Megacephalini
Big-headed Tiger Beetles
Megacephalini is a tribe of tiger beetles (family Cicindelidae) characterized by notably enlarged heads relative to body size. The tribe includes approximately seven described species across at least two genera, with Megacephala and Tetracha being the most prominent. Members are distributed across the Americas, with some species showing strong habitat specialization for saline or alkaline environments. The taxonomy of this group has undergone recent revision, with former subgenera of Tetracha elevated to generic status.
