[Entomology • 2026] Attenboroughnculus tau • A New Genus of Pedunculinae (Hymenoptera: Ichneumonidae) from Chile and A Key to the World Genera


Attenboroughnculus tau De Ketelaere and Broad,

in De Ketelaere, Pullar et Broad, 2026.  

ABSTRACT
A new genus of Pedunculinae (Hymenoptera: Ichneumonidae) is described: Attenboroughnculus De Ketelaere and Broad, gen. n. a monotypic genus for Attenboroughnculus tau De Ketelaere and Broad, sp. n. collected in central Chile. This is the fourth genus and fourth described species of Pedunculinae and the second from the Neotropics. Each of the four known genera is defined by putative apomorphies, included in an identification key, and photos of each are provided.

KEYWORDS: Austral, Darwin wasps, Gondwanan, new species, South America, taxonomy, Sir David Attenborough


Attenboroughnculus De Ketelaere and Broad, gen. n.
  
Etymology: 
This unique genus from Chile has been named after Sir David Attenborough ahead of his 100th birthday, celebrating the broadcaster and biologist’s highly distinctive contribution to our understanding of the natural world. David Attenborough has featured Chile’s diverse, extreme landscapes in several documentaries, emphasising the unique environmental challenges and ecological resilience of species within the country.

Sir David has also filmed several scenes with parasitoid wasps, famously termed the ‘bodysnatcher wasp’ by the broadcaster in the Trials of Life, first broadcast in 1990. He has used his work to reveal the intimate, unseen or overlooked within nature. This resonates in the discovery of this species in an unsorted drawer within the collections of the Natural History Museum, London.

In 2023 Sir David revealed a new bronze quote outside the Natural History Museum, London, reading: The future of the natural world, on which we all depend, is in our hands. We are using this opportunity to echo this message through the naming of this new genus of tiny wasp.

We hope to inspire global scientists to take another look in their collections to see if there is something small that could contribute to our collective understanding and therefore the future of our natural world. The name is a concatenation of ‘Attenborough’ and ‘Pedunculus’.


Attenboroughnculus tau De Ketelaere and Broad, sp. n.

Etymology: Named after the large, capital ‘T’ marking on the second metasomal tergite, with ‘tau’ being the Greek for ‘T’. A noun in apposition.

[Herpetology • 2026] Pristimantis milpe Long overdue: A New, widespread, species of Pristimantis (Anura: Strabomantidae) from the Chocó region and the synonymy of Pristimantis subsigillatus


 Pristimantis milpe 
Ron, Paredes-Aguirre, Paucar, López, Apunte & Ortega, 2026 
 

Abstract
As currently defined, Pristimantis subsigillatus is a species of the P. lacrimosus species group distributed in the Chocó of Colombia and Ecuador, from lowlands to Andean foothill forests. Upon re-examination of the holotype of P. subsigillatus, we conclude that the populations currently ascribed to P. subsigillatus are not conspecific with the holotype. Instead, the holotype is conspecific with one of the syntypes of P. latidiscus, a species described four years before from a nearby locality. To avoid the ambiguity in the application of the binomen Hylodes latidiscus, we designate a lectotype. As a result, P. subsigillatus becomes a junior synonym of P. latidiscus. The misidentified populations represent an undescribed species which we describe based on morphological, bioacoustic, and genetic data as Pristimantis milpe sp. nov. The new species has one of the widest distributions among Chocoan Pristimantis and is unusual for having sexual dimorphism in coloration. It is most closely related to Pristimantis degener from which it diverged in the late Miocene and is morphologically distinct. The fact that such a common species remained “invisible” to taxonomy highlights the importance of correctly establishing the link between the name-bearing types and natural populations. Finally, we discuss how taxonomic treatments of Pristimantis during the second half of the 20th century often made this non-trivial error.

Key words: Andes, holotype, integrative taxonomy, lectotype, phylogeny, systematics



Pristimantis milpe sp. nov.

Common name. English: Milpe Rain Frog.
Spanish: Cutín de Milpe.

Diagnosis. We assign the new species to the genus Pristimantis based on the phylogeny (Fig. 5). Species of Pristimantis characterized by: (1) smooth to slightly tuberculate dorsal skin, areolate belly; discoidal fold evident; dorsolateral folds absent; (2) tympanum condition B; tympanic ring covered dorsally by supratympanic fold, tympanic membrane not differentiated; (3) truncate snout in dorsal view and protruding in lateral view; (4) upper eyelid generally without tubercles (occasionally one tiny tubercle present); (5) cranial crests absent; (6) oblique dentigerous processes of vomers; (7) vocal slits present, nuptial pads ...

