Abstract

A new species of mountain horned dragon, Acanthosaura syrax sp. nov., is described from the high–elevation evergreen forests of Mae Wong National Park in western Thailand. Morphological comparisons distinguish the new taxon from its congeners by its smaller body size and the fact that it possesses the smallest nuchal and dorsal scales recorded within the genus. Phylogenetic analysis of mitochondrial ND2 and COI gene sequences further supports this distinction, identifying the new species as a reciprocal monophyletic lineage with 76% and 99% nodal support in maximum–likelihood analyses and 0.78 and 1.00 nodal support in Bayesian Inference analyses based on ND2 and COI genes, respectively. Interspecific pairwise genetic distances between A. syrax sp. nov. and other congeners range from 14.1–15.9% in ND2 gene and 14.96–28.13% in COI gene, while intraspecific variation remains low at 0–0.01% and 0–0.34% in ND2 and COI, respectively. This discovery brings the number of Acanthosaura species to 23 and highlights the significant and unique biodiversity found within the high–altitude evergreen ecosystems of western Thailand.

Etymology. The specific epithet syrax is a noun in apposition, named in reference to the dragon “Syrax”, the mount of Queen Rhaenyra Targaryen [from George R.R. Martin’s A Song of Ice and Fire universe]. This name is inspired by the species’ distinctive yellow-hued coloration, its relatively diminutive size compared to its congeners, and its significant reproductive output, reflected in its high clutch size. We suggest the following common names, “Syrax mountain horned dragon” (English) and “King Ka Khaow Naam Lek Syrax” (กิ้งก่าเขาหนามเล็กไซแรกซ์) (Thai).

Abstract

A new genus and species of fossil isopod, Cicero spectabilis n. gen. n. sp. is described from the Early Cretaceous (Aptian) Nova Olinda Member of the Crato Formation, Araripe Sedimentary Basin, Ceará, northeastern Brazil. The holotype, preserved in laminated limestones, represents the first confirmed record of the family Archaeoniscidae within this stratigraphic unit and extends the previously known paleogeographic distribution of archaeoniscid-like isopods into Gondwana lacustrine settings. The new genus is distinguished from other taxa currently referred to Archaeoniscidae—Archaeoniscus, Ferreniscus and Codoisopus, by its broad, ovate body, distinctive antennular subdivision, and a fan-like caudal structure formed by birramous uropods with well-differentiated exopod and endopod, combined with a rounded subrectangular pleotelson bearing a row of posterior setae. The exceptional preservation of C. spectabilis n. gen. n. sp. enables a detailed assessment of functionally relevant characters and supports interpretation of a benthic lifestyle on soft, low-energy substrates. A conservative concept of the family and a combination of body, pleon-pleotelson and antennular features justifies the placement of Cicero n. gen. within this extinct sphaeromatidean lineage. Within this framework, the occurrence C. spectabilis n. gen. n. sp. in a stratified lacustrine system of the Araripe Basin, together with other Mesozoic archaeoniscid-like records, suggest that some lineages currently assigned to Archaeoniscidae were able to colonize a range of non-marine environments during the Early Cretaceous, while also underscoring the need for a comprehensive phylogenetic reassessment of the group.

Abstract

The evolution of insect sensory and signalling systems has played a key role in arthropod diversification, yet direct fossil evidence illuminating their early history remains rare. Lampyroids, including fireflies and their relatives, are notable for their elaborately modified antennae and bioluminescence. These characteristics make them an exceptional model for understanding the coevolution of sensory and signalling modalities. Here we describe Icaroramus perisi gen. et sp. nov. from mid-Cretaceous Kachin amber, a lampyroid beetle tentatively placed within Cretophengodidae. Icaroramus is exceptional in possessing both extraordinarily elaborate antennae and a well-developed photic organ. Its 12-segmented quadriheteroramose antennae represent an antennal architecture unknown among extant and fossil beetles. Functionally, these antennae likely combined an expanded olfactory surface area with differentiated sensory fields, enhancing the detection of pheromonal cues. Mate location was therefore probably mediated primarily by pheromones, whereas bioluminescence may have retained its plesiomorphic role in aposematic defence. This discovery expands the known morphological and ecological diversity of Cretaceous lampyroids and provides new insight into the origins of complex signalling strategies in fireflies and their relatives.

Genus Icaroramus Li, Kundrata & Cai gen. nov.

