• On May 31. 2018, a complete new version of Killi-Data Encyclopedia is publicly online at MENU.
  • On May 17. 2018, Killi-Data Wassup n°2 is sent to members with news covering the period January 16. 2018 to May 16. 2018 : an editorial, a view from the chair, full analyses of selected articles, and collecting trips reports, as a PDF file ; K-D-W is free and can be obtained by anyone interested by killifish research and scientific collecting trips via a simple mail to the editor, asking for K-D-W n°2 and mentioning full name, full postal address (it will not be used, just to avoid fakes) and for aquarists, their killifish association membership and numbers (same reason).
  • On May 16. 2018, the infoweb on Iranian Aphanius research by Germano-Iranian team is updated with new species description of Aphanius hormuzensis by Teimori, Esmaeili, Hamidan & Reichenbacher, 2018 (see INFOWEB 18).
  • On May 16. 2018, the answer by Jean Huber to a question on synonymization of Aphyobranchius in Adiniops, a subgenus of Nothobranchius is published (see FAQ 49).
  • On March 4. 2018, a new page in the members section has been added listing aquarium populations individually and globally by species (note for local, regional, and national associations, the similar and more practical booklet named Killi-Data Pocket is produced for them, now on demand {see also PKD}.
  • On February 9. 2018, major alert: from molecular data, Bragança, Amorim and Costa spin-off all lampeyes from Poeciliids, and upgrade them as 3 distinct families, Pantanodontidae, Procatopodidae, Fluviphylacidae (all systematics since 1981 are reshuffled)… full reading at ZSE ; notes : the pioneering work on the Pantanodon issue is due to Pohl et al. (2015) and the new (smart) study is focusing at higher levels (with only 7 lampeyes in the tree) ; future will tell (with new studies) if Plataplochilus has an ancestral position in African lampeyes contrary to morpho-osteological evidence and future will tell if the scientific community will accept the moves as 3 full distinct families or at less high levels (besides the present move has also consequences on other families, e.g. similarly a recent study proposed that Aphaniini be raised to family level, and the present new study recognizes only 1 family in Aplocheilidae, instead of 3 as Aplocheilidae, Nothobranchiidae, "Rivulidae"… not the end of the story ! {see also FGN footnote 20}.
  • On February 5. 2018, a new upload of the database is finalized (see statistics above and some more, e.g., number of annual species or not, number of species according to water characteristics).
  • On January 31. 2018, a new service to members named Killi-Data Wassup is announced with news covering the period December 1. 2017 to January 15. 2018 : an editorial, a view from the chair, full analyses of selected articles, and collecting trips reports, as a PDF file ; K-D-W is free and can be obtained by anyone interested by killifish research and scientific collecting trips via a simple mail to the editor, asking for K-D-W n°1 and mentioning full name, full postal address (it will not be used, just to avoid fakes) and for aquarists killifish association membership and numbers (same reason).
  • On January 3. 2018, the new year starts full speed with 3 new 'Aphyosemion' species described from the upper Louessé River in the Massif du Chaillu, in (former French) Congo, namely 'Aphyosemion' cyanoflavum, 'Aphyosemion' mandoroense, and 'Aphyosemion' cryptum (the genus 'Aphyosemion' is used between kommas because the authors believe their species are positioned in an uncertain genus). Those 3 new species are either related to ogoense group or to coeleste group (also with commas... more to come!).
  • On December 24. 2017, the fourth issue, second year, (30 pages) of Killi-Data News has been published and sent to all active members as a PDF. [it includes the analysis of the description of Pseudorestias, the important new paper by the Tatarenkov team on Kryptolebias marmoratus with surprising (but yet not ultimate) results, the various descriptions of new species, a major molecular paper on Crenichthys (with more mysteries than ever), a new article with a lot of implications on aquarium breeding of annuals (on Austrolebias nigrofasciatus), the first ecological on Rivulus rossoi by a new research Brasilian team, etc., etc. [Jean Huber].
  • On November 21. 2017, the answer by Jean Huber to a question on invalidity of subspecies and their detriment to species identification, conservation, and understanding based on a Crenichthys case is published (see FAQ 48).
  • Previous alerts in this page are to be read at INDEX-ARCHIVES.
  • The "guest" or "public" section is fully open and anonymous (no e-mail needed to enter) and it is fully updated with automatic programmes and a list of alerts (brand new latest publications) plus their inventories at FLASH-ARCHIVES
  • The "members" section is restricted to members after free REGISTRATION, with 9 ethical commitments.
  • The "members" section mainly contains the knowledge base and all killiflash since at least 1961 (all major publications on killifish with reference, abstract and/or short analysis for each) : to freely check the contents of the database, please read the SAMPLE page, or if you intend to write an article, ask for a GRATUITY page of a given name of killifish.
  • The "guest" section holds a lot of advertising (please readily click on links if interested) : this is aimed to cover the costs of web-hosting each year so that personal costs to the editor (Dr Jean H. Huber) are limited.
  • This is not any more, at the generic level, a mirror of current research in case of published conflicts (it became too unstable since 2009) but an objective and conservative analysis of current evidence-based knowledge by the editor (hopefully a scientific advisory board in the future !), in order to avoid too numerous name changes without added value and without stability sake ; but this only concerns the generic level, while the species level is, as usual, automatically derived from latest published evidence, at least with a re-diagnosis in case of proposed revalidation (beware, that strategy is different from listing various published results and/or published opinions to compare them without deciding) ; in any case, Killi-Data complies with principles, recommendations and rules of ICZN (International Commission of Zoological Nomenclature), notably in terms of stability and universality.

Mission statement

legend  Killi-Data aims to present all available information on Killies or oviparous Cyprinodontiformes fishes.
Killi-Data compiles state of the art knowledge, wherever it sources from, scientist or aquarist.
Killi-Data is evidence based, not opinion based. If conflicting results arise from distinct phylogenetic methods, then a compromise is selected that purports the maximum of results, ending up in a splitting way if stability is not threatened.
Killi-Data is a non-profit venture that redistributes all financial benefits, the major part being attributed to young scientists or collectors to support research on oviparous Cyprinodontiformes fishes or Killies.
Killi-Data strongly encourages cooperation between ichthyologists, either professional or amateur, and aquarists to build a cooperative community of interest and knowledge.
