[Herpetology • 2025] Elaiophis gen. n. • Generic Affinities of African House Snakes Revised: A New Genus for Lamprophis inornatus (Serpentes: Lamprophiidae: Lamprophiinae: Boaedontini)

 

  Elaiophis inornatus (Duméril, Bibron & Duméril, 1854) comb. n.
Elaiophis gen. n. 

Tiutenko, Maliuk & Koch, 2025
 Salamandra. 61(2); 

Abstract
 This article is the second part of a revision of the systematics of Boaedontini Dowling, 1969 and a follow-up to the work by Tiutenko et al. (2022). As a result of morphological and phylogenetic analyses, further taxonomic actions are taken in the genus Lycodonomorphus Fitzinger, 1843. Lamprophis inornatus Duméril, Bibron & Duméril, 1854, a species initially described in the genus Lamprophis and subsequently assigned to Lycodonomorphus, is here transferred to a new monotypic genus on a basis of combined criteria including genetic distance, morphology, ecology and biogeography. For improved taxonomic stability of the species and the new genus, a neotype for L. inornatus is designated from the specimen ZFMK 032712. The lectotype of Boodon infernalis Günther, 1858 is designated from one of three extant syntypes NHMUK 1858.4.11.5 and the type locality of this species, that is currently treated as a junior synonym of L. inornatus, is restricted to Durban, South Africa. The name ‘infernalis’ should be available if the species status of this northern clade would become restored. Lycodonomorphus subtaeniatus Laurent, 1954, another former Lycodonomorphus species long assumed to be a member of Boaedon, is here formally assigned to this genus and tentatively placed next to Boaedon upembae (Laurent, 1954) and Boaedon virgatus (Hallowell, 1854) on a basis of pholidosis, cranial morphology and dentition. The tribe Boaedontini now contains nine genera that can be separated by morphological characters according to the proposed key. The genus Lycodonomorphus still requires attention of taxonomists, as it contains species, such as L. bicolor, L. laevissimus, L. leleupi, L. mlanjensis, L. obscuriventris, and L. whytii, with uncertain taxonomic position and in this sense has to be viewed as sensu lato.

Elaiophis gen. n. 

Type species: Lamprophis inornatus Duméril, Bibron & Duméril, 1854,
 by present designation. 

Diagnosis: Body cylindric, moderately short. Head moderately depressed. Eye medium-sized to small. Tail short, representing ca. 12–15% of the total length. Head trapezoidal, broader posteriorly, moderately distinct from neck. Snout blunt, square-shaped. Rostral rather large, approximately as high as broad, well visible from below and above. Nasal divided. Eye medium-sized, with wide sub-elliptical pupil. Anterior chin shields equal in size to the posterior or slightly longer. Loreal single, rectangular, horizontally elongate. No labial pits. No loreal grooves. Dorsal scales with two apical pits, arranged in 23 rows at the middle of the body. Subcaudals paired. Anal entire. 18–19 maxillary, 10–11 palatine, 17–19 pterygoid, 20–23 mandibular teeth. No diastemata. Maxillary teeth subequal. Mandibular teeth 2–7 strongly enlarged. Hemipenis bilobal, shallowly forked; sulcus spermaticus centrifugal, dividing approximately half way up shaft. Dorsal colour olive-green, olive, dark brownish olive, glaucous, dark neutral grey. Ventral colour cream white, or pale neutral grey

Content: The genus is currently monotypic, containing one species – Elaiophis inornatus (Duméril, Bibron & Duméril, 1854) comb. n.

Etymology: In South Africa where this snake is distributed it is called ‘Olive Snake’ in English, or ’Olyfslang’ in Afrikaans. Both names refer to the dorsal colour. The new genus name ‘Elaiophis’ is a translation of these vernacular names into Latin, being a compound of the Greek words ὄφις (snake) and ἐλαία (olive). Since the head of the nominal compound (‘ophis’) is masculine, the new noun is of the same gender. As English name for the new genus, we suggest ‘African olive snakes’.

