Strombus is a publication of the Conquiliologistas do Brasil (Conchologists of Brazil), publishing original scientific articles on all aspects of Malacology: systematics, paleontology, evolution, physiology, ecology, behavior, etc. Strombus has two issues per year, typically published jointly in December, now online only and fully open-access. Both research articles and research notes are accepted.


All manuscripts received will be peer-reviewed before publication. Manuscripts will be taken for revision only if they are not being concomitantly considered for publication elsewhere. Reviewers, normally two per manuscript, will have 30 days to complete their revision. If possible, the corresponding author should indicate at least three referees qualified to review their manuscript (and any potential referees to be avoided in case of competing interests).

Authors are asked to closely follow the guidelines below to avoid delay in the revision process. Manuscripts should be submitted by email ( as a Word document. Receipt will be readily acknowledged.

General Presentation

Manuscripts should be written in English. If English is not the first language of the author(s), please consider, prior to submission, a revision by a native speaker or a person well-versed in the language. Please note that language editing will not affect the decision on acceptance/rejection of the manuscripts. Both American and British English are accepted, as long as this choice remains constant throughout the whole text.

The manuscript should be submitted as a Word document. The text should be justified, with a 12-point font size of a commonly used (Times New Roman, Calibri, Arial, etc.), and line spacing 1.5.

Title: Bold, centered. Authorship of taxa should not appear in the title. When including high-ranking taxa, limit the number to two taxa, separated by a comma. Example: (Gastropoda, Helicidae).

Short running head: An abridged version of the title that appear on the top of the pages. Maximum 50 characters.

Author(s): First and last names should be spelled in full; middle names should be abbreviated. Affiliations should be indicated by numbers in multi-authored papers.

Abstract: Maximum 300 words.

Keywords: Up to five. They should not repeat the title.

Headings: Primary headings (Abstract, Introduction, etc.) should be in all caps, bold, centered. Subsidiary headings can be used; these should be justified, bold. Do not number headings.

Main text: The main text normally consists of Introduction, Material and Methods, Results (or Systematics), Discussion, Conclusion. The main text should be followed by the Acknowledgements, References, Figure Captions (if any) and Table Captions (if any). Footnotes should be avoided.

Use of hyphens and en-dashes: Hyphens should be used to link compound words and some prefixes. En-dashes (–) should be used to link spans, like size ranges, page numbers, figure numbers, and years.

Methodology: (1) The International System of Units (metric system) should be used. (2) Nomenclature and nomenclatural acts must be in agreement with the International Code of Zoological Nomenclature (4th ed., 1999). (3) Geological periods, epochs, ages and so on must be in accordance with the International Stratigraphic Chart (published by the International Commission on Stratigraphy). (4) When applicable, the methodology must be in accordance with international, national and/or institutional legislation and regulations for collection and/or ethical treatment of animals.

Voucher material: Authors are strongly advised to deposit voucher material in public museums or institutional collections. Registration numbers should be provided.

Nomenclature: The names of all genus and species level taxa should be italicized and authorship should be given (separate authors and year with a comma). For taxa that are the focus of the study, the original description should be listed in the References section.

Taxonomy: Headings of all taxonomic categories in taxonomy papers should be bold and centered. Synonymies should be presented in condensed format, in chronological order of usage. Diagnoses and descriptions must be presented in “telegraphic” taxonomic style, unless regular full sentences are needed for clarity or more detailed explanations.

Figures: Figures should be indicated in the text as “… (Figure 1)”, “… (Figures 1, 3, 5)” or “… (Figures 1–5)”. Figure captions should be placed at the end of the manuscript, after the References. All figures should be submitted in .jpeg or .tiff format, with a minimum resolution of 300 dpi. All figures must be prepared in a manner ready for publication (i.e., Strombus does not offer figure editing services).

Tables: Tables should be presented as separate Word or Excel documents. They should be referred to in the text as “Table 1” and so forth. Table captions should be placed at the end of the manuscript, after the Figure Captions.

Supplementary material: If necessary, supplementary files should be provided in appropriate format: a single pdf for text, tables, and figures; or separate files for large datasets, spreadsheets, videos, etc. They should be mentioned in the main text.


References in the text should be like:

“Smith (2001) said…”
“… (Smith 2001).”
“… (Smith 2000a, 2000b; Brown & Smith 2004; Smith et al. 2010).”

Note that authorship of taxa should have a comma separating the author’s name and the year.

The references should be listed alphabetically. Authors’ names should be in bold. Journal (and book) titles should be in italics and cited in full. When a book title contains a genus or species name, it should not be italicized. The format for each case is as follows:
