Plant species established on the basis of early garden cultivation may have lacked the original information about their native geographical origin. Crambe suecica was originally described from its 18th-century cultivation in the Chelsea Physic Garden in London, raised from seeds without provenance that were sent from Saint Petersburg. This species has been misunderstood as native to the Baltic Sea coasts and, consequently, misinterpreted as a taxonomic synonym of C. maritima. We infer from plant morphology and the history of Russian botany that seeds of C. suecica were originally collected by Johann Christian Buxbaum in 1726 when he travelled across the Ottoman Empire and then-Russian Transcaucasia, most likely in the Gilan or Mazandaran provinces of present-day Iran. According to the morphology of its type specimen, this taxon represents a glabrous variant of C. orientalis and is hereby reduced to a synonym of the latter species. The name C. pinnatifida has been misapplied to a species native to south-eastern Europe and the north-western Caucasus. This species name is nomenclaturally superfluous and illegitimate because its protologue includes a reference to C. suecica, which is to be treated as its type-bearing synonym. This case underlines the importance of historical research in nomenclatural studies, which may be required to reach a correct taxonomic decision. Full article

Fungal diversity has been well explored worldwide, but such knowledge in special environments remains limited. Here, we focus on the soil from Ngari Prefecture with high altitude in the northwestern part of Xizang, China. Among the 514 fungal strains isolated from the soil samples, two strains are newly described as Cymostachys pangongensis and Emericellopsis rutogensis in the Hypocreales on the basis of both morphological and phylogenetic evidence. Cymostachys pangongensis exhibits typical characteristics of Cymostachys, viz., irregularly cymosely branched conidiophores and olivaceous brown to dark brown, fabiform conidia. It represents the sixth known species of Cymostachys and the first species isolated from soils in this genus. Emericellopsis rutogensis has typical chlamydospores and conidia of Emericellopsis, although its sexual ascomata and ascospores were not observed. Notably, these two new species belong to interesting fungal genera, whose members are well known for rich medicinal natural products. In summary, this study enriches the knowledge of fungal diversity in special environments, and the isolated strains may provide important bioresources for future applications. Full article

The genus Lygodactylus includes a highly diverse and morphologically cryptic radiation of African dwarf geckos. Within the poorly known L. angularis group, the taxonomic distinction between L. heeneni and L. paurospilus has long been uncertain and controversial. Using newly available material from multiple localities of these taxa, combined with morphological and mitochondrial (16S rRNA) data, this study reveals that both taxa form a single, well-supported genetic lineage. Genetic divergence values between these taxa fall below the 6% interspecific threshold noted in previous studies for Lygodactylus, and previously proposed diagnostic morphological traits completely overlap with each other. These findings indicate that L. paurospilus represents a junior synonym of L. heeneni, which is now recognized as a widespread and morphologically variable species inhabiting diverse environments in southeastern Democratic Republic of the Congo and northern Zambia. This study highlights the importance of integrative approaches for resolving species boundaries in cryptic reptile groups. Full article

Although an isosporan coccidian has been reported from the broad-headed skink, Plestiodon laticeps (Schneider), no acroeimerians are known from this reptile. A single fecal sample was collected by hand in June 2025 from a female P. laticeps from Nevada County, Arkansas, USA. The sample was placed in a vial containing 2.5% potassium dichromate. It was examined for sporulated oocysts after flotation in Sheather’s sugar solution, measured, and photographed. The skink was found to be passing a new species of Acroeimeria Paperna and Landsberg, 1989. Oocysts of Acroeimeria nevadaensis sp. n. were spheroidal with a smooth bi-layered wall, measured (L × W) 15.6 × 13.7 µm, and had a length/width (L/W) (shape index) average ratio of 1.1; micropyle and oocyst residuum were absent but one to two polar granule(s) were present. Sporocysts are ovoidal and measured 7.7 × 5.9 µm, L/W ratio of 1.3; Stieda, sub-Stieda, and para-Stieda bodies were absent. The sporocyst residuum was composed of a loose aggregate of various-sized granules between and across the sporozoites but sometimes a compact, rounded, or irregular mass. In addition, new data on oocysts matching the description of Choleoeimeria fasciatus from the same host are provided. Here, we document a description of a new species of Acroeimeria as well as provide a new host and geographic distribution record, photomicrographs, and mensural and morphological data for a choleoeimerian from this skink. This is the first acroeimerian reported to be from P. laticeps and, more importantly, the second known to be from members of the family Scincidae of the world. Full article

