Wikispecies lists this name as "disputed" which amounts to little more than a procedural issue. Van der Haas found in 2014 "Rivulinidae" was already used for a moth so it has to go. That's not in dispute. The ICZN has not got around to blessing this change yet, which doesn't mean much, the argument is valid and theres no possibility this name change will not happen, it is wrong until it is. Strict adherence to ICZN rules makes this "in dispute" not any flaw in the argument, this in this case adherence to those names implies continuation of a clashing taxa. The killie came later, the moth name isn't going to change.
WikiSpecies explains the issue well.
