Anthobium florale tenenbaumi Bernhauer, 1931 (p. 232)
Locus typicus: "Umgebung von Pieniny Pustelnia (Sw. Kingi) in Polen" (= near Pieninski castle, southern Poland)
Eusphalerum tenenbaumi (Bernhauer, 1931)
Anthobium florale auct. nec Paykull, 1789 (misidentification)
Eusphalerum florale auct. nec Paykull, 1789 (misidentification)

In publications before the year 2000, this species is usually called "Eusphalerum florale Panzer, 1793". However, this is a nomenclatural error. Panzer (1793) did not describe a new species, but clearly attributed his use of the name "Staphylinvs [sic!] floralis" to earlier treatments by Fabricius (1792) and Paykull (1789). Paykull is the original author of the name, and Fabricius was only copying the treatment by Paykull. Paykull does not give an illustration of his Staphylinus floralis, but from the description it is very clear that the species cannot belong to Eusphalerum: Paykull describes the "thorax" as "weak" (thus indicating a narrow prothoracic shield) and the antennae are described as "broadened on the outside" (thus indicating an antennal club). Panzer refers to the treatments by Fabricius and Paykull, but in addition provides an illustration. Unfortunately, the insect figured by Panzer does not at all agree with the original concept by Paykull. In fact, the insect figured by Panzer might indeed belong to Eusphalerum or a related genus. Numerous authors have therefore accepted the error by Panzer as the description of a new species "Staphylinus floralis" and have identified it with the present species, therefore using the name "Eusphalerum florale". At the same time, these authors have accepted Paykull´s "Staphylinvs floralis" as being the original description of an entirely different species that is now called Phyllodrepa floralis. Of course, this action is nomenclaturally incorrect for two reasons: first, the use of the name by Panzer is a simple misidentification, not the original description of a new taxon. Second, even if we accept the treatment by Panzer as an original description, then Panzer´s name is a junior primary homonym of Paykull´s name, and is therefore invalid. As a consequence, the present taxon has been without a nomenclaturally valid name until Bernhauer (1931) described a "variety Tenenbaumi". This description consitutes the first available name for the present species.
