Calopterini

Members of Calopterini can be distinguished from other Lycidae by the combination of eight pronotal stemmata, subserrate antennae with antennomere III longer than II but much shorter than IV, and strongly hooked mandibles. Within the tribe, the genus Lycinella is characterized by these features and is restricted to the Neotropical region.

Specific habitat preferences are poorly documented. Specimens of Lycinella have been collected exclusively in Malaise traps, suggesting association with forest canopy or mid-story vegetation. One species (L. adamantis) was collected at 2350 m elevation, indicating montane forest occurrence.

Neotropical region: documented from Central America including Costa Rica, Panama, and Guatemala. The tribe's range corresponds to that of its constituent genus Lycinella.

Females are unknown and presumed neotenic based on placement within the subtribe Acroleptina, where neoteny has been suspected in related taxa. This represents an inferred rather than directly observed life history trait.

Males are flight-active. Virtually all known specimens have been captured in Malaise traps, indicating aerial activity patterns consistent with canopy or subcanopy flight.

• other Lycinae tribesCalopterini differs in the specific antennal formula (antennomere III longer than II but much shorter than IV) and the presence of eight pronotal stemmata, whereas related tribes may have different stemmatal counts or antennal proportions.
