Santos-Silva, Nearns & Swift, 2016

Prionus geminus is a longhorned beetle in the Prioninae, described in 2016 from material collected in the Great Plains region of North America. It belongs to the subgenus Homaesthesis, a group of grassland-associated Prionus species whose remains poorly documented. The species is part of a whose larvae are subterranean root feeders, though specific associations for P. geminus have not been established.

More Details

Taxonomic history

Described in 2016 by Santos-Silva, Nearns & Swift, making it one of the more recently described in the . The species was recognized from material that had been collected in the Great Plains but previously misidentified or overlooked due to similarity to other Homaesthesis species.

Research challenges

in subgenus Homaesthesis are among the most poorly known Prionus , with many species rarely encountered in collections. The development of prionic acid lures has improved detection of these beetles, though P. geminus specifically has not been documented in lure-based studies published to date.
