Athous cribratus
Athous cribratus is a click beetle in the Elateridae. Like other members of the Athous, it possesses the characteristic clicking mechanism that allows the to right itself when flipped. The is documented from limited observations, with its specific ecological preferences remaining poorly characterized.

Identification
Distinguished from other Athous by the presence of dense, sieve-like (cribrate) punctation on the pronotum and , as suggested by the specific epithet 'cribratus'. The Athous is characterized by elongated, parallel-sided bodies with and a prosternal process that fits into a mesosternal cavity to enable the clicking mechanism. Accurate identification to species level requires examination of punctation patterns and male genitalia.
Distribution
Documented occurrence in Europe; specific range boundaries are not well established due to limited observation records.
Behavior
Possesses the elaterid clicking mechanism: when disturbed or overturned, the arches its body and rapidly snaps the prosternal spine against the mesosternal groove, producing an audible click and propelling the beetle into the air to right itself.
Similar Taxa
- Athous haemorrhoidalisSimilar size and general body form, but distinguished by lacking the dense cribrate punctation characteristic of A. cribratus; A. haemorrhoidalis has a more uniformly punctate pronotum and often shows reddish coloration at the elytral apices.
- Athous subfuscusOverlaps in distribution and ; A. subfuscus has finer, more scattered punctation and a darker, more uniform coloration without the pronounced sieve-like sculpturing of A. cribratus.

Etymology
The specific epithet 'cribratus' derives from Latin 'cribrum' (sieve), referring to the densely punctate, sieve-like surface sculpturing characteristic of this .
Taxonomic Note
The Athous is -rich and taxonomically challenging, with many species distinguished by subtle differences in punctation, antennal proportions, and male genitalia. A. cribratus is among the less frequently documented species in the genus.
