Abstract

We describe Gehyra astrosyzygia sp. nov. from Phra Khayang Cave in Kraburi District, Ranong Province, southern Thailand. We report it from several other limestone formations in Chumphon, Phetchaburi, Prachuap Khiri Khan and Ranong provinces in Peninsular Thailand, and from the neighboring Tanintharyi Region in southern Myanmar. The new species differs from all currently recognized Southeast Asian Gehyra by the following combination of morphological characters and dorsal color pattern: maximal known snout–vent length of 56.9 mm, 7 or 8 supralabials, 80–83 dorsal and 44–48 ventral scale rows around midbody, absence of skin folds on limbs, 39–41 preanofemoral pores in males in a continuous series extending along the whole length of the femur (pores absent in females), tail not to moderately widened behind vent in adults, a single row of widened subcaudals, digits and toes with basal webbing, 7 or 8 divided subdigital lamellae on 4th toe, and a unique dorsal pattern with four paravertebral and lateral rows of large white round spots on a yellowish brown background, without dark spots or bars. We provide an osteological description of the cranium of the new species. The new species has been confused in online citizen science platforms with the rare, allopatric Gehyra angusticaudata, endemic to southeastern Thailand, for which we present new material and localities.

Abstract

Based on comparative chloroplast genomes (cp genomes) and phylogenetic analyses integrated with morphological evidence, this study investigated the taxonomic status and phylogenetic relationships of an extremely rare short-styled homostylous lineage of Primula from southwestern China, providing new molecular insights into the delimitation of this complex group. Complete cp genomes were sequenced and comparatively analyzed for one putative new taxon, Primula panzhouensis, and 15 representative samples within Sect. Petiolares from southwestern China. The cp genome characteristics, simple sequence repeat (SSR) patterns, codon usage bias, inverted repeat (IR) boundary variations, and nucleotide diversity patterns were systematically evaluated. Maximum likelihood (ML) and Bayesian inference (BI) analyses were conducted based on complete cp genome sequences, and an integrative taxonomic assessment was performed by combining cp genomic evidence with morphological comparisons. All 16 cp genomes exhibited a typical quadripartite structure, with genome sizes ranging from 151,076 to 153,420 bp. The overall cp genome structure and gene composition were highly conserved, although interspecific variations were detected in IR boundary regions, SSR distributions, and highly variable regions, including trnH-psbA and ycf1. The sequenced cp genome of P. panzhouensis exhibited several distinctive structural features and sequence variation patterns compared with closely related taxa. ML and BI analyses consistently recovered P. panzhouensis as a distinct cp lineage within Sect. Petiolares with strong support. Morphological comparisons further demonstrated that P. panzhouensis possesses the short-styled homostyly trait and can be distinguished from related taxa by differences in floral style structure, corolla morphology, scape length, and leaf characteristics. Integrating cp genomic evidence, phylogenetic relationships, and morphological traits, our results support the recognition of P. panzhouensis as a distinct taxonomic entity, which is herein described as a new species, Primula panzhouensis Z.K.Wu, sp. nov. This study demonstrates that comparative cp genomics integrated with phylogenetic analyses can effectively assist in resolving lineage relationships and taxonomic boundaries in complex groups of Primula. It also identifies an extremely rare short-styled homostylous species, providing valuable material for further investigating the evolution of floral diversity and its potential evolutionary significance in Primula.

Keywords: chloroplast genomics, molecular phylogeny, morphological taxonomy, Primula panzhouensis, Primula sect. Petiolares, short-styled homostylous species

Primula panzhouensis Z.K.Wu, sp. nov.

 Diagnosis: The new species is morphologically similar to P. esquirolii, P. bergenioides, and P. hookeri, and all four species exhibit morphological characteristics consistent with the diagnostic features of Sect. Petiolares. It differs from P. esquirolii primarily in that the latter produces few or no new leaves during the flowering period, has a relatively long corolla tube, and bears extremely shortened scapes that are usually less than 1 cm in height or nearly absent. In addition, P. esquirolii is homostylous with long-style flowers, whereas the new species possesses a short corolla tube, well-developed scapes, and produces numerous new leaves during anthesis. Compared with the heterostylous P. bergenioides, the new species is readily ...

  Etymology: The specific epithet of the new species is taken from the Chinese Pinyin “Panzhou”, the name of the county in western Guizhou, China, where the type specimen was collected (Figure 15).

