Mite Genus

Neopilizetes is a genus of the oribatid mite family Galumnidae that was first characterized by having well-developed setae, a dorsosejugal suture, and raised striae on the prodorsum and notogaster. It was proposed to accommodate Pilizetes neotropicus Balogh & Mahunka 1978 from Brazil—the only supposed Pilizetes species known outside the Ethiopian Region—and it has remained monotypic. We found adults of N. neotropicus and four related species in soil–litter interface samples of a single cacao plantation in Ilhéus, Bahia, Brazil. Herein we: redescribe N. neotropicus; describe Neopilizetes thoracicus n. sp., Neopilizetes tigris n. sp., Neopilizetes triumnasus n. sp. and Neopilizetes unumnasus n. sp., and use this information to develop a new concept and expanded diagnosis of Neopilizetes. A key to the five species is provided, and we offer reasons for rejecting the classification of Neopilizetes as a subgenus of Pilizetes.

The oribatid mite genus Gephyrazetes (Oribatida, Mochlozetidae) is recorded for the first time in the Ethiopian region; one new species is described from soil and litter of Korup National Park in Cameroon. Gephyrazetes umukusumae sp. nov. differs from G. fasciatus Hirauchi, 1999 by the larger body size, truncate lamellar cusps, setiform bothridial setae, very small notogastral porose areas, paraanal position of adanal lyrifissures, presence of four pairs of genital setae and tuberculate lateral parts of prodorsum, and absence of dorsosejugal and sublamellar porose areas. Revised generic diagnosis and the data on distribution and ecology of Gephyrazetes species are presented.

Three new species of the oribatid mite family Oppiidae are described from soil and coniferous litter of Hogsback State Forest, Eastern Cape Province, South Africa. Brachioppia bituberculata sp. nov. differs from its related species, Brachioppia excrescens and B. louwi, by the localization of cilia on the bothridial head and length and placement of dorsal notogastral setae. Kokoppia macrotuberculata sp. nov. differs from its related species, Kokoppia longisetosa, by the body length, the length of notogastral setae, the localization of notogastral setae la and lm, and the presence of interbothridial macrotubercle. Pletzenoppia ethiopica sp. nov. differs from its related species, Pletzenoppia pletzenae, by the body length, different number of cilia on bothridial seta, the relative length of prodorsal setae, the localization of notogastral setae la and lm, and the absence of interbothridial tubercle. An identification key to known species of Pletzenoppia is presented.

Mite Family

The oribatid mite family Hungarobelbidae is widely distributed in the northern hemisphere, but has been represented by only two genera and eight known species. Herein, we propose a remarkable new species, Hungarobelba nortonroyi sp. nov. based on adults from western USA, exhibiting curious mixtures of character states of both genera of this family, Costeremus and Hungarobelba. Based on available data, we assess current views of the family-level classification of Costeremus rejecting its placement in Damaeolidae, and a close relationship is suggested between Costeremus and Hungarobelba. Also, recent transfer of the damaeid genus Tokukobelba to Hungarobelbidae is reversed, as there are no synapomorphies linking the latter two taxa. Furthermore, a brief note on habitat ecology and biogeography of hitherto know species is given, and a key for the identification of adults of the known genera and species of Hungarobelbidae in the world, is provided.

The oribatid mite subgenus Scheloribates (Topobates) Grandjean, 1958, is recorded from the Neotropical region for the first time. A new species of this subgenus is described from the leaf litter collected in Cayo Agua Island, Panama. Scheloribates (Topobates) panamaensis sp. nov. differs from its related species by the very large body size and presence of a strong ventrodistal process on the leg femora II–IV.

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, Cultroribula taigagica sp. nov., collected from cool temperate forests in Northern Mongolia is described based on adults. In addition, three known species, Astegistes pilosus (C.L. Koch, 1840), Cultroribula dentata Willmann, 1950 and Cultroribula vtorovi Krivolutsly, 1971 are recorded for the first time from Mongolia, which are redescribed along with data on their distribution and ecology. A key to Mongolian species of Astegistidae is given.

A New Species

The present study is based on oribatid mite material (Acari, Oribatida) collected from six localities in Ethiopia during 2013. A list of identified taxa, including 60 species from 45 genera and 30 families, is provided; of these, eight species are recorded in the fauna of this country for the first time, and one species is recorded in the Ethiopian region for the first time. A new species of the genus Wallworkoppia (Oppiidae) is described from litter and fallen leaves in a Juniperus forest; W. tetraciliata Ermilov sp. nov. differs from W. secata (Mahunka, 1999), W. parasensilla (Mahunka, 1999), W. tuberosa (Mahunka, 1988) and W. vibrissa (Mahunka, 1983) by the rounded rostrum (versus tripartite rostrum). An identification key to known species of Wallworkoppia is updated.
