[Funga • 2024] Peniophora salaccae (Russulales: Peniophoraceae) • A Snake Fruit (Salacca zalacca) pathogen from southern Thailand

  

 Peniophora salaccae  Suwannar. S. Boukaew & J. Kamla, 

in Boukaew, Kamla et Suwannarach. 2024.  
 
Abstract
The genus Peniophora is known to be distributed from boreal to tropical regions worldwide. During surveys of plant diseases in southern Thailand in 2022 and 2023, two specimens of rotten snake fruits (Salacca zalacca) were collected. The new species, Peniophora salaccae, is described based on collections with morphological and molecular data. This species is characterized by orange-gray to brownish-orange basidiomes, simple-septate generative hyphae, brown lamprocystidia, subclavate to subcylindrical gloeocystidia, and subtriangular basidiospores. It can be distinguished from P. trigonosperma by its larger basidiospores and shorter lamprocystidia. Molecular phylogenetic analyses of the internal transcribed spacers (ITS) and the large subunit (nrLSU) of the nuclear ribosomal DNA (rDNA) confirmed the position of the new species within the genus Peniophora. The full description, color photographs, illustrations, and the phylogenetic tree showing the position of P. salaccae are provided. Additionally, pathogenicity tests showed that P. salaccae could infect snake fruits, which developed the same symptoms under artificial inoculation conditions as those observed in the field.

[Botany • 2023] Butia soffiae (Arecaceae) • A New Purple-flowered Butia from the Highlands of the Chapada dos Veadeiros (Brazil)


Butia soffiae   B.F.Sant’Anna-Santos,

in Sant`Anna-Santos. 2023.

Abstract
Background and aims – The highlands of the Chapada dos Veadeiros region comprise one of the largest savannah areas in central Brazil. The region includes large areas of the rare and little-known cerrado rupestre, which is home to numerous endemic species. During research on the Arecaceae flora of Chapada dos Veadeiros, a new species of Butia was discovered, and it is described here.

Material and methods – The morphology and anatomy are described based on field collections. Following the default methodology, pinnae and flowers were analysed using LM (freehand cross- and longitudinal sections) and SEM. The new species is compared to its morphologically similar species from the Brazilian central plateau, and an identification key and distribution map were established.

Key results – At first sight, the new species Butia soffiae resembles B. archeri, but with staminate and pistillate flowers, which are always purple, different in size, and congested in the rachillae. After close inspection, it is morphologically allied to B. buenopolensis, differing mainly by its glaucous peduncular bract – similar size to the inflorescence, herbaceous peduncle, numerous rachillae, purple floral colour, and inconspicuous staminodes. Differences in leaf anatomy, such as the presence of raphides, a cross-sectionally truncated midrib, and the number of accessory bundles on the midrib, also support the description of a new species. Two structures were recorded for the first time for the genus: squamiform trichomes at the base of the pistil and osmophores on the staminodes. The new species is assessed as Critically Endangered based on the restricted area of occurrence and anthropogenic threats.

Conclusion – Butia soffiae is the first endemic Butia species described in Chapada dos Veadeiros. The type population is located near Chapada dos Veadeiros National Park, which is the subject of a bill that aims to reduce its area by 73%. The discovery of this new species reinforces the uniqueness of the local flora and the importance of maintaining the park.

Etymology: The epithet honours Dr Patrícia Soffiatti, affectionately called Soffi by her friends and mentees. She is a Brazilian scientist and professor at the Department of Botany at the Federal University of Paraná (UFPR), mainly devoted to studying Cactaceae. Her deep knowledge of the environment where cactuses and palms cohabit and her expertise in plant anatomy were essential to the description of the newly acaulescent Butia and Syagrus species discovered by our team on the Serra do Cabral massif.

Etymology. Named in honor of Professor Aristea Alves Azevedo, one of the most prominent Brazilian botanists and the first woman hired as a professor by the Universidade Federal de Viçosa (UFV) in the 1970s. Recently, she received the Peter Henry Rolfs Medal of Merit in teaching, one of the UFV’s highest honours. She mentored many botanists in plant anatomy, an inarguable source for the taxonomy of Arecaceae. Moreover, her former mentees carry out relevant research in plant conservation in Brazil, including for several botanical families of the campos rupestres of Minas Gerais.