Etymology. The specific epithet is a noun in apposition and refers to the type locality, the Milpe Bird Sanctuary, a private reserve in Pichincha Province, Ecuador. The sanctuary protects ~ 100 ha of Foothill Montane Forest and is part of the Andean Chocó, one of the most diverse and threatened regions on the planet. The Milpe Bird Sanctuary is managed by the Mindo Cloudforest Foundation, a non-profit organization dedicated to the conservation of biodiversity in the Andean Chocó. The Foundation maintains close relationships with local communities, promoting environmental education, sustainable livelihoods, and participatory management of natural resources. It also supports other private reserves and local Decentralized Autonomous Governments in forest restoration through the production of native plants in their nurseries, strengthening long-term conservation in the region.

[Botany • 2026] Cryptanthus pataxoanus & C. beuckeri • Two Ornamental Species of Cryptanthus (Bromeliaceae: Bromelioideae) on the brink of Extinction: A New Species and its congener from the 19th century

 

Cryptanthus pataxoanus  Forzza & Leme,

in Leme, Fernandez, Fontana, Almeida et Forzza, 2026. 

Abstract
The authors describe and illustrate a new species of CryptanthusC. pataxoanus, found within the Monte Pascoal National and Historical Park, and present new data on its closest morphological relative, C. beuckeri, both endemic to the Atlantic Forest of the state of Bahia, Brazil, and assessed as Critically Endangered (CR). The new taxon represents one of the most ornamental discoveries in recent years due to its marbled foliage, with contrasting greenish-yellow and dark green colors, which is similar to C. beuckeri. The main differences between C. pataxoanus and its closest relative include leaf blades not petiolate or the basal ones sometimes subpetiolate, the much broader portion of the blades distinctly longer, the narrower sepals covered by brown-centered trichomes, and petals without glandulose trichomes. The discovery of the new species results from cooperative work with the Pataxó indigenous community living in Barra Velha and Barra Velha do Monte Pascoal Indigenous Lands, located within the boundaries of the Monte Pascoal National and Historical Park. It symbolizes the inexhaustible richness of the Brazilian biodiversity in general and the Atlantic Forest of southern Bahia in particular, despite its current coexistence with high levels of threat.

 Cryptanthus pataxoanus Forzza & Leme, sp. nov.  

Diagnosis:—This new species can be distinguished from its morphologically closest relative, Cryptanthus beuckeri, by the leaf blades not petiolate or the basal ones sometimes subpetiolate, with subpetioles gradually merging into the much broader distal portion (vs. always distinctly petiolate, with petioles strongly contrasting with the much broader distal portion); the much broader portion of the blades longer (20–30 cm vs. 10–20 cm long); sepals with narrower lobes (vs. 2–2.5 mm vs. 3.5–4 mm wide) covered by distinctly brown-centered trichomes (vs. trichomes white); and petals without glandulose trichomes (vs. adaxially bearing glandulose trichomes).

Etymology:—The name of this new species honors the Pataxó indigenous people. They belong to the Macro-Jê linguistic family and have a long history of resistance, facing challenges such as reclaiming their traditional lands and promoting the value of their culture since the 16th century. The Pataxó predominantly inhabit the extreme south of Bahia, which includes the area of the Monte Pascoal National and Historical Park where the Barra Velha and Barra Velha do Monte Pascoal Indigenous Lands are located. They maintain strong traditions, such as the Patxohã language, rituals (like the Awê), and the use of body paintings that serve as cultural identifiers, in addition to promoting the conservation of the environment within their traditional natural territory.

Highlights: 
• New 9 gene molecular tree for 202 species of Neotropical electric knifefishes (order Gymnotiformes)
• A new taxonomy is proposed, based on the most extensive phylogenetic analysis to date.
• Strong phylogenetic support for 6 families, including the Electrophoridae (electric eels)
• Two main groups of species defined by either pulse or wave-type electric signals.
• Two new suborders: Pulseoidei for pulse-type species and Sinusoidei for wave-type species.

