Scope and policy

Nauplius is an electronic open access journal that publishes original research dealing with any aspect of crustacean biology. Papers are published in English only. Since 2016 papers are published as soon as accepted, under a continuous publication system.

Nauplius accepts three types of manuscripts for publication: Original Articles, Reviews, and Short Communications. All three types of contributions will be subject to the full editorial process.

Nauplius does not impose limitations on the number of pages for manuscripts, although Short Communications should be restricted to a few pages (usually, up to six pages).

When submitting a manuscript, please state in the cover letter that (1) the manuscript has been submitted solely to this journal and is not published, in press, or being considered for publication elsewhere; (2) that all research meets the ethical guidelines, including adherence to the legal requirements of the country where the study was conducted; and (3) that the manuscript is approved by all authors.

All manuscripts published in Nauplius are peer-reviewed for content and presentation by at least two appropriate referees, an editorial board member, and the editor.

Nauplius is part of the Scientific Electronic Library Online – SciELO and, as such, follows the SciELO Brazil Collection policies and criteria, as well as endorses the policies and practices recommended by the Committee on Publication EthicsCOPE.

Nauplius follows the requirements of Article 8 of the International Code of Zoological Nomenclature and all articles published have fixed content from the moment of their publication date. An eventual change to an article will only be permitted through the publication of an erratum.

Open Access Policy

This journal provides complete and immediate open access to its content.


All content of the journal, except where identified, is licensed under a Creative Commons attribution-type BY.

Upon publication of the manuscript in Nauplius the authors agree that the copyright is transferred to the Brazilian Crustacean Society.


There are no page charges or processing fees for authors. All costs are paid by the Brazilian Crustacean Society (SBC). Authors other than Society members are welcome to publish their research.

Upon acceptance, authors will receive proofs by PDF attachments to email messages. Authors must correct and approve proofs promptly in accordance with instructions received with the proofs. If proofs are not returned on time, the article will be withheld.

Nauplius is a non-profit scientific journal and to help keep Nauplius free to authors and readers upon the publication of the manuscript, authors are kindly invited to contribute a donation on the journal’s webpage.

Editors and journal staff as authors

Editors and members of the Nauplius editorial board are excluded from publication decisions in the event that one of them takes part in the authorship of a manuscript.

Form and preparation of manuscripts

Text Formatting:

  • All manuscripts must be submitted as .doc or .docx files.
  • The original of the manuscript must be left-aligned (except title, centered), double-spaced, all margin 2.54 cm (1 inch), 12 pt Times New Roman font.
  • Do not use footnotes.
  • Italics should be used only for (a) scientific (genus or species/subspecies) names, (b) subheadings of sections; (c) statistical symbols, variables/constants in formulae; and (d) code for genes. Boldface is used in (a) section headings; (b) names of taxonomic ranks (including genus and species names) followed by their respective authority used as centered subheadings of the “Systematics” section before the taxon description; and (c) optionally as headings of table columns.
  • Latin phrases should be in normal font, not in italics (e.g., et al., i.e., sensu stricto, etc.).
  • Nauplius uses the International System of Units – SI (the metric system) base units as well as the non-SI units that are accepted for use with the SI Units. Use a full stop to denote decimal values (e.g., 0.007 cm, 0.7 mm).
  • Nauplius uses American English spelling (e.g., color, not colour). Authors who do not have English as their native language are encouraged to use professional proof reading services, or to ask someone highly proficient in English or an English-speaking colleague to review their manuscripts.

After acceptance for publication, a clean final version of the manuscript must be submitted strictly conforming to Nauplius format and style. As you prepare your accepted manuscript to become a published article, please follow these guidelines very carefully. Manuscripts that do not strictly conform to Nauplius format and style will be withheld.

According to the type of publication, the sequence of contents should be:

  • Title: centered, in boldface
  • Full names of Author(s) (left-aligned, one name per line) and their respective ORCID number (
  • Affiliation of author(s)
  • E-mail(s) of all authors (initials of name in boldface, followed by e-mail address)
  • Corresponding author: name and e-mail (on separate lines)
  • Running Head: Abbreviated title (max. 52 characters)
  • Abstract: in English; text should preferably not exceed 250 words.
  • Keywords: usually five, in alphabetical order, separated by comma, and not repeating any terms appearing in title
  • Main text: Introduction, Material and Methods, Results, Discussion (Results and Discussion, in general, as separate sections), Conclusion (if pertinent)
  • Acknowledgements
  • Supplementary material (if available)
  • Additional information and declarations (Contributor roles; Consent for publication; Funding and grant disclosures; Competing interests. If pertinent, also Study association; Study permits; Data availability)
  • References
  • Captions for Tables and Figures

A. Original research articles

Taxonomic papers

In manuscripts dealing with systematics and taxonomy, the organization of the main text can follow a sequence of content more suitable for such papers, usually: Introduction, Material and Methods, Systematics (with any necessary topics, e.g., taxonomic ranks, synonymic list, material examined, diagnosis, description, etymology, type locality, distribution, remarks, etc.) and Discussion (if pertinent).

