Instructions to Authors
Folia Malacologica is published quarterly as an international journal devoted to all aspects of malacology. It publishes only the authors' original papers which have not been printed elsewhere (except conference abstracts) and are not under consideration for publication elsewhere. The language of publications is British English.

Folia Malacologica makes every effort to meet the standards of the editorially independent journal. The journal is financially independent, supported by subsidies from the Polish Ministry of Science and Higher Education, obtained on the competition route, used for electronic service of editorial work and digitalisation of published papers. Every effort is made for the efficient management and training of editorial and advisory boards, as well as of editorial and publishing staff.

1. Publication Ethics and Publication Malpractice Statements
Folia Malacologica has adopted and applies the principles of publication ethics in accordance with the guidelines of the Committee on Publication Ethics (COPE) (see:

It is necessary to agree upon standards of expected ethical behaviour for all parties involved in the act of publishing: the author, the journal editor, the peer reviewer and the publisher.

1.1. Publication
All submitted manuscripts are initially evaluated by Editors according to the following criteria: compatibility of paper topic with journal policy, paper originality, importance and timeliness.

The manuscripts with insufficient scientific priority are rejected. The other manuscripts are sent to at least two expert referees for peer review. Double-blind review process is used: peer referee identities are kept confidential for authors, author(s) identities are kept confidential for peer referees. The existence of a paper under review is not revealed to anyone other than peer referees and editorial staff. Final decision is made by Editors after receiving all referee opinions. After the final decision the referee identity may be exposed on his/her request. The authors are informed about paper acceptance or rejection within about three months.

1.2. Authors
It is assumed that all people listed as authors of submitted manuscripts meet both basic authorship criteria: (1) they contributed substantially to study planning, data collection or interpretation of results; and (2) wrote or critically revised the paper. It is also assumed that all people listed as authors are aware of it and have agreed to be listed. On the other hand, it is assumed that no person who meets the authorship criteria has been omitted.

Therefore, the manuscript submitted for publication must be sent with signed statement by corresponding author on behalf of all authors that the manuscript is their original work, it has not been published or is submitted for publication in any other journal, they all agree to be listed as the authors and there is no conflict of interests between all authors and any other party. At the editorial office's request the corresponding author should certify that all authors fulfill standards for authorship and declare their contribution to the manuscript. The corresponding author should also declare that the research has not been submitted for publication nor has it been published in whole or in part elsewhere.

Authors will be required to assign copyright of their paper to the Association of Polish Malacologists. Copyright assignment is a condition of publication and papers will not be passed to the publisher for production unless copyright has been assigned. Each author will automatically receive a copy of the copyright assignment form with Author's warranties to fill it in when his paper is accepted for publication.

Moreover, all people who are not listed as authors but contributed substantially to the study reported in submitted manuscript or assisted in its writing (e.g. language professionals) should be mentioned in the acknowledgements. Finally, sources of funding for the study reported in the submitted papers should be revealed.

It is assumed that all experiments on animals conform to ethical standards and those experiments on legally protected molluscs or in protected areas have been carried out by the authors who have got all necessary permissions. The permission must be declared by the authors during the process of paper submission.

Acting against the above rules, especially every reported or discovered case of scientific misconduct (ghostwriting, guest authorship, copyright infringement, plagiarism, self-plagiarism, etc.), will be treated seriously by Editors in accordance with the COPE guidelines. They will investigate the case and inform scientific bodies and/or employers of dishonest authors about it. The authors while submitting manuscript must confirm that they accept the above rules (especially those concerning ghostwriting and guest authorship). It is required to fill in and sign an appropriate form generated automatically by the system. Lack of confirmation will exclude their paper from further editorial proceedings.

1.3. Reviewers
Any manuscripts received for review must be treated as confidential documents. Reviewers must not use unpublished information and data in their own research and publications, neither transfer them to others.

Reviews should be conducted objectively and presented clearly with supporting arguments, so that authors can use them for improving the paper.

Reviewers should not review manuscripts when they have conflicts of interests resulting from competitive, collaborative, connections, companies or institutions connected to the publication.

Any selected referee who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the editor and excuse themselves from the review process. Any conflict of interests that may influence paper’s findings, conclusions, or referee’s opinion to the extent that they could be unreliable must be excluded.

1.4. Editors
Editors have complete responsibility and authority to reject or accept an article and are responsible for the content and quality of the publication. The editors must not use unpublished information in the editor's own research.

All unpublished manuscripts and annexes sent to Folia Malacologica are treated by editors as confidential documents.

Editors should preserve the anonymity of reviewers and ensure that all research material they publish conforms to ethical guidelines internationally accepted.

