What is "lampyrini"

The Lampyrini are a tribe of fireflies in the large subfamily Lampyrinae. The lineage formerly separated as Pleotomini seems to be a specialized offshoot of the Lampyrini not too distant from the type genus Lampyris and is therefore included here. This tribe occurs throughout the Holarctic and contains the typical "glowing" or "continuous-light" fireflies from that region. Some otherwise very advanced Lampyrini, like species in Paraphausis and Pyrocoelia, have degenerated light-producing organs again and communicate primarily or even exclusively with pheromones like the ancestors of the fireflies did.
