A new species of the genus Diploderma Hallowell, 1861 from Qiaojia County, Zhaotong City, northeastern Yunnan Province, China, is described. Phylogenetically, the new species is placed within the D. splendidum complex and has genetic distances of 7.3% and 7.5% from D. splendidum (Barbour & Dunn, 1919) sensu stricto and D. daduense Cai, Liu & Chang, 2024, respectively, based on the ND2 gene sequences. Morphologically, the new species closely resembles D. splendidum sensu stricto and D. daduense, however, it can be distinguished from D. splendidum sensu stricto by having a larger body size in males and relatively shorter limbs, and can be differentiated from D. daduense by having a relatively narrower head in males and relatively shorter forelimbs in males. In addition, the new species differs from D. splendidum sensu stricto and D. daduense by having different colorations, especially in the absence of transverse stripes on the dorsal head. This study further revealed that D. splendidum sensu lato is a complex containing multiple species and that more research is needed to clarify the taxonomy of the complex.

Brevinasia gen. n., a new genus of edaphic weevils with 14 species from the South African provinces of Western Cape, Eastern Cape, KwaZulu-Natal, and Limpopo, is described. The genus is described and illustrated, its taxonomic placement is discussed, and a key to the species is given. The specimens are usually associated with leaf litter in forest habitats and were generally sampled by sifting forest soil. Its type species, B. brevicollis (Voss, 1974), is redescribed, and 13 new species are described: B. albonigra sp. n. (type locality: Hills east of Stilbaai); B. bulirschi sp. n. (type locality: Marloth Nature Reserve); B. inconspicua sp. n. (type locality: Robinson’s Pass); B. janaki sp. n. (type locality: Hawequas); B. leleupi sp. n. (type locality: Humansdorp); B. limpopoensis sp. n. (type locality: Kruger National Park); B. litoralis sp. n. (type locality: West Gouritsmond); B. longiseta sp. n.

The Brazilian Atlantic Forest, one the five main biodiversity hotspots in the world, still houses many organisms that are rare and unknown to science, mostly concentrated in mountain ranges. Herein, we describe a rare new species of Cambeva from the Rio Tietê drainage at the Serra da Mantiqueira, exhibiting a caudal fin color pattern comprising a light-yellowish–white bar posteriorly edged by a black pigmented area. A similar color pattern was described for C. castroi, C. diabola, and C. melanoptera, also endemic to the Rio Paraná basin, and considered evidence of close relationships among these three species. However, other morphological characteristics highly suggest that the new species is not closely related to C. castroi, C. diabola, and C. melanoptera). Herein, we perform a molecular phylogenetic analysis using two mitochondrial genes and one nuclear gene, including all species with that bicolored caudal pattern. The analysis strongly supports the new species as a member of the alpha-clade, and therefore as distantly related to those three species belonging to the beta-clade, indicating that this color pattern has homoplastically arisen in Cambeva. The data reported here reinforce the urgent need for field studies to better understand the different evolutionary patterns found in the genus, since an intense process of environmental degradation is in course.

(1) Background: Although Physaloptera retusa is one of the most widespread species infecting reptiles in the Americas, numerous taxonomic problems and little genetic data are associated with it. To clarify the taxonomy of this species, we used an integrative approach. (2) Methods: Physaloptera retusa-infecting Erythrolamprus typhlus (snake) from the Pantanal wetlands, Brazil, was morphologically and genetically characterised (18S and 28S rDNA; COI mtDNA) and compared with conspecific sequences available in GenBank, from parasites of Tupinambis teguixin (lizard), using species delimitation methods. Type specimens of P. liophis were re-evaluated given its morphological similarities with P. retusa. (3) Results: The morphology of the present specimens was equal to that of P. retusa, in which the only difference from P. liophis was the relative position of the vulva. Species delimitation methods were more accurate for the COI dataset; all of them (except ABGD) indicated interspecificity among P. retusa sequences. However, a lack of morphological data or voucher material, associated with the deposited sequences, prevented more assertive conclusions. (4) Conclusions: The present results highlight the importance of a clear association between genetic data and morphology of the isolation source, or at least its adequate vouchering. Moreover, P. retusa may represent a species complex in cryptic speciation, since it is widespread and has low hosts specificity.

