Ceuthophilinae is a of Rhaphidophoridae comprising North American cave crickets. Members exhibit morphological adaptations to subterranean life including reduced and depigmentation. They serve as for parasitic larval mites in the group Parasitengona. The subfamily includes such as Ceuthophilus and Hadenoecus.

Identification
Distinguished from other Rhaphidophoridae by Nearctic distribution and association with cave . Differs from Dolichopodainae (sand-treader crickets) by habitat preference and leg proportions. Separated from Asian and Australasian cave cricket lineages by geographic range. Genitalia and tarsal segmentation provide definitive characters for -level identification.

Habitat
Subterranean environments including caves, mines, and deep rock crevices. Also recorded in surface-adjacent dark microhabitats such as cellars, animal burrows, and spaces beneath stones or rotting wood where light penetration is minimal.
Distribution
North America. Range extends across continental United States and into Canada and Mexico, with distributions varying by .
Host Associations
- larval Parasitengona (Acari: Prostigmata) - Larval mites parasitize cave crickets; specific include Ceuthothrombium cavaticum (Trombidiidae)
Ecological Role
Serve as for parasitic mites, linking subterranean . As or scavengers (inferred from ), contribute to nutrient cycling in cave .
Human Relevance
Occasionally encountered in cellars and basements, where moisture and darkness mimic cave conditions. Not known to cause structural damage or pose health risks.

Etymology and naming
The name derives from the type Ceuthophilus, from Greek 'keuthos' (hidden, secret) and 'philos' (loving), referring to their concealed cave-dwelling habit.
