Abstract 

The thin-toed geckos of the Cyrtopodion agamuroides-gastropholis species complex represent a taxonomically challenging group of geckos whose systematic and phylogenetic relationships remain poorly resolved. A dataset comprising 251 specimens belonging to the agamuroides-gastropholis complex was analyzed, based on material collected over a period of 20 years. A morphological comparison of external features revealed a high degree of species diversity within this group. We present the first preliminary data from analysis of the mitochondrial DNA barcoding (COI). The species delimitation analysis is consistent with the morphologically based species diversification, allowing an estimation of the species diversity within this group. The results of this study have led to the description of ten new species of the agamuroides-gastropholis complex, conditionally placed in the genus Cyrtopodion. The present study also discusses the biogeography, evolution, and speciation of this group. Further revision of the genus taxonomy of these geckos is needed, as well as a more detailed genetic and genomic study.

ABSTRACT

A new species of Mitrephora is described from Arunachal Pradesh, India. It can be distinguished from its congeners based on a combination of morphological characters such as evergreen leaf phenology, unbranched inflorescences with up to 8 flowers, inner petals being subequal or equal in length relative to the outer petals and stipitate, beaked, cylindric monocarps. This species is unique in the shape and geometry of the miter (dome) which is longer than broad (length: diameter ratio 1.25). This species is also the only andromonoecious species known in the genus to date. This discovery represents only the second record of the genus from the Himalayan Biodiversity Hotspot.

  DOI: doi.org/10.24823/ejb.2026.3605

Abstract

Adenosciadium omanensis, a species new to science, is described from the foothills of the northern mountains of Oman. It is closely related to Adenosciadium arabicum but differs in having a reniform leaflet with finely serrate margin, a compact inflorescence, lanceolate bracts and bracteoles with acute tip, a cylindrical fruit (schizocarp) with narrow commissure, oblong-oval terete mericarps with an exocarp covered with long forked hairs, and an emarginate endocarp on the commissural side. Adenosciadium omanensis is illustrated by photographs in its natural habitat. In addition, a comparative morphological analysis is presented that distinguishes it from Adenosciadium arabicum, the single species known in the genus, from southern Oman and Yemen. A distribution map for the two species in Oman is provided.

Abstract

We describe a new species of widow spider (Araneae, Theridiidae, Latrodectus) from the Andean region. DNA barcode sequences are provided. The species is documented from museum specimens across Peru and identified from photographs on iNaturalist, extending its inferred distribution into Ecuador, Bolivia, and Chile. We integrate specimen and citizen-science occurrences to generate a species distribution model using WorldClim bioclimatic variables, predicting highest suitability along temperate to high-elevation Andean regions. We discuss the utility and limitations of citizen-science imagery for delimiting and mapping species and summarize available information on clinical aspects of envenomation in Peru associated with the local “lucacha” widow spider.

Abstract

The collar-door wishbone spiders of the genus Kwonkan Main, 1983 are an Australian-endemic lineage of mygalomorph spiders that often construct elaborate burrow entrances, including collars and turrets, and remain poorly documented across their range, despite museum collections indicating high local endemism and substantial undescribed diversity. Much of the existing taxonomy, including nine of the 14 currently described species, was based on limited material and lacked modern morphological or molecular approaches to species delimitation, hindering efforts to document the remaining diversity and address conservation concerns. Here, we redescribe all nine legacy species and review Kwonkan diversity within the south-western Western Australian (SWWA) agricultural region, a highly fragmented and mostly cleared landscape harbouring extensive undescribed diversity and the threatened species K. eboracum Main, 1983. In the process, we clarify species identities, present the first molecular data for several species including K. eboracum, and describe two new species (K. elatus sp. nov. and K. yorkrakine sp. nov.) that were previously attributed to legacy species. In our review of the SWWA agricultural region fauna we identify 29 putative undescribed species and a pattern of extensive sympatry, fine-scale species turnover, and extremely restricted ranges. These findings highlight the need for continued revisionary work and potential conservation listing of additional described species such as K. wonganensis (Main, 1977).

Abstract

New Caledonia is a biodiversity hotspot with high levels of micro-endemism, yet its gracillariid fauna remains poorly documented. Here, two new species of Caloptilia Hübner, 1825 (Gracillariidae) are described from Glochidion J.R.Forst. & G.Forst. (Phyllanthaceae) host plants in Parc des Grandes Fougères, New Caledonia: Caloptilia augeas Guiguet, Lopez-Vaamonde, van Nieukerken & Ohshima, sp. nov., and Caloptilia ceryneia Guiguet, Lopez-Vaamonde, van Nieukerken & Ohshima, sp. nov. Both species induce leaf galls on Glochidion billardierei Baill., co-occurring on the same host species, sometimes even on the same leaf. They exhibit distinct wing patterns, but very similar male and female genitalia, and DNA barcoding supports their status as separate species. These findings provide evidence for potential within-host sympatric speciation, as documented in other gall-inducing insects. The larval biology of C. augeas and C. ceryneia reveals a unique frass disposal behaviour, whereby waste is excreted through a hole and the aperture is subsequently sealed—an adaptation not previously reported in gall-inducing Lepidoptera. Our findings double the known number of gall-inducing species in Gracillariidae, highlighting that this life history strategy may be more common than currently appreciated. We also provide new information on distribution and host plants of Caloptilia xanthopharella (Meyrick, 1880), a leaf roller found on the same host plant, G. billardierei. These findings mark the first records of the subfamily Gracillariinae in New Caledonia. This study underscores the underexplored diversity of New Caledonian gracillariids and emphasises the conservation value of Parc des Grandes Fougères. Further surveys in the Indo-Pacific region may reveal additional yet undescribed Caloptilia species associated with Phyllanthaceae and help clarify the evolutionary mechanisms underpinning their diversification.