The necessity of the typification of the Apocynum L. s.l. (incl. Poacynum Baill. and Trachomitum Woodson) (Apocynaceae) species is crucial for future dogbane diversity estimations. Still, the original material of many taxa of the genus Apocynum s.l. is doubtful or remains to be discovered. This study’s topic is resolving a long-term taxonomic homonymy around the widely used binomial “A. sibiricum”. The misusing of the name “A. sibiricum” became a reason for long-term misunderstanding of the meaning of the binomial Poacynum sarmatiense (Woodson) Mavrodiev, Laktionov & Yu.E.Alexeev (A. sarmatiense (Woodson) Wissjul.; T. sarmatiense Woodson) and therefore for the misestimation of the Apocynum s.l. diversity in Russian and other Eurasian floras. Resolving this issue, here, we designate the lectotype of A. sibiricum Jacq. and the name “A. sibiricum Pall.” was validated within Poacynum as P. pallasianum Mavrodiev, Sytin, Laktionov & Vasjukov nom. nov. (Apocynum sibiricum auct., non Jacq.) with the lectotype selected from the original collections of Peter Simon Pallas.

Specimens belonging to a new species in the genus Protocirrineris have been found during surveys along the southwestern coasts of the Netherlands. Protocirrineris stormae sp. nov, as described herein, were collected from the muddy bottom sediments in enclosed marine waterbodies and estuaries. This species is characterized by branchiae commencing from the first chaetiger and tentacular filaments arranged in two groups arising from chaetigers 2–3 that present one/two pairs of lobes, each bearing a single dorsal tentacle. From the current records of this species, it seems that P. stormae has an affinity for enclosed marine environments or parts of estuaries with minimal variability in salinity, higher transparency, and normal temperature regime. The discovery and study of this species contributes to a comprehensive characterization of benthic fauna in locations subjected to particular environmental stresses. Considering the extensive dataset available from the Southwestern Netherlands due to many years of sampling, it is plausible that P. stormae is a pseudo-indigenous species as there seem to be no records of similar or unknown Protocirrineris before 2013.

We report a new species of shearwater, Ardenna buchananbrowni sp. nov., from the Pliocene of New Zealand. It is both the smallest and oldest known diving member of the genus, demonstrating that this now abundant form of shearwater has had a long presence in southern oceans. Ardenna buchananbrowni sp. nov. is among the few extinct shearwaters described from the Southern Hemisphere and adds to an increasingly diverse seabird assemblage in the Pliocene of the region.

The genus Trogolaphysa comprises 81 described species distributed across the Neotropical and Afrotropical regions. In the Americas, just over half of the species found in subterranean habitats have a reduced eye number (0–5 eyes). Subterranean species are of interest as models to study the evolution of morphological adaptations. Many subterranean species of Trogolaphysa were described before the introduction of chaetotaxy as a diagnostic tool and thus remain incompletely described and diagnosed. To identify gaps in descriptions and facilitate the identification of newly collected forms, we provide standardized summary descriptions, species diagnoses, diagnostic tables, and a dichotomous key to the 33 Neotropical species of Trogolaphysa with reduced eye number. As a result of this synthesis, we describe two new troglobiontic species, Trogolaphysa reneaui n. sp. and Trogolaphysa welchi n. sp. from Belizean caves.

The freshwater Pannus genus comprises cyanobacterial unicellular species with a particular morphology, forming free-floating rounded colonies with thin, homogenous, and colorless colonial mucilage. There is little literature on the taxonomy of the Pannus and none on its metabolism. This study presents the first genomic characterization of a Pannus strain isolated from Pantanal Biome, Brazil. The genome was assembled into 117 contigs with a total size of 5.1 Mb and 99.12% completeness. It contained 4988 protein-encoding genes, including some involved in secondary metabolite biosynthesis, such as cyanobactin and terpenes. Interestingly, P. brasiliensis CCIBt3594 has a complete set of nitrogen fixation genes and is a non-heterocytou unicellular cyanobacterium. Finally, the phylogenomic analyses revealed the lack of information on closely related strains and anchored the genus Pannus within the order Chroococcales, Microcystaceae family, closest to Microcystis spp. representatives. This work presents novel evidence concerning a sparsely characterized genus of the Cyanobacteria phylum and contributes to elucidating taxonomic and systematic issues within the group of unicellular cyanobacteria.

