Endophloeus markovichianus (incorrectly often marcovichianus ) is a beetle belonging tothe Zopheridae family and the Colydiinae subfamily, traditionally considered to be a separate family Colydiidae. The genus Endophloeus is represented worldwide with three species , all of which can also be found in Europe. Only Endophloeus markovichianus is knownfrom Central Europe, the other two species occur in Ukraine and in the Middle East.
Notes on the name
The species is first described in a travelogue by Piller and Mitterpacher in 1783 under the name Sylpha Markovichiana and named after Stephan Markovich , who was a guest of the authors in Cernik . The generic name Endoploeus (from ancient Greek ένδον (éndon), inside, and φλοιός (phloiós), bark.) Was given by Déjean in 1834 and refers to the habitat in which the beetles can be found.
Physique of the beetle
The shape of the flat and oval beetle is reminiscent of the genus Silpha , but differs, among other things, in the number of tarsal limbs and the reinforcement of the exoskeleton. The body length varies between four and seven millimeters. The color is very indeterminate with various shades of brown and without a clear drawing.
The broad head is drawn back into the pronotum up to the large eyes that stand to one side . The eleven-part antennae are thin, the ninth part thickens to form the final two-part club. The antennae are pivoted under the head, the antennae are short, flat and inclined inwards. The jaw probe is four-part, the lip probe is three-part, its end part is egg-shaped with a truncated tip.
The pronotum is significantly wider than it is long. Its sides are lightened, broadly flattened and set with serrated teeth. On the upper side, symmetrical to the center, there are six jagged, elongated humps. They are crowned by tufts of bristles and delimit a longitudinal groove that is widened circularly in front of the center.
The elytra are narrowly flattened at the edge and finer notched than the pronotum. On each serrated tooth there is a flattened scale bristle that protrudes to the side (Fig. 5). At the top, the wing covers are also covered with rib-like humps that carry tufts of bristles. A stripe on the base of the wing cover as well as the edge and the end of the wing cover are encrusted whitish.
The underside of the body (Fig. 4) is flat. The front, middle and rear hips are clearly separated from each other. The tarsi are all four-part. The first three limbs are about equally short and softly haired at the bottom. The rails are without end spikes.
Way of life
The beetles can be found in deciduous and mixed forests under fungal, dead bark of numerous deciduous and coniferous trees or in rotten, fungal wood. They can also be found under lichens and moss.
distribution
The species is found in large parts of Europe, North Africa and the Middle East, but the distribution is very patchy. It is missing on the large European islands, as well as in large parts of Northern Europe, the Benelux countries, Albania, the Czech Republic and some small states.
