Zachycinae

Zachycinae is a subfamily of beetles within the family Carabidae, commonly known as ground beetles. This subfamily is characterized by its distinctive features, including a unique structure of the male genitalia and a specific pattern of setae on the elytra. Zachycinae is found primarily in the tropical regions of the world, with a significant number of species occurring in South and Southeast Asia.

The subfamily Zachycinae was first described by the entomologist Maximilien Chaudoir in 1876. It is named after the genus Zachys, which was established by Chaudoir himself. The genus Zachys is one of the most species-rich genera within the subfamily, with over 100 described species.

Species within Zachycinae are typically small to medium-sized, with a body length ranging from 5 to 15 millimeters. They are often found in leaf litter, under rocks, and in other moist habitats. Zachycinae species are known for their predatory behavior, feeding on a variety of small invertebrates.

Despite their ecological importance, Zachycinae species are not well-studied, and much remains unknown about their biology and ecology. Further research is needed to better understand the diversity and distribution of this subfamily, as well as their role in ecosystems.
