Abstract

Two species of Stigmatodactylus have recently been observed in the Arfak Mountains of West Papua Province, Indonesian New Guinea. One of these is clearly undescribed and is here described as Stigmatodactylus antennatus Schuit., Saputra & Wanma, a species uniquely characterised by the presence of a pair of antennae on the lip. The other is believed to be S. gibbsiae (Kores) Kores. This species was only known from the type material collected in the Arfak Mountains more than a century ago, in 1913. There are, however, significant discrepancies between the protologue and the material recently found. We interpret these discrepancies as misinterpretations of the poor type material of S. gibbsiae, and provide images based on fresh material. An identification key to the four species of Stigmatodactylus in New Guinea is included.

DOI: doi.org/10.21829/abm132.2025.2421 

Abstract

Background and Aims: Axinaea is a predominantly Andean genus, with one species found in the mountains of Costa Rica and Panama. It is similar to Meriania, and the only feature that separates them from each other is the shape of the dorsal connective of the anther. The discovery of a new species, described here, with anther connective characters intermediate between the two genera, raised the need to improve the circumscription of Axinaea and document variation within Meriania, aspects that are addressed in this paper.

Methods: A new species of Axinaea is described from collections deposited in the UDBC herbarium of the Distrital University of Bogotá. The degree of threat is evaluated and the need for conserving the species is described. In addition, various groups within Meriania, including Axinaea, are summarized, and a unique set of characters for Axinaea is proposed.

Key results: Axinaea filandiensis sp. nov. is characterized by its 4-merous flowers, isomorphous stamens with blue anthers and globose-ellipsoid dorsal connectives. It is known only from the type locality and its conservation status is proposed as Critically Endangered (CR). Seven groups are described in Meriania, including Axinaea, and a unique set of characters is proposed for the latter genus, considering non-nectariferous flowers, cucullate corolla, isomorphic or slightly dimorphic stamens, anthers with the vascular bundle of the connective tissue directed backwards, and inappendiculate and globose to globose-elliptic connective. According to this circumscription, one species described in Meriania (M. rubrifolia) establishes its position within Axinaea.

Conclusions: Axinaea filandiensis represents a critically endangered species that requires urgent conservation action. The unique set of characters established in this paper clarifies the separation between Axinaea and Meriania. It is proposed to maintain both genera separate, considering that Meriania is an artificial group that should be split into several genera.

Abstract

Subterranean animals are commonly met with considerable fascination, by both laymen and biologists. While most of these animals have been reported from caves, some species have adapted to other underground habitats. One special subterranean aquatic habitat are aquifers, which are home to a number of invertebrates and fishes. Of the more than 300 known subterranean fishes, fewer than 10% have been recovered from aquifers and are encountered only rarely and serendipitously. Here we report the discovery of a tiny, blind loach of the family Cobitidae from a dug-out well in Assam, India, which exhibits a number of characters commonly associated with subterranean life, so-called troglomorphies. This loach, described here as Gitchak nakana, represents a new genus and species, differing from all other genera of cobitids by a number of unique characters. The most unusual among these is the complete lack of a skull roof with the brain covered dorsally only by skin. Gitchak nakana is the first aquifer-dwelling (phreatobitic) fish from Northeast India, and marks the first discovery of a previously unknown subterranean fauna in this part of Asia.

Taxonomy 

Gitchak, new genus 

Diagnosis. Gitchak is a member of the family Cobitidae as evidenced by (i) the modification of lateral ethmoid into a bifurcated subocular spine, which articulates with the orbitosphenoid, (ii) the reduction of the endopterygoid into a rod-like element, (iii) the absence of contact between orbitosphenoid and pterosphenoid and (iv) the outer arm of the os suspensorium completely surrounding anterior swimbladder chamber.

Etymology. The genus name is derived from the Garo word gitchak, meaning red, alluding to the striking red life colour of this loach. Treated here as a noun in the feminine gender.

Gitchak nakana, new species.

 

Etymology. The specific name is derived from the Garo words na·tok, fish, and kana, blind, referring to the absence of eyes in this species, a noun in apposition.

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.

Kliukin, Poyarkov, Bragin, Krone & Nguyen

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.

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

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.
