Coloration patterns in polyclad flatworms of the Pseudocerotidae family are crucial for taxonomic identifications, often serving as key diagnostic character. In this study, we document two pseudocerotid species from the Mexican Pacific exhibiting remarkably similar coloration patterns yet belonging to distinct genera. Through detailed morphological analysis of both external and internal characters, we describe a new species, Pseudobiceros deliae sp. nov. Coria, Bolaños and Quiroga, and report Pseudoceros josei as a new record for Baja California Sur, Revillagigedo Archipelago and Guerrero. Additionally, we provide 28S ribosomal DNA sequences to support future research efforts. Our findings demonstrate that species identification cannot rely solely on distinctive coloration patterns but rather requires a combination of traits, including other external morphological characteristics such as the number of male gonopores, the type of pharynx and the shape of pseudotentacles. Furthermore, we propose that Pseudoceros bicuti is a junior synonym of Pseudoceros josei. Full article

Discovery of Two New European Tree Trunk-Dwelling Medetera Species (Diptera: Dolichopodidae)
by Marc Pollet, Christopher Martin Drake, Maarten Jacobs and Andreas Stark
Taxonomy 2025, 5(1), 7; https://doi.org/10.3390/taxonomy5010007 - 7 Feb 2025
Abstract
Two new European species in Medetera (Diptera: Dolichopodidae) are described here. Medetera demirae sp. nov.—named after the Flemish minister for Justice and Enforcement, Environment, Energy and Tourism (2019–2024)—has been discovered at three localities in the eastern province of Limburg (Flanders, Belgium) and is [...] Read more.
Two new European species in Medetera (Diptera: Dolichopodidae) are described here. Medetera demirae sp. nov.—named after the Flemish minister for Justice and Enforcement, Environment, Energy and Tourism (2019–2024)—has been discovered at three localities in the eastern province of Limburg (Flanders, Belgium) and is thus far only known from this area. It can be easily recognized by a dentate hypandrium and phallus, a unique character not found in any other known Medetera species. M. nigrohalteralis sp. nov. had long been regarded as Medetera takagii Negrobov, 1970 by European dolichopodid workers but ultimately proved to represent a separate species. This species seems widespread in northwestern and central Europe. Morphologically, it is very similar to M. takagii and M. tristis (Zetterstedt, 1838) and shares an infuscate halter with both species. It differs from both by the shape of its hypandrium and surstylus. M. demirae sp. nov., large numbers of M. nigrohalteralis sp. nov., and other rarely seen Medetera species were collected in Belgium using a new type of tree trunk eclector. A widespread application of this trap might considerably change our view on the occurrence and rarity of tree trunk-dwelling invertebrates. Full article

Lotus, with about 120 species, is the largest genus of Leguminosae–Loteae. The last global classification recognized 14 sections, of which 13 were then sampled in molecular phylogenetic analyses. The section remaining unsampled is Lotus sect. Benedictella with one critically endangered and possibly extinct species, L. benoistii. This is an annual species known from Mediterranean-type vernal pools in the lowlands of northwestern Morocco that differs from other species of the genus in many-seeded indehiscent fruits with thin pericarp and pinnate leaves with 6–9 leaflets. This species was described in a monospecific genus and later transferred to Lotus on the basis of suggested morphological similarities with three mainly desert annuals from North Africa and Southwest Asia currently classified in Lotus sect. Chamaelotus. We provide the first molecular phylogenetic data on L. benoistii and show that it is far from L. sect. Chamaelotus. It is close to plants traditionally classified in Lotus sect. Lotus that have a center of diversity in Europe and temperate Asia. Phylogenetic analyses of plastid markers showed that L. sect. Chamaelotus belongs to a clade with major taxonomic diversity in Macaronesia, Africa, SW Asia, and Australia. Morphology does not provide arguments against the novel hypothesis on the relationships of L. benoistii. Its possible extinction is a great loss for the breeding programs of the pasture plant L. corniculatus. We provide the first anatomical data of L. benoistii, showing that its non-shattering condition has a peculiar nature that differs from all other instances of indehiscence in Loteae. Full article

