Trechinae
Trechinae is a subfamily of ground beetles (Carabidae) containing over 6,700 described species across more than 430 genera and 6 tribes. The group exhibits remarkable diversity in habitat preferences, ranging from surface-dwelling species in alpine páramos and saline coastal environments to highly specialized troglobitic (obligate cave-dwelling) forms with extreme morphological adaptations including eyelessness and depigmentation. Notable tribes include Trechini, which contains the most morphologically modified cave-adapted species, and Pogonini, which are primarily associated with humid and saline environments.