Abstract

We describe a new species of karst-associated Cyrtodactylus Gray, 1827 (Gekkonidae) of the khasiensis species group within the Indo-Burma clade from Umrangso, Dima Hasao District, Assam, northeast India, based on integrative analysis with morphological and molecular data. The new species Cyrtodactylus dimaensis sp. nov. is revealed as a sister taxon to the recently described C. vanarakshaka, both belonging to the same district, Dima Hasao, Assam, with an uncorrected p-distance of 5%, and to C. namtiram of Manipur with 10% divergence. Intraspecific uncorrected p-distance for the new species was found to be between 0.0–1.3 %, and the interspecific divergence from the closely related congeners was between 5–38 %. The new species can be identified from its congeners by the presence of 7 or 8 precloacal pores in subadult males. This is the eight Cyrtodactylus species described from Assam, highlighting the region’s richness in herpetofaunal diversity and the need for further herpetological expeditions into this highly under-studied region.

Abstract

A new luminescent lignicolous fungal species, Mycena cristinae sp. nov., is proposed from the Central Amazon forest. This is unique and supported by morphological evaluation along with LSU- and ITS-based phylogenetic analyses. The basidiomata have mostly fuscous olivaceous brown pileus, adnate to subdecurrent and distant lamellae, and stipe with slightly bulbous base (basal mycelium absent). It also has inamyloid and/or weakly amyloid basidiospores, ramose cheilocystidia and a pileipellis composed of an aerated tangle of slender, diverticulate hyphae forming a coralloid pellicle overlaying the hypodermium. The luminescence is evident in the basidiomata (especially the stipe) and in the mycelium on the substrate. The LSU phylogenetic trees reveal that M. cristinae is sister to M. coralliformis within the Mycenaceae clade. In the ITS trees, it forms a unique lineage grouping with undetermined Mycena taxa. Morphological data support M. cristinae as a different species compared to previously described taxa.

Abstract

Four new species of Collybiopsis, namely C. subpolygramma, C. fucata, C. dentata, and C. latispora, were discovered in the subtropical regions of China. These species were identified based on morphological characteristics and molecular analysis. Morphologically, C. subpolygramma is characterized by its pileal surface, white in color with a light brown center; slender, cylindrical cheilocystidia; and absence of pleurocystidia. C. fucata is recognized by the reddish-brown, hygrophanous pileus; adnate to adnexed lamellae; and relatively broad basidiospores. C. dentata is identified by free lamellae, fusiform to utriform pleurocystidia, and relatively broad basidiospores. C. latispora is distinct by relatively broad basidiospores and a minute, snow-white ring or ruff at the stipe base. In the phylogenetic analysis based on combined ITS and LSU sequences, the four new species formed distinct and stable branches (BI-PP = 1; ML-BP = 100%), respectively. Collybiopsis subpolygramma formed a sister lineage with C. polygramma. The new species C. fucata, C. dentata, and C. latispora were found to be nested within the C. ramealis species complex clade. Detailed descriptions, color photos, and a key to related species are presented.

Abstract

An overlooked species of the mountain pitviper genus Ovophis Burger in Hoge and Romano-Hoge, 1981, is described from the highlands of central Vietnam and southern Laos based on an integrative taxonomic approach combining molecular and morphological evidence. Ovophis orlovi sp. nov. has long been confused with O. monticola and, less frequently, O. convictus, but is recovered as a distinct and well-supported evolutionary lineage in mitochondrial phylogenetic analyses, forming the sister taxon to O. anitae. Its distinctiveness is further supported by substantial mitochondrial divergence from its closest relative (cyt b uncorrected p-distance = 8.0%) and by a unique combination of diagnostic morphological characters, including body proportions, scalation, and color pattern. Ovophis orlovi sp. nov. is currently known from montane evergreen forests of the Kon Tum-Gia Lai Plateau in central Vietnam and adjacent montane areas of southern Laos at elevations of approximately 900 – 1,400 m a.s.l. The recognition of Ovophis orlovi sp. nov. resolves a long-standing taxonomic misidentification involving populations previously referred to O. monticola or O. convictus, further demonstrates that species diversity within Ovophis remains underestimated, and highlights the importance of integrative taxonomic studies for uncovering overlooked diversity in the montane regions of mainland Southeast Asia.

