Abstract
Montane forests of the Tropical Andes are among the most diverse and endemic-rich ecosystems in the world; however, they remain insufficiently documented, particularly in remote and topographically complex landscapes. Here, we describe Puya ukumari sp. nov. (Bromeliaceae), a new species from humid montane forests and forest–puna ecotonal habitats in the Kosñipata and Mapacho valleys of southeastern Peru, occurring at elevations between 2,300 and 3,300 m a.s.l. The species was first detected during a long-term ecological monitoring program in the region but remained unrecognized for several years due to the limited number of recorded flowering individuals. Its taxonomic identity became evident following the observation of flowering plants during field surveys conducted in 2025. Puya ukumari resembles P. lineata in possessing a simple, nodding, dark-colored inflorescence; however, it is readily distinguished by its considerably larger flowering plant height (160–200 cm vs. 40–80 cm), significantly wider inflorescence diameter (11–12.5 cm vs. 3.5–6 cm), larger lanate sepals (30–33 × 15–18 mm vs. 13–18 × 6–10 mm and floccose), and markedly darker, nearly black petals. These characters support its recognition as a distinct taxon within the group of Puya species with simple inflorescences. The species is currently known from a limited number of confirmed localities within a restricted elevational range. Based on its distribution and the observed threats to its habitat, a preliminary conservation assessment suggests that it should be classified as Endangered (EN) according to IUCN Red List criteria.

Puya ukumari Treviño, Yuca & Gouda, sp. nov.
 
Diagnosis. Puya ukumari is similar to P. lineata but is readily distinguished by its much larger flowering size (160–200 cm vs. 40–80 cm), significantly wider inflorescence (11–12.5 cm in diameter vs. 3.5–6 cm), and much larger sepals (30–33 × 15–18 mm vs. 13–18 × 6–10 mm), which are lanate in P. ukumari and floccose in P. lineata, as well as by its markedly darker petals (nearly black vs. blue).

Etymology. The specific epithet ukumari is a noun in apposition derived from the Quechua word “ukumari”, meaning Andean bear (Tremarctos ornatus). The species is dedicated to the Andean bear in recognition of the ecological importance of Puya species as a key component of its diet and of their close association within Andean montane ecosystems.

Cryptanthus pataxoanus  Forzza & Leme,

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

Abstract
The authors describe and illustrate a new species of Cryptanthus, C. 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.

Hoplocryptanthus serrapiresensis Leme, J.L.Lobo, O.B.C.Ribeiro & A.P.Gelli,

in Castro, Ribeiro, Leme, Almeida et Faria, 2025. 

Abstract
A new species of Hoplocryptanthus, a member of the bromelioid “Cryptanthoid complex”, is described based on plants discovered in a ferruginous rupestrian grassland located in the southern Iron Quadrangle region, Minas Gerais state, Brazil. Hoplocryptanthus serrapiresensis is endemic to the Pires Range, a region under strong threat by mining exploitation. The morphological characters of H. serrapiresensis are discussed in comparison with H. knegtianus and H. tiradentesensis. This microendemic species is assessed as Critically Endangered (CR), reinforcing the need for a strategy to protect the biodiversity of the region. Characters related to leaves proved useful in the taxonomic delimitation of this new species. Morphological analyses also validated and reinforced the diagnostic floral and inflorescence characters used in the circumscription of Hoplocryptanthus.

[Herpetology • 2026] Phyllodytes gravata • Another Piece in the Puzzle: A New Species of Phyllodytes Wagler, 1830 (Anura: Hylidae) from the Atlantic Forest of southern Bahia, northeastern Brazil


Image
 Phyllodytes gravata 
Santos, Rodrigues & Dias, 2026
 

Abstract
We describe Phyllodytes gravata sp. nov., a new species of bromeligenous treefrog from the Atlantic Forest of southern Bahia, Brazil. The new species is characterised by its small body size (males 19.5–22.0 mm snout-vent length; female 23.5 mm), a rounded snout with an apical tubercle, an inconspicuous row of tubercles along the tarsus, with a single prominent tubercle at the tibiotarsal articulation, a dorsolateral brown stripe, and an advertisement call composed of long series of pulsed notes (22–34 notes/call; call duration 5.2–7.3 s; dominant frequency 2.75–3.83 kHz). The species is currently known from only two nearby localities within the Central Corridor of the Atlantic Forest (CCAF), in the municipality of Porto Seguro, district of Trancoso, Bahia, a major tourist destination, where it inhabits bromeliads in sandy-soil ecosystems known as mussunungas. Its apparently microendemic distribution and strict association with bromeliads render it vulnerable to several anthropogenic threats, such as bromeliad harvesting, increasing tourism, urbanisation, and agriculture. This discovery underscores the persistent hidden diversity of the CCAF and reinforces the urgent need to protect its highly special microhabitats.

