parsilla

Parsilla is a taxonomic name that has appeared in different biological groups. In zoological nomenclature, Parsilla has been used as a genus name for certain invertebrates; over time, many species originally placed in Parsilla have been moved to other genera as classifications were revised. In botanical literature, Parsilla has occasionally appeared as a genus name in earlier treatments, but current taxonomy often treats Parsilla as a synonym of another genus or regards the name as unavailable, depending on the authority. The exact scope of Parsilla—how many species it included and which organisms are assigned to it—varies with the source and with changes in classification and nomenclatural rules. The etymology is typical of scientific genus names, usually derived from Latin or Greek roots and a diminutive suffix, but it does not imply a single evolutionary lineage. To determine whether Parsilla is currently accepted as a valid genus, researchers should consult up-to-date taxonomic databases (for example, those specializing in zoology and botany) and note the context and authority used, since some databases may treat Parsilla as obsolete, a synonym, or a valid but narrowly defined genus in a particular group.
