Oedemera femoral is a beetle from the family of oedemeridae (Oedemeridae). The yellow-brown beetle has dark spots in various places. It is unusually elongated. It becomes thirteen to eighteen millimeters long and is very rare in its entire range.
Comment on the name
The species is listed in the standard work Freude-Harde-Lohse Die Käfer Mitteleuropas under the name Oncomera femorata ( Fabricius , 1792). However, the genus Oncomera is classified as a subgenus of Oedemera in the Fauna Europaea . The beetle described in Freude-Harde-Lohse (and here) is a subspecies femoralis femoralis.
The species Oedemera femorata ( Scopoli , 1793) is a species different from Oedemera femoralis .
Description of the beetle
The beetles are 13-18 mm long. As with all horned beetles, the front hip cavities are open at the back, with Oedemera the front and middle hips are cone-shaped and touch each other. The front rails have two end pins. In the male, the hind legs are thick and the hind legs and rear rails are curved inward. The hind tarsi are four-limbed, all others five-limbed (tarsi formula 5-5-4). In all tarsi the limb in front of the claw limb is widened like a lobe on both sides and has a margin at the top. There is a dark spot in the middle of the hind legs and at the end of the fore legs.
The pronotum is rounded at the sides and unedged, its sides are simply bent down. It is narrow and somewhat narrowed towards the back. It is edged at the base, the edge is bent up. It is sparsely and more coarsely punctured than the head. It is darker brown to black on the sides.
The head is not suddenly constricted behind the temples, stretched forward, the upper jaws are clearly visible from above. The head is finely dotted and has a dark spot on the forehead. The eyes are on the side of the head. They are large and protruding, slightly outlined at the front when the antennae are turned in. The forehead is as wide between the eyes as it is between the antennae turns. The antennae are eleven-limbed, thread-shaped and longer than half the body's length. The jaw probes are four-part, but the first part is very small. The end link is cylindrical, hardly thickened on the outside and truncated at an angle (Fig. 1).
The long, soft elytra are roughly punctured and have rounded shoulders that protrude well beyond the base of the pronotum. They have three keel-like raised veins. The first (inner) vein does not run straight back, but bifurcates irregularly. This distinguishes the species from the similar Nacerdes carniolica . At the end, the wing covers are individually rounded and slightly gape apart at the seam.
