[Paleontology • 2024] Gaiasia jennyae • Giant stem Tetrapod was Apex Predator in Gondwanan late Palaeozoic Ice Age

  

Gaiasia jennyae

DOI: 10.1038/s41586-024-07572-0

Abstract

Current hypotheses of early tetrapod evolution posit close ecological and biogeographic ties to the extensive coal-producing wetlands of the Carboniferous palaeoequator with rapid replacement of archaic tetrapod groups by relatives of modern amniotes and lissamphibians in the late Carboniferous (about 307 million years ago). These hypotheses draw on a tetrapod fossil record that is almost entirely restricted to palaeoequatorial Pangea (Laurussia). Here we describe a new giant stem tetrapod, Gaiasia jennyae, from high-palaeolatitude (about 55° S) early Permian-aged (about 280 million years ago) deposits in Namibia that challenges this scenario. Gaiasia is represented by several large, semi-articulated skeletons characterized by a weakly ossified skull with a loosely articulated palate dominated by a broad diamond-shaped parasphenoid, a posteriorly projecting occiput, and enlarged, interlocking dentary and coronoid fangs. Phylogenetic analysis resolves Gaiasia within the tetrapod stem group as the sister taxon of the Carboniferous Colosteidae from Euramerica. Gaiasia is larger than all previously described digited stem tetrapods and provides evidence that continental tetrapods were well established in the cold-temperate latitudes of Gondwana during the final phases of the Carboniferous–Permian deglaciation. This points to a more global distribution of continental tetrapods during the Carboniferous–Permian transition and indicates that previous hypotheses of global tetrapod faunal turnover and dispersal at this time must be reconsidered.

ABSTRACT

Two new Psilocybe species (Hymenogastraceae), P. ingeli and P. maluti, are described from southern Africa. Morphology and phylogeny were used to separate the two novel fungi from their closest relatives in the genus. Psilocybe ingeli was found fruiting on bovine manure–enriched grasslands in the Kwa-Zulu Natal Province of South Africa and differs from its closest relative P. keralensis and others in the internal transcribed spacer ITS1-5.8S-ITS2, partial 28S nuc rDNA, and translation elongation factor 1-alpha regions, distribution, and having larger basidiospores. Similarly, P. maluti was collected from the Free State Province of South Africa and observed in the Kingdom of Lesotho, growing on bovine manure. A secotioid pileus, geographic distribution, and differences in the same DNA regions distinguish P. maluti from its closest relative P. chuxiongensis. Furthermore, the spore dispersal and traditional, spiritualistic use of P. maluti are discussed here.

Abstract

Background: The genus Pinguicula harbors 110 species, of which 53 are distributed in Mexico. The formation of the Mexican mountains has favored the Pinguicula diversification. Pinguicula specimens collected in the State of México, along the Trans-Mexican Volcanic Belt (TMVB) do not correspond with any known species.

Questions: Do the collected specimens belong to a new species? What is its conservation status? How many Pinguicula species are there along the TMVB and how do they differentiate? How is the Pinguicula species richness distributed?

Studied species: Pinguicula.

Study site and dates: TMVB, 2005-2023.

Methods: Based on herbarium specimens and recently collected material, a morphological analysis and description were made. Conservation status was assessed following IUCN Red List Categories and Criteria. Herbarium specimens and digital records of Pinguicula from the TMVB were examined to generate a list and key. We analyzed the richness distribution of Pinguicula by states, vegetation types, elevation ranges, and grid cells.

Results: Pinguicula tlahuica is proposed as a new species. It is distinguished by the linear-spatulate summer leaves. The new species falls into the Endangered (EN) category. Along the TMVB, 16 species of Pinguicula are distributed. The State of México, Hidalgo and Michoacán, and the pine-oak forest were the richest. Pinguicula appeared between 759-3,427 m asl. The grid cell analyses revealed different areas with high richness.

Conclusions: Along the TMVB, the Pinguicula species richness centered on the Eastern and Western sectors. Pinguicula crassifolia, P. michoacana, P. tlahuica, and P. zamudioana are endemic to the TMVB.

