Abstract

An integrative approach based on morphological characteristics and DNA data from the mitochondrial COI gene has revealed five new species of the pill millipede genus Rhopalomeris Verhoeff, 1906 from Thailand: Rhopalomeris muka Sapparojpattana & Likhitrakarn, sp. nov., R. lentiginosa Sapparojpattana & Likhitrakarn, sp. nov., R. dulcia Sapparojpattana & Likhitrakarn, sp. nov., R. punctata Sapparojpattana & Likhitrakarn, sp. nov., and R. verhoeffi Sapparojpattana & Likhitrakarn, sp. nov. The five new species are distinguishable from their congeners by distinctive color patterns and telopod structure. The interspecific genetic divergences between the new species and other Rhopalomeris species ranged from 7.86 to 13.71%. Intraspecific genetic divergences within these five species ranged from 0 to 4.53%, with the highest divergences found in R. carnifex and R. verhoeffi sp. nov. This is consistent with both the wide distribution range and the significant intraspecific morphological variations observed in these latter two species. Furthermore, the taxonomic scope of R. carnifex in Thailand is reviewed, and intraspecific morphological variations within R. carnifex and R. verhoeffi sp. nov. are discussed. A distribution map, morphological illustrations from SEM, and an updated key to all known Rhopalomeris species are also provided.

ABSTRACT

The early-middle Miocene deposits of St Bathans, New Zealand, are renowned for their diverse and internationally important avian fossil biota that includes an abundance of fragmentary yet recognisable fossils from the crown bird clade Anseriformes (ducks and geese). We reviewed the taxonomic status of 11 isolated fossil bones previously referred to geese (Anserinae, Anseriformes) from St Bathans. Rigorous reassessment of these specimens using an expanded comparative morphological dataset demonstrated that four specimens can be assigned to the tadornine Miotadorna sanctibathansi and five are probably from a large anatid, potentially the purported anserine Notochen bannockburnensis. A second, slightly smaller, probable anserine is represented by one or possibly two bones, which we name as a new species, Meterchen luti gen. et sp. nov. We did not find any bones that showed a clear affinity with cereopsine anserines, thereby contradicting a previous hypothesis that cereopsines have a long history in Zealandia dating back to at least the early-middle Miocene. Our findings are consistent with current molecular divergence time estimates suggesting that the ancestors of the recently extinct cereopsine Cnemiornis arrived in Zealandia in the late Miocene.

[Crustacea • 2025] Trichocallia delicatula • A New Genus and Species of the Ghost-shrimp Family Callianideidae (Decapoda: Axiidea) from the Caribbean coast of Panama

Trichocallia delicatula   

Anker, 2025 

 

DOI: doi.org/10.11606/1807-0205/2025.65.009

Abstract   

A peculiar new species of ghost-shrimp from Bocas del Toro Archipelago on the Caribbean coast of Panama is assigned to the genus Trichocallia gen. nov. in the family Callianideidae. The holotype and presently the only known specimen of Trichocallia delicatula sp. nov. was collected with a suction pump on a silty-muddy bottom under a network of decomposing and partly overgrown mangrove roots. The new genus appears to be most closely related to Callianidea H. Milne Edwards, 1837, with two species in the Indo-West Pacific, and Paracallianidea Sakai, 1992, with two species, one in the western Atlantic and one in the eastern Pacific.

DOI: doi.org/10.3897/phytokeys.271.172410

Abstract

Homalomena lingua-felis is newly described from Tapanuli (North Sumatra Province, Indonesia). This species resembles H. pexa from which can be easily distinguished by its shorter petiole (2.0–4.5 cm vs. 7.0–12 cm), papillate petiole (vs. densely white-tomentose), elliptic or cordate to ovate leaf shape (vs. oblong- to ovate-cordiform), papillate abaxial leaf surface (vs. sparsely hairy), papillate veins (vs. tomentose), papillate peduncle and spathe (vs. tomentose), pendulous peduncle (vs. semi-erect to declinate), and conical staminate flower zone (vs. ellipsoid). This novelty represents a continuation of discoveries on hairy Homalomena in Sumatra.

Homalomena lingua-felis A.S.D.Irsyam, Raynalta & M.R.Hariri, sp. nov.

 

Diagnosis. Homalomena lingua-felis is similar to H. pexa but differs by having shorter petiole (2.0–4.5 cm vs. 7.0–12 cm), papillate petiole (vs. densely white-tomentose), elliptic or cordate to ovate leaf shape (vs. oblong- to ovate-cordiform), papillate abaxial leaf surface (vs. sparsely hairy), papillate veins (vs. tomentose), papillate peduncle and spathe (vs. tomentose), pendulous peduncle (vs. semi-erect to declinate), and conical staminate flower zone (vs. ellipsoid).