 

Diagnosis. Antennae 12-segmented; antennomeres 4–11 quadriheteroramose, each with two morphologically different pairs of rami (figures 1C, 2A–C) (antennomeres 4–11 biramose in Cretophengodes Li et al.). Pronotum with posterior angles acute and shortly produced posteriorly (figure 1A) (posterior pronotal angles obtuse in Cretophengodes). Prosternum in front of coxae longer than longitudinal diameter of procoxal cavity; prosternal process extending well beyond procoxae and fitting into mesoventral cavity (figure 2D). Mesoventral cavity well developed (figure 2E). Abdomen with six ventrites; ventrite 6 with entire surface luminous (figure 1B) (possible luminous organ present on medial portions of abdominal ventrites 1–3 in Cretophengodes).

Etymology. The generic name is formed from Icarus, the mythological figure who flew too close to the Sun and fell into the sea, and ramus, referring to the multiple long rami on each antennomere. It metaphorically evokes an evolutionary ‘overreach’, a unique antennal elaboration that was lost and not inherited by extant lineages. The name is masculine in gender.

Abstract

A new species of the genus Brachytarsophrys is described from Guangxi Zhuang Autonomous Region, China. The new species can be distinguished from its congeners by a combination of morphological characters: body size relatively small, dorsal skin smooth with a few large tubercles on dorsum and crotch, snout relatively long, eye relatively small, foot relatively short, pectoral glands orange, upper iris blood red and lower iris reddish brown, nuptial pad present on first finger in adult male. Phylogenetically, the new species differs from other species of the genus by a genetic divergence of 4.2–15.7% and 3.3–15.2% in COI and cytb genes, respectively. This study brings the total number of the species of Brachytarsophrys to 12, with ten occur in China and three in Guangxi.

Abstract

Meiogyne monogyna (Merr.) Bân was previously treated as conspecific with the widespread M. virgata (Blume) Miq. and was synonymized under the latter. However, based on detailed examinations of herbarium specimens and field observations of living plants, we confirm that M. monogyna is a morphologically distinct species. Consequently, we reinstate its species status and document it as a new record for the flora of China, providing a comprehensive taxonomic description and including it in an updated identification key for all three species of Meiogyne recorded in China.

Abstract

Archosauromorpha is a dominant reptile clade that primarily occupied terrestrial ecosystems with limited secondarily aquatic invasions that are poorly known. Here we report on a well-preserved Triassic reptile representing the earliest stem-archosaur to evolve unequivocal aquatic specializations. This taxon exhibits a suite of aquatic adaptations previously unknown in stem-archosaurs, such as hyperphalangy, enhanced paddle-like forelimbs, and a loss of articulation between the sacrum and pelvis, indicating an advanced aquatic lifestyle. The fossil exhibits the oldest known stomach, liver, and intestinal preservations in reptiles. Our findings provide unexpected insights into the early aquatic diversification of Archosauromorpha during the Triassic marine ecosystem recovery and highlight a conservative gastrointestinal system in an early Mesozoic vertebrate. In the absence of clear terrestrial members of the other major Mesozoic marine reptile lineages (e.g., ichthyosaurs and sauropterygians), this discovery provides an unambiguous example of such a lineage including both decidedly terrestrial and extensively marine forms, providing tantalizing evidence for the land-to-sea transition in Triassic reptiles.

Meiogyne Miquel (1865: 12; Annonaceae), with 33–39 species, are trees or shrubs characterised by distinctive corrugated grooved structure at the base of the adaxial surface of the inner petals, axillary or sometimes cauliflorous flowers and oblong multi-seeded indehiscent monocarps (van Heusden 1994, Johnson et al. 2019, Jaikhamseub et al. 2022). The species are collectively distributed in southern India, southern Central China, Southeast Asia, Australia, Melanesia and western Polynesia (van Heusden 1994, Thomas et al. 2012, POWO 2024). In Vietnam, six species of Meiogyne are known (Bân 2000, Jaikhamseub et al. 2022): M. monogyna (Merrill 1942: 163) Bân (1974: 1778), M. subsessilis (Ast 1938: 90) Sinclair (1956: 14), M. hainanensis (Merrill 1925: 131) Bân (1973: 1148), M. rubra Jaikhamseub, Damth. & Chaowasku in Jaikhamseub et al. (2022: 223), M. virgata (Blume 1825: 14) Miquel (1865: 12) and M. vietnamica Jaikhamseub, T.A.Le & Chaowasku in Jaikhamseub et al. (2022: 225), although Jaikhamseub et al. (2022) excluded M. virgata because they could not confirm any Vietnamese specimens. 

