Sejus
Sejus is a genus of sejine mites in the family Sejidae, superfamily Sejoidea. The genus contains approximately 17 described species. Members of this genus exhibit a mixture of primitive and derived characters typical of the Sejoidea, including hypertrichy, a distinctive female sterno-genital region, and a phoretic deutonymph stage. Sejus species are generally distributed in warmer regions globally, though at least one species (S. americanus) extends into boreal zones.