  • Requirements of taxonomic and nomenclatural procedures need reasonable consistency in the organization of such papers.
  • The establishment of new taxa must follow the requirements of the latest edition of the International Code of Zoological Nomenclature and its Appendices and Amendments.
  • Avoid using the name of new taxa in the title.
  • The International Code of Zoological Nomenclature requires that publication of new taxa in electronic-only journals must be registered in the Official Register of Zoological Nomenclature, with Zoobank as its online version. The Nauplius editorial team will obtain the Zoobank registration number (LSID) of all publications and nomenclatural acts once the manuscript is accepted. The authors should not provide this registration in advance.
  • Telegraphic style is mandatory for descriptions and diagnoses.
  • Accession numbers of publicly available genetic sequence databases (e.g., BOLD, DDBJ, ENA, GenBank) must be included for DNA results such that the raw data can be accessed and compared against the presented data.
  • Tissued specimens should be vouchered and their institutional catalog number provided in association with their respective database accession numbers in the “Material examined” list or in a summary table.

B. Reviews

Nauplius welcomes scientific investigations that reappraise relevant studies on specific topics of Carcinology on the basis of a critical and comprehensive review of the literature. Manuscripts of Review articles should be prepared following the same recommendations as regular articles, but the divisions of the main text may be more flexible at the discretion of the author.

C. Short Communications

Nauplius accepts short notes when they present information that cannot be incorporated into a regular paper. Manuscripts should be prepared following the same recommendations as regular articles; however:

  • The manuscript text should be limited to approximately eight pages written in Times New Roman, size 12pt, and double space formatting, since this will not normally exceed six final printed pages in length and should contain only one figure and/or table.
  • The sequence of contents should be: Title, Full Names of Author(s), affiliation(s) and email(s), Running Head, Abstract, Keywords, Main text (without delimitation of sections), Acknowledgements, Additional information and declarations, References, and Caption for Table and Figure (if any).

Scientific names

  • All generic and binomial names must be in italics, written in full, and followed by the authority the first time they are mentioned in main text (optional in the title and abstract).
  • In the case of the crustacean generic and binomial names, it is mandatory to provide authorship and date of those names. In other animal groups, authorship for generic and binomial names is mandatory, year is optional. If year is given, then the publication regarding the original description of that name must be listed in the “References” section.
  • In taxonomic papers, publications regarding the authorities of the crustacean generic and binomial names must be listed in the “References” section (references for the authorities of suprageneric taxa is optional); in non-taxonomic papers, the listing of the authorities’ references is not required.
  • Authors of species name of any other kingdom need not to be given.
  • When mentioning a species for the first time its binomial name must always be given in full, even if more than one species of the same genus is mentioned in sequence. In subsequent mentions, the contraction of the generic name should be used (e.g., A. spinimanus for Achelous spinimanus). If more than one genus with the same initial is mentioned, use a second letter to distinguish one from the other (e.g., Cl. albidigitus for Clibanarius albidigitus and Ca. obscurus for Calcinus obscurus). Do not abbreviate the genus name at the beginning of paragraphs and sentences, even if it has already been mentioned earlier in the text.
  • When a specific name is cited without its authority and the name of the species is immediately followed by a citation, insert a term to distinguish it from the citation of the authority (e.g.: “see …” or “cf. …”: Macrobrachium carcinus (see Melo, 2003))


  • All publications referred to in the text must be listed alphabetically by the authors’ surname in the “References” section. See the guidelines for further instructions.
  • Authors must make sure that all references cited in the text and eventually in tables are congruent with those listed in the “References” section.
  • In the body of the text cite as follow (depending on the context):
  • One author: Silva (2006) or (Silva, 2006)
  • Two authors: Silva and Santos (2006) or (Silva and Santos, 2006)
  • Three or more authors:  Silva et al. (2006) or (Silva et al., 2006)
  • Citation of more than one reference must be arranged chronologically (not alphabetically) and separated by semi-colons: (Silva, 2005a; 2005b; 2006; Silva and Santos, 2006; Albano, 2008).
  • Do not use “&”, “op. cit.” or “apud”.
  • Use “in press” only when formal acceptance has been granted and a DOI has already been assigned.
  • Citation of theses, dissertations, technical reports, and abstracts presented at meetings is emphatically discouraged. However, if essential, indicate if the document is available online and the URL to access it should be provided, as well as the date of access; a statement of [Unpublished] must be added at the end of the citation.
  • Authors of quoted unpublished material (e.g., manuscript under review, internal report, and certain conference abstracts) should be cited only if strictly necessary. Author (initials and surname) of quoted unpublished material should be inserted in the text and designated as “unpublished data/unpubl. data” or “personal communication/pers. comm.” (e.g., G.A.S. Melo, pers. comm.), but should be omitted from the “References” section.
  • Name of periodicals should be given in full and italic, followed by a comma and the volume number. The issue number (if available) should be in parentheses just after the volume number (no space separating them). Use en-dash (−) for page ranges.
  • Write the Digital Object Identifier – DOI for all works (including older publications, if any) that have a DOI; if an online work has both a DOI and a URL, include only the DOI.
  • Papers published in an online-only journal should show the volume and the e-location (see examples below).
  • In cases of discrepancy with the year of publication of some articles, see further instructions in the guidelines for manuscript preparation with detailed guidelines in addition to the examples below.
  • In the “References” section, the name of authors should be written with the surname followed by a space (no comma) and the initials (no full stop). References with two names must be linked by “and” (not “&”) as well as between the penultimate and the last names of references with three or more authors; use semicolon to separate the other names.
  • For further details please follow the examples below (or check recently published articles):
