sp. n. collected so far were associated with fauna typical of methane seeps (vesicomyid, solemyid, lucinid, and thyasirid bivalves). However, the scarce knowledge of the bathyal SE Pacific malacofauna still keeps us from establishing this species as an obligatory dweller of seep environments or other reducing habitats.
