47 spp. in 2 genera in our area, 49 spp. in 3 genera total(1)
eyeless and wingless beetles; antennomeres 7, 9 and 10 each bearing several teeth in Catopocerus (east of the Mississippi River), without teeth in Pinodytes (west of the Mississippi River)(1)
holarctic (one small genus in ne. Asia); widespread in the US, with 3 spp. ranging into BC & AK (one genus each east and west of the Mississippi River); all spp. but two have allopatric ranges(1)
deep litter and soil, usually in cool temperate and moist forests; occasionally taken in caves, under rocks or in pitfall traps(1)
adults active during various seasons, often in midsummer, but some spp. are known mostly from late fall and winter months when cool and moist conditions seem to bring them up into the more surficial layers of soil/litter(1)
subterranean yeasts or fungi(1)
