Summary: Many true species have been misclassified as widely distributed species due to difficulties in recognition. This study identified two unrecognized species of Sillago using an integrated approach of morphology and DNA barcoding. Genetic analysis and morphological comparisons confirmed the validity of these new species.

Summary: A new species of giant guitarfish, Glaucostegus younholeei sp. nov., is described based on 13 specimens collected from Cox's Bazar district of Bangladesh. The new species can be distinguished from congeners by its body color, wedge-shaped disc, long narrow bluntly pointed snout, and other morphological features. Phylogenetic analysis of DNA barcode sequences confirms its divergence from other congeneric species.

Summary: Based on morphological and molecular evidence, two new species from the Microhyla heymonsi species complex in central Vietnam have been described. The Truong Son Range in Vietnam holds the highest diversity of Microhyla genus, but faces the risk of habitat loss due to deforestation, emphasizing the need for further research to enhance conservation efforts.

Summary: The study revealed genetic diversity within the range distribution of Microhyla berdmorei, with a high number of haplotypes and intra-species genetic distances. This suggests the possible existence of a species complex or cryptic diversity within the South and Southeast Asian regions.

Summary: Eight Gram-negative, aerobic, motile with paired polar flagella and rod-shaped bacteria from tobacco fields in Yunnan, PR China were identified as Ralstonia genus. The strains showed high similarity to R. wenshanensis, R. pickettii, and R. insidiosa. Genome sequencing revealed the presence of new species within the genus Ralstonia. Based on the data, three new species names were proposed.

Summary: Two novel Rhodococcus strains, LHW50502(T) and LHW51113(T), isolated from marine sponges in Xisha Island, Hainan Province, PR China, represent two distinct species within the genus Rhodococcus. They are proposed to be named as Rhodococcus spongiicola sp. nov. and Rhodococcus xishaensis sp. nov., respectively. These strains share almost identical 16S rRNA gene sequences but show relatively low similarities with previously characterized Rhodococcus species.

Summary: Examination of fungal specimens collected in the Atlantic rain forest ecosystems of Northeast Brazil revealed many potentially new species of Glomeromycota, with two closely related fungi forming glomerocarps. Phylogenetic analyses indicated that these two fungi represent two divergent undescribed species in the family Glomeraceae, with one placed in the genus Dominikia and the other in a sister clade to the genus Kamienskia.

Summary: A new species of Cladonema, named Cladonema digitatum sp. nov., was identified in a laboratory aquarium in Fuzhou, China, based on its morphological characteristics and DNA barcoding. It has distinct features that differentiate it from other Cladonema medusae. However, species identification based solely on morphology is difficult due to the phenotypic plasticity displayed by C. digitatum. Therefore, updating information on the life cycle and DNA barcoding is necessary to improve the taxonomy of the genus Cladonema.

Summary: This case report describes a gastrointestinal basidiobolomycosis (GIB) caused by a novel Basidiobolus omanensis species in a 20-year-old male patient. The isolate showed high minimum inhibitory concentrations (MICs) to multiple antifungal drugs but low sensitivity to amphotericin B. Molecular identification is crucial for rare opportunistic fungi.

Summary: Based on the average nucleotide identity and digital DNA-DNA hybridization analysis, Strains LMG 7974T and LMG 8286T are proposed as novel species of the genus Campylobacter. Their 16S rRNA gene sequences show highest identity with similar species of the genus Campylobacter. The results support the classification of these strains as novel species.

Summary: The taxonomy of the genus Gonyaulax is challenging due to the conservative morphology of its thecate structure. However, cysts of Gonyaulax show variations in morphology and are related to fossil-based genera Spiniferites and Impagidinium. Through germination experiments, new species of Gonyaulax were identified and a well-resolved clade based on molecular phylogeny was formed. Additionally, low concentrations of yessotoxin were detected in one G. bohaiensis strain.

Summary: Ophiocordyceps species have a wide range of insect hosts, but only a few attack cicada nymphs. This study describes a new entomopathogenic fungus parasitic on cicada nymphs and another fungus parasitic on the larva of Coleoptera. Two new species, Ophiocordyceps hydrangea and Ophiocordyceps bidoupensis, are introduced based on morphology and multigene phylogenetic evidence. The phylogenetic analyses show that these two new species are distinct from other species of Ophiocordyceps.

Summary: For the first time, LSU and SSU sequences were obtained from four species of the marine planktonic diatom Planktoniella. Two new species, Planktoniella tubulata and Planktoniella trifurcata, were described based on a combination of morphological and DNA sequence data. The phylogenetic analyses showed that these four Planktoniella taxa formed a well-supported monophyletic group, with specific diagnostic characters identified for this genus. Detailed ultrastructural observations led to an emended description of Planktoniella.