Caloptilia augeas Guiguet, Lopez-Vaamonde, van Nieukerken & Ohshima, sp. nov., 

Etymology. The specific name augeas refers to the fifth Labour of Hercules in the Greek mythology. The larval behaviour of frass cleaning in the gall reminds this Labour that consisted in cleaning the stables of king Augeas (Αὐγέας). This name comes from the word “αὐγή” that designates “sun shine” and “reflection of a shiny object” in Classic Greek (Bailly 1899), referring to the bright colour of the adult wings. The epithet is to be regarded as a noun in apposition.

Caloptilia ceryneia Guiguet, Lopez-Vaamonde, van Nieukerken & Ohshima, sp. nov.

Etymology. The specific name ceryneia refers to the ancient Greek city of Ceryneia or Keryneia (Κερύνεια), the location of the Ceryneian Hind from Greek mythology, which features in the third Labour of Hercules. The moth’s striking yellow and red wing pattern evokes the golden antlers and bronze hooves of the mythical deer. Its cryptic gall-inducing behaviour also recalls the elusive nature of the Ceryneian hind, which was known for its ability to remain hidden. The epithet is to be treated as a noun in apposition.

Abstract

Deep-sea visual environments show extreme gradients in light intensity, driving divergence in eye morphology. In the order Amphipoda, such specializations are documented in pelagic hyperiideans, whereas deep-sea Eusiridae remain poorly known. During a bathypelagic survey in Japan, we collected a eusirid amphipod with conspicuously enlarged eyes. Integrative taxonomy, using morphology and four DNA barcoding regions, shows that it represents a new species of the monotypic genus Harcledo Barnard, 1964, described here as Harcledo toyoshioae sp. nov. It is characterized by markedly enlarged eyes that cover most of the lateral head and meet across the dorsal midline, and by a distinctive maxilla 1 armature. Phylogenetic analyses place H. toyoshioae sp. nov. within Eusiridae but leave its relationships to H. curvidactyla unresolved, owing to the lack of sequence data. Comparisons with historical records suggest rapid diversification of eye size within this clade and indicate that it is unlikely to be governed by depth or pelagic–benthic mode alone. We propose that the enlarged eyes are plausibly associated with a pelagic lifestyle in dim mid-water habitats, while noting that this interpretation remains tentative. Our findings highlight visual specializations in deep-sea eusirids and the value of combining new collections, historical literature, and molecular data when reassessing deep-sea taxa.

Abstract

Corybas apoensis, a new species of tribe Acianthinae endemic to Mindanao, is described herein. Among the currently recognized species of the tribe, it most closely resembles C. viridisepalus in overall floral morphology, particularly in having upright flowers borne on a slender, cylindric, erect ovary and the flower possessing a dorsal sepal and labellum tinged with conspicuous carmine veins. Both species further share a pilose labellum. However, this notable new species is distinct by having white floral background and a dorsal sepal being densely papillate on the abaxial surface. We also provided a summarized key morphological characteristics that distinguishes our new species from the later.

[Herpetology • 2026] Allobates tanaru • The First Chlorotic Species of the Superfamily Dendrobatoidea: A New Nurse Frog of the Allobates albiventris Complex (Anura: Aromobatidae) with remarkably greenish hatchlings from Brazilian Amazonia

 Allobates tanaru 

Dantas, Ferrão, Cunha-Machado & Lima, 2026

 DOI: doi.org/10.3099/0006-9698-579.1.1

 Abstract -

While many frogs around the world have blue-green tissues because of the accumulation of a pigment called biliverdin, this had never been observed in nurse or poison frogs until now. In this study, we describe a new species of nurse frog from southwestern Amazonia that breaks new ground in Neotropical amphibian taxonomy: It is the first chlorotic species—with greenish hatchlings—ever recorded in the large superfamily Dendrobatoidea. Previously lumped within Allobates albiventris, integrative taxonomy reveals it as a distinct species, supported by a set of morphological and bioacoustic traits. It differs from most of its congeners by a call consisting of a pair of notes emitted in a single exhalation; males with lateral expansions on fingers II and III, and a white vocal sac covered with melanophores; dark brown oocytes, hatchlings with greenish yolk, and tadpoles with two or three short, pyramidal papillae distributed in a single row on each lateral margin of the anterior lip. Beyond its diagnostic features, this discovery is notable because chlorotic tissues were previously unknown in Dendrobatoidea, a superfamily with more than 350 species known for its terrestrial habitat, territoriality, carrying behavior, and nonchlorotic adults. The distinctive greenish hue seen in embryos of certain species, particularly in the new Allobates, may serve as an adaptation for predator avoidance, and it also highlights the ecological plasticity and morphological diversity within the genus. This opens fresh avenues to study the ecological, evolutionary, and developmental significance of biliverdin in frogs using a lineage wherein the biology contrasts with classic model species.

