Plusiocampa Silvestri, 1912
Peck (1973) reported Plusiocampa sp. from Craig Ice Cave and Frozen River Cave (Siskiyou County); these may instead be Haplocampa “Lava Beds N.M.” We know of no specimens of Plusiocampa from California; Allen (2002) reports this genus only from Mexico; these records should be confirmed before this genus is confidently added to the California checklist.