Abstract

Garter snakes in the genus Thamnophis from Mexico have a long and convoluted taxonomic history. From 2015 to 2022, we conducted a comprehensive sampling of Mexican Thamnophis species, aiming to link molecular phylogenies with the recognized species related to T. scalaris in the highlands of Mexico. Here, we present an analysis of mitochondrial DNA to resolve the status of two enigmatic highland Thamnophis populations. Our research resulted in the identification and morphological characterization of a previously undescribed Thamnophis species from the state of Jalisco in western Mexico. We also clarify the identity and relationships of several previously enigmatic populations of Thamnophis. This work presents new data for Thamnophis phylogenetics from the Mexican highlands and offers a framework for future conservation efforts.

Proposed standard English name: Ahumada’s Alpine Garter Snake.

Proposed standard Spanish name: Culebra Listonada de Montaña de Ahumada.

Diagnosis: A relatively small Garter Snake, with a maximum of 565 mm SVL and 705 TotL; head narrow, scarcely wider than neck, with a short muzzle (INK + PFK = 3.0 mm); tail long in length, 31–36% of SVL and 23–27% of TotLin males, 25–26% of SVL and 20–21% of TotLin females; internasals wider than long; frontal 2–2.25 times longer than wide; loreal slightly longer than wide; one preocular; 2–4 postoculars; temporals 1 + 2; 7 supralabials, third and fourth entering orbit; 9–10 infralabials, first four in contact with anterior chinshields; anterior chinshields shorter than posterior. Dorsal scales always in 19-17-17 rows, strongly keeled except for the outermost row, which is smooth; ventral scales in males 134–142, in females 139–141; subcaudals in males 61–69, in females 54–55; anal scale undivided. Dorsal pattern consists of a pale mid-vertebral stripe restricted to the mid-dorsal row and a pale lateral stripe on second scale row. One or two rows of dark brown or black dorso-lateral spots, usually in one row on the anterior third of the dorsum, then divided into two rows along the remaining posterior two thirds. Ventral coloration dark, pale anteriorly, becoming progressively darker until dark gray or black posteriorly.

Etymology: A patronym honoring Iván Trinidad Ahumada-Carrillo (1984–), who has made many contributions to diverse areas in herpetology, including extensive studies of the herpetofauna of Jalisco and Zacatecas. Iván collected the first specimen of this new species in the Sierra Cacoma (MZFZ 4593) and pointed out its distinctiveness from typical T. scalaris and T. errans.

Abstract

The newly discovered Paraphlomis youyangensis, native to southeastern Chongqing, China, is introduced to the scientific community. This species exhibits similarities in floral structure to P. kuankuoshuiensis but is distinguishable by several discrete features, such as less pronounced rhizomes (<0.5 vs. 2–4 cm), elongated stolons (present vs. absent), smaller leaf blades (1.8‒5.5 × 1.2–3.1 vs. 10–37 × 3–8 cm), leaf margins (shallowly repand and mucronulate vs. serrulate), and shorter bracteoles (1.2–4 vs. ca. 5 mm). Phylogenetic assessments based on two nuclear genes and three chloroplast genes indicated that P. youyangensis has a closer evolutionary relationship with P. yingdeensis but is differentiated from the latter by long stolons, smaller leaf blades (vs. 6.2–16.5 × 4–11.5 cm), leaf margins (vs. crenate-serrate), and notably shorter bracteoles (vs. 7–8 mm).

Diagnosis: The height and foliage dimensions of Paraphlomis youyangensis are similar to those of P. jiangyongensis and P. nana; however, its floral characteristics are more similar to those of P. kuankuoshuiensis. Despite these similarities, P. youyangensis is readily distinguishable from P. kuankuoshuiensis by several distinct traits: inconspicuous rhizomes (<0.5 vs. 2–4 cm), long stolons (vs. absent), much smaller sized lamina (1.8–5.5 × 1.2–3.1 cm vs. 10– 37 × 3‒8 cm), shallowly repand and mucronulate lamina margin (vs. serrulate), and shorter bracteoles (1.2–4 mm vs. ca. 5 mm).

