Is the Existence of Two Lineages for Hamadryas glauconome (Lepidoptera: Nymphalidae) True? Molecular and Ecological Evidence

open access: yesDiversity, 2023
The genus Hamadryas has a neotropical distribution. In 1983, the subspecies H. glauconome grisea from Mexico was recognized with subtle and subjective differences in color, size and distribution and limited to the northwest.

Freshwater fishes of the Waterberg aquatic ecoregion, South Africa: Diversity, taxonomic conflicts and conservation concerns

open access: yesJournal of Fish Biology, EarlyView.
Abstract Southern Africa is a region denoted by both high levels of fish diversity, some of it cryptic and unrecognised by current taxonomy, and severely threatened freshwater ecosystems. The Waterberg, a key aquatic ecoregion of the greater Limpopo River basin in South Africa, represents an area with high terrestrial conservation value but is lacking ...

Integrative taxonomy reveals four new species of the armoured catfish genus Pareiorhina (Siluriformes: Loricariidae) from the upper Paraná River basin, Brazil

open access: yesJournal of Fish Biology, EarlyView.
Abstract Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...

A new endemic pearl cichlid of the ‘Geophagus’ brasiliensis (Cichliformes: Cichlidae) species group from the Piranga River, upper Doce River basin, southeastern Brazil

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of pearl cichlid of the ‘Geophagus’ brasiliensis species group, endemic to the Piranga River, a major tributary of the upper Doce River basin in the state of Minas Gerais, southeastern Brazil, is herein described. The new species is delimited using an integrative approach, with molecular‐based species delimitation methods coupled

A new, conspicuously pigmented Pyrrhulina (Teleostei: Characiformes: Lebiasinidae) from the Río Tigre, Loreto, Peru

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of Pyrrhulina is described based on morphological and molecular evidence. Pyrrhulina punctata is distinguished from all congeners by the presence of a series of 7 to 16 irregular blotches of dark pigmentation on the flanks, equally marked in juveniles and adult specimens, the presence of 26–28 lateral‐line scales, 17–21 maxillary

Benthoplanidae, a new family of benthic ctenophores (Platyctenida), based on morphological and genetic data

open access: yesJournal of Systematics and Evolution, EarlyView.
The benthic ctenophore Benthoplana meteoris (adults left and bottom, planktonic juveniles to the top right), type species for the genus, which in turn is type for the newly erected family: Benthoplanidae (Ctenophora, Platyctenida). Abstract We present a phylogenetic analysis of benthic ctenophores of the order Platyctenida, sampling all but one genus ...

Filter feeders living on suspension feeders: New insights into the lifestyle and distribution of Arcturidae Dana, 1849 (Crustacea: Isopoda) around Iceland

open access: yesMarine Ecology, EarlyView.
Abstract The focus of the present study was on arcturid isopods occurring in the subarctic region around Iceland. Data from two decades of sampling with an epibenthic sledge (EBS) during numerous expeditions of the BIOICE (Benthic Invertebrates of Icelandic Waters; 1992–2004) and IceAGE (Icelandic marine Animals: Genetics and Ecology; 2011—ongoing ...

Phylogenetic species delimitation for crayfishes of the genus Pacifastacus [PDF]

open access: yesPeerJ, 2016
Molecular genetic approaches are playing an increasing role in conservation science by identifying biodiversity that may not be evident by morphology-based taxonomy and systematics.

Profundum solomoni (Amphipoda: Uristidae) Exhibits a Disjunct Geographic Distribution at Hadal Depths Across the San Cristobal Trench, Santa Cruz Trench and Nova Canton Trough

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Hadal environments (> 6000 m ocean depths) are often viewed as isolated locations with high species endemism due to limited dispersal. However, molecular studies continue to reveal greater complexity that questions historical perceptions. Recent population genetic studies focused on scavenging amphipods have identified broadly distributed ...

DNA barcoding for community ecology--how to tackle a hyperdiverse, mostly undescribed Melanesian fauna. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Trigonopterus weevils are widely distributed throughout Melanesia and hyperdiverse in New Guinea. They are a dominant feature in natural forests, with narrow altitudinal zonation.