Rivomarginella morrisoni (Gastropoda: Marginellidae) is a narrowly distributed freshwater snail inhabiting drainage basins of central and southern Thailand. To clarify patterns of genetic differentiation across its range, 45 individuals from 11 sites across eight river basins were analyzed using two dominant molecular markers: sequence-related amplified polymorphism (SRAP) and inter-simple sequence repeats (ISSR). SRAP primers produced higher polymorphic information content (PIC) values than ISSR primers (0.35 vs. 0.27). Analysis of molecular variance (AMOVA) revealed strong population structure, with 80.29% of the genetic variation occurring among populations and 19.71% within populations Population differentiation statistic (PhiPT) = 0.803, p < 0.001). Unweighted Pair Group Method with Arithmetic mean (UPGMA) and principal coordinate analysis (PCoA) consistently separated central and southern populations, and STRUCTURE supported K = 2 as the most likely number of clusters. Similarly, principal component analysis (PCA) of morphological traits also distinguished specimens into two groups corresponding to these geographic regions, confirming region-specific divergence. Overall, the genetic and morphological patterns indicate restricted gene flow among basins and a clear separation between central and southern lineages of R. morrisoni. This study provides the first molecular evidence of population structure in this species and offers important baseline information for future taxonomic, ecological, and conservation research on freshwater marginellid snails.

We describe a new species of Desmoscolex collected from subtidal muddy sediments off Jindo Island, on the southern margin of Korea’s west coast. Desmoscolex (Desmoscolex) curuvus sp. nov. is distinguished by 17 main rings, a 9/8 somatic setal arrangement, subdorsal setae with a slightly swollen and hollow distal end, an oval head with laterally extended foreign material, a rounded amphidial fovea confined within the head region, and broad cephalic setae bearing a fine central canal with lateral membranes. The terminal ring is strongly bent ventrally. Females exhibit pronounced sexual dimorphism, including a pair of dorsal setae on the thirteenth main ring and a thicker terminal ring (maximum width 25–26 μm in males and 24–31 μm in females). High-resolution scanning electron microscopy (SEM) observations revealed a distinctive lip-region ultrastructure composed of a tuberculate membrane and six fragment-like membranous elements, representing a rare configuration within the genus. By documenting a new species possessing membranous structures in the cephalic setae and providing detailed ultrastructural characterization of the lip region, this study offers important new evidence for refining species delimitations in Desmoscolex. These findings underscore the diagnostic value of lip-region morphology and highlight the need for targeted sampling and further ultrastructural analyses to better resolve the hidden morphological diversity of the genus, particularly in the underexplored northwestern Pacific.

The debate of the validity of Maylandia vs. Metriaclima as a genus for a group of rock-dwelling cichlids (Pseudotropheus zebra complex) in Lake Malawi, Africa, has been argued for more than 25 years. Probably the most important requirement in describing new zoological taxa is Article 13.1.1 of the International Code of Zoological Nomenclature (ICZN, 4th edition). We demonstrate that the description of Maylandia did not meet these requirements. Thus, we maintain that Maylandia remains a nomen nudum. Full article

The mitochondrial genome of Decametra tigrina (A.H. Clark, 1907) was fully sequenced and characterized. This circular, double-stranded genome spans 15,794 bp and encompasses 13 protein-coding genes (PCGs), 22 tRNA genes, and two rRNA genes. The arrangement of genes remains conserved, matching those of Cenometra bella and the MW405444 (submitted to GenBank as Oligometra serripinna). The base composition consists of 24.6% A, 47.6% T, 16.2% G, and 11.6% C. Most PCGs use ‘ATG’ as the initiation codon, with NADH4L and NADH5 initiating with ‘GTG’. Each PCG terminates with a complete stop codon (‘TAA’ or ‘TAG’). Twelve tRNA genes, three NADH genes, and two rRNA genes are located on the L strand, while the remaining genes reside on the H strand. Phylogenetic analysis utilizing all 13 PCGs demonstrated that D. tigrina forms a clade with MW405444 (submitted to GenBank as O. serripinna, reassessed here as D. tigrina) and Florometra sp. (MN883538). Decametra tigrina forms a sister group with C. bella; together, they cluster with Stephanometra indica (Mariametridae) and Zygometra comata (Zygometridae) in the ML tree. Full article

