Mite Genus

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.

The otocepheid oribatid mite genus Leptotocepheus Balogh, 1961 is recorded in the Australasian region for the first time. The taxonomic status of the genera Leptotocepheus Balogh, 1961 and Longocepheus Balogh & Mahunka,1966 is discussed, resulting in the recognition of Longocepheus as a subgenus (stat. nov.) of Leptotocepheus and the following recombinations: Leptotocepheus (Longocepheus) australis (Balogh & Mahunka, 1966) comb. nov., Leptotocepheus (Longocepheus) globosus (Grobler, 1995) comb. nov., Leptotocepheus (Longocepheus) longus (Balogh, 1961) comb. nov., Leptotocepheus (Longocepheus) youngai (Mahunka, 1984) comb. nov. A new species of Leptotocepheus (Longocepheus) is described from New Zealand, Leptotocepheus (Longocepheus) neozealandicus sp. nov., which differs from other species of the subgenus by the presence of short, slightly developed prodorsal costulae. Revised generic and subgeneric diagnoses, an identification key and distributions for the known taxa of Leptotocepheus are presented.

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.

A new species of microzetid oribatid mites of the genus Kalyptrazetes is described from upper soil and leaf litter in the primary evergreen lowland rainforest of Amazonian Peru. Kalyptrazetes bifurcatus Ermilov sp. nov. differs from other representatives of the genus by the morphology of rostral and centroventral epimeral setae and anterior parts of lamellae, the length of some notogastral, epimeral and genital setae, and the absence of an X-structure in the epimeral region. The main generic traits and an identification key to known species of Kalyptrazetes are provided.

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.

Perxylobates hakkai n. sp. (Oribatida, Haplozetidae) is the second representative of the genus recorded in Taiwan; it is described based on adults from soil under Ricinus communis on a farm of the Agricultural Research and Extension Station in Miaoli District. The new species differs from related Perxylobates coreanus Choi and Aoki, 1993 by the presence of five pairs of genital setae (versus four pairs), four pairs of notogastral porose areas including A3 (versus three pairs, A3 absent), minute epimeral seta 1c (versus comparatively long), roughened epimeral and aggenital setae (versus heavily barbed), and smooth anterior part of prodorsum (versus foveolate). A revised generic diagnosis and an identification key to known species of Perxylobates are provided. The systematic placement of Perxylobates mahunkai Bayoumi, 1980 is discussed, resulting in the following new taxonomic proposal: Protoribates mahunkai (Bayoumi, 1980) n. comb.

A new species of Antarctozetes (Oribatida, Ceratozetoidea) is described from the soil in New Zealand based on adult morphology. Antarctozetes mariehammerae sp. nov. differs from Antarctozetes intermedius (Hammer, 1967) by the short rostral setae, very short stalks of bothridial setae, and bidentate lamellar cusps. A revised generic diagnosis is given, Antarctozetes is maintained in Punctoribatidae, although knowledge of juvenile instars is lacking. The relationship of Antarctozetes, Anellozetes, Africoribates and Kilimabates is discussed. Data on habitat and an identification key to known species of Antarctozetes in New Zealand are provided.
