Calathus is a genus of ground beetle native to the Palearctic (including Europe, the Near East, and North Africa). There are at least 190 described species in Calathus. [1] [2] [3] [4]

The genus includes species that present different forms in relation to wing length. In some species, this phenotype is determined by a single locus gene, in which short wings are dominant. Other species, however, have lost this polymorphism, expressing either the short-winged morph or the long-winged morph. One species, Calanthus melanocephalus, still presents both forms, but they're determined by the environment, specifically temperature and food conditions, instead of depending on the genotype of the individual, in what's called polyphenism.
