Nanoclepta currently comprises a single species,
Nanoclepta minutus Ncl‐1, an anaerobic hyperthermophile (optimal growth observed from 80 to 85°C) cultivated from a New Zealand hot spring. Cells are ultra‐small cocci (∼200 nm) with archaeal flagella and are cultivated in near‐neutral pH conditions (pH ∼6.0). Like several other

. N. minutus, the relationship is not required for the host,
, which can survive as a free‐living organism.
. N. minutus has a highly reduced genome (∼0.58 Mb) with minimal biosynthetic potential and no detected ATP synthase genes, and
. Nanoclepta cells likely rely on their host for many metabolic precursors.