During our botanical expedition in Kon Ka Kinh National Park, Gia Lai Province, Central Highland, Vietnam, in 2022, we encountered an unknown species of Meiogyne in primary broad-leaved evergreen forests. After a careful examination of the literature of the genus in Vietnam and surrounding countries (Ast 1938, Bân 2000, van Heusden 1994, Johnson et al. 2019, Jaikhamseub et al. 2022) and herbarium specimens including digitised images from FOF, FU, HN, K, KAG, MAK, P and VNM, we concluded that it was an undescribed species, and we here describe it as new to science.

 Abstract  

One challenge for species delimitation involves closely related species, characterized by both intra- and interspecifically variable morphologies, for which genetic information is not yet available. One such example is exhibited by agamid lizards of the genus Bronchocela. This group of conspicuously vibrant green lizards is widely distributed in Southeast Asia, with 15 recognized species. However, the geographic distributions of several named taxa have remained unclear because of the imprecise application of names in taxonomic summaries and faunal checklists. For more than a century, many authors have noted that a few species, often considered “widespread,” persist throughout nearly the entire range of the genus. This is particularly true for populations identified as Bronchocela cristatella sensu lato and, to a lesser extent, B. marmorata in the Philippines. In this study, we reassess the systematics and taxonomy of Bronchocela populations in the Philippine archipelago. Using multiple lines of evidence from molecular and morphological data, we uncover four distinct lineages of Philippine Bronchocela, all of which we interpret as being distantly related to B. cristatella sensu lato from Malaysia and Indonesia. We argue that these lineages should now be interpreted as Philippine endemic species. Given the strong congruence in molecular and morphological analyses, we now consider populations from the Luzon faunal region (including Catanduanes, Marinduque, Lubang, and Polillo Islands), Romblon (Tablas, Romblon, and Sibuyan Islands), and the West Visayas (Negros, Cebu, and Panay Islands) as B. marmorata. The nomenclaturally available name, B. philippina, is now designated to the unique lineage from the Mindanao faunal region. Additionally, we recognize two new, distinctive species from the Mindoro (B. carestiai) and Palawan (B. mallarii) faunal regions. Overall, our findings demonstrate how conspicuous and widely distributed species in Southeast Asia remain poorly understood, overlooked, and taxonomically unresolved. Hence, the taxonomic resolution of Bronchocela populations in the island archipelagos of Southeast Asia will greatly benefit from the urgent priority of determining which landmass the name “B. cristatella” applies.

This is the fourth genus and fourth described species of Pedunculinae and the second from the Neotropics. Each of the four known genera is defined by putative apomorphies, included in an identification key, and photos of each are provided.

KEYWORDS: Austral, Darwin wasps, Gondwanan, new species, South America, taxonomy, Sir David Attenborough

Attenboroughnculus De Ketelaere and Broad, gen. n.

  

Etymology: 

This unique genus from Chile has been named after Sir David Attenborough ahead of his 100th birthday, celebrating the broadcaster and biologist’s highly distinctive contribution to our understanding of the natural world. David Attenborough has featured Chile’s diverse, extreme landscapes in several documentaries, emphasising the unique environmental challenges and ecological resilience of species within the country.

Sir David has also filmed several scenes with parasitoid wasps, famously termed the ‘bodysnatcher wasp’ by the broadcaster in the Trials of Life, first broadcast in 1990. He has used his work to reveal the intimate, unseen or overlooked within nature. This resonates in the discovery of this species in an unsorted drawer within the collections of the Natural History Museum, London.

In 2023 Sir David revealed a new bronze quote outside the Natural History Museum, London, reading: The future of the natural world, on which we all depend, is in our hands. We are using this opportunity to echo this message through the naming of this new genus of tiny wasp.

We hope to inspire global scientists to take another look in their collections to see if there is something small that could contribute to our collective understanding and therefore the future of our natural world. The name is a concatenation of ‘Attenborough’ and ‘Pedunculus’.

Attenboroughnculus tau De Ketelaere and Broad, sp. n.