[PaleoBotany • 2025] Karkenia bracteata • A New Species of Karkenia (Ginkgoales: Karkeniaceae) from the Lower Jurassic of East Siberia (Russia): palaeobiogeographical and evolutionary implications

 
Karkenia bracteata
Frolov, Enushchenko & Mashchuk, 2025

 
Abstract
The family Karkeniaceae is the most ancient of the Ginkgoales. It is known from the lower Permian to the Lower Cretaceous. Cladistic analysis has shown that Karkeniaceae represents a distinct lineage among the Mesozoic ginkgoaleans and is much closer to Trichopitys. However, the absence of the complex ovule shoots of ginkgoaleans with remains of ‘intercalated bracts’ in the palaeontological record makes it difficult to reconstruct the transformation series linking Trichopityaceae to Karkeniaceae. Here, we report Karkenia bracteata sp. nov. from the Lower Jurassic of East Siberia (Russia). We examined impressions and compressions using light microscopy and scanning electron microscopy. Karkenia bracteata consists of the main axis bearing helically arranged bract–ovule complexes, each composed of a long laminar bract subtending and sheathing an ovule stalk with a single ovule. The presence of a bract distinguishes this species from all known Karkenia. However, the ovule structure, stomatal guard cells and megaspore membrane indicate that the new species belongs to Karkeniaceae. Karkenia could have evolved from Trichopitys due to reduction and condensation from an ancestral state. The ovulate short shoots must have fused to form a compact structure, while the main axis was strongly reduced. The leaves of such branches became reduced and further disappeared. Therefore, the leaves of the intermediate form between Trichopitys and Karkenia must have been bracts. Thus, K. bracteata corresponds to the hypothetical intermediate form linking Trichopityaceae to Karkeniaceae and confirms the hypothesis of the cone-like nature of Karkenia megastrobili.

Abstract
Meiogyne kwangtungensis is a rare species endemic to Hainan, China, known just from two fruiting collections made in the 1930s. Although it was published under the name Meiogyne in 1976, it was suggested that it might be better placed within Pseuduvaria or Mitrephora. For decades, this species was never collected again, thus its true generic affinity remained unresolved due to the lack of flowers. During a field exploration in Hainan, we re-discovered this species and collected a flowering specimen for the first time. The flower immediately confirmed its affinity with Pseuduvaria. Phylogenetic analyses of five chloroplast regions (psbA-trnH, trnL-F, matK, rbcL, and atpB-rbcL; ca. 4.2 kb, 70 accessions) also unambiguously placed Meiogyne kwangtungensis in the Pseuduvaria clade (PP = 1.00, ML BS = 99%). Morphologically, it is most similar to P. multiovulata which is endemic to Myanmar and Thailand, both with often-paired flowers, long pedicels and short peduncles, and often 1–2 monocarps. However, it differs in having smaller flowers with kidney-shaped glands on the inner petals, fewer stamens and carpels, smaller ovoid monocarps with an apicule and fewer seeds. On the basis of the combined molecular phylogenetic and morphological data, we propose a new combination, Pseuduvaria kwangtungensis (P.T.Li) Qing L.Wang & B.Xue. A full description including floral characters and a color plate are provided here for this species. A key to species in the genus Pseuduvaria in China is also provided.

[Herpetology • 2025] Paragehyra tsaranoro • A New microendemic Gecko (Squamata: Gekkonidae: Paragehyra) from the small forest fragments of south-eastern Madagascar


Paragehyra tsaranoro
Belluardo, Piccoli, Lobón-Rovira, Alves, Rasoazanany, Andreone, Rosa & Crottini, 2025 
 

Abstract
Historically, herpetological research in Madagascar has largely overlooked small forest fragments outside the country protected area network. Despite substantial declines in species diversity compared to large continuous forests, these fragments continue to sustain diverse herpetological communities and frequently harbour microendemic species. We describe a new gecko belonging to the genus Paragehyra, apparently microendemic to small and isolated forest fragments surrounding the Andringitra Massif in south-eastern Madagascar. Paragehyra tsaranoro sp. nov. is different from its congeneric species based on genetic distances in mitochondrial markers (16S and COI), phylogenetic position, and the lack of haplotype sharing at one nuclear locus (POMC). The new species is also distinguishable from its congeners based on a combination of 14 morphological characters. New genetic and morphological data are also provided for the sympatric P. felicitae and we propose a new assessment of its conservation status within the IUCN Red List. Paragehyra tsaranoro sp. nov. and P. felicitae are mostly found in forest fragments managed by local communities (community-managed reserves) outside legally protected areas. This study highlights the importance of community-based management for the conservation of local herpetofauna, particularly in regions heavily impacted by anthropogenic pressure and largely unsuitable for forest-dwelling species. The findings emphasise the importance of conducting research on small forest fragments, as they are essential for completing the inventory of Malagasy herpetofauna.