At any time, an editor must evaluate manuscripts for their intellectual content without regard to the nature of the authors or the host institution including race, gender, sexual orientation, religious belief, ethnic origin, citizenship, or political philosophy of the authors.

Editors should always discuss the reviews with authors permitting them to present their point of view, including possibility of the discussion with the reviewers.

Editors should always consider the needs of the authors when attempting to improve the publication and should publish errata pages or make corrections when necessary.

1.5. Complaints and appeals
Any case of complaints, appeals or reservations against the journal, its staff, editorial board or publisher (including actions incompatible with the above rules) should be reported to the editor-in-chief or the president of the Association of Polish Malacologists. They will be treated with due seriousness and the author of the complaint will receive a reply no later than three weeks from the date of notification.

2. Preparation of manuscripts
Once the submission materials have been prepared in accordance with the Instructions to Authors, manuscripts must be submitted online at the Folia Malacologica webstite ( Exceptionally they may be sent directly to ­editor-in-chief. When submitting a paper the following data should be sent to the editor: author’s full name(s), institutions, address (including ORCID, telephone number and e-mail address, as applicable). When submitting a paper with multiple authors, one author must accept the responsibility for all correspondence (as a corresponding author).

Manuscripts should be typewritten (Times New Roman font, size 12), double-spaced with margins of 2.5 cm in PC-compatible format. Please submit a manuscript with tables, figure captions and figures. The final version (revised after the review process) accompanied by original illustrations must be submitted also electronically. While preparing the final copy, use the following conventions: use tab commands, not spaces for paragraph indents. All character attributes in the text should appear in the file just as they will in the final printed paper (consult recent issue for internal style conventions), i.e. items to be set in small capitals, bold, italic (use italic font instead of underline), subscript and superscript should be formatted as such. All these attributes should be done using standard word processor's commands, avoiding procedures that are not convertible. The entire text file with references, should be justified to the left, including headings, subtitles etc.

Papers must conform to the following rules:

2.1. Title page
This should include title, abstract, key words and running head. The title should be concise but informative and, where appropriate, should include the names of families and/or higher taxa covered in the paper.

2.2. Abstract
The abstract should be informative, concise, and in a form that is fully intelligible in conjunction with the title. It should not exceed 300 words and should not include citation of references or reference to figures and tables in the text. Names of new taxa and indication of taxonomic acts (synonymies, new combinations, lectotype designations etc.) should be included.

2.3. Table of contents
For larger papers (over 100 manuscript pages) authors are requested to submit a "Table of Contents".

2.4. The standard arrangement
The standard arrangement for the research papers is as follows: Introduction, Material and Methods, Results, Discussion, Acknowledgements, References. In justified cases authors may depart from the above scheme. Subheadings may be used. Submitted manuscript in Material and Methods section should report study design allowing for reproducibility of results. If nucleotide sequences are analysed they should be deposited in official resource like GenBank of the National Center for Biotechnology Information (NCBI).

2.5. Generic and specific names
Only genus- and species-level names should be italicized. The International Code of Zoological Nomenclature must be strictly followed. Papers including new taxonomic decisions on previously described taxa (synonymies, new combinations, lectotype designations etc.) must include bibliographic data of the original description of the taxon (including page number). Use SI units and appropriate symbols.

2.6. Footnotes and cross references
They should be kept to a minimum.

2.7. References
References in the text should be cited in small capitals: Snailstone (1999); (Snailstone 1999) or Snailstone & Slugwater (1999: 303); for references with more than two authors use the form: Clamshell et al. Multiple references of various authors and references of the same author should be arranged in chronological order: (Snailstone 1802, Clamshell 1841, 1853, 1857, Veligersson 1919, 1922, Abalone 1999).

In the reference list references should be listed alphabetically with book and journal titles given in full. It is desirable to add a DOI (digital object identifier) number. Internet resources could be cited with exact URL link and date of accession. Each two references in the list should be separated by a blank line.

2.10. Illustrations
All illustrations are referred to as "Fig., Figs" in the text (not as plates or photos). Figure captions should be typed on a separate sheet, numbered consecutively. Submitted illustrations should be in *.pdf or *.jpg format. Illustrations may be mounted in plates in the arrangement desired in the printed work. If plates are prepared, particular figures should be numbered consecutively as e.g. Figs 1-3, not as Fig. 1A-C, etc.

After acceptance, the authors will be asked to provide the figures prepared in a format suitable for printing:
  • Figures prepared in MS Excel, MS Word and CorelDraw should be submitted in the original format of the given programme. Figures prepared in CorelDraw should not be saved as *.tif or *.jpg.