Abstract

Thailand is the biodiversity hotspot of genus Kaempferia (Zingiberaceae) and harbours 14 species belonging to K. subgenus Protanthium. To better understand the taxonomic circumscription and verify the taxonomic status, the present characterization of cytogenetic characters included all recognized and one undescribed species of K. subg. Protanthium from Thailand. Overall, 88 accessions of plant materials were analysed cytogenetically: 84 and 42 accessions were subjected to flow cytometry and karyology, respectively. Based on genome size and mitotic chromosome numbers, 74 accessions from all species investigated were putative diploid, whereas the others were putative polyploid: triploid (three accessions) and tetraploid (11 accessions). The cytogenetic evidence indicates that 2n = 2x = 22 is the diploid number and x = 11 is the base chromosome number for K. subg. Protanthium. The genome sizes among the diploid accessions ranged from 3.687 to 6.412 pg while high intraspecific variation in genome size was observed with up to 19.4%. Two species included accessions with different ploidy levels: K. rotunda L. (diploid, triploid and tetraploid) and K. takensis Boonma & Seansouk (diploid and tetraploid). The increase in genome size of tetraploid K. rotunda is nearly in correlation to the increase in ploidy level, whereas the triploid plants represent genome expansion with an approximately 11% larger than expected genome. Interestingly, tetraploid K. takensis displays genome downsizing of 15.3% compared to their diploids. The cytogenetic characteristics, together with morphology, unequivocally clarify the taxonomic status of a new species, named Kaempferia calcicola Noppornch. A revised identification key to species of K. subg. Protanthium is provided.

Kaempferia calcicola Noppornch., sp. nov.  

Diagnosis — Kaempferia calcicola Noppornch. is similar to K. takensis Boonma & Seansouk in overall habit, inflorescence and floral plane, but differs by anther crest obreniform, broadly ovate, obovate to obdeltoid (vs anther crest oblong to ovate in K. takensis) with irregular undulate to crenate apex (vs bilobed to irregularly tridentate apex, usually with 2–3 small teeth between lobes in K. takensis) and labellum with an incision c. 3/5 of its length (vs labellum with an incision more than 2/3 of its length in K. takensis). It is also similar to K. lopburiensis Picheans. in inflorescence, floral plane and flower colour, but differs by prominent pseudostem upright above ground (vs pseudostem short and completely embedded in soil in K. lopburiensis), leaf blades elliptic, elliptic-oblong to lanceolate-oblong and longer petiole 3–18(–30) cm long (vs leaf blades suborbicular to ovate, adpressed on ground and subsessile petiole in K. lopburiensis).

Abstract

A new species of Polylepis (Rosaceae) from the Humid Puna of the Bosque de Proteccion Pui-Pui in Junin, Peru, is described and illustrated. The new species was found at 3800 m elevation, in small patches or forest relicts of the natural protected area, growing in open areas highly exposed to wind and abundant fog, along with other shrubby species, mainly Chusquea tessellata (Poaceae). It is very similar to Polylepis canoi but differs by trifoliolate leaves with larger leaflets, lanuginose abaxially, and rounded to ovoid achenes, smaller than those of P. canoi. We also present details on its geographic distribution, ecological notes, and an assessment of the conservation status of the new species.

Abstract

Saurauia decolorata from the Mt. Pantaron Range, Bukidnon and Mt. Balatukan Natural Park, Misamis Oriental, Mindanao Island, the Philippines, is illustrated and described as a new species. It closely resembles S. avellana and S. elegans in having branchlets, petioles, and abaxial surfaces of the leaves covered with tomentum and scales, densely clustered flowers, longitudinal anther dehiscence, and 3–4 styles. However, S. decolorata is distinguished from these species by its prominent rusty-colored tomentum and scales on branchlets and abaxial leaf surfaces, cordate leaf bases, crenate margin, 16–21 pairs of lateral veins, fascicled-cymose inflorescences that are both axillary and ramiflorous, and sparsely scaly pinkish green outer sepals. This discovery further emphasizes the unique biodiversity of the forests of the Pantaron Range and Mt. Balatukan which urgently need legislative protection and enhanced protected area management plans, respectively.

