The Digamasellidae are a widespread group of mostly predatory mites though the genus Digamasellus is considered fungivorous. Members of the genera Dendroseius and Dendrolaelaps possess two pairs of light-refractive structures between the setae z5 on the podonotum. Dendroseius have six evenly wide rows of denticles in the hypognathal groove whereas Dendrolaelaps have five rows of hypognathal denticles with the proximal row wider than the others. Digamasellus species lack setae z3 on the podonotum and have an enlarged anal opening (Evans & Till 1979).

Characters (from Lindquist et al. 2009): Dorsal shield of adults divided; palpi five-segmented, palptarsal apotele two-tined; legs IV usually with seven setae on genu (1 2/1, 2/0 1) and seven on tibia (1 1/1, 2/1 1); anterior portion of female sternal shield and male sternitigenital shield weakly defined; male with sternal setae st5 on separate platelets; female with separate epigynal shield.
