Abstract

Anthiadidae, a family of shallow and deep-water reef-associated fishes, include about 250 species distributed widely from tropical to temperate regions, with the majority found in the tropical Indo-West Pacific (IWP). Despite their broad distribution, the phylogeny and taxonomy of this family remain unresolved, particularly at the generic level, due to challenges in sampling from deep-water zones. Plectranthias, the most species-rich genus, has been suspected of non-monophyly since its last revision over 40 years ago. In this study, we explore the phylogenetic relationships of anthiadids using a multigene dataset (one mitochondrial and four nuclear genes) from 103 specimens across 19 genera, with a focus on IWP Plectranthias. Our results confirm the polyphyly of Plectranthias, revealing seven distinct clades. Based on this new phylogenetic framework and morphological re-examinations, we propose a taxonomic revision, including the resurrection of the genera Pelontrus, Sayonara, Xenanthias, and Zalanthias, and the establishment of Aepysomanthias and Poroanthias Tang and Chen gen. nov. The revised taxonomy restricts Plectranthias to 20 currently recognized species.

[Botany • 2026] Habenaria adamantina (Orchidaceae) • Hidden in plain sight: A New Species from the Espinhaço Range in Minas Gerais, Brazil, plus an updated checklist of the Genus from Grão Mogol

 

Habenaria adamantina Cruz-Lustre & J.A.N.Bat., 

in Cruz-Lustre, et Batista, 2026. 

DOI: doi.org/10.5091/plecevo.165607 

 

Abstract

Background and aims – Habenaria is the largest genus of predominantly terrestrial orchids and the genus with the largest number of species in the family in Brazil. Field expeditions to Grão Mogol, in the northern part of the Espinhaço range of Minas Gerais, Brazil, led to the discovery of a taxon within the Habenaria nuda complex that could not be assigned to any of the known species within the complex. This study aimed to investigate the identity and taxonomic status of this taxon.

Material and methods – We analysed the morphology of the taxon and compared it with herbarium specimens of morphologically similar species. We assessed its phylogenetic relationships using parsimony, maximum likelihood, and Bayesian inference, based on nuclear (ITS and ETS) and plastid (matK-trnK and rps16-trnK) DNA sequences.

Key results – This taxon belongs to a large clade that mostly comprises species from the Cerrado domain. It differs from other species in the Habenaria nuda complex in that it has patent lateral sepals, and petal anterior segment and lip lateral segments that are shorter than the petal posterior segment and lip median segment, respectively. It also has small auricles located below the rostellum arms and anther canals. Based on these results, we described it here as a new species, Habenaria adamantina sp. nov. We present a distribution map, alongside comments on the taxon’s habitat, phenology, and preliminary conservation status, as well as an identification key to differentiate it from other species within the complex. The number of Habenaria species in Grão Mogol has increased from four to 12 species, with the new species being the only one restricted to the region.

Conclusion – This study highlights the importance of both continuous and group-specific botanical surveys for documenting biodiversity, particularly for species that are seasonal, inconspicuous, or present in low numbers.

Habenaria adamantina Cruz-Lustre & J.A.N.Bat., sp. nov.

 

Diagnosis: Habenaria adamantina is morphologically similar to Habenaria australis J.A.N.Bat., A.A.Vale & Menini in its small auricles, but it can be distinguished by the patent lateral sepals (vs deflexed in H. australis) and by the insertion of the anterior petal segment at the base of the posterior segment (vs 3.0–3.5 mm above in H. australis). It is also similar to Habenaria egleriana, Habenaria sobraliana J.A.N.Bat., A.A.Vale & Menini, and H. sprucei in that the anterior segment of the petals and the lateral segments of the lip are shorter than the posterior segment of the petals and median segment of the lip, respectively. However, it differs in that the auricles are arranged below the rostellum arms and the anther canals.

Etymology: The specific epithet is derived from the Latin “adamas”, meaning “diamond”, and refers to the abundance of these crystals in the Grão Mogol region, which was a major diamond mining area in the late 18th and early 19th centuries (Karfunkel et al. 1994; Chaves et al. 2006).

[Botany • 2026] Peperomia kauaiana (Piperaceae) • A New alternate-leaved Species from Kaua‘i, Hawaiian Islands and Notes on two possibly extinct Hawaiian Peperomia

Peperomia kauaiana  K.R.Wood & W.L.Wagner, 

in Wood, Wagner, et Fawcett, 2026. 

