Summary

Gabrius is a genus of beetles in the family Staphylinidae, with a total of 42 species (including 6 adventive) in the area and over 300 species worldwide. It is characterized by specific anatomical features and a cosmopolitan distribution.

Physical Characteristics

Within the genus Gabrius, the first four segments of the protarsus have a ventral face bearing only regular, unmodified marginal setae, which are simple and not dilated. The last segment of the labial palpus is slender and distinctly narrower than the preceding segment.

Identification Tips

Look for the specific arrangement of setae on the protarsus and the shape of the labial palpus. Also note the position of the lateral puncture of the pronotum, which bears a long seta close to the superior line of the prontal hypomeron.

Habitat

Gabrius species can be found in forest leaf litter, squirrel middens, on dead trees, and in wet debris or moss near water. Adventive species often inhabit compost and other synanthropic habitats.

Distribution

Most species are found in Eurasia and Africa; some are present in the Neotropics. The genus is widespread within our area but is more diverse in the western regions.
