Abstract

Background and aims – Psittacanthus is the largest genus of neotropical mistletoes within Loranthaceae, comprising approximately 110 species. With 37 species recorded to date, Colombia stands as the most diverse country for this group of aerial hemiparasites. Despite this richness, a comprehensive national or regional taxonomic revision of these mistletoes is currently lacking. This study aims to update the knowledge of Colombian Psittacanthus diversity by describing a new species and reporting new records for the country.

Material and methods – This study is based on an extensive literature review and the examination of herbarium material of Psittacanthus. We examined herbarium specimens using both physical collections and high-resolution digital images. Morphological analyses were conducted using dried and rehydrated samples, following the standardized specialized terminology for neotropical mistletoes. Taxonomic descriptions and diagnoses were developed to establish and test taxonomic hypotheses, ensuring a rigorous comparison between focal taxa and previously described species.

Key results – A new species for the Colombian Andes is described, and four new records for the Amazonian and Andean–Amazonian Piedmont of Colombia are reported. Psittacanthus job-kuijtii sp. nov. is described and illustrated herein; this species inhabits the moist lowland forests of the Colombian inter-Andean valleys, which are areas containing exceptional biodiversity. Furthermore, P. amazonicus, P. lamprophyllus, P. pilanthus, and P. zonatus are recorded for the first time for Colombia. The description of this new species and the additional records increase the known diversity of Colombian Psittacanthus to 41 taxa and a total of 111 species for the genus.

Diagnosis. Psittacanthus job-kuijtii differs from the remaining species in the genus by the combination of the following characters: percurrent shoots; leaf blades ovate to broadly lanceolate, base truncate to rounded, margins revolute and adaxially extending toward the petiole, forming a V-shaped projection, apex attenuate to acuminate; inflorescences usually double triads, rarely triple triads, or a monad with two triads (all variations were observed in the holotype); flowers 4–5 cm long in pre-anthesis; petals red to orange in the proximal and medial portions and yellow distally with a deltoid, fleshy basal ligule bearing minute papillae, 1.8–2 mm long; stamens dimorphic, staminal hairs absent. Psittacanthus job-kuijtii is similar to P. peronopetalus, but differs from it by having usually double (rarely triple) triads (vs umbels of four triads), and flowers opening at anthesis with petals recurved for about 2 cm (vs flowers opening only at the apex, with petals recurved for no more than 2 mm).

Abstract

Brachyglaniini is a recently described tribe of Heptapterinae, composed of four genera: Brachyglanis, Gladioglanis, Leptorhamdia, and Myoglanis. Expeditions to the Aripuanã and Tapajós River basins revealed an undescribed species of Brachyglaniini, characterized by a conspicuous light-colored band posterior to the head. Our phylogenetic results provide strong evidence that this new Brachyglaniini species belongs to the genus Leptorhamdia and is closely related to L. marmorata and L. aspredinoides. In addition to the color pattern, the new species can be distinguished from its congeners by having 19-22 anal-fin rays and 47 vertebrae.

Leptorhamdia kamilai, new species

 Diagnosis. Leptorhamdia kamilai can be readily distinguished among its congeners by having a conspicuous light collar-band, yellowish in live specimens, posterior to the head (vs. coloration uniformly throughout body and head, lacking any distinctive bar). Additionally, L. kamilai differs from its congeners by having 19-22 anal-fin rays (vs. 17 in L. essequibensis; 15 in L. marmorata; 32-35 in L. aspredinoides; 12 in L. nocturna, 15-16 in L. schultzi) and by having 46-47 vertebrae (vs. 45 in L. essequibensis; 43 in L.marmorata; 38 in L. nocturna; 56-57 vertebrae in L. aspredinoides and 43 vertebrae in L. schultzi).

Etymology. The specific name, kamilai, honors our dear friend Dr. Kamila Mayumi Duarte Kuabara, an entomologist and lab manager of the Ornithology Department at The Academy of Natural Sciences of Drexel University. A noun in a genitive case.

Abstract

Based on the molecular phylogenetic analyses of six plastid DNA regions (matK and rbcL exons; trnL intron; atpB-rbcL, psbA-trnH and trnL-trnF intergenic spacers) and including 57 samples of Pseuduvaria, as well as thorough morphological studies, Pseuduvaria sirindhorniana (Annonaceae, Miliuseae) is described and illustrated here as a new species from Narathiwat, southern Thailand. The new species belongs to a major clade that also includes P. fragrans, P. gardneri, P. glossopetala, P. kwangtungensis, P. multiovulata and P. phuyensis. Pseuduvaria sirindhorniana is morphologically most similar to P. glossopetala, but differs by having basally connate (vs. free) sepals, larger petals, elliptic-ovate (vs. obovate) outer petals, inner petals that are only connivent at the apex (vs. connivent from the base to ± the midpoint and at the apex), with openings formed from the base (vs. openings formed from ± the midpoint). Pseuduvaria kwangtungensis turns out to be a putative sister of the new species, but the two are morphologically dissimilar in several traits, such as leaf base, inner petal appearance and glands on the inner side of the inner petals.