Etymology: The specific epithet tanaru is a noun in apposition and honors the indigenous Tanaru, known in Portuguese as Índio Tanaru and Índio do Buraco (Indigenous Tanaru and Indigenous of the Hole, respectively). Tanaru died on 23 August 2022; he was the last representative individual of a poorly known ethnic group that lived in Rondônia, Brazil. His people were exterminated by gunmen at the behest of illegal loggers in 1995. After that, Tanaru lived isolated for almost 30 years in the Tanaru Indigenous Land, located in the southeast Rondônia, approximately 700 km from Rondônia's capital. Because the Tanaru Indigenous Land does not have a consolidated land demarcation and is surrounded by agricultural farms, the land suffers continuous threats and attacks, some of which started just some days after Tanaru's death. The indigenous Txai Suruí, from the Suruí ethnic group, said: “Known for his solitude, Tanaru resisted the contact with non-indigenous people until his last days after so much trauma and violence. His territory must continue to represent resistance and must be preserved and cared for, becoming a permanent conservation area.”

Abstract

A new lace bug, Paleoanomala decapitata sp. nov. (Tingidae, Tingiometrinae), is described from Lower Cretaceous (upper Albian) amber of Peñacerrada I (Burgos, Spain). The genus Paleoanomala was previously known only from Cenomanian Kachin amber of Myanmar, and the discovery of this new species significantly expands its palaeogeographical range as well as the known diversity of lace bugs from Spanish amber deposits. Furthermore, the description of the new species urged us to undertake a reinterpretation of forewing venation in early lace bugs, finding nearly identical venation patterns in the extinct genera Paleoanomala and Tingiometra (Tingiometrinae), and Hispanocader (Hispanocaderidae). Based on this revised interpretation and other shared morphological characters, the extinct tingid subfamily Tingiometrinae and the family Hispanocaderidae are synonymized with Ebboidae, which is here treated as the subfamily Ebboinae stat. nov. within Tingidae. Additionally, Paleoanomala aptenus Poinar & Vega is recognized as a junior synonym of Tingiometra yuripopovi Golub & Heiss, and the latter species is transferred to Paleoanomala as Paleoanomala yuripopovi comb. nov. The affinities of the male paratype previously assigned to this species remain uncertain and it is tentatively treated as Ebboinae indet. Finally, a synthesis of the palaeobiogeographical affinities of arthropods from Cretaceous Spanish amber suggests extensive faunal connections between Iberia, Myanmar and the Middle East during the Early Cretaceous, reflecting the widespread distribution of resiniferous forest ecosystems across Laurasia.

Phoebodus was recognized as the earliest elasmobranch known from articulated remains, a group which constitutes most modern cartilaginous fish comprising sharks, skates and rays. Its elongate body, the presence of two dorsal fins with fin spines, and the elongate head had already been described. Based on spectacularly well-preserved fossils, we add new anatomical information on its exact body proportions, the paired and caudal fins, the dermal denticles, the skull morphology, the endocast, and the gill skeleton. These new skeletons from the Famennian (Upper Devonian) of Morocco (c. 367 Ma) permit a much-improved reconstruction of the anatomy of Phoebodus. The new materials comprise the oldest elasmobranch specimens preserving the complete head in three dimensions. Additionally, the new materials yield information about growth and diet and thus position in the trophic network. Despite the newly coded characters, the phylogenetic position of the genus Phoebodus with the oldest teeth dating to the early Givetian remains that of the oldest stem-elasmobranch in the Bayesian analyses.

Highlights: 

• A full revision of Thai Nymphoides based on morphology and cytogenetic evidence is provided.

• Cytogenetic and morphological evidence supports Nymphoides species boundaries.

• Ten Nymphoides species are described in Thailand, including five new endemic species

Abstract 

A taxonomic revision of Nymphoides (Menyanthaceae) in Thailand was undertaken using cytogenetics and morphology. Specimens were collected throughout Thailand. Cytogenetic analyses were conducted on living collections. The morphological characters used in the descriptions of all taxa were measured from living specimens, which were subsequently maintained for ex-situ conservation. We provide a new generic description, a key to species, and descriptions of all species. Line drawings are provided for the five new species and color photographic illustrations are provided for all taxa. Herbarium voucher specimens were prepared and deposited in Thai herbaria. Ten species are recognized in Thailand, including five new species described in the present study for the first time, namely Nymphoides chumphonense, N. crucioides, N. miniata, N. thailandica and N. thungyaiense. Cytogenetic evidence supports the proposed species boundaries of Thai Nymphoides.
