Solicitrii

Solicitrii is a fictional genus of aquatic invertebrates created for instructional examples in biology and taxonomy. It is not a real taxon and has no standing in formal nomenclature.

Etymology: The name combines Latin solici- from sollicitare “to solicit,” with the common genus suffix -rii, chosen to resemble standard zoological naming conventions. The label is intended to illustrate how new genera are formed within a teaching context and does not reflect any actual lineage.

Taxonomy and description: In the educational framework, Solicitrii is placed within a provisional family Solicitriidae and a notional order Solicitriiformes, chosen to resemble real hierarchies. This arrangement is for pedagogical demonstration only and does not correspond to any legitimate clade.

Morphology and ecology: Members are depicted as small, 0.5–2 mm, translucent organisms with a soft body and a shallow carapace-like mantle. They are described as detritivores feeding on microalgae and organic particles, living in freshwater ponds and slow streams. Reproduction is described as sexual with external fertilization, producing free-swimming larvae, again for illustrative purposes.

Species commonly cited in teaching materials include Solicitrii lumina and Solicitrii aqua, each illustrated with slightly different shapes or colors to aid identification. These distinctions are fictional and used to demonstrate how species concepts and descriptive keys function in practice.

Educational use and reception: The term is widely used in introductory textbooks and online tutorials to illustrate the basics of binomial nomenclature, taxonomy, and comparative anatomy. Critics note that fictional taxa should be clearly labeled to prevent confusion, and educators typically emphasize its role as a teaching aid rather than a real biological entity.
