'''''Repinaella''''' is an extinct genus from a well-known class of fossil marine arthropods, the trilobites. It lived during the late Atdabanian stage.
== Distribution == * ''Repinaella siberica'' has been found in the Lower Cambrian of Siberia (Pestrotsvet Formation, Lena River).<ref name="Hollingsworth">{{cite journal|last=Hollingsworth|first=J.S.|year=2005|title=The earliest occurrence of trilobites and brachiopods in the Cambrian of Laurentia|journal=Palaeogeography, Palaeoclimatology, Palaeoecology|volume=220|issue=1–2|pages=153–165|url=http://ysgeo.yonsei.ac.kr/abstractII/E0422001009.html|doi=10.1016/j.palaeo.2004.08.008|bibcode=2005PPP...220..153S|url-status=dead|archive-url=https://web.archive.org/web/20140606221919/http://ysgeo.yonsei.ac.kr/abstractII/E0422001009.html|archive-date=2014-06-06|url-access=subscription}}</ref> * cf. ''Repinaella sp.'', the first trilobite to appear in Laurentia, has been reported from the Lower Cambrian of Nevada (Northern Clayton Ridge; Andrew Mountain Member of the Montezuma Range, Campito Formation).

== Taxonomy == Within the "Fallotaspidoidea" superfamily ''Repinaella siberia'' is closest to the common ancestor with the other Olenellina, particularly ''Pseudojudomia egregia'', and the common characters of these two species were probably shared with the common ancestor of all trilobites.<ref name="Lieberman 2002">{{cite book|last= Lieberman|first= B.S.|title= Phylogenetic analysis of some basal early Cambrian Trilobites, the biogeographic origins of the Eutrilobites, and the timing of the Cambrian radiation|year= 2002|journal= Journal of Paleontology|volume= 76|number= 4|pages= 692–708|url= https://books.google.com/books?id=KykRuQwrVuUC&pg=PA153 |doi=10.1666/0022-3360(2002)076<0692:paosbe>2.0.co;2|isbn= 9780444520654}}</ref>
