Identification

Cymbaeremaeidae can be distinguished from other oribatid by morphological characteristics of the Scapheremaeus, which shows two main morphological categories: with a complete circumdorsal scissure and plicate microsculpture on the circumnotogastral plate with strongly contrasting microsculpture (foveolae, ridges or ) on the centrodorsal plate; and species with little or no contrast in microsculpture between central and lateral regions, typically both regions foveolate or reticulate. instars of Scapheremaeus are characterized by the presence of exuvial scalps on nymphal instars and distinctive gastronotic setae .

Habitat

include soil and litter of various forests, mosses growing on rocks, and arboreal environments. Specific documented habitats include: semi-arid Mallee eucalypt vegetation in South Australia; branches of Lauraceae trees in Vietnam; temporary rock pools with mosses (Grimmia laevigata) on granitic outcrops in Georgia, USA; and arboreal habitats in Florida, USA.

Distribution

Documented from Southern Japan, Eastern China, South Australia, southern Vietnam, Georgia and Florida in the USA, Mexico, and South America. One (Scapheremaeus palustris) has a trans-Atlantic distribution. The Scapheremaeus has been described as having distribution. Distribution records from GBIF include Denmark, Norway, and Sweden.

Life Cycle

Development includes larval and nymphal instars. Nymphal instars are characterized by the presence of exuvial scalps retained from previous instars. Larval instar of Scapheremaeus tonatiuh has gastronotic setae c3, la, lm, lp long and with setiform apex, and h1 very long and subflagellate. Nymphal instars have 12 pairs of gastronotic setae with da, dm, dp absent.