[Botany • 2026] Hechtia mixtecana (Bromeliaceae: Hechtioideae) • A New Species from Oaxaca, Mexico


Image
Hechtia mixtecana  Hern.-Cárdenas, Espejo & López-Ferr.,  

in Hernández-Cárdenas, Espejo- Serna, López- Ferrari, Lara- Godínez et Siekkinen, 2026. 

Abstract
Botanical explorations carried out in the state of Oaxaca, Mexico, led to the discovery of a new Bromeliaceae: Hechtia mixtecana,which is here described and illustrated. The new taxon is compared with the morphologically similar Hechtia fragilis, Hechtia lyman-smithii, and Hechtia minuta. Hechtia mixtecana differs from these taxa by the orientation of the leaves (ascending to divaricate), by the architecture of the staminate (twice branched) and pistillate inflorescences (once to twice branched), and by the length of the primary branches of the pistillate inflorescence (15–28 cm). A complete morphological description, images, and a geographic distribution map of the new species are included, as well as a list of examined specimens.

Hechtia mixtecana Hern.-Cárdenas, Espejo & López-Ferr. sp. nov.  

Diagnosis: Hechtia mixtecana is similar to H. fragilis but differs in the inflorescence of the staminate plants (twice branched versus once branched), in the presence of indument on its peduncle and floral bracts (glabrous versus lepidote), in the shape (elliptic versus broadly ovate to oblong) of the petals of the staminate flowers; in the length of the primary branches of the pistillate plants (15–28 versus 1–6 cm), and in the presence of indument on its floral bracts (glabrous versus lepidote).

Etymology: The specific epithet refers to and honours the Mixtec culture from Mexico. One of the regions occupied by the Mixtec ethnic group is located in northwestern Oaxaca, the area in which the type locality of the new species is found.

Abstract
A new Puya species, Puya vallis-colcaensis (Bromeliaceae, Puyopsis), that inhabits the high Andean region of Arequipa in southern Peru, is described and illustrated. This species has greenish-black petals, a compound inflorescence with branches measuring 11–15 cm long, floral bracts that turn dark when dry, and sepals with dense stellate trichomes, carinate toward the apex. This species was locally mistaken for the similar P. weberbaueri, but a comparative and detailed analysis of its morphology reveals that it should be considered a new taxon.

[Botany • 2025] Stigmatodon minimus (Bromeliaceae: Tillandsioideae) • A diurnal New Species of Stigmatodon from vertical rock walls of the Atlantic Forest inselbergs, Espírito Santo state, Brazil


Image
 Stigmatodon minimus  D.R. Couto & Leme,

in Couto, Manhães et Leme, 2025. 

Abstract
The authors describe and illustrate Stigmatodon minimus, a new species with the smallest stature within the genus, and discuss its taxonomic affinities and conservation status. Furthermore, this new species is the only one, among all others with typical tubo-laciniate stigma type, to present diurnal anthesis, reddish-wine to purplish-wine bracts, and unappendaged white petals, contrasting with the morphological characteristics of other previously known species of Stigmatodon s.str. The new species is closely to S. amadoi, with which it is compared, and considered a microendemic, Vulnerable [VU: D2] species due to its restricted habitat, reduced population size, and threats from ornamental rock mining.

Information on distribution, habitat and phenology is provided for each species. The new taxa are compared with P. jaliscana, P. karwinskyana, P. micheliana, P. palmeri, and P. pteropoda, species morphologically similar.  

Key words: Bromeliaceae, endemic, Monocots, Pitcairnia, Sierra de Huautla, Sierra de Mazamitla, Mexico

Pitcairnia aleserratoae Gonz.-Rocha, López-Ferr. et Espejo, sp. nov. 

 Diagnosis:—Pitcairnia aleserratoae is similar to P. micheliana but differs in the size of the spikes (16–27 cm vs. 12.5–25 cm long), in the indument of the abaxial surface of the peduncle and the sepals (densely white-lepidote vs. sparsely white-lepidote), as well as the shape of the petals (oblanceolate vs. narrowly elliptic to very narrowly oblong).

Etymology:—The specific epithet honors Dra. Alejandra Serrato Díaz (1972–2021) (Fig. 4A), professor who was in charge of Divisional Laboratory of Molecular Biology at the Universidad Autónoma Metropolitana-Iztapalapa. She always supported her students and contributed notably to the first author’s doctoral project, allowing that it was developed and concluded successfully.