Abstract

A new species of Calamaria is described from the Tenasserim Range, Ratchaburi Province, western Thailand based on morphological and molecular evidence. Calamaria flavicollaris sp. nov. can be distinguished from its congeners by the combination of the following morphological characters: 1) rostral scale wider than high; 2) portion of rostral scale visible from above greater than the half the length of the prefrontal suture; 3) prefrontal length shorter than frontal length, not entering orbit and in contact with first two supralabials; 4) five or six scales surrounding paraparietal scale; 5) preocular and postocular present; 6) four supralabials, the second and third in contact with the eyes; 7) eye diameter smaller than eye-mouth distance; 8) five infralabials, the first pair separating the mental scale from anterior chin shields; 9) seven modified maxillary teeth; 10) 180 ventral scales with three preventral scales; 11) 13 divided subcaudal scales; 12) cloacal plate single; 13) tail relatively short (4.5% of the total length), tapering, gradually to a pointed tail tip; 14) dorsum dark brown with eleven dark longitudinal stripes; 15) ventral surface yellow with a median line of dark flecks on underside of tail; and 16) dark collar followed by yellow ring at nuchal region. Genetically, the new species exhibits a pairwise distance of ≥17.56% from all other congeners based on the mitochondrial cytochrome b gene fragment. Furthermore, we provide cranial osteological description of the new species based on micro-CT scanning. Calamaria flavicollaris sp. nov. is currently known only from the type locality and represents the fourth species of the genus recorded for Thailand.

Calamaria flavicollaris sp. nov.

Diagnosis. Calamaria flavicollaris sp. nov. can be distinguished from all other congeners by the following combination of characters (Tables 3, 4; Suppl. Table 1): 1) rostral scale wider than high; 2) portion of rostral scale visible from above greater than the half the length of the prefrontal suture; 3) prefrontal length shorter than frontal length, not entering orbit, and in contact first two supralabials; 4) five or six scales surrounding the paraparietal scale; 5) preocular and postocular present; 6) four supralabials, the second and third in contact the eyes; 7) eye diameter smaller than eye-mouth distance; 8) five infralabials, the first pair separating the mental scale from anterior chin shields; 9) seven modified maxillary teeth; 10) 180 ventral scales with three preventral scales; 11) 13 divided subcaudal scales; 12) cloacal plate single; 13) tail relatively short (4.5% of the total length), tapering, gradually to a pointed tail tip; 14) dorsum dark brown with eleven dark longitudinal stripes; 15) ventral surface yellow with a median line of dark flecks on underside of tail; and 16) a dark nuchal collar followed by a yellow ring along neck.

Four Calamaria species in Thailand:
A Calamaria flavicollaris sp. nov. from Suan Phueng District, Ratchaburi Province B C. lumbricoidea from Than To District, Yala Province
C C. schlegeli from Betong District, Yala Province D C. pavimentata from Kaeng Hang Maeo District, Chanthaburi Province

Etymology. The specific epithet flavicollaris is derived from the Latin words “flavo” (yellow), “collare” (collar or neck), and the suffix “-aris”, which refers to the appearance of the yellow nuchal ring of this species. 

We suggested an English common name “Tenasserim Collared Reed Snake” and the Thai common name “งูพงอ้อบ่วงบาศ” (Ngu Phong O Buang Bat) for this species.

Abstract

A taxonomic study of the genus Bolbitius from northeast China was conducted, based on morphological observations and molecular phylogenetic analyses. Phylogenetic relationships were reconstructed, based on a combined multi-locus dataset comprising the internal transcribed spacer (ITS), nuclear large subunit (nrLSU) and translation elongation factor 1-α (tef1-α) sequences. As a result, two new species are described and illustrated: Bolbitius planoflavus, characterised by its distinctly applanate, pale yellow pileus when mature and the presence of occasional 2-spored basidia; and Bolbitius fuscopapillatus, distinguished by its violet-brown papillate umbo and purplish-white margin bearing faint veil remnants. Additionally, Bolbitius bisporus is reported as a new record for China. Detailed morphological descriptions, colour photographs and comparisons with closely-related taxa are provided.

Abstract

Background and Aims: In Mexico, Annona is among the most species-rich genera of the family Annonaceae, with 18 currently recorded species. As part of our ongoing revision of the genus in Mexico, we examined specimens from western Mexico that correspond to a previously undescribed species, which is described and illustrated here.

Methods: The new species was recognized based on the unique combination of morphological features, through comparisons with similar species and a thorough review of the literature. Its conservation status was assessed by calculating its Extent of Occurrence (EOO) and Area of Occupancy (AOO), using the GeoCAT tool and following the IUCN Red List Categories and Criteria.