This study explores the Swedish diversity of the thrips families Aeolothripidae and Melanthripidae. Currently, a total of 12 species in 2 genera of Aeolothripidae occur in Sweden, and 1 in Melanthripidae. The aims of this study include to provide an updated identification key with photographic material and an updated checklist of the country with provincial records. In this study both museum material and new material collected in understudied provinces are included, and a large number of molecular barcodes are produced. The results reveal 26 new provincial records in Sweden, predominantly in northern regions, and 11 provinces in total had new species records. New records of Rhipidothrips brunneus Williams 1913 warranted an examination of distinguishing characters compared to R. niveipennis Reuter, 1899. The original description of R. niveipennis is found to lack sufficient characters to delimit the species, and a redescription based on syntypes is presented.

Anadenanthera colubrina (Acol) and Anadenanthera peregrina (Aper) (Fabaceae) are two species popularly known as “angicos” that occur in seasonally dry tropical forest (SDTR) remnants in Brazil. Since many of the morphological characteristics of Anadenanthera species are superimposed and species-specific characteristics are difficult to observe, their identification is complex. Therefore, in this research, a set of ISSR (Inter-Simple Sequence Repeat Polymorphic DNA) molecular markers was standardized, aiming to characterize A. colubrina and A. peregrina species and study the genetic diversity of three populations of each species located within a fragmented landscape in São Paulo State, southeastern Brazil. Seven ISSR markers (UBC 2, 820, 851, 858, 864, 866, and 886) that show polymorphism for both species were used. The Bayesian cluster, PCoA and dendrogram analysis show that the total sample divides into two groups corresponding to each species. Also, a genetic divergence (Gst = 0.143) and a high number of migrants per generation (Nm = 3.0) were detected between them. The Acol populations showed significantly higher values for mean genetic diversity (h = 0.30) than Aper (h = 0.25) (p < 0.05). The ISSR marker UBC2250bp showed species-specific electrophoretic fingerprints for both species. The molecular tools generated herein support the conservation of Anadenanthera sp. and the restoration of vegetation where the species naturally occurs.

The long-horn bee genus Tetralonia consists of 35 Western Palaearctic species that are associated mostly with the family Asteraceae as host plants. A minority of the species are, however, exclusively associated with other host plants that have particularly large pollen grains, such as those in the plant families Caprifoliaceae, Malvaceae, and Onagraceae. This work presents a taxonomic account and morphological description of the assemblages of Tetralonia species with atypical (non-Asteraceae) host plants. It includes a key to the pollinosa-group, which contains most of the species, a description of three regionally restricted new species, namely T. eoacinctella Dorchin sp. nov., T. epilobii Dorchin sp. nov., and T. stellipilis Dorchin sp. nov., a lectotype designation for Eucera cinctella Saunders, 1908 [=Tetralonia cinctella (Saunders, 1908)], and a neotype designation for Apis malvae Rossi, 1790 [=Tetralonia malvae (Rossi, 1790)]. In addition, the name Eucera macroglossa Illiger, 1806 is confirmed as a synonym of Apis malvae Rossi, 1790; Tetralonia macroglossa ssp. xanthopyga Alfken, 1936 is officially placed in synonymy with Apis malvae Rossi, 1790; and Macrocera confusa Pérez, 1902 is listed as a doubtful synonym of Tetralonia scabiosae Mocsàry, 1879 (syn. nov.).

