Summary

Nepenthes siamensis, a new species from Khlong Phanom National Park in southern Thailand, is described. This species, closely related to others in section Montanae, stands out due to its distinct inflorescence characteristics, including bracts present on both male and female flowers, and unique pitcher morphology. It is found approximately 650 km north of the most similar species based on morphological comparison, N. sanguinea and N. thai, which are also both terrestrial and lower montane. It shares characters with them, such as a climbing habit and oblong to subspathulate leaves with 2 – 3 longitudinal nerves on each side of the midrib. This discovery significantly extends the known range of section Montanae.

Abstract

A new species of dibamid lizard, Dibamus irregularis sp. nov. is described based on molecular (three mitochondrial genes) and morphological (external and skeletal) characters of twelve specimens collected from the Chu Yang Sin National Park, Dak Lak Province, southern Vietnam. The new species can be distinguished from other congeners by the following combination of characters: medial rostral suture absent or incomplete, nasal sutures incomplete, labial sutures complete or incomplete; two to three postoculars; three to four scales on the posterior edge of infralabial; 22–24 midbody scale rows; 180–211 ventral scales; 39–46 subcaudal scales; and maximum snout-vent length 147 mm. Moreover, two eggs of a new species were collected in the same locality. The only known clutch of Dibamus was described more than 120 years ago based on a single egg of D. alfredi collected from Bukit Besar, Thailand. Herein, we provide the first description of a complete clutch of the genus Dibamus based on two eggs of Dibamus irregularis sp. nov. Our study brings the total number of species in the genus Dibamus to 30; Dibamus irregularis sp. nov. is the 10th species of Dibamus recorded from Vietnam, highlighting the importance of the country as a hot spot of reptilian diversity in Southeast Asia.

Etymology. the new species epithet is a latin adjective in nominative singular, meaning “irregular,” andis given in reference to the high intraspecific variability of external morphological features in the new species,especially to the irregularity and asymmetry of the number of postocular scales (Fig. 6). Since Allen greer’s revision(greer 1985) and in all subsequent papers describing new species of Dibamus, the number of postocular scales wasconsidered as a relatively stable diagnostic character underlying diagnoses for new species of dibamids, which in partcould be explained by generally small sample sizes of Dibamus spp. available for examination. however, Dibamus irregularis sp. nov. demonstrates an unexpectedly irregular and asymmetrical number of postocular scales: fivespecimens have two postoculars, four specimens have three postoculars, and three specimens have two postocularson the left side and three on the right side of the head.

Abstract

Tessmannia princeps, a new canopy emergent rainforest tree species from the Udzungwa Mountains, Tanzania, is described and illustrated. It is a montane, unarmed tree distinguished by its large stature, extensively buttressed bole, and high number of leaflets. Tessmannia princeps shows morphological affinities with another Tanzanian species, T. densiflora, nevertheless the two species can be distinguished by morphological characters as well as by ecology and geography. A diagnostic key to the East African species of Tessmannia is provided. Due to its restricted range and small number of recorded mature individuals, the conservation status of T. princeps is assessed as Vulnerable under the IUCN criteria.

ABSTRACT

Pachycephalosaurian dinosaurs are represented in the fossil record primarily by their taphonomically resistant frontoparietal domes that developed fully only at maturity. Consequently, the postcranial record of Pachycephalosauria is poor, particularly for immature forms. Here, we describe the ontogenetically youngest known, and Canada’s second-most complete, pachycephalosaur postcranium, collected from the uppermost Maastrichtian Frenchman Formation, Saskatchewan. Despite its small size (estimated total length ∼90 cm), the skeleton shows several characters diagnostic of Pachycephalosauria, including a double ridge-and-groove articulation on the pre- and postzygapophyses of the dorsal neural arches, a medial flange on the postacetabular process of the ilium, and a highly reduced pubis that contributes only minimally to the acetabular margin. Histological sectioning of the crural bones shows an immature woven bone texture. The absence of cyclical or annual growth indicators suggests that this specimen was less than a year old at the time of death. Phylogenetic analysis recovers the specimen as a member of Pachycephalosaurinae, perhaps related to Prenocephale, but the lack of cranial data for our specimen and the complementary lack of postcranial data for other pachycephalosaurs make this determination tenuous. Spatiotemporal considerations suggest a possible but currently untestable affiliation with Sphaerotholus buchholtzae. The relatively long hindlimbs of the juvenile compared with those of adult pachycephalosaurs indicate probable negative ontogenetic allometry in the hindlimbs.

Abstract

A new species of the Cyrtodactylus intermedius group, Cyrtodactylus kiriromensis sp. nov., from Kirirom National Park of Phnom Sruoch in the Cardamom Mountains of Cambodia is delimited based on a mitochondrial (ND2) phylogeny and statistically diagnosed using meristic, morphometric, and color pattern characters. Cyrtodacytylus kiriromensis sp. nov. is the sister species of C. septimontium of southern Vietnam and forms part of a clade with six other site-specific endemic species from the mountains and islands of southeastern Cambodia and southwestern Vietnam. The ongoing discoveries of localized endemic species in the Cardamom Mountains underscores their fragmented nature and the importance of this landscape as a source of speciation as well as its notable contribution to the herpetological diversity of Cambodia. As such, it should be given special consideration as a conservation priority.

Abstract

The near-complete and articulated skeleton of a new iguanodontian dinosaur, Haolong dongi gen. et sp. nov., from the Lower Cretaceous of northeastern China, preserves exquisitely fossilized skin. The integument includes large overlapping scutate scales along the tail and tuberculate scales around the neck and thorax markedly different from the scale pattern described in other iguanodontians. Remarkably, these scales are interspersed with cutaneous spikes preserved at the cellular level. Tomographic and histological analyses reveal a hollow, cylindrical structure composed of a cornified stratum corneum overlying a pluristratified epidermis with keratinocytes preserved to the level of nuclei, surrounding a porous central dermal pulp. These spikes differ structurally from known protofeathers in non-avian dinosaurs and scaly spines in extant squamates, suggesting a distinct evolutionary origin. Their morphology and distribution imply a primary role in predator deterrence, with potential secondary functions in thermoregulation or mechanoreception. This discovery provides unprecedented insight into the microanatomy of non-avian dinosaur skin and highlights the complexity of skin evolution in ornithischian dinosaurs.

Abstract

The present account describes a new species of alpheid shrimp, Alpheus madhusoodanai sp. nov., belonging to the brevirostris group, collected from the Cochin estuary, the south west coast of India. This represents the first species of alpheid shrimps described from the estuary. The morphological and molecular characteristics of the new species are compared with those of its closely related congeners. The newly described species is separated from its morphological congener A. rapax, by its wider major chela and longer merus of the first cheliped. Molecular data also confirmed the delimitation of A. rapax with A. madhusoodanai sp. nov. Habitat and distribution details are also discussed, highlighting the potential for further taxonomic exploration in the Cochin estuary and the importance in uncovering its hidden biodiversity.

Abstract

Medinilla calanasan is here described as a new species from Calanasan in Apayao Province in northern Luzon (Philippines). It is morphologically distinct from all other known Medinilla species in having horn-like protrusions at the base of the leaf lamina. Morphological similarities with M. clementis Merr. and M. dolichophylla Merr. suggest that M. calanasan may be a member of the M. magnifica-alliance.
