirus encephalitidis. The paraphyly arises due to louping-ill virus (LIV), which is genetically closer to the European subtype of tick-borne encephalitis virus (TBE...
The genieri species group of the Neotropical genus Deltochilum Eschscholtz, 1822 (subgenus D. Deltohyboma Lane, 1946) is studied. Based on the morphological analysis of 729 specimens, fourteen new species are described: D. cryptoporum sp. nov.,...

A field inventory in the Rio Chapecó drainage, southern Brazil, about 11,120 km2, revealed an unexpected diversity of endemic small fossorial catfishes, genus Cambeva, comprising 2 species recently described and 11 undescribed. They were found...
Compsemys is an enigmatic turtle first described over 160 years ago. Its taxonomic position has been uncertain, as many of the species placed in the genus have since been removed from it. For the last 30+ years, Compsemys victa has been the only reco...
Penicillium and Talaromyces are among the most diverse genera of filamentous fungi and play important ecological roles in soil ecosystems. Despite their ecological and biotechnological relevance, the diversity of these genera remains insufficiently d...
Troglonectes is an endemic cavefish genus of Nemacheilidae, mainly distributed in Guangxi and Guizhou, China. In April 2025, ten specimens of Troglonectes were collected from a subterranean stream of a Liujiang River tributary in Jinchengjiang Distri...
Paragryllina currently comprises more than 30 species of predominantly dendrophilous crickets, all previously recorded exclusively from tropical rainforests environments. Over the past three decades, the taxonomy of this subtribe has undergone succes...
The Macaronesian archipelagos harbor a highly endemic fauna of the flatid genus Cyphopterum Melichar, 1905, characterized by pronounced insular diversification. Despite approximately 80% of its species being unique to the region, the morphology and b...
Gymnodiptychus Herzenstein, 1892, a genus of the subfamily Schizopygopsinae, currently comprises three valid species: Gymnodiptychus dybowskii, Gymnodiptychus pachycheilus, and Gymnodiptychus integrigymnatus. Previous molecular phylogenetic studies h...
This study presents a cytogenetic and comparative analysis of three rare terrestrial orchid species from Thailand: Habenaria janellehayneana, H. rhodocheila, and Nervilia khaoyaica. Somatic chromosome numbers, karyotype structures, and chromosomal mo...
Macroevolutionary analysis evaluating structural monophyly as descent with modification allows recasting of taxa in terms of physics as evolutionary mechanics. There are four natural ranks, as generalized taxa: the species, genus, lineage, and metali...
Identification keys are important aspects of taxonomic research, but their quality varies substantially. I surveyed all the keys associated with the description of new non-insect animal genera that were available to me (through online and library res...
Two new species of the subfamily Lecithocerinae (Gelechioidea, Lecithoceridae); Notioseus liberianus Park & Karisch, sp. nov. and Lecithocera maruana Park & Karisch, sp. nov., are described from the Nimba Mountains, bordering Guinea and Liber...
Two new species of Lonchaeidae in the genus Lonchaea, namely Lonchaea desirade sp. nov. and Lonchaea minutissima sp. nov., are described from the island of Guadeloupe in the Lesser Antilles, an island group in the southern Caribbean Sea. The genitali...
Knowledge of the biology of the genus Vitis has undergone a profound transformation, evolving from the morphological descriptions of classical ampelography to the high-resolution analyses enabled by modern phylogenomics. This review explores the &ldq...