Sideritis royoi is found in the rocky limestone habitats of the Port Massif (southern Catalonia, Spain). The species was first collected by the local botanist Lluís de Torres in the late part of the 20th century, but the specimens have remained unidentified positively in herbaria for over 40 years. Sideritis royoi likely belongs to section Sideritis subsection Hyssopifoliae and shows some morphological affinities with the relatively widespread South European species S. hyssopifolia L., but it differs from this species because it has subspinescent upper leaves, the main surfaces of its leaves are glabrous or glabrescent, the main abaxial surface of its bracts is without eglandular hairs, and due to the fact that it has shorter inflorescences. Weaker similarities have also been observed with some species belonging to S. subsection Fruticulosae Obón & D.Rivera. In this paper, a description for the new orophilous species is provided, along with a detailed illustration, field photographs, and a comparison with closely related species. We include an assessment of its conservation status and a dichotomous key for the identification of all the species of Sideritis subsection Hyssopifoliae.

The Holarctic ground beetle genus Trechus Clairville, 1806, is highly diverse in the Ethiopian highlands, both in terms of species numbers and morphology. Particularly noteworthy are the extraordinarily large species of the subgenus Abyssinotus Quéinnec and Ollivier, 2021, with a body length up to 8.5 mm, that occur on Mt. Choke in northern Ethiopia. Recent, intensive field work on Mt. Choke resulted in a significantly large number of specimens that are the basis for our taxonomic revision of the species related to the giant species, T. dimorphicus Pawłowski, 2001 and T. gigas Pawłowski, 2001. We describe three new species and one new subspecies and discuss a likely interspecific hybrid that combines morphological character states of representatives of the dimorphicus and gigas subgroups of Abyssinotus. An iconography of males and females as well as photographs of the aedeagi of all the considered species are presented. The distributions of the species are detailed and knowledge of the species-specific habitat preferences is summarized. Based on the distributions and habitat specificity, a threat assessment based on the current land use pattern at Mt. Choke is provided.

The Neotropical deer genus Mazama is characterized by homoplastic morphological characters, a high karyotypic diversity, and a polyphyletic condition. The species of the genus have been recovered into two multigeneric lineages, the subtribes Odocoileina and Blastocerina, of the tribe Odocoileini (New World deer) in the family Cervidae. Within the Blastocerina, gray brockets include two non-sister species, Subulo gouazoubira, occurring south of the Amazon region, and Passalites nemorivagus, occurring in the Guianas and in the Amazon region. We clarify the taxonomic status and phylogenetic position of Mazama americana citus Osgood, 1912 (referred to as either S. gouazoubira or P. nemorivagus by other authors). We collected a topotype of M. a. citus from the eastern shore of Lake Maracaibo, Venezuela, characterize it morphologically and cytogenetically (conventional banding and fluorescence in situ hybridization), and carry out a phylogenetic analysis of its whole mitogenome and Cytb alongside two additional specimens of M. a. citus from northwestern Venezuela. Our analyses reveal the topotype to be a large gray brocket with a cinnamon band above the eyes and 2n = 61 and FN = 70 karyotype. Using cattle whole chromosome painting and bacterial artificial chromosome X probes, we determined its karyotype to differ in at least 10 rearrangements from that of S. gouazoubira. Bayesian inference recovers M. a. citus within the Blastocerina subtribe, separated phylogenetically from other gray brockets (100% branch value), revealing the Osgood’s gray brocket to be a valid species that should be assigned to a new genus. We propose the generic name Bisbalus, with Bisbalus citus (Osgood, 1912) as the type species.

In this study a new species of Gonolobus, G. villasenorii, is described. It is endemic to Sinaloa, Mexico, distributed in the Sierra Madre Occidental in pine–oak forest. This species is characterized by the presence of lanceolate sepals, margin of the corolla lobes with a whitish-green callus, without being cristate, and anthers with rectangular dorsal appendages. The new species is compared to Gonolobus chloranthus and Gonolobus erianthus. Gonolobus grandiflorus, Gonolobus incerianus, and Gonolobus lozadae are species with which it shares reticulate corollas and flowers more than 2 cm in diameter. A detailed description of the new species includes data on its habitat, ecology, phenology, conservation status, a distribution map, and a section where the new species is compared with similar species and how to recognize it.
