•New Cyanobacterial species of Leptolyngbya genus isolated from Indian Ocean.•All Genome and 16S based analysis evidence qualifies this as a new species.•Species delineation supports ...polyphyletic nature of Leptolyngbya taxon.•The isolate shows unprecedented acid neutralizing ability.•The acid neutralization is more of a surface phenomenon.
An acid-neutralizing, filamentous, non-heterocytous, marine cyanobacterium named 'LK' has been isolated from the seashore of Bangaram Island, an atoll of Lakshadweep, India, and is described here as a novel species. LK has been characterized using morphological, ecological, and genomic features. Based on 16S rRNA, whole-genome sequencing, and marker gene-based analysis, LK has been identified as a new species. LK clustered with Leptolyngbya-like strains belonging to the LPP group but diverged from Leptolyngbya sensu stricto, indicating the polyphyletic nature of the Leptolyngbya genus. Leptolyngbya sp. SIOISBB and Halomicronema sp. CCY15110 were identified as LK's two closest phylogenetic neighbors in various phylogenetic studies. The analysis of 16S rRNA, ITS secondary structures, and genome relatedness indices such as AAI, ANI, and gANI strongly support LK as a novel species of the Leptolyngbya genus. The mechanism behind acid neutralization in LK has been delineated, attributing it to a surface phenomenon most likely due to the presence of salts of calcium, magnesium, sodium, and potassium. We name LK as Leptolyngbya iicbica strain LK which is a novel species with prominent acidic pH-neutralizing properties.
Cortinarius watsoneae, a new species in subgenus Myxacium, sect. Myxacium, is described from pine and mixed pine and hardwood forests from the Gulf States region of North America. It is characterized ...by the young lamellae that are grayish violet to pale violet, and relatively large basidiospores in comparison to C. mucosus. The ITS sequence is distinct from other members of sect. Myxacium, with 97% similarity to the closest known species, C. collinitus and C. mucosus. The new species is named in honor of the late Geraldine Watson.
Summary
Rhododendron starlingii Rushforth & Nguyen Thi Thanh Huong, from Fan Si Pan, Vietnam's highest mountain, is described as a new species and illustrated. It is related to R. crenulatum from Pu ...Bia, Laos' highest mountain, but differs in several characters.
Summary
The new species, Haemanthus humanii G.D.Duncan, is described. This extraordinary, winter‐growing, summer‐flowering dwarf geophyte is endemic to flats and undulating plains in the southern ...Namaqualand region of the Western Cape, South Africa. Details of its history, taxonomy, habitat and cultivation are given.
The myriapod fauna of China is still poorly known and very little attention has been paid to the study of Lithobiomorpha, with only more 100 species/subspecies hitherto known from the country, ...amongst which are only three species of Validifemur. Here we are describing a new species from northwest China.A new lithobiid species, Validifemur radispinipes sp. n., is described and illustrated from Wolong Mountain Park, Jingyuan County, Guyuan City, Ningxia Hui Autonomous Region, northwest China. The new species is compared with V. pedodontus Ma, Song & Zhu, 2007 from Shaanxi Province, China. Type specimens are deposited in the Institute of Myriapodology, School of Life Sciences, Hengshui University, Hengshui, China.
Trisetella pachycaudata, a new species in the subtribe Pleurothallidinae, was discovered in the Zamora Chinchipe province of southeast Ecuador, and it is described here. Trisetella pachycaudata is ...compared with the most similar species (and others with which it has been confused in cultivation), T. triglochin, T. strumosa, and T. vittata. It differs from them in the flowers with a much thicker apex of the sepaline tails (the thickest in the genus), and the petals expanded at the labellar margin, with the cuspidate apices erose on the upper margin and entire at the lower margin.
Key words / Palabras clave: Trisetella strumosa, Trisetella triglochin, Trisetella vittata, Zamora Chinchipe
Cuspidevia Jäch & Boukal, 1995 is a member of the tribe Macronychini which has the following features: antennae short, 6-10 segmented, aedeagus long and cylindrical, paramere very small, slender ...or lacking. This genus currently comprises only three species. All species are distributed in China.Cuspidevia pilosus sp. nov. is reported from Guangdong, Guangxi and Jiangxi Provinces in China. Habitus and diagnostic features of the new species are illustrated.
