Abstract:
Gehypochthonius marianoi n. sp. (Acari: Oribatida), is described from adults and immatures collected in costal sand dunes in Buenos Aires, Argentina. The species is compared with adults and immatures of G. rhadamanthus and G. xarifae respectively, and included in rhadamanthus complex (LEE, 1982). Diagnosis of this complex is discussedKeywords:

Abstract The oribatid mite genus Ceratozetes Berlese is represented in America north of Mexico by 21 previously described species known from forest, grassland, subarctic and arctic soils and litter, and canopy habitats. The closely related genus Ceratozetoides Shaldybina is represented in America north of Mexico only by C. cisalpinus (Berlese). Three new species of Ceratozetes from North America are described: C. biporosus sp. nov. from forest habitats of southeastern North America, C. cyclopea sp. nov. from montane habitats in western North America, and C. pseudomediocris sp. nov. from forest habitats of western North America. A detailed revised diagnosis is given for Ceratozetes , Ceratozetoides , all previously described species of Ceratozetes ( C. angustus (Banks), C. borealis Behan-Pelletier, C. cuspidatus Jacot, C. enodis (Ewing), C. fjellbergi Behan-Pelletier, C. gracilis Michael, C. kutchin Behan-Pelletier, C. longispinus Jacot, C. mediocris (Berlese), C. oresbios Behan-Pelletier, C. pacificus Behan-Pelletier, C. parvulus Sellnick, C. spitsbergensis Thor, C. subaquila (Ewing), C. subinconspicuus (Berlese), C. thienemanni Willmann, C. virginicus (Banks), and C. watertonensis Behan-Pelletier), and Ceratozetoides cisalpinus . Ceratozetes figuratus (Ewing) and C. zeteki (Ewing) are considered junior subjective synonyms of C. enodis (Ewing) syn. nov ., and C. inupiaq Behan-Pelletier is transferred to Mycobatidae as Cyrtozetes inupiaq (Behan-Pelletier) comb. nov . New distribution records are given for Ceratozetoides cisalpinus and Ceratozetes angustus , C. borealis , C. cuspidatus , C. gracilis , C. mediocris , C. longispinus , C. oresbios , C. pacificus , C. parvulus , C. thienemanni , C. virginicus , and C. watertonensis. A diagnostic key is provided to adults of the Ceratozetes and Ceratozetoides species now known for America north of Mexico. An analysis of the systematic relationships of 23 of these species based on adult characters indicates that Ceratozetes , excluding Ceratozetoides , is paraphyletic. The clade that includes Ceratozetoides cisalpinus and 15 species of Ceratozetes includes most species for which immatures are known. One sister clade includes Ceratozetes cyclopea , C. enodis , and C. fjellbergi and another includes C. kutchin , C . parvulus , and C. thienemanni. The decision whether or not these 6 species should be retained in Ceratozetes sensu stricto awaits discovery of their immatures and molecular analysis.

Abstract The oribatid mite family Mycobatidae is represented in America north of Mexico by the eight genera, Cyrtozetes Behan-Pelletier , Ceresella Pavlitshenko , Guatemalozetes Mahunka , Minunthozetes Hull , Mycobates Hull , Pelopsis Hall , Punctoribates Berlese, and Zachvatkinibates Shaldybina. Species occur in forests, grasslands, and arctic soils, in canopy habitats, and in the marine and freshwater littoral zone. Three new mycobatid species from North America are described: Ceresella reevesi sp. nov. from forest habitats of western North America, Cyrtozetes lindoae sp. nov. from canopy habitats of western Canada, and Punctoribates weigmanni sp. nov. from forest litter in eastern North America. The descriptions of Pelopsis bifurcatus (Ewing) and Punctoribates punctum (C.L. Koch) are expanded based on specimens from North America. Punctoribates palustris (Banks) is redescribed based on specimens from throughout North America. Punctoribates armipes (Banks) is considered a junior subjective synonym of P. palustris (Banks). New distribution records are given for Guatemalozetes danos Behan-Pelletier and Ryabinin and Minunthozetes semirufus (Koch). Diagnoses are given for each genus discussed, and keys are provided to the eight genera of Mycobatidae of North America and to species of Cyrtozetes and Punctoribates , genera not recently revised.

A species list of oribatid mites collected from the summit of Yes Tor, Dartmoor, is given, together with notes on their distribution. Yes Tor lies south of latitude 51° in that part of Britain which remained ice free during the Pleistocene. The species found on Yes Tor are compared with the species recorded from the summits of 11 mountains lying north of latitude 53°, which were all ice-covered at the period of maximum glaciation. In the case of Yes Tor and these 11 northern montane sites, three similar faunal elements have been identified arctic-alpine species, European-alpine species and a group of British montane species that are also common in the lowlands. The view is advanced that the similarity of the montane oribatid fauna of Yes Tor with that of the mountains to the north of latitude 53° has resulted from the probable movements of the mites during Quaternary and postglacial times over an area extending from the Arctic Circle to the Mediterranean. It is suggested that these movements, while being largely spontaneous, have also been aided by transportation agents, both physical and biological.