Etymology. The specific epithet lingua-felis is derived from the Latin lingua (tongue) and feles (cat), in reference to the characteristic texture of the leaf surface, which bears a resemblance to the rough surface of a feline tongue.

Abstract

The subfamily Monotropoideae (Ericaceae) comprises unique non-photosynthetic and mycoheterotrophic plants. Their extensive morphological reduction often poses significant challenges for species delimitation. In this study, we investigated an unknown Monotropa taxon collected from Hunan Province, China, through an integrative approach combining detailed morphological observation and phylogenetic analysis. We sequenced it, assembled the complete plastid genome and reconstructed phylogenetic trees using both chloroplast genomes and the nrITS region. Morphologically, this new entity is readily distinguished from its congener, Monotropa uniflora, by several key characteristics: 4–5 glabrous petals apically one-quarter orange and basally three-quarters white, 8–10 stamens with glabrous filaments, a nodding berry at maturity and a distinctly earlier flowering period (March–June vs. June–October). Phylogenetic reconstructions, based on both chloroplast genomes and nrITS data, consistently resolved this unknown taxon as a distinct lineage, clearly separating it from M. uniflora with strong support. Integrating evidence from morphology, phylogeny and phenology, we hereby describe it as a new species, Monotropa callistoma.

Monotropa callistoma Ze Wei, Li J.Liu & Bing Liu, sp. nov.

 

Diagnosis. Monotropa callistoma is characterised by its 4 or 5 glabrous petals (apically orange and basally white), 8–10 stamens with glabrous filaments, flowering period starting from March and nodding capsule at maturity. It is morphologically most similar to M. uniflora and Monotropastrum humile, but differs by the characters summarised in Table 2.

Etymology. The specific epithet callistoma is derived from the Greek calli- (beautiful) and -stoma (mouth), alluding to the aesthetically pleasing form and colouration of the corolla orifice.

[Botany • 2025] Axinaea filandiensis (Melastomataceae: Merianieae) • A New Species from Colombia, and Comments on the Circumscription of Axinaea and groups in Meriania

 Axinaea filandiensis Humberto Mend. & W. Vargas,  

  

 in Mendoza Cifuentes et Vargas, 2025.

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

The taxonomy of Achalinus jinggangensis has long remained unclear due to limited sampling and the consequent lack of publicly available molecular and distributional data. Here, we re-evaluate the taxonomic status of A. jinggangensis using an integrative approach that combines molecular phylogenetic analyses, detailed morphological comparisons, and direct examination of type material, and provide a comprehensive redescription of this species. In addition, we describe an unexpected new species from Kuocang Mountain, Linhai City, Zhejiang Province, China, Achalinus mirabilis sp. nov. Phylogenetic analyses indicate that Achalinus mirabilis sp. nov. appears to be most closely related to A. jinggangensis, although this relationship is not statistically supported, and exhibits substantial genetic divergence, as indicated by uncorrected p-distances of 9.5%–10.9% in the CO1 gene fragment. Morphologically, the new species is readily distinguished from A. jinggangensis by its distinctly keeled outermost dorsal scale row, a higher number of ventral scales in both sexes, and conspicuous differences in coloration. Our results highlight previously underestimated species diversity within Achalinus and refine the current understanding of its taxonomy. This study increases the number of recognized species in the genus Achalinus to 30, and underscores the importance of integrative approaches in resolving cryptic diversity and taxonomic complexity within the genus.

Achalinus mirabilis Xu, Hu, Qi, Zhang, Zhou, Xu, Wang & Peng, sp. nov.

Diagnosis. The new species Achalinus mirabilis sp. nov. is distinguished from all of its congeners by a combination of the following morphological characters: (1) size medium, with a maximum SVL of 270 mm in males and 332 mm in females; (2) tail relatively short, TAL/TL ratio 0.22 in males and 0.17–0.18 in females; (3) loreal scale absent; (4) length of suture between internasals substantially longer than that between prefrontals, LSBI/LSBP ratio 1.60–3.35; (5) dorsal scales strongly keeled, arranged in 23 rows throughout the body, with the outermost row also strongly keeled and substantially enlarged; (6) infralabials 6, with the anterior three or four in contact with the first pair of chin shields; (7) two pairs of chin shields; (8) maxillary teeth 27 based on the only counted female specimen; (8) ventral scales 163–166 in males and 174–178 in females; (9) subcaudals 64–68 in males and 53–56 in females, not paired; (10) in life, the dorsum is brown to dark brown with a slight metallic sheen, and the venter is uniformly light brown.

