Triangulus is a genus of parasitic barnacles in the family Triangulidae, the sole genus of the family. There are at least four described species in Triangulus.
Taxonomy
The genus Triangulus was established by George Smith in 1906 for rhizocephalan barnacles. Molecular phylogenetic research published in 2020 found that Triangulus munidae represents a lineage distinct from the family Lernaeodiscidae, in which the genus had traditionally been placed. Høeg et al. therefore established the family Triangulidae for Triangulus, with T. munidae as its type species.
The same study found that Triangulus galatheae was not closely related to T. munidae and transferred it to the new genus Paratriangulus. The authors retained T. bilobatus, T. cornutus and T. papilio in Triangulus, while noting that their placement required confirmation by future molecular analyses.
Species These species belong to the genus Triangulus: Triangulus bilobatus (Boschma, 1925) Triangulus cornutus (Boschma, 1935) Triangulus munidae Smith, 1906 Triangulus papilio (Kossmann, 1872)