Actinomycetes are known to produce a vast array of bioactive secondary metabolites with potential therapeutic applications, including antimicrobials, anticancer agents, and enzyme inhibitors. Among these, members of the genus Nonomuraea have received much attention due to their broad ecological importance in nutrient cycling in soil and their ability to produce new bioactive compounds. A novel actinomycetes, designated strain M3C6T, was isolated from soil samples collected on Marmara Island, located in the Istanbul province, aiming to explore the microbial diversity of unexplored habitats, and characterized using a polyphasic approach. The isolate showed chemotaxonomic and morphological features consistent with members of the genus Nonomuraea. The 16S rRNA gene sequence analysis revealed that strain M3C6T shared the highest similarity, at 98.7% sequence identity, to Nonomuraea basaltis 160415T and Nonomuraea turkmeniaca DSM 43926T. However, the ANI and dDDH values between strain M3C6T and these reference strains were fairly low, ranging from 84.0 to 84.6% and 31.8 to 33.7%, respectively, below the generally accepted cutoffs for ANI and DDH that delineate different prokaryotic species. Genomic analysis of strain M3C6T showed that it had a genome size of 10.38 Mbp and a DNA G+C content of 69.5 mol%. Based on these chemotaxonomic, phenotypic, and genomic data, strain M3C6T is classified as a novel species within the genus Nonomuraea, for which the name Nonomuraea marmarensis sp. nov. is proposed. The type strain is M3C6T (= KCTC 49983T = CGMCC 4.8035T). Genomic analyses confirmed the high potential of M3C6T to produce specialized secondary metabolites. Full article

Krameropteris is an extinct fern genus found in mid-Cretaceous Myanmar amber, assigned to the Dennstaedtiaceae, with only one previously described species, i.e., K. resinatus. This study describes a new species, K. calophyllum, also preserved in Myanmar amber. The new species is characterized by branched venation with free veinlets terminating in thickened tips, multicellular hairs along the pinnule margins, and submarginal or medial exindusiate sori at the ends of veinlets. Its sporangia are polypod-type, producing trilete spores. This new species represents the second record of an extinct fern genus of the early-diverging Dennstaedtiaceae lineage found in Myanmar amber. Krameropteris calophyllum differs from K. resinatus in its pinnule epidermal characteristics and spore morphology, with the latter exhibiting a conspicuously ornamented perine, covered with sparse tubercles and ridges. The new species provides insights into potential herbivory interactions and the relationship between mid-Cretaceous polypod ferns and the smallest mite ever recorded. These findings suggest that Dennstaedtiaceae exhibited species-level diversity by the mid-Cretaceous, indicating an earlier origin of the family, potentially as early as the Early Jurassic, consistent with recent DNA-based time divergence estimates.

Abstract
The genus Hypoglyptus Gerstaecker, 1855 is herein revised for the first time. Based on adult morphological characters, five species are recognized as valid: Hypoglyptus conspersus (Leonhard, 1912) (Greece), H. elegans (Brullé, 1832) (Greece, Albania), H. gracilis Kiesenwetter, 1864 (Greece), H. graecus (Pic, 1902) (Greece), [...] Read more.
The genus Hypoglyptus Gerstaecker, 1855 is herein revised for the first time. Based on adult morphological characters, five species are recognized as valid: Hypoglyptus conspersus (Leonhard, 1912) (Greece), H. elegans (Brullé, 1832) (Greece, Albania), H. gracilis Kiesenwetter, 1864 (Greece), H. graecus (Pic, 1902) (Greece), H. heydeni Faust, 1889 (Greece, Syria, Turkey). For this last species a lectotype is designated. Hypoglyptus pictus Gerstaecker, 1855 is proposed as n. syn. of H. elegans (Brullé, 1832). Male and female genitalia have been examined and are illustrated for the first time. The five species are very similar to and separable from each other by a few subtle differences in the shape, the sculpture, and the vestiture of the pronotum and elytra and in the more or less toothed femora. On the basis of morphological characters, the genus Hypoglyptus, previously incertae sedis in Curculionidae, is here tentatively placed in the tribe Smicronychini of the subfamily Curculioninae.