Etymology. The specific epithet mirabilis represents a Latin adjective in nominative singular, meaning “marvelous” or “remarkable”, and is given in reference to the distinctive morphology of this species within the genus Achalinus. In addition, the discovery of a previously unrecorded new species in Taizhou City, Zhejiang Province, a highly urbanized and economically developed region, was also unexpected. Based on its known distribution, Kuocang Mountain (Kuocangshan) in Linhai City, Taizhou City, Zhejiang Province, China, we propose the Chinese common name “括苍山脊蛇” (Kuò Cāng Shān Jǐ Shé) and the English common name “Kuocang Moutain odd-scaled snake”.

Abstract

Bucerocaputis Souza-Gonçalves & Lopes-Andrade, gen. nov., a new genus with two species, Bucerocaputis kapinawa Souza-Gonçalves & Lopes-Andrade, gen. et sp. nov. from the Caatinga biome and Bucerocaputis timbira Souza-Gonçalves & Lopes-Andrade, gen. et sp. nov. from the Cerrado biome, is described based on individuals collected in the states of Bahia, Maranhão, Pernambuco and Rio Grande do Norte, Northeast Region of Brazil. The genus shares some morphological affinities with members of Acanthocis Miyatake, 1954, Falsocis Pic, 1916, Plesiocis Casey, 1898, Porculus Lawrence, 1987 and Pseudeuxestocis Lawrence 2016; however, it can be distinguished mainly by the combination of the following features: the robust body; single pronotal and elytral punctation; antennae with 10 antennomeres; apical maxillary palpomere inflated with a large circular sensory area at the apex; prosternum biconcave with a relatively broad, strongly curved prosternal process, projecting below the plane of the prosternum disc; and male anterocephalic and anterior pronotal edge quadridentate. We also provide information on its host fungi and briefly discuss its geographical distribution.

Abstract

A new genus and species in the Mucoromycota, Mooraboolomyces wintlei, was isolated into culture from leaf litter from a national park in Victoria, Australia, and is described. The strain reproduced asexually to form sporangia and sporangiospores, with no production of zygospores, and sequencing of its genome and analysis supported a heterothallic mode of reproduction. Phylogenetic analyses using five DNA regions placed the strain within the Mucorales and Mucoraceae, clearly distinct from previously described genera. This represents the second genus in this phylum that has been identified from Australia and that is currently unique to this country.

Abstract

A species could not be known to the world of science if it not be discovered and described, considerable number of new species are neglected due to the plant itself and some other external restricted factors. On the basis of morphological and molecular evidences, a new species previously identified as Salvia scapiformis is now described and illustrated as Salvia tainingensis, named after Taining County in Fujian Province, where it was discovered. S. tainingensis does not closely resemble S. scapiformis, but is more similar to Salvia glabrifolia and Salvia daiguii, which were once identified as S. scapiformis, in terms of leaf shape, apex, base, corolla color, and connective length. However, it can be easily distinguished from the latter two by its thinly leathery leaves, serrate leaf margins, densely villous or glabrescent leaf abaxial, and the X-shaped arrangement of connective and filament.

[Botany • 2026] Stigmatodactylus antennatus (Orchidaceae) • A New Species from West Papua Province, Indonesia, and the Rediscovery and Reinterpretation of S. gibbsiae

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.

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.

Gitchak nakana. (a) ZSI FF11123, holotype, 20.8 mm SL, in life, sides reversed, showing overall appearance, note presence of large eggs in body cavity and numerous fat globules (reflective spheres) along dorsal midline and postanal ventral midline. (b) same specimen, after preservation. (c) same specimen, µCT-image to illustrate presence of eight large eggs arranged in a longitudinal series. (d) same specimen, in life, actively swimming in the water column; note large yellow eggs and blood red liver. (e) KUFOS2025.F.11.51, non-type, 16.4 mm SL, in life, close-up of lateral head and body; note swimbladder visible through body wall. (f) KUFOS:2025.FT.11.6, paratype, 20.0 mm SL, frontal view of head to illustrate crown of barbels; note large-calibre red blood vessels supplying rostral (rb), maxillary (mxb) and mandibular (mdb) barbels and small-calibre vessels supplying nasal (nb) and tiny mental barbels (marked by arrow).

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.