 DOI: doi.org/10.11646/zootaxa.5821.2.8

 

Abstract

A new species of the genus Stygioides Bruand, 1853 (Lepidoptera: Cossidae) is described from central Turkey. Stygioides hecate Japaridze & Junnilainen sp. nov. is based on material collected in the Sultan Daðlarý Mountains (Konya Province). The new species is characterised by its distinct wing coloration in females. Adults are diurnal, as in other members of the genus, and were collected by daytime netting. DNA barcode data (COI) are provided and compared with available sequences in the Barcode of Life Data Systems (BOLD Systems), supporting the distinctiveness of the new taxon. The discovery of this species increases the number of Stygioides species to 10 and those from Turkey to three, thus contributing to a better understanding of the diversity and distribution of the genus in the Palaearctic realm.

Stygioides hecate Japaridze & Junnilainen sp. nov. 

Diagnosis: Males of S. hecate Japaridze & Junnilainen sp. nov. differ from S. nupponenorum by the presence of a distinct white tip of the male abdomen and white scales on the antennae, the absence of brown piliform scales on the abdomen, a narrower apex of the valvae, and a shorter saccus (Figs 1A–1B, 2 C; cf. Lingenhöle et al. 2016: fig. 6; Yakovlev 2011: fig. 35). Females are readily distinguished from all congeners by the presence of golden-yellow scales on the antennae, head, thorax and wings (Figs 1C–1D; cf. Lingenhöle et al. 2017: figs 1–3, 9; Japaridze et al. 2025b: fig. 22).

Etymology: The species name is derived from Hecate, the ancient Greek goddess associated with the night and commonly depicted carrying yellow or golden torches. This name alludes to the coloration of the holotype female, which is predominantly black with yellow-golden scales on the wings, thorax, head, and antennae.

[Herpetology • 2026] Pristimantis fergusoni • A New spiny frog of the Genus Pristimantis (Anura: Strabomantidae) from the eastern slopes of the Ecuadorian Andes

 

Pristimantis fergusoni

DOI: doi.org/10.3897/zookeys.1269.162260

Abstract

A new species of rain frog from the upper montane forest of the eastern Andes in the upper Pastaza watershed, Ecuador is described. Pristimantis fergusoni sp. nov. is characterized by its short snout, conical tubercles on upper eyelids and heels, combined with a scarlet colored belly in females. These unique traits differentiate the new species among other Pristimantis of upper montane eastern Ecuadorian Andes. Phylogenetic analyses support its validity and place it within a clade nested with other tuberculated species occurring along the Andean slopes. Pristimantis fergusoni sp. nov. is currently known from only two close localities (Cerro Candelaria and Chamana Reserves) at elevations between 2972 and 3200 m elevation, within the Llanganates-Sangay Ecological Corridor. Data Deficient IUCN status is proposed until new information is available. Individuals were observed at night perched on vegetation in herbaceous and arbustive vegetation of upper montane forest. This discovery contributes to a growing body of evidence identifying the upper Pastaza valley as a hotspot of amphibian endemism and diversification. With this addition, 30 strabomantid species are described for this region in the last decades, underscoring its conservation importance. This discovery highlights the urgent need for integrated taxonomic efforts combining fieldwork, morphology, and molecular data to resolve complex evolutionary relationships within the megadiverse genus Pristimantis, especially in underexplored high-elevation habitats of the tropical Andes. Finally, we provide an updated phylogeny for this clade that clarifies its evolutionary relationships.

Abstract

Southwest China is extremely rich in fungal resources, and a large number of new taxa have been discovered in recent years. In the present study, we examined 26 specimens of the genera Hydnum and Lentaria sensu lato, most of which were obtained in Yunnan Province. Through ITS-nrLSU-tef1 phylogenetic analysis, combined with morphological studies and geographic analyses, five new species were described, viz. Hydnum cremeum, H. flavoquamosum, H. roseoalbum, H. roseotangerinum, and L. subalpina. Furthermore, we also supplied new information on some known species, including host plants and new distribution records. We re-examined the holotype sequences of two known taxa, H. flabellatum and H. pallidomarginatum, treating H. flabellatum as a synonym of H. pallidomarginatum. Additionally, a key to Lentaria s.l. in China was provided.

Diaphanes meghalayanus sp. nov., is characterised by a unique colour pattern of the central disc, the absence of a typical circular pronotal areolet area, brownish-yellow pronotum and elytra, and other specific features of male genitalia. Diaphanes mawlynnong sp. nov., is distinct with rare moniliform antennae, circular-shaped pronotal areolet areas with blunt posterior lateral corners, and specific genital aedeagus characters. The female of D. mawlynnong sp. nov., which is apterous, was found in the same habitat where its males were associated. 13 Diaphanes species have been recorded from India, and with the discovery of these two new species, the number of Diaphanes species recorded in the country increases to 15. This knowledge significantly contributes to the existing information gap of Diaphanes diversity and distribution in this region.

