UITOTO: a software for generating molecular diagnoses for species descriptions

Cladistics, Volume 42, Issue 2, Page 193-205, April 2026.
Abstract Millions of species remain undescribed, and each eventually will require a species description with a diagnosis. Yet, we lack software that can derive state‐specific and contrastive molecular diagnoses and allows the user to validate them based on all available sequences for the taxon under study. Here we introduce UITOTO, which addresses this

Species delimitation of neotropical Characins (Stevardiinae): Implications for taxonomy of complex groups.

PLoS ONE, 2019
Accurate species delimitation is crucial for studies of phylogeny, phylogeography, ecology, conservation and biogeography. The limits of species and genera in the Characidae family are controversial due to its uncertain phylogenetic relationships, high ...

Diversity and Potential Endemism of New Zealand Freshwater Rotifers Revealed Using Mitochondrial DNA Barcodes

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
Rotifers perform key functions in aquatic food webs and respond to environmental changes, thus providing sensitive indicators of water quality. However, rotifers are small, highly diverse, and difficult to identify for those lacking expertise. Monogononta are the largest taxonomic class of rotifers with over 1500 species described globally, and around ...

Taxonomic investigation of Abrothallus (Abrothallales, Ascomycota) species associated with lichen genera Ramalina and Bryoria, including the description of a new species

Nordic Journal of Botany, Volume 2026, Issue 2, February 2026.
The obligately lichenicolous genus Abrothallus consists of approximately 50 species, almost all of which are associated with lichens having foliose, fruticose, or pendulous thalli. This paper focuses on species that grow on strap lichens (Ramalina) providing new insights into their phylogenetic relationships and distribution.

Establishment of six new Rhabdoblatta species (Blattodea, Blaberidae, Epilamprinae) from China [PDF]

ZooKeys, 2019
This study examined 504 Rhabdoblatta specimens sampled from China, of which, 86 Rhabdoblatta specimens were used for COI sequencing. A phylogenetic analysis using the ML method and MOTUs estimations by ABGD and GMYC based on COI sequences was performed ...

How many cows are in the desert? Molecular phylogeny and species delimitation of the genus Gyriosomus (Coleoptera: Tenebrionidae: Pimeliinae) from the Atacama Desert

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
The newly systematic rearrangement of Gyriosomus recognizes 9 clades, validates 21 taxonomical species and suggests 12 synonyms and 12 species candidates. Three taxonomical species were not evaluated. Polymorphisms, convergences and crypsis have been detected, and therefore morphology‐based taxonomy should be approached with caution. Ecological drivers

Hidden Diversity of Cave Millipedes From Mainland Southeast Asia Revealed by Species Delimitation and Phylogenetic Analysis, With a Description of a New Genus (Spirostreptida: Cambalopsidae)

Journal of Zoological Systematics and Evolutionary Research, Volume 2026, Issue 1, 2026.
Southeast Asia’s karst landscapes host a remarkable yet understudied diversity of cave‐dwelling fauna, where morphological conservatism often masks true species boundaries. Using an integrative taxonomic framework, we investigated the systematics of the millipede family Cambalopsidae Cook, 1895 inhabiting caves across Thailand, Laos, Myanmar, and ...

Ecological and molecular diversity of Eulachnini aphids (Hemiptera: Aphididae: Lachninae) on coniferous plants in Lithuania

European Journal of Entomology, 2020
Based on research carried out from 2016 to 2018 there are twenty-six species of aphids of the tribe Eulachnini in Lithuania. Seventeen are members of the subgenus Cinara of the genus Cinara, three of the subgenus Cupressobium and two of the subgenus ...

Genetic and morphological analyses indicate that the Australian endemic scorpion Urodacus yaschenkoi (Scorpiones: Urodacidae) is a species complex [PDF]

PeerJ, 2017
Background Australian scorpions have received far less attention from researchers than their overseas counterparts. Here we provide the first insight into the molecular variation and evolutionary history of the endemic Australian scorpion Urodacus ...

Integrative taxonomy of Metrichia Ross (Trichoptera: Hydroptilidae: Ochrotrichiinae) microcaddisflies from Brazil: descriptions of twenty new species [PDF]

PeerJ, 2016
Metrichia is assigned to the Ochrotrichiinae, a group of almost exclusively Neotropical microcaddisflies. Metrichia comprises over 100 described species and, despite its diversity, only one species has been described from Brazil so far. In this paper, we