DOI: doi.org/10.3897/phytokeys.269.173971

 

Abstract

A new species of Peperomia with alternate leaves from Kaua‘i, Hawaiian Islands, is described and illustrated, with notes on its conservation status, distribution and ecology. We present a dichotomous key to all five Hawaiian Peperomia species with alternate leaves and include notes on two possibly extinct Hawaiian Peperomia species, namely P. degeneri and P. subpetiolata. Peperomia kauaiana sp. nov. differs morphologically from its Hawaiian congeners by its unique combination of diminutive leaves 5–14(–18) mm long, 4–11(–14) mm wide, palmately 5- to 7-nerved, ovate to ovate-orbicular with margins revolute, petioles 2–5 mm long and spikes 11–17(–22) mm long. Plants have been documented in three distinct windward Kaua‘i locations to date, including the southern ridges of Wahiawa, the central ridges of Wai‘ahi and the north-eastern ridges of the Makaleha Mountains. Peperomia kauaiana represents a newly-described wet forest species endemic to the island of Kaua‘i and is currently in need of conservation. Its discovery raises the total number of endemic Hawaiian Peperomia species to 24 and single-island endemic Peperomia on Kaua‘i to three.

 Peperomia kauaiana K.R.Wood & W.L.Wagner, sp. nov.

 

Diagnosis. Peperomia kauaiana is morphologically most similar to P. degeneri Yunck. from which it differs by the following combination of characteristics: stem internodes 3–5 mm long (vs. 10–15 mm long), leaves 5- to 7-nerved, ovate to ovate-orbicular, 0.5–1.4(–1.8) cm long, margins revolute (vs. leaves 3-nerved, elliptic to oblong-elliptic, 1.5–2(–3.5) cm long, margins flat), petioles 0.2–0.5 cm long (vs. petioles 0.8–1.2 cm long) and spikes 1.1–1.7(–2.2) cm long (vs. spikes 2.5–4.8 cm long).

Etymology. The epithet refers to the island of Kaua‘i, oldest and most floristically rich of all the high Hawaiian Islands and the only known location for Peperomia kauaiana.

Vernacular name. ‘Ala‘ala wai nui is the Hawaiian name for related species. Hawaiians used the ash of their burned leaves and stems as a grey-green dye in kapa making (Krauss 2001).

Abstract

A new species of Nepenthes—Nepenthes erucoides—is described and illustrated from a single ultramafic peak in the Dinagat Islands Province of northeastern Mindanao. It is a distinctive component of a relatively low-elevation, highly biodiverse montane elfin forest that has evolved in association with a particularly thin and extremely hostile substrate. Plant habit, and leaf, inflorescence, indumentum and peristome-column morphology appear superficially similar to those of the ultramaficolous montane species of Palawan, implicating an environmental basis for a syndrome of shared characteristics.

Taxonomy

 Nepenthes erucoides A.S.Rob. & S.G.Zamudio, sp. nov. 

Etymology:— The specific epithet erucoides is derived from the Latin eruca (caterpillar) and the Greek suffix – oides (resembling), in reference to the densely hairy developing leaves which, when still appressed within the petiolarlaminar groove of the preceding leaf, resemble the exuberantly hairy caterpillars of certain erebid macromoths from the subfamily Arctiinae, such as those of the genus Arctia Schrank (1802: 152) [e.g. Arctia opulenta Edwards (1881: 38)].

[Botany • 2024] Megastigma acarrilloi (Rutaceae) • A New Species from Sinaloa, Mexico, with the northernmost distribution of the genus

Megastigma acarrilloi Pío-León,

in Pío-León, 2024. 

DOI: doi.org/10.21829/abm131.2024.2406 

Abstract

Background and Aims: The genus Megastigma has six described species of shrubs distributed from Colima, Mexico, to Nicaragua. Through a routine review of the iNaturalistMX platform in 2023, a record of an individual of the Megastigma genus was observed, although in a very disjunct locality with respect to known species. The collection and subsequent review of the specimens allowed us to determine that it was a new species for science.

