Killi-Data is a scientific knowledge base, established on latest published evidence.
Nomenclatural and systematic conflicts still resulting are today extremely rare and mainly due to simultaneous independent publications : in case of contemporary-published evidence-based systematic conflicts between authors for a genus or a species, among divergent authors' proposals, selection by Killi-Data will usually be in favor of stability whenever the latest published or not, and, in case of molecular separation of a species previously set as a synonym, revalidation (or reversally synonymization of a previously valid species) is only accepted if a published new diagnosis for impacted taxa is proposed, in both cases fully in line with ICZN principles and rules…
Those deviations from other international databases are very limited since 2009 and reversally other databases have their own rules, however not published and not transparent (a few cases in total listed hereafter compared to over 2200 total available taxa in November 2020, even if a generic decision will have consequences on all specific components) and they are all listed and explained, in full transparency, hereafter in a table that can be sorted out according to columns.
The following list comprises the taxon concerned with the case, the concerned level, either specific or generic, the author and reference of the scientific change, the author(s) and reference(s) of the scientific counter-positions (evidence-based), the date of decision in Killi-Data and the current conclusion-decision, herein.
Obviously the decisions are explained hereafter as [ICZN rule of a mandatory diagnosis for a taxon] or [ICZN unmet criteria of availability] or [contemporary conflicting published evidences, decision not based on latest], or [contemporary conflicting published evidences, decision based on latest published evidence], and this list is evolutive, since cases may disappear once the problem is solved by further new published evidence (i.e., no more present possible conflict) {previous cases today settled : Profundulus vs. Tlaloc, as distinct (a case up to 2019)}.
