Coleopsis is an extinct genus of stem-group beetles. It contains a single species, Coleopsis archaica, and is the only member of the family Coleopsidae. It is known from a single specimen from the Early Permian (Asselian) Meisenheim Formation of western Germany, estimated to be about 297 million years old. It is currently the oldest known beetle.
Taxonomy and systematics
While originally interpreted as a member of the family Tshekardocoleidae, this interpretation has been revised and questioned, with the most recent analyses suggesting that it is best placed in its own family, and may be the sister group to all other beetles.{{cite journal|last1=Schädel|first1=M.|last2=Yavorskaya|first2=M.|last3=Beutel|first3=R.|year=2022|title=The earliest beetle †Coleopsis archaica (Insecta: Coleoptera) – morphological re-evaluation using Reflectance Transformation Imaging (RTI) and phylogenetic assessment|journal=Arthropod Systematics & Phylogeny|volume=80|pages=495-510|doi=10.3897/asp.80.e86582|doi-access=free}} The family name was originally published in 2016 as "Coleopsidae" but a later publication claimed that this spelling was erroneous and proposed the spelling "Coleopseidae";{{cite journal|last=Kirejtshuk|first=A.G.|title=Taxonomic Review of Fossil Coleopterous Families (Insecta, Coleoptera).

29.4. Acceptance of originally formed stem. If after 1999 a new family-group name is based on a generic name which is or ends in a Greek or Latin word or ends in a Greek or Latin suffix, but its derivation does not follow the grammatical procedures of Articles 29.3.1 or 29.3.2, its original spelling must be maintained as the correct original spelling
