– Hypogastrura (Ceratophysella) brevis Christiansen & Bellinger, 1980: 155

Remarks: As stated by Fjellberg (1985, p. 43), these records “belong to a complex with several Nearctic forms/species, both described and undescribed, which are all poorly known and distinguished by rather small and dubious characters”. Babenko & Fjellberg (2006) speculate that some of these forms, northern ones in particular, may be conspecific with C. czelnokovi, a widespread and highly variable East Palaearctic species (see also Babenko et al. 2017).
General distribution: Nearctic.