Key results: A new Annona species, Annona breviflora, endemic to western Mexico, is described and illustrated. Based on the criteria established by the IUCN, the species can be provisionally assessed as Endangered (EN B2 ab (i, ii, iii, iv)).

Conclusions: The most similar species to Annona breviflora is A. globiflora, with which it shares small flowers bearing three petals and small leaves that are longer than wide, with 6-10 secondary veins per side. However, A. globiflora occurs in eastern Mexico and exhibits morphological characteristics, such as nearly sessile flowers and glabrous leaves, that clearly distinguish it from A. breviflora.

Annona breviflora Ortíz-Rodr., Hurt.-Rev. & Amancio, sp. nov.

Annona breviflora is morphologically similar to Annona globiflora in the small flowers with three petals, and flower buds pyramidal to globose. However, it is dis-tinguished from it by its broader leaves, 2.5-5 cm wide, sparsely to densely covered with adpressed to ascending hairs below (vs. 1-3 cm wide, glabrous below), and by its longer floral pedicels up to 30 mm long (vs. flowers almost sessile, pedicel up to 3 mm long).

Etymology: the species epithet “breviflora” (from Latin brevis, short) refers to the small size of its flowers, petals and buds.

Abstract

A new genus and species of an early-diverging hadrosauroid dinosaur, Paludohadros proudlovii gen. et sp. nov., is described from the Lower Cretaceous Weald Clay Formation of Smokejacks Brickworks, southern England. This new taxon can be diagnosed by the following autapomorphies and combination of characters: dentary teeth with two secondary ridges and a variable number of accessory ridges on the lingual surface of the crown; surangular with a dorsally projecting lateral process that is offset laterally from the dorsal surface of the anterior process; humerus with a proximally extending ridge on the anteromedial surface of the distal condyle; ischium with a posteroventrally curved shaft, a well-developed ischial boot and an obliquely oriented crest dorsal to the obturator process on the lateral surface of the shaft and a tibia with bosses on the medial and lateral surfaces near the proximal end. Although iguanodontians from the Weald Sub-basin have long been known from older Valanginian strata, represented by Barilium dawsoni, Hypselospinus fittoni and Kukufeldia tilgatensis, the description of Paludohadros proudlovii from the Barremian represents an increase in this diversity of iguanodontians from the Wealden Group, and it is the only valid iguanodontian taxon from the Barremian Weald Clay Formation reported so far. Although broadly contemporaneous, the iguanodontians of the Wessex Formation of the Isle of Wight are different taxa, raising the possibility that the Wessex and Weald Clay formations were deposited at slightly different times.

Paludohadros gen. nov.

Etymology. Paludohadros is derived from the Latin word palus (genitive paludis), meaning swamp, reflecting the swampy environment of the Weald Clay Formation during the Early Cretaceous, and that Smokejacks Pit is often very muddy today, and the Greek word hadros, meaning robust or stout, a term frequently used for iguanodontians.

Locality and horizon. UK National Grid Reference TQ 11252 37263 (± 6 m), Smokejacks Pit (also known as Ewhurst Works, and sometimes referred to as Ockley Pit), Ockley, Surrey, UK. Weald Clay Formation, Barremian, Lower Cretaceous. The specimen was found in the same horizon but about 100 m west of the Baryonyx walkeri type locality.

Paludohadros proudlovii gen. et sp. nov.

Etymology. The specific name honours the late Mr William Proudlove, former factory manager of Ewhurst Works. Will passed away in 2000 at the age of 35, shortly before the specimen was excavated, leaving behind a young family. He was an important coach and mentor to current manager Tim Burgess, and we name the specimen in his memory here.

Holotype. NHMUK PV R 16396, a partial skeleton ....

 

Diagnosis. Paludohadros proudlovii differs from all other iguanodontians by possessing the following autapomorphies and a unique combination of characters (autapomorphies indicated with an asterisk): dentary teeth with two secondary ridges and a variable number of accessory ridges on the lingual surface of the crown (1); surangular with a dorsally projecting lateral process that is laterally offset from the dorsal margin of the anterior process and separated from it by a shallow groove* (2); humerus with a proximally extending ridge on the anteromedial surface of the medial distal condyle (3); ischium with a combination of a posteroventrally curved shaft, a well-developed ischial boot and a laterally projecting crest on the lateral surface on the proximal portion of the shaft* (4); tibia with a boss on the medial surface of the proximal end (5).
