Special Issue Information

Dear Colleagues,

We are delighted to announce a milestone achievement for Taxonomy—the journal has received its first Impact Factor of 1.5, ranked Q2 in the ZOOLOGY category and Q3 in the PLANT SCIENCE category, achieved a 2024 CiteScore of 2.4, and ranked Q2 in Agricultural and Biological Sciences: Agricultural and Biological Sciences (miscellaneous). The support and dedication of all the editors, reviewers, authors, and readers are an integral part of the journal’s performance.

To celebrate this exciting occasion, we are launching a Special Issue targeting innovative approaches and new developments in the field of taxonomy, systematics and nomenclature. We warmly invite you to submit your manuscripts to increase the visibility and impact of Taxonomy, and we look forward to your contributions.

Topics of interest include (but are not limited to) the following:

Taxonomy, evolution, and biodiversity;
Microtaxonomy and macrotaxonomy;
Morphospecies versus genetics;
Deep time diversity;
Identification and description of new species;
Citizen science in taxonomy.

Prof. Dr. Mathias Harzhauser

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Taxonomy is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The genus Raiamas currently comprises 18 valid species, only 2 of which occur in Asia; the remaining 16 are endemic to Africa. Raiamas harmandi was originally described by Sauvage in 1880 as Bola harmandi, which is distributed in the Great Lakes, Cambodia, the Mekong River Basin. It was considered a synonym of R. guttatus by later researchers. In this study, we examined 49 Raiamas individuals from the Mekong, Irrawaddy, and Salween river basins, recording both meristic counts and morphometric measurements. Based on the morphological evidence, we revised the taxonomy of Raiamas in the Mekong River Basin, confirming R. harmandi as a valid species and providing a comprehensive redescription. Raiamas harmandi can be distinguished from R. guttatus mainly by having more predorsal scales (25–28 vs. 21–23) and a different color pattern on the lateral body. Utilizing a total of 44 aligned COI and Cyt b sequences—including eight newly sequenced individuals of Raiamas from three river basins—we reconstructed its phylogenetic relationships. The analysis strongly supported four R. harmandi individuals from the Mekong River Basin forming a distinct clade, which was the sister to the clade comprising five R. guttatus individuals from the Irrawaddy and Salween river basins. Genetic distances between R. harmandi and R. guttatus ranged from 14.0 to 14.9% for COI and 16.1 to 17.0% for Cyt b. Distributionally, R. harmandi occurs throughout the Mekong River Basin, as evidenced by combined voucher specimens and molecular sequence data. Full article
