Digamasellidae

Dendrolaelaps alongside collembolan, copyright Scott Justis.

Belongs within: Gamasina.

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. 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.
