Abstract
Southwest China is extremely rich in fungal resources, and a large number of new taxa have been discovered in recent years. In the present study, we examined 26 specimens of the genera Hydnum and Lentaria sensu lato, most of which were obtained in Yunnan Province. Through ITS-nrLSU-tef1 phylogenetic analysis, combined with morphological studies and geographic analyses, five new species were described, viz. Hydnum cremeum, H. flavoquamosumH. roseoalbumH. roseotangerinum, and L. subalpina. Furthermore, we also supplied new information on some known species, including host plants and new distribution records. We re-examined the holotype sequences of two known taxa, H. flabellatum and H. pallidomarginatum, treating H. flabellatum as a synonym of H. pallidomarginatum. Additionally, a key to Lentaria s.l. in China was provided.

Abstract 
This study designates a lectotype for and redescribes Thelphusa dehaani White, 1847, a Japanese primary freshwater crab species belonging to the potamid genus Geothelphusa Stimpson, 1858. Geothelphusa dehaani was described based on material exported to the Netherlands by von Siebold. Although the provenance of all his specimens is uncertain (they may be from several locations), our morphological comparison of the lectotype with fresh specimens led us to ascertain that it was almost certainly collected from Nagasaki, where von Siebold stayed. Two new Geothelphusa species are also described from Amakusa Islands and Aomori Prefecture.

Abstract
We describe Isodapedon varzealis gen. et sp. nov., a new hyperodapedontine rhynchosaur from the Carnian deposits of the Candelária Sequence, southern Brazil. Phylogenetic analyses place this taxon outside known South American hyperodapedontines, including Macrocephalosaurus mariensis and ‘Hyperodapedon’ species, and support the restriction of the genus Hyperodapedon to its type species, thereby revealing greater diversity within the group than previously recognized. Isodapedon varzealis gen. et sp. nov. is characterized by symmetrical maxillary tooth bearing areas and distinctive dentary morphology, indicating divergent feeding adaptations relative to known rhynchosaurs. Stratigraphic occurrence in beds correlated with the Exaeretodon sub-zone of the Hyperodapedon Assemblage Zone, and its phylogenetic affinities with early diverging hyperodapedontines from Argentina and Scotland, imply a geographically widespread radiation of conservative morphotypes across southwestern Gondwana. This study highlights the complexity of Late Triassic rhynchosaur evolution and underscores the importance of continued palaeontological investigation in refining the taxonomy, biostratigraphy and palaeoecology of this key herbivorous clade.

Isodapedon gen. nov.

Type and only species: Isodapedon varzealis sp. nov.

Etymology. The genus name is derived from the Ancient Greek ἴσος (ísos), meaning ‘equal’ or ‘the same’, as a reference to the equally wide tooth-bearing areas of the maxilla.


Isodapedon varzealis sp. nov.

Etymology. The species name refers to the locality of ‘Várzea do Agudo’ in which the specimen was collected.

Diagnosis. The holotype of Isodapedon varzealis is distinguished from all other known rhynchosaurids by the following unique combination of morphological traits (* asterisk denotes autapomorphies): maxilla divided into two tooth-bearing areas by a single longitudinal sulcus; equally wide maxillary lateral and medial tooth-bearing areas; same number (three) of longitudinal rows of teeth in both maxillary lateral and medial tooth-bearing areas; absence of lingual teeth in the medial surface of the maxilla; straight posterior margin of the parietal; sharp sagittal crest extending up to the posterior margin of the parietal; short and rounded ventral process of the squamosal; distinct posterior process in the squamosal; no contact between the lacrimal and palatine; ‘blunt’ and greatly reduced posteroventral process of the dentary; single dorsal blade in the dentary; medial shelf in the medial surface of the posterior portion of the dentary that does not reach half the length of the bone*; medial shelf separated from the dorsal blade of the dentary by a shallow groove; dorsal margin of the posterior portion of the dorsal blade extending markedly further dorsally than the posterior portion of the medial shelf at the level of the posteriormost lingual tooth; and single well-defined row of small, dorsally projected, closely packed lingual teeth in the dentary.

[Fungi • 2024] Mooraboolomyces wintlei (Mucoromycota: Mucoraceae) • A New Genus and Species from Victoria, Australia

  

Mooraboolomyces wintlei  C.P. Hull, A.S. Urquhart & A. Idnurm, 


in HullUrquhart et Idnurm. 2024. 

Abstract
A new genus and species in the Mucoromycota, Mooraboolomyces wintlei, was isolated into culture from leaf litter from a national park in Victoria, Australia, and is described. The strain reproduced asexually to form sporangia and sporangiospores, with no production of zygospores, and sequencing of its genome and analysis supported a heterothallic mode of reproduction. Phylogenetic analyses using five DNA regions placed the strain within the Mucorales and Mucoraceae, clearly distinct from previously described genera. This represents the second genus in this phylum that has been identified from Australia and that is currently unique to this country.