Abstract

A new species of Eriotheca (Bombacoideae, Malvaceae) from montane wet forests in the Atlantic Forest of Bahia, northeastern Brazil, is described and illustrated. It is known from only three populations situated between 750 m and 850 m in elevation on mountain summits and categorized as Endangered (EN) based on IUCN criteria. Eriotheca paganuccii is distinct from all congeners by the combination of coriaceous to strongly coriaceous leaves and remarkable few-seeded, globose to subglobose woody capsules that contain scanty kapok and the largest seeds known in the genus to date. The affinities of E. paganuccii to morphologically similar species as well as the importance of obtaining phenologically complete collections are discussed.

Key words: Bahian southern Atlantic Forest, ‘Bombacaceae’, ‘embiruçú’, endemism, plant taxonomy

 Eriotheca paganuccii Carv.-Sobr., A.C.Mota & Dorr, sp. nov.

 

Diagnosis: Similar to Eriotheca obcordata A.Robyns due to its absence of buttresses, obcordate leaflets, oblong to oblanceolate flower buds, oblanceolate petals, and stamens c. 80 in number, but differing in its caducous (vs. often persistent) bracteoles, larger calyces (7 × 7–9 mm vs. 5–5 mm), globose to subglobose (vs. obovoid) capsules, scanty (vs. abundant) kapok, seed number (c. 10 vs. numerous) per fruit, seed size (10–19 mm vs. 5–7 mm) long, and marcescent, lignified calyces that often split into patent lobes (in herbarium collections, at least).

Etymology: The specific epithet honors Luciano Paganucci de Queiroz, a distinguished Brazilian taxonomist who was the first to collect this new species and one of the first to promote and undertake floristic efforts on Serra da Jiboia, Bahia, its type-locality.

Abstract

Recent fieldwork conducted in Sumatra resulted in unusual collections of the conspicuous ginger genus Geocharis, a genus that harbours a total of six species distributed in Sumatra, the Malay Peninsula, Borneo and the Philippines. After carefully reviewing types and protologues of existing taxa, we conclude that the recent collections represent a new species described here as Geocharis globosa, which is similar to G. aurantiaca, G. rubra and G. radicalis by the flowers spreading evenly in all directions but differs from these by the less divided labellum and by the unstructured and smooth globose fruits. We provide a detailed description and a photographic plate as well as a preliminary Red List Assessment for the new species. With the new species added to Geocharis macrostemon and G. radicalis, the number of species in Sumatra hereby increases to three. A recircumscription of the genus is provided, taking into account the unusual fruit character of the new species.

Diagnosis: The new species is similar to G. aurantiaca, G. rubra and G. radicalis by the flowers spreading in all directions from an erect flowering shoot but differs from all of these by the labellum being incised only halfway from apex (not deeply or completely divided), and having a smooth and glabrous surface to the ovary and globose fruits (Table 2).

Etymology: The epithet refers to the shape of the fruit.

Abstract

Gentiana betongensis is described as a new species from Thailand. It was discovered in tropical montane sphagnum bog of the High Plateau in Betong District, Yala Province near the Thai-Malay Border. The new species is morphologically most similar to G. malayana in having erect, simple or few-branched stems, but differs markedly in having smaller flowers, triangular-ovate, acute corolla lobes, and long, recurved and coiled stigma lobes. This paper provides morphological description, illustration, photographs, distribution map, ecological data, reproductive biology, DNA barcode sequence, vernacular name, conservation status, a key to the species of Gentiana in Thailand, Peninsular Malaysia and Borneo, and a special note on conservation perspectives.