Horseshoe crabs are an ancient lineage of aquatic chelicerate arthropods traditionally considered to be “living fossils” exhibiting limited morphological change throughout their evolution. This paradigm is challenged by the divergent morphologies of Paleozoic and Mesozoic xiphosurans in nonmarine environments, which show greater variation of prosomal carapace shape. Marine horseshoe crabs appear to exhibit a more conservative evolutionary history punctuated by marked increases in body size during the Carboniferous and Jurassic. However, interpretation of horseshoe crab evolutionary trends is complicated by uncertainty over whether the smaller Paleozoic species represent adults or juveniles. Here, we describe a diminutive 445-million-year-old horseshoe crab, Lunataspis gundersoni sp. nov., preserving details of ovarian structures in the prosoma. Unique among Xiphosura, the new species possesses an unusually prolongated prosoma, indicating early morphological variation within the group. However, the female reproductive system appears identical to that of extant Tachypleinae. Critically, the presence of eggs demonstrates that the specimens are adults and that horseshoe crabs were significantly smaller in size during the Paleozoic. Lunataspis gundersoni displays a mixture of divergent external and conserved internal anatomy that reveals mosaic evolutionary patterns and illustrates early morphological variation among marine Xiphosura.

[Paleontology • 2025] Primicaris larvaformis • A tiny Cambrian stem-mandibulate reveals Independent Evolution of Limb Ttagmatization and Specialization in early Euarthropods


Primicaris larvaformis  Zhang, Han, Zhang, Liu & Shu, 2003

in Liu, Zeng, Zhao, Y. Zhu, Li, Yin et M. Zhu, 2025. 

Abstract
The mandibulate euarthropods are the most speciose animal group, but the evolutionary gaps in origin of mandibulate body plan remain unresolved. Marrellomorphs, a common Paleozoic euarthropod group, had a long evolutionary history from Cambrian to Devonian. With computed microtomography, here we report the fine-scale soft-bodied morphoanatomy of the oldest marrellomorph Primicaris larvaformis, a millimeters-sized euarthropod from the ~ 518-million-year-old Chengjiang biota, China. Primicaris possesses a body plan featuring morphologically similar post-antennular biramous appendages, but also mandibulate diagnostic features including multi-segmented exopodites, a well-developed and differentiated hypostome-labrum complex, and a pancrustacean-like topological configuration of frontalmost three pairs of appendages. Phylogenetic analysis resolves Acercostraca and Marrellida as stem-Mandibulata. The undifferentiated post-antennular appendages in Primicaris suggest a possibility that the head appendages acquired a crown-mandibulate configuration before their morphological specialization in mandibulate origin. The emergence of novel appendage morphotypes in Acercostraca and Marrellida reveals that the complexity of limb tagmatization evolved independently in different Euarthropoda clades.

[Botany • 2022] Gonolobus caamalii (Apocynaceae: Asclepiadoideae: Gonolobeae) • Twice Lost, Twice Found: A New Species with A Reappraisal of the Genus in the Yucatan Peninsula Biotic Province

in Carnevali, Romero-Gonzalez, Tapia-Muñoz, Ramírez-Morillo, Ramírez-Díaz, Cetzal-Ix, Duno de Stefano et Romero-Soler, 2022. 

Abstract
Gonolobus is reassessed in the Yucatan Peninsula Biotic Province (YPBP). The genus consists of seven taxa in the area: six species and two subspecies. These include a taxon that we propose here as a new species and the treatment of G. yucatanensis as a subspecies of G. stenanthus and the new combination G. stenanthus subsp. yucatanensis is proposed. These two taxa are endemic to the YPBP. The other species are G. barbatus (for which we propose a lectotype), G. cteniophorus, G. fraternus, G. glaberrimus, and G. leianthus. The new species is Gonolobus caamalii Carnevali & R. Duno, restricted to the Yucatán state in Mexico and distinguished by its corolla lobes with a dark purple (almost black) longitudinal, callose band along the proximal 2/3 on the right side of the lobes and a 1.1–1.3 mm broad, annular, continuous dark purple-black band surrounding the gynostemium and corona at the base of the corolla lobes. It appears related to G. leianthus from southern Megamexico, a species from humid forests at higher elevations and that differs in its larger flowers with broader corolla lobes and a strikingly different color pattern in the flowers. The new species is described, illustrated, and discussed. Entries for all Gonolobus species from the YPBP include a brief discussion and specimen citations. The conservation status of the Gonolobus taxa endemic to the YPBP are assessed either as as Endangered (EN) or as Near threatened (NT). Distributional maps for all Gonolobus from the area covered are presented. Finally, we offer a key to Gonolobus of the YPBP.

