The species belongs to the marronoid spider clade, a large group of predominantly small, brown spiders that has been reclassified through recent molecular phylogenetic studies.

Family placement note

Calymmaria has undergone taxonomic revision. The was formerly placed in Hahniidae, and some sources (including NCBI ) may still list it there. Current classification based on molecular places Calymmaria in Cybaeidae as part of the marronoid clade.

Marronoid clade membership

Calymmaria nana belongs to the marronoid spider clade, a group of approximately 3,400 united by molecular data rather than obvious morphological synapomorphies. This clade includes such as Cybaeidae, Hahniidae, Dictynidae, and others, and exhibits remarkable ecological diversity including social species, intertidal species, and the only fully aquatic spider Argyroneta aquatica.