Abstract
The order Gymnotiformes—Neotropical electric eels and knifefishes—comprise a distinctive lineage of freshwater fishes characterized by electrogenesis and electroreception. Despite their ecological, evolutionary, and neurobiological significance, phylogenetic relationships within the order remain incompletely resolved. We present the most taxonomically inclusive molecular phylogeny of Gymnotiformes to date, based on two mitochondrial and seven nuclear genes from 202 species representing 31 of 36 extant genera. Maximum likelihood and Bayesian inference analyses provide strong support for a concordant species-level phylogenetic arrangement that we use to propose a revised classification of Gymnotiformes, including new suprageneric names and reassignments of some taxa and species. We found support for six monophyletic families, including Electrophoridae (electric eels). We propose two new suborders corresponding to electric signal type: Pulseoidei (pulse-type) and Sinusoidei (wave-type), an arrangement that does not allow determination of whether a pulse or wave-type signal was ancestral. In Apteronotidae, the subfamilies Sternarchorhamphinae and Apteronotinae are supported; within Apteronotinae, we establish the tribe Steatogenini to include Porotergus, Sternarchella, and close relatives. We resolve the non-monophyly of Apteronotus with generic reassignments. For Sternopygidae, we support the monophyletic subfamilies Sternopyginae and Eigenmanniinae and resolve polyphyly in Rhabdolichops and Eigenmannia via generic reassignments. Within Gymnotus, we support six species groups. We confirm the sister-group relationship between Hypopomidae and Rhamphichthyidae and clarify their internal structure, including support for six species groups within the diverse genus Brachyhypopomus. Our study provides a robust phylogenetic framework for Gymnotiformes and establishes a foundation for future work on systematics, biogeography, trait evolution, and comparative neurobiology.

[Herpetology • 2026] Isthmohyla nacientes • A New Species of Stream-Breeding Isthmohyla (Anura: Hylidae) from Costa Rica

 

Isthmohyla nacientes  
Chaves-Acuña, Abarca, Navarro-Picado, Hidalgo-Mora, Ureña-Chaves, Valverde-Castillo, Chaves, Bolaños & Faivovich, 2026
   

Abstract
We describe a new species of the Isthmohyla tica group that occurs along the montane regions of the central Pacific of Costa Rica, between 1,400 and 2,000 masl. Although the new species is the sister taxon of a clade including an unde-scribed species and I. rivularis, it is more similar to I. tica. However, the new species can be distinguished because the flanks have scattered, distinct, round and irregular dark blotches or spots and because the advertisement call is comprised by a single, tonal note, typically emitted singly or in series, at dominant frequencies of 4,048–4,909 Hz, with a duration of 10–50 ms. The new species exhibits a broad acoustic repertoire composed of advertisement, release, and courtship calls, with the latter being emitted underwater. We discuss our findings with respect to adult and larval morphology, reproductive biology, and bioacoustics of the I. tica group.

Etymology.—The specific epithet “nacientes” refers to the crucial role of headwaters and springs (nacientes in Spanish) in the habitat and life cycle of the new species and its stream-breeding congeners. This name highlights the species’ association with aquatic environments, particularly the springs found in its range, acknowledging the ecological significance of these water sources.

[Arachnida • 2026] Latrodectus lucacha • A New Andean Species of Widow Spider (Araneae: Theridiidae: Latrodectus)


Latrodectus lucacha  
 Miller, Kratzer & Griswold, 2026

 
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.

[Herpetology • 2026] Allobates tanaruThe 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


 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.

Allobates tanaru sp. nov. Dantas, Ferrão & Lima
  
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.”

Vernacular names: Tanaru's nurse frog (English),
Rana Cuidadora de Tanaru (Spanish),
Rãzinha Cuidadora do Tanaru (Portuguese).

Diagnosis: A nurse frog Allobates characterized by the following combination of characters. Small-bodied species, SVL 14.1–17.0 mm (n = 18) in males and 16.9–18.2 mm (n = 9) in females; granular dorsal skin; one subarticular tubercle on finger IV; tip of finger IV reaches the distal phalanx of finger III; cream dorsum with contrasting brown marks; dorsolateral stripe present; conspicuous ventrolateral line absent; translucent-white vocal sac; white ventral surface in males; white chest and belly in females; and dorsal surface of fingers brown.

Abstract
The Dendropsophus ruschii species group currently comprises two species with disjunct distributions between the Atlantic Forest and the Amazon. Based on an integrative approach combining morphological, acoustic, and molecular data (mtDNA barcoding), we describe a new species from the Serra da Mantiqueira, Minas Gerais, Brazil. Dendropsophus liliae sp. nov. is diagnosed by its small size, rounded digital discs, presence of a calcar appendage, dark red iris, and a distinct white stripe from the snout to the upper eyelid. This discovery expands the known diversity of the group and represents its most inland record within the Atlantic Forest.