Abstract
Garra magnarostrum sp. nov. is described from the Ranga River, Brahmaputra River drainage in Arunachal Pradesh, India. It is distinguished from congeners in the Indian sub-continent, Myanmar and China in having (vs. lacking) many small and budding tubercles on the ventral side of the transverse lobe of the snout. It further differs from congeners in having a combination of the following characters: a multilobed proboscis on the snout, a long head, a long snout, small eye, a deep caudal peduncle, a small gular disc, 14½ branched pectoral-fin rays, 33 lateral line scales, 11 predorsal scales, 13 circumpeduncular scales and presence of multicuspid tubercles on the snout.

[Paleontology • 2025] Megaglomerospora lealiae • A new fossil fungus (Glomeromycetes) from upper Carboniferous of Portugal: the Largest glomeromycotan fungal spores

 

Megaglomerospora lealiae

in Correia, Sá et Pereira, 2025.
 
Highlights: 
• Fossil fungi discovered in the continental Carboniferous of Portugal.
• New fossil fungus is erected based on a dense cluster of unusual silicified large spores.
• Megaglomerospora lealiae is the first record of Glomeromycotan fungal spores from the Carboniferous of Iberia.
• Megaglomerospora lealiae represents the largest Glomeromycotan fungal spores documented so far.
• New insights on the diversity of the Glomeromycotan spores and the Carboniferous endomycorrhizal fungi.

Abstract
A new genus and species of fossil fungus, Megaglomerospora lealiae, is described from the Buçaco Carboniferous Basin (upper Stephanian C, Upper Pennsylvanian, upper Carboniferous), in central western Portugal. The new fossil fungus consists of a dense cluster of silicified large spores. These new fungal spores are oblong, subelliptical to subspherical-shaped, with a glabrous surface characterized by having a lipid-filled lumen, and display a strong septate-like hypha attached. The presence of lobe-shaped germination shields suggests close affinities to Diversisporales (Glomeromycota). Megaglomerospora lealiae nov. gen., nov. sp. is remarkably distinctive because it is by far the largest fossil fungal spore (∼1.6 mm long) documented for the phylum Glomeromycota. This is the first report of an endomycorrhizal‐like fungus from the Carboniferous of Iberia.

Abstract
The dawn of dinosaurs is marked by the appearance of the saurischian lineages in the Late Triassic fossil record, around 230 million years ago. This early burst of diversification of the group is majoritarily represented by sauropodomorphs and herrerasaurids in late Carnian to early Norian of Brazil, Argentina, India, and Zimbabwe. However, “silesaurids”, an older and enigmatic group of quadrupedal dinosauromorphs, were recently found, in some works, as stem ornithischians. In this scenario, dinosaurs would have originated far earlier than the end of the Ladinian, a time in which “silesaurids” are already spread through Gondwana. Despite being also recorded in more recent dinosaur-bearing beds in Brazil, “silesaurids” are absent in strata from the early Carnian, an important time frame for dinosaur evolution. Here we present a new “silesaurid”, Itaguyra occulta gen. et sp. nov., that fills up the remaining gap of occurrence of these dinosauromorphs and provides new clues to the success of these putative early ornithischians.

Itaguyra occulta gen. nov. et sp. nov.
 
Etymology: The genus name combines the native Tupi words Ita- (= stone) and -guyra (= bird), referring to the avemetatarsalian nature of the specimen. The specific epithet, derived from Latin, means hidden and refers to the fact that the remains were initially identified as being “mixed up” with other indeterminate cynodont fragments with which they had been collected.

