Megathous nigerrimus is a species of click beetles in the family Elateridae. [1]
This species can be found in France, Italy and Switzerland. It is the most widespread species within the genus Megathous. [2] It is mainly known from the French and Italian Maritime Alps, Alpes-de-Haute-Provence and Piedmont. [3]
Megathous nigerrimus can reach a body length of about 20 mm (0.79 in). These click beetles are entirely black, moderately shiny, including antennae and legs. They are covered with fine and not very thick pubescence. Antennae are serrated from third article. Frons is arcuate anteriorly with margin simple on level with clypeus at middle. [4]
The larvae develop as predators in decayed trunks and stumps of different tree species. Adults have crepuscular habits. [4]
Elateridae or click beetles are a family of beetles. Other names include elaters, snapping beetles, spring beetles or skipjacks. This family was defined by William Elford Leach (1790–1836) in 1815. They are a cosmopolitan beetle family characterized by the unusual click mechanism they possess. There are a few other families of Elateroidea in which a few members have the same mechanism, but most elaterid subfamilies can click. A spine on the prosternum can be snapped into a corresponding notch on the mesosternum, producing a violent "click" that can bounce the beetle into the air. Clicking is mainly used to avoid predation, although it is also useful when the beetle is on its back and needs to right itself. There are about 9300 known species worldwide, and 965 valid species in North America.
The Elateroidea are a large superfamily of beetles. It contains the familiar click beetles, fireflies, and soldier beetles and their relatives. It consists of about 25,000 species.
Camillo Rondani was an Italian entomologist noted for his studies of Diptera.
The fauna of Italy comprises all the animal species inhabiting the territory of the Italian Republic and its surrounding waters. Italy has probably the highest level of faunal biodiversity in Europe, with over 57,000 species recorded, representing more than a third of all European fauna. This is due to various factors. The Italian peninsula is in the centre of the Mediterranean Sea, forming a corridor between central Europe and North Africa, and it has 8,000 km (5,000 mi) of coastline. Italy also receives species from the Balkans, Eurasia, and the Middle East. Italy's varied geological structure, including the Alps and the Apennines, Central Italian woodlands, and Southern Italian Garigue and Maquis shrubland, also contribute to high climate and habitat diversity.
Megapenthes lugens is a species of primarily European click beetle. The adult is black, narrow and 7–10 mm (0.28–0.39 in) long. The larvae feed on weevil larvae in the decaying trunks of beech and elm. In July 2010, the common name "queen's executioner beetle" was proposed following a competition.
