AbstractMorphology, distribution, and habitat data are presented for three species of the oribatid mite genus Gymnodampia Jacot occurring in North America. A revised generic diagnosis is given and the type species Gymnodampia setata (Berlese) is redescribed based on topotypic material from Missouri. Immatures of G. setata are described and aspects of their biology are presented. Two new species from North America, G. jacotisp. nov. and G. lindquistisp. nov., are proposed and described on the basis of adults, and a key is given for North American species of Gymnodampia. The ameroid genera Cristamerus Hammer, from Pakistan and China, and Defectamerus Aoki, from Japan, Korea, and China, are considered junior synonyms of Gymnodampia, and G. conformis (Fujikawa) is considered a junior synonym of G. fusca (Fujikawa). Immatures of G. setata are apheredermous, but with a circular line of dehiscence, whereas known immatures of the superfamily Ameroidea are eupheredermous. Nonetheless, without convincing apomorphic traits linking Gymnodampia to any known apheredermous family of Brachypylina, we hypothesize that Gymnodampia has lost the eupheredermy characteristic of Ameroidea, and we place it in the family Ameridae on the basis of adult similarities.

AbstractThe oribatid mite genus Ametroproctus, soil and litter inhabitants in the desert, alpine, and montane regions of western North America, is discussed. Two subgenera are recognized, Ametroproctus s. str. and Coropoculia. Their respective type-species, A. oresbios Higgins and Woolley and C. reticulata Aoki and Fujikawa, are redescribed, and newly discovered immatures of both species are described. Four new species are proposed, A. (Ametroproctus) tuberculosus, A. (A.) aridus, A. (Coropoculia) beringianus, and A. (C.) canningsi. A new generic diagnosis is given, as well as a key to subgenera and species known from North America.

Mite Genus

The genus Pilobatella (Oribatida, Haplozetidae) comprises 10 species, which are distributed in the Palaeotropical region; this includes two new species described herein on the basis of adult specimens sampled from forest leaf litter in Andasibe-Mantadia National Park of eastern Madagascar. Pilobatella mikoi n. sp. is similar to Pilobatella baloghi Mahunka, 2003 in having long interlamellar setae and adanal setae ad1 and ad2, but differs by having monodactylous legs (versus tridactylous) and a bothridial seta that is gradually expanded to a narrow head (versus setiform, without head). Pilobatella kovaci n. sp. is similar to P. mikoi n. sp. in having monodactylous legs, long interlamellar setae and adanal setae ad1 and ad2, but differs by the presence of lineolate notogaster and anogenital region (versus lineolate markings absent), long tutoria (versus tutoria of medium length), rounded trochanters distodorsally (versus pointed) and clearly distanced medial ends of apodemes 2 (versus nearly touching at midline). A revised generic diagnosis and an identification key to known species of Pilobatella are presented.

We describe a new feather mite genus Atelophyllodes gen. n. (Proctophyllodidae: Proctophyllodinae) with two new species from lyrebirds (Passeriformes: Menuridae) in Australia: Atelophyllodes menurae sp. n. (type species) from Menura novaehollandiae Latham, 1802, and A. atyeoi sp. n. from M. alberti Bonaparte, 1850. The unique features of Atelophyllodes that differentiate it from all other described genera of the subfamily Proctophyllodinae involve the structure of opisthosomal lobes in males: lobes are short and wide, with three pairs of extensions bearing bases of setae h2, h3 and f2, and lack terminal lamellae on their posterior margins.

The genus Eutegaeus (Oribatida, Eutegaeidae) comprises 13 species, which are distributed in the Australian, Neotropical and Antarctic regions; of these, two new species are described from litter in the relictual Valdivian forest of Chile. Eutegaeus parapapuaensis sp. nov. (description based on the adult and tritonymph) differs from Eutegaeus papuensis Aoki, 1964 by the absence of translamella, interbothridial tubercles, notogastral setae h3 and epimeral setae 3a. Eutegaeus paralagrecai sp. nov. (description based on the adult and proto-, deuto- and tritonymph) differs from Eutegaeus lagrecai Arcidiacono, 1993 by the presence of lanceolate bothridial setae and long notogastral setae p1, and the absence of striate ornamentation on the notogaster. A revised generic diagnosis and an identification key to known species of Eutegaeus are presented. Nymphs of Eutegaeus and related genera in Eutegaeoidea are compared.