 (A) Holotype UFRGS-PV-1365-T. (B) Placement of Rio Grande do Sul State (RS) in Brazil. (C) Exposure of the Santa Maria Supersequence in RS. (D) Locality of the type material (red star) and other correlated localities (pink stars). (E) Restoration of the skeleton (artwork by Maurício Garcia) with known elements in pink.


Holotype: UFRGS-PV-1365(a)-T, a left ilium (Fig. 1A).
Paratype: UFRGS-PV-1365(b)-T, associated ischium (Fig. 1A).

Type and referred locality: The type-materials were collected in the Schoenstatt Sanctuary fossil site (52°27′0.5″ W; 29°44′26.2″ S), in the Santa Cruz do Sul municipality (Fig. 1D), Rio Grande do Sul State, Brazil.

Diagnosis: Itaguyra occulta differs from all other known “silesaurids” with comparable material in (*local autapomorphy): having a faint crest connecting the preacetabular process and the supracetabular crest of the ilium, unlike the prominent ridge of most “silesaurids”*; height of the postacetabular process sub-equal to the height of the acetabulum (shared with Silesaurus opolensis and Kwanasaurus williamparkeri), differing from Lutungutali sitwensis and Gamatavus antiquus (see Discussion); supracetabular crest rounded (shared with Asilisaurus kongwe, Lewisuchus admixtus, Lutungutali sitwensis, and Gamatavus antiquus), unlike the straight outline of Ignotosaurus fragilis, and Kwanasaurus williamparkeri; brevis fossa almost entire visible in lateral view (shared with Silesaurus opolensis Kwanasaurus williamparkeri), being different from Lewisuchus admixtus and Asilisaurus kongwe which are more ventrally oriented; presence of a triangular process continuous to the posterior margin of the brevis fossa (absent in Gamatavus antiquus); triangular ventral margin of the medial wall of the iliac acetabulum (shared with Asilisaurus kongwe, Lutungutali sitwensis, Ignotosaurus fragilis and probably Gamatavus antiquus, but not with Silesaurus opolensis and Kwanasaurus williamparkeri); and, tall shaft of the ischium* (see Discussion).

Highlights: 
• After end-Permian mass extinction, the Triassic witnessed a super-radiation of modern insects (i.e., hymenopterans, dipterans, and lepidopterans).
• We report the oldest known record of hexapod scales, which were recovered from a megaherbivore dicynodont coprolite.
• The coprolite comes from a communal latrine in lower Carnian deposits (∼236 Ma) of the Chañares Formation, NW Argentina.
• The unique combination of features (e.g., ornamented hollow scales with internal lumen) suggests lepidopteran affinities.
• The Chañares scales contribute to the temporal mismatch between phylogenomic and fossil evidence of lepidopterans.

Abstract
Life on Earth nearly came to an end during the end-Permian mass extinction (EPME; c. 252 Ma). In its aftermath, the Triassic witnessed the adaptation of survivors to a postapocalyptic world and the establishment of modern ecosystems. Inland, these changes included an outstanding turnover between amniote groups triggered by the diversification of plants and arthropods. A super-radiation of morphologically modern insects occurred in the Triassic, including some of their most successful and ecologically relevant groups, such as Diptera (flies and mosquitoes) and Lepidoptera (moths and butterflies). Here, we describe the oldest evidence of hexapod scales, preserved within a megaherbivorous kannemeyeriiform dicynodont coprolite. This specimen comes from a communal latrine in the lower Carnian deposits (∼236 Ma) of the Chañares Formation, La Rioja Province, northwestern Argentina. The tiny fossil scales are hollow and ornamented, which is a synapomorphy of Lepidoptera and suggests that they could belong to this group. If this is the case, the Chañares scales would partially fill the temporal mismatch between phylogenomic date and the fossil evidence of butterflies and moths because they preceded the previously oldest lepidopteran record by c. 35 million years. Moreover, the scales have a combination of features present in early diverging glossatan lepidopterans. The inclusion of the temporal data provided by the Chañares scales into an updated temporal calibration of lepidopteran phylogeny shows that the proboscis, a key evolutionary novelty for the group (Glossata), evolved between c. 260–244 Ma. Thus, the proboscis-bearing lepidopterans would be part of the repertory of new plants and animals that diversified during the aftermath of the EPME.