[Botany • 2023] Pinanga subterranea (Arecaceae: Arecoideae: Areceae) • A New Arecoid Palm from Borneo that Flowers Underground


Pinanga subterranea Randi & W.J.Baker, 

in Randi, Petoe, Kuhnhäuser, Chai, Bellot et Baker, 2023.

A new acaulescent species of Pinanga (Arecoideae: Areceae: Arecinae) is described and illustrated here. This remarkable new species is the first palm described as flowering and fruiting underground, highlighting Borneo as a hotspot for palm diversity.

Pinanga subterranea Randi & W.J.Baker, sp.nov.

Diagnosis: This species is superficially similar to P. tenacinervis J.Dransf. (1980) but can be easily distinguished by its solitary habit (vs. clustering in P. tenacinervis), stem, crownshaft and inflorescence that are usually subterranean(vs. all above ground), and erect, usually subterranean infructescence (vs. pendulous, aerial).

Etymology: The specific epithet “subterranea” is derived from the Latin word subterraneus, meaning “underground.” This reflects the position of the stem, inflorescences and crownshaft below ground level. 

Habitat: Mainly recorded from lowland mixed dipterocarp forest valleys and on slopes near streams. On clay soils on chalk, red clay soils, or sandy clay soils, up to 650 m elevation.

Vernacular nam: Pinang Tanah (Malay, West Kalimantan). Pinang Pipit, Muring Pelandok (Kendorih language, Central Kalimantan).Tudong Pelandok (Iban language, Sarawak).

[Botany • 2023] Syagrus carvalhoi (Arecaceae) • A New Bluish-leaved Syagrus from an overlooked OCBIL in the Espinhaço Range (Brazil)

 

Syagrus carvalhoi  B.F.Sant’Anna-Santos,

in Sant'Anna-Santos, Micheli, Carvalho et Soffiatti, 2023. 

Abstract
Background and aims – This study is part of ongoing research on the Arecaceae Flora of the Serra do Cabral, an isolated massif in the southwest of the Espinhaço Range in Minas Gerais State. Because of the isolation of the massif, the area has a rich biodiversity and a high level of endemism. While searching for populations of the rare and critically endangered Syagrus cabraliensis, a new bluish-leaved palm species was discovered and it is described here.

Material and methods – The new species’ morphology is described based on field collections. The pinnae were analysed using SEM and LM cross- and longitudinal sections following default methodology. In addition, we compared the species to S. cabraliensis and provided ecological notes and a conservation status assessment.

Key results – Syagrus carvalhoi resembles S. cabraliensis but they can easily be distinguished by morphoanatomical characters. Both species occur non-sympatrically in the Serra do Cabral, in contrasting microhabitats: S. carvalhoi in the southern quartzitic campos rupestres and S. cabraliensis in the northern ferruginous campos rupestres. A key to the known grass-like Syagrus species from the massif is provided. Based on the restricted area of occurrence and the anthropogenic threats, Syagrus carvalhoi is assessed as critically endangered.

Conclusion – Syagrus carvalhoi is the second grass-like endemic Syagrus species from the Serra do Cabral and presents rare characters within the genus (grass-like aspect, colonial habit, flowers in tetrads, and the stem forking at or below the ground). This discovery corroborates that this isolated OCBIL (old, climatically-buffered, infertile landscape) is a home for endemic and rare palm species. The Serra do Cabral massif has proved a source of morphological and anatomical novelties in Arecaceae, affecting the taxonomy and understanding of the evolution and ecology of palms. Our results reinforce the notion that it is important to conserve this area with rich and rare biodiversity but under alarming and unprecedented threats.

Syagrus carvalhoi B.F.Sant’Anna-Santos, sp. nov.
 
