Explanation of Names
Peiratinae Amyot & Serville 1843; type genus: Peirates (Old World)
medium-sized subfamily with 350 spp. in 33 genera worldwide, 70 spp. in 10 genera in the New World(1); 7 spp. in 3 genera north of Mexico(2)
10-25 mm
Most easily diagnosed by the transverse sulcus being set distinctly behind the middle of the pronotum.
Worldwide; in the New World, restricted to the Nearctic and Neotropica(1); one species transcontinental, others mostly southern
Often found on the ground under rocks or at the base of grasses. They are active hunters, preferring to chase and pounce on their prey. Some species are attracted to lights at night.
Many are probably generalist feeders on various different arthropods but it is thought that some Melanolestes have a preference for melolonthine scarabs and Sirthenea prefer mole crickets.
Members of this subfamily are known for their notoriously painful bites.
Adult females of several species may be brachypterous and can be mistaken for nymphs:
