Tetraloniella is a traditional genus of bees (family Apidae ), in German longhorn bees . According to recent phylogenetic studies, however, this genus is assigned to Eucera , it is considered a synonym for Tetralonia . However, it is (still) viewed by various authors as a separate genre. At least among the native species, the species of Tetraloniella differfrom most other species of the genus Eucera in that they have three cubital cells ( Eucera s. Str. Two cubital cells).

Over 120 species of Tetraloniella have been described worldwide, many of them in the New World.

After the revision by Achik Dorchin and colleagues on a genetic and morphological basis, the genus Tetraloniella , as traditionally understood (for example in Michener's standard work Bees of the World , which, however, had already suspected paraphyly), is not a monophyletic unit. The Palearctic species of the earlier genus, mixed with species of the earlier genus Tetralonia , form a paraphyletic cluster basal to most of the other species of the Eucerini tribe, including Tetralonia malvae, the type species of this genus. Xenoglossa , Peponapis and Cemolobus were monophyletic themselves, but nested in a paraphyletic tetralonia . The key morphological feature, the number of cubital cells, turned out to be highly homoplastic and unsuitable for generic diagnosis . The authors were able to identify a clade from Palearctic species of the former genera Tetralonia , Tetraloniella and Eucera , which they proposed as a newly delimited subgenus Tetralonia of the genus Eucera . Other Tetraloniella species belonged to different clades. According to the results, this generic name must therefore be abandoned.