Methods: Botanical explorations and collections were carried out during 2023 and 2024 in the Sierra de Barobampo, municipality of Ahome, Sinaloa, Mexico. The identity of the species was determined by the review of specialized literature. A map with the distribution of each species of the genus was elaborated using the available data in digital repositories and specimens in the MEXU herbarium. The conservation status of the new species was evaluated and proposed according to the IUCN criteria. An identification key is provided for all species of the genus Megastigma.

Results: Megastigma acarrilloi is endemic to northern Sinaloa, Mexico, and has the northernmost distribution of the genus. The species with the closest morphological affinity is M. morenoi, which is endemic to Colima, from which M. acarrilloi differs because it is glabrous and has fewer leaflets per leaf. During the explorations, Lepidopteran larvae of the genus Papilio were observed feeding on its leaves. It is recommended to include M. acarrilloi as a Vulnerable species (VU) on the IUCN Red List.

Conclusions: With the new species, the genus Megastigma is now integrated by seven species, all present in Mexico, and of which six are endemic to the country. Megastigma acarrilloi also represents the first record of the genus for Sinaloa and north of the Trans-Mexican Volcanic Belt.

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.

Abstract

Knowledge of the diversity of Curcuma species in mainland Southeast Asia remains incomplete, and Vietnam is no exception. To address this gap, we conducted extensive field surveys throughout the country to document native taxa and clarify previously uncertain records. As a result of these efforts, we described and illustrated a new species, Curcuma fibrifera Boonma, D.D.Nguyen, Saensouk & P.Saensouk. In addition, we confirm the presence of three further species, C. comosa Roxb., C. petiolata Roxb., and C. phrayawan Boonma & Saensouk, in Vietnam for the first time, and we correct the prior misidentifications. To complement the taxonomic findings, we applied species distribution modeling to evaluate both current and future suitable habitats for these taxa under low- and high-emission climate scenarios. The inclusion of these species raises the total number of Curcuma subgenus Curcuma in Vietnam to 16, though actual diversity may still be underestimated. Full taxonomic accounts are provided for the new species and newly verified records, covering morphological descriptions, distribution, habitat preferences, phenology, taxonomic affinities, traditional uses, and conservation status. This study contributes a more comprehensive account of Curcuma diversity in Vietnam, supports conservation planning, and identifies priorities for further taxonomic and ecological investigations.

Curcuma fibrifera Boonma, D.D.Nguyen, P.Saensouk & Saensouk, sp. nov. 

Diagnosis: Curcuma fibrifera is similar to C. wanenlueanga Saensouk, Thomudtha & Boonma (Saensouk et al., 2021c, 2025b) in having terminal inflorescences, coma bracts, epigynous glands, spurred anthers, and flowers of the gullet type, but differs in having rhizomes ovoid to subglobose, 3–4 × 3–4 cm, ivory to cream (vs. ovoid, 5–9 × 3–5 cm, yellow); branches rhizome internal ivory with cream core, fibrous threads visible when broken (vs. yellow with darker yellow core, no fibrous threads when broken); leafy shoot 60–85 cm tall (vs. 100–150 cm); leaf sheaths 15–32 cm long (vs. 10–60 cm); petiole 5–13 cm long, green (vs. 15– 35 cm long, green with reddish tinge); lamina lanceolate to elliptic, 28–45 × 8–14 cm, base cuneate to rounded, midrib green (vs. narrowly lanceolate, 50–70 × 15–18 cm, base attenuate, midrib reddish-purple, fading with age); peduncle 20–24 cm long (vs. 30–40 cm); lateral staminodes asymmetrical ovate, apex obtuse to acute, 1.4–1.6 × 1.0 cm (vs. irregularly obovate, apex rounded, 1.3–1.4 × 0.7–0.8 cm); filament 3.2–3.5 mm long (vs. ca. 4 mm); anther spurs narrowly conical, ca. 1.5 mm, curved inward (vs. ca. 4 mm, pointing downward); and ovary oblate, 3–4 × 2 mm (vs. subglobose, ca. 3 × 3 mm).

Etymology: The specific epithet “fibrifera” is derived from the Latin words fibra meaning “fiber” and fero, ferre meaning “to bear, to produce, to carry.” Thus, fibrifera means “bearing fibers” or “producing fibers,” in reference to the characteristic fibrous threads that appear when the branches rhizome is broken, resembling the breaking of the petioles of Nelumbo nucifera Gaertn.