Mite Genus

The oribatid mite genus Eurhynchoribates (Oribatida, Rhynchoribatidae) is recorded in the Philippines for the first time. Two new species are described from litter and soil of secondary forests. Eurhynchoribates samarensis sp. nov. differs from all species of the genus by the presence of 14 pairs of notogastral setae, and is designated as type species of the new subgenus Orinchobates subgen. nov. Eurhynchoribates (Eurhynchoribates) misamisensis sp. nov. is morphologically similar to E. (Eurhynchoribates) obtusus (Mahunka, 1985), but differs by the smaller body size, rostral setae clearly longer than lamellar setae, all barbed, and the presence of two transverse ridges between antero-lateral concavities on the prodorsum. The inclusion of Eurhynchoribates orientalis (Balogh, 1970) in the subgenus Orinchobates is proposed.

The oribatid mite genus Crassoribatula is recorded in the Neotropical region for the first time. One new arboreal species—Crassoribatula biobioensis sp. nov.—is described from twigs of olivillo tree in Chile; it differs from the type species—Crassoribatula maculosa—by the length of exobothridial and notogastral setae. The tritonymphal instar of the new species is described (the first data on juveniles in this genus). The systematic placement of Crassoribatula is discussed, resulting in transfer from Oribatulidae (Oripodoidea) to Maudheimiidae (Ceratozetoidea). A revised generic diagnosis for Crassoribatula is presented.

The oribatid mite family Tegoribatidae has been represented in continental North America by the genera Tegoribates and Tectoribates. Herein, I describe a new genus of Tegoribatidae from North America, Protectoribates, and two new species: Protectoribates occidentalis sp. nov., from forest habitats in western North American, and Tegoribates walteri sp. nov., from forest habitats in California, based on adults and immatures. The descriptions of adults of the type species of Tegoribates, T. subniger Ewing, and other North American species, T. americanus Hammer and T. bryophilus Woolley, are expanded and immatures of T. americanus are described for the first time. Immatures of Protectoribates are apheredermous whereas those of Tegoribates are eupheredermous, though retaining centrodorsal setae. Scutozetes Hammer 1952 is transferred from Tegoribatidae to Ceratozetidae after re-examination of type material. I provide a revised diagnosis for Tegoribates and a key to tegoribatid genera and species for North America. Finally, I provide a revised diagnosis for Tegoribatidae based on world genera.

Mite Genus

A new feather mite genus Armophyllodes gen. n. (Proctophyllodidae: Proctophyllodinae) is established based on two new species, Armophyllodes gracilis sp. n. (type species) and A. robustus sp. n., described from the Olivaceous flatbill, Rhynchocyclus olivaceus (Temminck) (Passeriformes: Tyrannidae), in Panama. The new genus is related to the Nycteridocaulus generic group and clearly differs from other genera in having the strongly sclerotized lateral parts of coxal fields II in both sexes, the epigynum fused with the inner tips of epimerites IIIa in females, and vestigial terminal lamellae in males. The fusion of the epigynum with epimerites is an extremely rare character state in the subfamily Proctophyllodinae; among other known members of this subfamily, it was previously known only in females of Anisophyllodes pipromorphae Atyeo, 1967. In contrast to the subfamily Pterodectinae, in all representatives of which the fusion of the epigynum with epimerites is complete and these sclerites constitute a uniformly sclerotized arch-like structure, in the two species of the genus Armophyllodes and in An. pipromorphae, the traces of fusion between these sclerites are clearly distinct. This gives evidence that the fusion of the epigynum with epimerites in pterodectines and proctophyllodines originated independently.
