Contribution to knowledge of the oribatid mite family Epactozetidae (Acari, Oribatida), with description of a new species of Truncozetes from Guatemala.

The family Epactozetidae (Oribatida) is recorded in Guatemala for the first time. A new epactozetid species of the genus Truncozetes – T. izabalensissp. nov. – is described, based on adults collected from the Guatemalan rainforest litter. It is characterized by: number of leg claws (leg I monodactylous, legs II–IV tridactylous); medium-sized lamellar seta inserted in anterolateral part of the lamella; straight translamella; the location of notogastral setae lm and lp (shifted in dorsolateral part from dorsocentral part of notogaster); and the absence of epimeral longitudinal stria. Main family and generic traits are provided. The identification key, distribution and habitat to the known representatives of Epactozetidae are presented. [ABSTRACT FROM AUTHOR]