[Botany • 2024] Salvia tainingensis (Lamiaceae) • A neglected New Species from Fujian Province, China

 

Salvia tainingensis  Y.L.Gao, D.Xie & Z.L.Ning, 

in Xie, M.-H. Zhang, Dong, Gao, D.-G. Zhang et Ning,  2024. 
 
Abstract
A species could not be known to the world of science if it not be discovered and described, considerable number of new species are neglected due to the plant itself and some other external restricted factors. On the basis of morphological and molecular evidences, a new species previously identified as Salvia scapiformis is now described and illustrated as Salvia tainingensis, named after Taining County in Fujian Province, where it was discovered. S. tainingensis does not closely resemble S. scapiformis, but is more similar to Salvia glabrifolia and Salvia daiguii, which were once identified as S. scapiformis, in terms of leaf shape, apex, base, corolla color, and connective length. However, it can be easily distinguished from the latter two by its thinly leathery leaves, serrate leaf margins, densely villous or glabrescent leaf abaxial, and the X-shaped arrangement of connective and filament.

[Botany • 2024] Dipcadi mukaianum (Asparagaceae: Scilloideae) • Molecular Phylogenetic Reconstruction improves the Taxonomic Understanding of Indian Dipcadi and reveals A New Species from the bank of Hiranyakeshi River, Maharashtra, India

 

 
Dipcadi mukaianum Shelke, S.R.Yadav & Lekhak, 

in Shelke, Tamboli, Surveswaran, Yadav, Choo, Pak et Lekhak, 2024.

Abstract
Dipcadi (Scilloideae: Asparagaceae) is a genus of bulbous monocots with approximately 40 species, of which 13 occur in India. Species delimitation within the genus has been troublesome hindering a comprehensive phylogenetic analysis. The most recent phylogeny of the subfamily Ornithogaloideae included six species of Dipcadi only from Africa. Here, we reconstructed the phylogeny of Ornithogaloideae including 23 accessions comprising 13 recognized taxa (11 species and two varieties) of Indian Dipcadi. The phylogenetic analyses were based on nucleotide sequences of three plastid regions (rbcL, matK and trnL-F spacer) and one nuclear region (ITS). Pseudogaltonia clavata exhibited sister relationship to Dipcadi. Our combined nuclear + plastid dataset analyses revealed a monophyletic Dipcadi with five clades, Clade I-V. Clade I, II and III included mainly Indian species whereas Clade V included mostly African species. Clade IV comprised D. serotinum. Clade I included nine taxa including our newly described speciesD. mukaianum. The new species was phylogenetically placed with D. erythraeum, D. saxorum and D. ursulae. Morphologically, the species resembled D. montanum and D. ursulae but differed in characters such as tepal cohesion, number of ovules per locule and foul-smelling flowers. Clade II and III included 11 and six taxa, respectively. D. erythraeum which has a native range from Egypt to western India was found in Clades I and V. The widespread Dipcadi species, viz. D. erythraeum and D. serotinum showed polyphyly however, the monophyly of Dipcadi is established. Our studies suggest that additional molecular markers (plastid as well as nuclear) should be tested for their taxonomy utility. Further work on the historical biogeography of Dipcadi on the subfamily Ornithogaloideae with more genetic data will yield insights how aridification of the landscape would have shaped the evolution of the geographical clades.

[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. 


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 newly discovered landlocked shrimp, Caridina maeklongensis, new species, is described from the Mae Klong Basin, western Thailand. The morphology of the new species resembles C. sumatrensis, from which it differs in possessing a shorter rostrum with fewer dorsal teeth, a small number of very large-sized eggs, and a greatly reduced posteromedian projection on the distal end of the telson. The molecular evidence of the mitochondrial 16S rRNA gene also supports the species status of the newly described species. This is the fifth endemic species of Caridina known from Thailand. 

Key words. crustacean, landlocked freshwater shrimp, molecular phylogeny, taxonomy, Southeast Asia

Alpheus cangiopalus 
Marin & Thịnh, 2024


ABSTRACT
 The article describes a new species of the genus Alpheus Fabricius, 1798 (Decapoda: Caridea: Alpheidae), referring to the “Alpheus malabaricus” species complex, which is characterized by unusually long and thin fingers of minor cheliped (pereiopod I). Alpheus cangiopalus sp. n. was found to live exclusively in highly specific shallow water muddy lagoons located in deep anoxic mangrove swamps of the Cần Giờ Mangrove Biosphere Reserve in South Vietnam. Detailed morphological comparison with Alpheus malabaricus (Fabricius, 1775) and other taxa earlier synonymized with the former species are provided. The trophic position of the new species was evaluated based on analysis of δ15N/δ13C stable isotopes, and a discussion on other ecological features of the species is also represented in the article.

KEY WORDS: Crustacea, diversity, mangroves, communities, Asia, Indo-West Pacific.