Etymology: Named after the large, capital ‘T’ marking on the second metasomal tergite, with ‘tau’ being the Greek for ‘T’. A noun in apposition.

Abstract

Ophiorrhiza saxatilis M.T.An & G.L.Li, sp. nov., a new species of the genus Ophiorrhiza (Rubiaceae) discovered in the karst regions of Guizhou, China, and provides its taxonomic basis from a morphological perspective. The new species is morphologically similar to Ophiorrhiza lignosa, but differs from the latter by having an inflorescence in that its young branches are uniformly pubescent (vs. bifariously pubescent in O. lignosa); the abaxial leaf surface is pubescent (vs. puberulent only along the midrib and secondary veins in O. lignosa); the bracteoles are 5–6 mm long (vs. 1.5–3 mm long in O. lignosa); the petioles are 2–5.8 mm long (vs. 6–20 mm long in O. lignosa); the stamens are inserted at the base of the corolla tube (vs. inserted near the middle of the corolla tube in O. lignosa); the flowers are distylous (vs. monomorphic with pin flowers in O. lignosa), and the styles of long-styled flowers are 6–8 mm long (vs. 10–11 mm long in O. lignosa). These stable and significant morphological differences, combined with a comprehensive and detailed morphological description of the new species and a comparison of diagnostic characters with similar species, firmly support the recognition of Ophiorrhiza saxatilis as a distinct new species.

Ophiorrhiza saxatilis M.T.An & G.L.Li, sp. nov.

Diagnosis. Ophiorrhiza saxatilis is morphologically similar to O. lignosa Merr., but can be distinguished by several key characteristics (Table 2): uniformly pubescent young branches (vs. bifariously pubescent); white corolla lobes with ridges (vs. purple, without ridges); stamens inserted at the base of the corolla tube (vs. inserted near the middle of the corolla tube); flowers distylous (vs. monomorphic, with pin flowers); long-styled flowers 6–8 mm long (vs. 10–11 mm long); purple midrib on the abaxial leaf surface (vs. green); abaxial leaf surface pubescent (vs. puberulent only on the midrib and secondary veins); bracteoles 5–6 mm long (vs. 1.5–3 mm long); and petioles 2–5.8 mm long (vs. 6–20 mm long).

Etymology. The specific epithet is derived from the habitat of the new species, which occurs in a typical karst limestone environment. It mainly grows in harsh habitats such as rock crevices and stony slopes.

Abstract

As currently defined, Pristimantis subsigillatus is a species of the P. lacrimosus species group distributed in the Chocó of Colombia and Ecuador, from lowlands to Andean foothill forests. Upon re-examination of the holotype of P. subsigillatus, we conclude that the populations currently ascribed to P. subsigillatus are not conspecific with the holotype. Instead, the holotype is conspecific with one of the syntypes of P. latidiscus, a species described four years before from a nearby locality. To avoid the ambiguity in the application of the binomen Hylodes latidiscus, we designate a lectotype. As a result, P. subsigillatus becomes a junior synonym of P. latidiscus. The misidentified populations represent an undescribed species which we describe based on morphological, bioacoustic, and genetic data as Pristimantis milpe sp. nov. The new species has one of the widest distributions among Chocoan Pristimantis and is unusual for having sexual dimorphism in coloration. It is most closely related to Pristimantis degener from which it diverged in the late Miocene and is morphologically distinct. The fact that such a common species remained “invisible” to taxonomy highlights the importance of correctly establishing the link between the name-bearing types and natural populations. Finally, we discuss how taxonomic treatments of Pristimantis during the second half of the 20th century often made this non-trivial error.

Etymology. The specific epithet is a noun in apposition and refers to the type locality, the Milpe Bird Sanctuary, a private reserve in Pichincha Province, Ecuador. The sanctuary protects ~ 100 ha of Foothill Montane Forest and is part of the Andean Chocó, one of the most diverse and threatened regions on the planet. The Milpe Bird Sanctuary is managed by the Mindo Cloudforest Foundation, a non-profit organization dedicated to the conservation of biodiversity in the Andean Chocó. The Foundation maintains close relationships with local communities, promoting environmental education, sustainable livelihoods, and participatory management of natural resources. It also supports other private reserves and local Decentralized Autonomous Governments in forest restoration through the production of native plants in their nurseries, strengthening long-term conservation in the region.