Diagnosis: Syagrus carvalhoi is similar to Syagrus cabraliensis (Noblick & Lorenzi) B.F.Sant’Anna-Santos, from which it differs by larger, taller clumps (sometimes with colonial habit); taller plants; leaves bluish and straight (vs dark green and slightly arched); pinnae inserted at various angles near the base but otherwise regularly arranged on the upper part of the leaf towards the tip (vs inserted at various angles throughout the entire rachis); pinnae with symmetric tip (vs asymmetric tip); pinnae glaucous on adaxial surface (vs pinnae glossy on adaxial surface); the presence of inconspicuous ramenta (vs without ramenta); rachillae of different sizes throughout the rachis (vs similar-sized rachillae); staminate flowers briefly pedicellate and filaments briefly connate at the base (vs staminate flowers long pedicellate and stamens with free filaments).

Etymology: The specific epithet carvalhoi is named in honour of Wellington Geraldo Oliveira Carvalho Júnior, a palm enthusiast who discovered this species. Mr Carvalho and his family have provided financial and logistical support to our research in recent years. So, our team’s discoveries were only possible thanks to his support and motivation.

cecak jarilengkung Obi | Obi Bent-toad Gecko || DOI: 10.1655/Herpetologica-D-21-00028 

Abstract
Based on phylogenetic and morphological evidence, we describe a new species of Cyrtodactylus from Obi Island in the northern Moluccas, Indonesia. The new species is genetically and morphologically allied to the Melanesian species Cyrtodactylus papuensis but is distinguished by its larger body size, fewer midbody scale rows, deep precloacal groove in males, and enlarged nonpored femoral scales and pored precloacal scales arranged in a continuous series. The new species is also genetically divergent from C. papuensis (p-distances of 19.0%–20.1% in the mitochondrial NADH dehydrogenase subunit 2 gene). Four species of Cyrtodactylus are now known from the northern Moluccas, but it is likely additional species remain unrecognized.

Cyrtodactylus papeda sp. nov.

Etymology.— The specific epithet is an invariable noun in apposition and refers to papeda (in Indonesian language), a traditional fiber-rich, cholesterol-low food in Moluccas and West Papua made from sago (Metroxylon sagu, family Arecaceae) starch. Here, we used this epithet to honor (promote) a traditional culinary feature of Obi Island and to showcase this new endemic gecko species to the public. Papeda is white in color, with the texture resembling sticky glue, and the cuisine is usually served with tuna fish and flavored with saffron. Suggested vernacular names are ‘‘cecak jarilengkung Obi’’ and Obi Bent-toad Gecko, in Bahasa Indonesia and English, respectively.

Abstract
Dryophthorinae is an economically important, ecologically distinct, and ubiquitous monophyletic group of pantropical weevils with more than 1,200 species in 153 genera. This study provides the first comprehensive phylogeny of the group with the aim to provide insights into the process and timing of diversification of phytophagous insects, inform classification and facilitate predictions. The taxon sampling is the most extensive to date and includes representatives of all five dryophthorine tribes and all but one subtribe. The phylogeny is based on secondary structural alignment of 18S and 28S rRNA totaling 3,764 nucleotides analyzed under Bayesian and maximum likelihood inference. We used a fossil‐calibrated relaxed clock model with two approaches, node‐dating and fossilized birth‐death models, to estimate divergence times for the subfamily. All tribes except the species‐rich Rhynchophorini were found to be monophyletic, but higher support is required to ascertain the paraphyly of Rhynchophorini with more confidence. Nephius is closely related to Dryophthorini and Stromboscerini, and there is strong evidence for paraphyly of Sphenophorina. We find a large gap between the divergence of Dryophthorinae from their sister group Platypodinae in the Jurassic‐Cretaceous boundary and the diversification of extant species in the Cenozoic, highlighting the role of coevolution with angiosperms in this group.

Bayesian topology with posterior probabilities (denoted by open red circle) of Dryophthorinae of the combined 18S and 28S aligned using primary and secondary structure. The analysis includes a broad sampling of 64 taxa, 2 platypodine outgroup taxa and 62 ingroup taxa representing all 5 tribes dryophthorine tribes and all but 1 subtribe Ommatolampina and a putative African lineage.