DNA barcode sequences remain unavailable for many species of Mexican Coleoptera. This study presents the first COI barcode records for four saproxylophagous beetle species (Coleoptera: Buprestidae, Cerambycidae) from the Central Valleys of Oaxaca, Mexico: Acmaeodera scalaris, Placosternus erythropus, Parevander xanthomelas, and Stenaspis castaneipennis. The sequences, together with their associated metadata, were deposited in the Barcode of Life Data System (BOLD) under the project Oaxaca Central Valley Insect Diversity (OCVID). A. scalaris is newly barcoded for Mexico, while the other three species are newly represented in global barcode databases. The P. xanthomelas barcode differs by approximately 8% from a GenBank sequence labeled with the same name, suggesting either a misidentified reference or a cryptic mitochondrial lineage. These data expand the molecular reference coverage for Neotropical Buprestidae and Cerambycidae and highlight the need for additional taxonomic work to refine species boundaries within Cerambycidae.

The new estuarine goby Eugnathogobius ganuensis n. sp. is described from 5 specimens (4 males: 27.0–31.5 mm standard length; 1 female: 27.5 mm standard length) collected from a small ditch in the lower reach of the Terengganu River basin, east coast of Peninsular Malaysia. The new species is easily distinguished from other congeners, except E. kabilia, by the following a combination of characteristics: 16 segmented caudal-fin rays; 30 or 31 longitudinal scale lows; high first dorsal fin (especially in males); no head pores; shoulder with oblique black band; transverse black markings on each scale; paired black blotches on caudal-fin base; and distinct black dots on upper caudal fin. Although E. kabilia is very similar to the new species, the latter has a shorter jaw in males (well-extended in the former), high first dorsal fin (low), first dorsal-fin second spine length > 16.8% of standard length (<13.6%), throat yellowish in the fresh condition (whitish), and a yellowish second dorsal fin (reddish in males of E. kabilia). Because the type locality of the new species is clearly not a natural environmental feature and no salinity during the low tide, despite being included in the tidal area, the true habitat is suggested as being the upper reaches of estuarine areas.

Boesenbergia burmanica Boonma, P.Saensouk & Saensouk, a new species from Naypyidaw Union Territory, Myanmar, is described based on morphological examination of specimens collected during field surveys in 2024–2025. The genus Boesenbergia is taxonomically complex, and ongoing botanical exploration in Southeast Asia continues to reveal undescribed taxa. Comparative analyses of living plants, herbarium materials, and published descriptions were conducted to determine diagnostic features. Boesenbergia burmanica is closely related to B. meghalayensis Aishwarya & M.Sabu but differs in having ovoid, branched rhizomes, a pubescent lamina on both surfaces, and an oblanceolate labellum with bright red markings. It grows in shady, sandy-loam habitats at 140–145 m elevation and flowers from August to September, producing inflorescences with nine to ten flowers. Species of Boesenbergia are traditionally used in Myanmar and neighboring regions as medicinal and ornamental plants, and notes on local ethnobotanical knowledge are provided. The new species exhibits high ornamental potential due to its compact clumping habit and attractive floral coloration. Cultivation guidelines are provided to support ex situ conservation and horticultural development for sustainable use. This discovery increases the number of Boesenbergia species recorded in Myanmar to 14 and highlights the importance of continued field-based taxonomic and conservation research on regional Zingiberaceae diversity.

In the present study, the occurrence of Garra substrictorostris Roni & Vishwanath, 2018, (Cypriniformes: Cyprinidae) was recorded for the first time from the Manas River in the Brahmaputra drainage system, thereby expanding the species’ distributional range. Two specimens were collected and identified to the species level using the existing literature. Mitochondrial Cytochrome C Oxidase subunit I (COI) gene barcoding was conducted to confirm the identity of the specimens collected from the Manas River. Morphological examination revealed characteristics consistent with the original description of G. substrictorostris from the Barak River drainage area. These findings were further corroborated by molecular data, specifically mitochondrial COI gene barcoding. The genetic distance between Garra substrictorostris and G. nasuta was observed to be 4.05%, inferring G. nasuta to be the closest relative and G. lissorhynchus to be the most distant species (15.45%), forming a different clade among the reported species within the genus Garra. A maximum likelihood (ML) and Bayesian inference phylogenetic trees were also constructed, which signify the correct identification of the species. Full article