Pitcairnia gracielae Gonz.-Rocha, López-Ferr. et Espejo, sp. nov.

Diagnosis:—Pitcairnia gracielae is similar to P. palmeri but differs in the indument of the photosynthetic leaves (sparsely white-lepidote on the margins vs. sparsely white-lepidote on abaxial surface), in the shape and size of the floral bracts (ovate, 4–11 mm wide vs. narrowly triangular, 2–5 mm wide), and in the orientation of the flowers at anthesis (secondly spreading to nutant vs. erect to ascending).

Etymology:—The specific epithet honors Dra. Graciela Calderón Díaz Barriga (1931–2022), professor and eminent botanist specialised in various families of angiosperms, whose dedication and constant work contributed significantly to the knowledge of Mexican Flora (Fig. 4B).


Pitcairnia pugana Gonz.–Rocha et P. Carrillo, sp. nov.  

Diagnosis:—Pitcairnia pugana is similar to P. jaliscana but differs in the inflorescence direction (curved vs. erect), in the size and indument of the peduncle (16–25 cm long, densely white-lepidote vs. 12–40 cm long, sparsely white-lepidote to glabrescent) and in the size of the peduncle bracts (12–29 cm long, barely surpassing the peduncle vs. 12–57 cm long, much longer than the peduncle).

Etymology:—The especies honors Luz María Villarreal de Puga (1913–2013) (Fig. 4C), an outstanding professor and dedicated botanist who carried out extraordinary work as a teacher and educator, and promoted studies on the flora and vegetation in the state of Jalisco for many years, and contributed noticeable in expanding the herbarium of Instituto de Botánica de la Universidad de Guadalajara (IBUG).

ABSTRACT
The Atlantic Forest domain is a biodiversity hotspot with remarkable amphibian diversity, including over 700 species, 70% of which are endemic. Most of these endemic species have restricted geographic ranges, often confined to mountainous areas, as exemplified by the leptodactylid genus Crossodactylodes. These frogs are characterised by small body sizes, a bromeligenous habit and limited dispersal abilities, with species often restricted to their type localities. Previous studies have revealed geographically structured lineages within the genus, even when separated by short distances. Here, we focused on a clade of Crossodactylodes comprising three lineages from southeastern Brazil, inhabiting montane forest ‘islands’ distinct from surrounding lowland areas regarding vegetation structure and microclimate. We integrated genetic, geographic, morphometric and qualitative morphological data to assess species boundaries through species delimitation analyses and validation procedures. This integrative approach provided evidence supporting the recognition of one lineage as a distinct taxonomic entity, which we formally describe herein as Crossodactylodes alairi sp. nov. Additionally, we applied coalescent simulations and supervised machine-learning approaches to evaluate alternative diversification hypotheses. Our results provide strong support for fragmentation models, suggesting that divergences within the focal lineages were driven by climate-related habitat fragmentation during the Plio-Pleistocene. Given that these lineages inhabit a non-macrorefugium region of the Atlantic Forest, their evolutionary trajectories were likely shaped by survival in isolated microrefugia that offered stable and suitable microclimatic conditions amidst broader environmental changes.

Crossodactylodes bokermanni—Almeida et al. (2011, 557 [their appendix 1], in part);
Montesinos et al. (2012, 112 [their appendix 1]).

Diagnosis. Crossodactylodes alairi is diagnosable from its congeners by the following combination of characters: (1) absence of vomerine odontophores; (2) adult males lacking vocal slits; (3) absence of dorsolateral fold; (4) inner metacarpal tubercle in adult males weakly widened; (5) discs of fingers II–IV slightly expanded; (6) hindlimbs lacking transverse bars; (7) skin on males dorsum coarsely granular; (8) SVL 17.2–18.6 mm (females) and 17.0–21.1 mm (males); (9) in life, iris uniformly dark brown or light brown with dark brown fine reticulations; (10) upper eyelid margin granular, with a pronounced tubercle in its medial region; (11) disc of Finger I rounded; (12) medial region of the upper lip not anteriorly projected.

Etymology. The specific epithet honours Alair Tedesco, a park ranger who worked at Parque Estadual do Forno Grande for 27 years, dedicating much of his life to conserving the region. Even in retirement, he continues to collaborate with researchers and visitors, enthusiastically sharing his vast knowledge of the area. 
Suggested common names: Alair's bromeliad frog (English); rãzinha-de-bromélia-de-Alair (Portuguese).