Dendropsophus liliae sp. nov.  
   
Diagnosis.—We assigned the new species to the genus Dendropsophus and to the D. ruschii species group based on phylogenetic results (see Results below). In addition, the new species morphologically resembles other species of the D. ruschii group, especially D. ruschii, which exhibit white marks on the head and flanks. Dendropsophus liliae sp. nov. can be distinguished from its congeners within the D. ruschii group by the combination of the following features: (1) small size, adult males 16.0–19.5 mm SVL; (2) dominant frequency of the advertisement call from 6030 to 6630 Hz; (3) rounded discs on fingers and toes; (4) presence of sparse small granules on the dorsum; (5) presence of a calcar appendage; (6) eyes dark red; (7) overall dorsal coloration brown; (8) nuptial pad poorly developed; (9) wide head HW/SVL = 0.30–0.34; (10) a well-marked white line running from the posterior edge of the upper eyelid to the tip of the snout.

Etymology.— The specific epithet liliae is a patronym honoring Prof. Lília Maria Fraga Tostes (in memoriam) for her extensive contributions to biology education, her friendship, and her mentorship of DJS during his undergraduate studies. Prof. Lília, affectionately known as “Lilinha,” was a dear friend and a charismatic teacher widely known by the citizens of Muriaé, Minas Gerais (the hometown of DJS). Her kindness and charisma inspired many students to pursue careers in the biological sciences, and several of her former students are now professors who continue to carry her lessons forward.

[Botany • 2026] Valeriana umbellifera (Caprifoliaceae) • A New saxicolous endemic Taxon from Central Chile Mountains

 

Valeriana umbellifera A. Cádiz-Véliz, A.E. Villarroel & Nic. García, 

Cádiz-VélizGarcíaVillarroel et Zúñiga-Acevedo, 2026. 

Abstract
Valeriana, comprissing approximately 436 species, represents a successful evolutionary radiation within Dipsacales, with an important center of diversification in South America. In Chile, 46 species are currently recognized, 41.3% of which are endemic; two are reported as Endangered and one is probably extinct. The genus is mainly represented by herbaceous species, a calyx that is entire or modified into a pappus, a gamopetalous and pentamerous corolla, an inferior ovary, and an achene as indehiscent dry fruit. During botanical surveys in mountainous areas of Central Chile, specimens of a Valeriana restricted to crevices of steep rocky walls were found. Examination of herbarium material and relevant literature confirmed that it corresponds to a previously undescribed species, here named Valeriana umbellifera. This taxon is characterized by its perennial herbaceous habit, strictly saxicolous ecology, fleshy and glossy leaves arranged in a rosette, and a capituliform inflorescence with an umbel-like appearance. Its phylogenetic position was evaluated using molecular markers within the framework of previous analyses of Valeriana species from the southern Andes. According to IUCN criteria, we propose that the species be categorized as Endangered (EN) due to its restricted distribution, fragmented populations, and threats. The restricted distribution and ecological specialization of this new species underscore the conservation importance of rocky microhabitats in Central Chile, which are increasingly threatened by human activities.

[Botany • 2026] Sinningia pampeana (Gesneriaceae) • A New Species from the Pampa's rocky outcrops in southern Brazil and Uruguay

 

Sinningia pampeana G.E.Ferreira and Chautems, 
  
in Ferreira, Spiazzi, Barbieri, Chautems et Araújo, 2026.

Abstract
Sinningia pampeana is a new rupicolous species from the rocky outcrops of the Pampa biome in southern Brazil and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii. Sinningia pampeana is restricted to rock outcrops within the Pampa grasslands, where populations are threatened by grazing, habitat degradation, and potential mining activities. Given the current uncertainty regarding its distribution and sampling completeness, a preliminary conservation assessment of ‘Data Deficient' (DD) is proposed under IUCN criteria.

Sinningia pampeana G.E.Ferreira and Chautems sp. nov. 

Diagnosis: Sinningia pampeana differs from S. sellovii by its consistently red, horizontally oriented corollas (versus whitish pink to lilac or yellowish and pendent corollas), included anthers (versus exserted), a slightly bilabiate limb with enlarged dorsal lobes (versus a corolla tubular with subequal lobes), and the presence of only one to ca four flowers per bract axil (versus 3–9 flowers).

Etymology: The specific epithet ‘pampeana' refers to the Pampa biome, characterized by grasslands and rocky outcrops across southern Brazil, Uruguay, and Argentina. The name derives from the Quechua word ‘pampa', meaning ‘plain' or ‘open field'.
