Studies on freshwater meiofauna are still enigmatic. This field of research is quite Neglected. Publications on this topic are not increasing as much as the others, showing that there is a certain gap when it comes to this area. This paper contains a brief review of what already exists on freshwater meiofauna around the world, focusing on increasing knowledge on this topic and making it a common study field in science, surveying the research in this little known area of meiofauna. For this, the methodology involved a bibliographic survey carried out from Web of Science (WoS) and SCOPUS bibliographic databases. The search was performed by title and keywords, highlighting Meiofauna (or meiobenthos), hyporheic zone (or freshwater). The results showed a number of 28 documents on freshwater meiofauna around the world, mainly concentrated in Germany. Based on this, a discussion was present given these few articles found, highlighting that the lack of researches on freshwater meiofauna community, its ecology, taxonomy and biology, which are consequently poorly known what imposes a barrier on new researchers and researches to emerge in this area and need increase scientific interest at all. It is hoped that this bibliometric review can be used as an alert about this area of meiofauna that is so important but at the same time is neglected, having a very exclusive group of authors and works, being of extreme importance a direction of research that involve freshwater meiofauna, increasing publications worldwide.