Abstract

A new species, Sclerocardius lyali sp. nov., is described and illustrated from Mae Hong Son Province, Thailand. The new species is close to Sclerocardius indicus Hartmann, 1903, but differs in the body covered with short setiform yellowish and pale scales, the postero-ventral side of the protibia lacking teeth, a pronotum with quite large punctation, and a narrower aedeagus. This is the first record of Sclerocardius Schoenherr, 1847, from Thailand. A key to Asian species of the genus Sclerocardius is also given.

Etymology. Patronymic. In honour of Christopher H.C. Lyal (London, UK), who revised the genus

Sclerocardius.

Diagnosis. This new species is closely related to Sclerocardius indicus Hartmann, 1903, but differs in that it has short setiform yellowish and pale scales on the body, a postero-ventral side of the protibia without teeth, a pronotum with quite large punctation, and a narrower aedeagus. Sclerocardius indicus is characterised by a body covered in long, narrow, orange scales; a pronotum with relatively small punctation; a postero-ventral side of the protibia with three rounded teeth; and the aedeagus is also wider.

[Herpetology • 2026] Adenomera varcena • A New Species of Terrestrial Foam-Nesting Frog (Anura: Leptodactylidae) from the Várzea Forests of Western Amazonia

Abstract

Cryptic diversity within species poses a challenge to traditional taxonomy, often leading to underestimation of species richness and incorrect assessments of extinction risks. The taxonomy of Adenomera frogs has greatly benefited from the integrated assessment of morphological, acoustic, and DNA sequence data. Here we address a taxonomic problem by analyzing the external morphology, color patterns, advertisement calls, and genetic variation of one of the nine molecular lineages of the Adenomera simonstuarti species complex, distributed in western Amazonia. Based on novel data from the upper Juruá River, in northwestern Brazil and Ecuador, we found that this lineage exhibits significant differences in morphology (body size), coloration (absence of a solid stripe on the ventral surface of the forearm), and calls (nonpulsed and formed by a single type of note) in comparison with congeners. This combination of phenotypic traits supports the taxonomic distinction of this lineage, which is formally described as a new species. Interestingly, the new species uses várzea (seasonally flooded) forests as its calling and breeding habitat, a unique feature among forest-dwelling Amazonian species of the genus, which are always associated with terra firme (non-flooded) forests. This study reinforces the relevance of acoustic mating signals combined with DNA sequences in uncovering new species, contributing to a better understanding of the anuran diversity in Amazonia.

La diversidad críptica dentro de las especies plantea un desafío a la taxonomía tradicional, lo que ocasiona una subestimación de la riqueza de especies y evaluaciones incorrectas del riesgo de extinción. La taxonomía de las ranas del género Adenomera ha experimentado un avance notable mediante la evaluación integrada de datos morfológicos, acústicos y de secuencias de ADN. En este estudio, abordamos un problema taxonómico mediante el análisis de la morfología externa, los patrones de color, los cantos de anuncio y la variación genética de uno de los nueve linajes moleculares del complejo de especies de Adenomera simonstuarti, distribuido en la Amazonia occidental. Con base en nuevos datos del alto río Juruá, en el noroeste de Brasil, y Ecuador, encontramos que este linaje presenta diferencias significativas en morfología (tamaño corporal), coloración (ausencia de una banda sólida en la superficie ventral del antebrazo) y cantos (no pulsados y formados por un solo tipo de nota) en comparación con sus congéneres. Esta combinación de caracteres fenotípicos apoya la distinción taxonómica de este linaje, que se describe formalmente como nueva especie. Curiosamente, la nueva especie utiliza bosques de várzea (inundados estacionalmente) como su hábitat de vocalización y reproducción, una característica única entre las especies amazónicas del género que utilizan hábitas boscosos, específicamente asociadas a bosques de tierra firme (no inundados). Este estudio refuerza la relevancia de las señales acústicas reproductivas combinadas con secuencias de ADN para descubrir especies nuevas, contribuyendo a una mejor comprensión de la diversidad de anuros en la Amazonia.

Abstract

Species of Gymnopus sect. Levipedes are challenging to delimitate due to the morphological similarity among different taxa. In this study, morphological characteristics, molecular phylogenetic data, and ecological traits were integrated to investigate the species diversity of this section of southwestern China. A total of 17 species were documented in the region, including three new species, namely G. sinobrevipes, G. flavoalbus, G. yunnanensis, and two species new to the studied area—G. bicolor and G. ocior. Detailed descriptions and illustrations of the three new species are presented, along with comparisons to closely related or morphologically similar species. The remaining species included five that were originally described from southwestern China, four that were first identified from Europe, two from the Republic of Korea, and one from North America. Six of these species, originally described outside of China, currently lack molecular evidence to support their distributions in southwestern China. Finally, 11 species with morphological and molecular evidence were recognized in southwestern China. A key to these species is also provided.
