A New Species

A new species of oribatid mites of the family Cepheidae is described based on adults from rainforest in Chile. Sadocepheus nortonroyi sp. nov. differs from Sadocepheus foveolatus by the larger body size, the presence of transverse notogastral ridge and divergent lamellar cusps, and the location of notogastral setae on the notogastral surface. Explanations on placement of some species in Sadocepheus are presented. An identification key to known species of Sadocepheus is given.

A New Species

The description of a new species of oribatid mites (Oribatida) of the family Zetorchestidae—Zetorchestes krisperi sp. nov.—is proposed based on adult and tritonymph specimens collected from rainforest soil of Bi Dup-Nui Ba National Park (southern Vietnam). We also review the distinguishing characteristics for Zetorchestes species and present an identification key to Zetorchestes species of the world. Diagnostic features of Zetorchestes nymphs are discussed.

Diagnostic Traits

A new species of the genus Meristolohmannia (Oribatida: Lohmanniidae) is described from litter of a secondary forest in Macao of southern China; M. macaoensis Ermilov sp. nov. differs from M. abbreviata Chen, Yang & Xie, 2010 by the comparatively longer rostral setae than the lamellar, interlamellar and posterior exobothridial setae, bothridial setae with well-developed branches, reticulate notogaster surface, number and morphology of subcapitular setae, nine pairs of genital setae and the smaller body size. An identification key to the known species of Meristolohmannia is provided. Lohmannia (Lohmannia) corallium Nakatamari, 1982 is recorded in the Oriental region for the first time; its supplementary description is provided based on material from China, and the revised diagnostic traits for this species are also proposed.

A new species of oribatid mite of the family Galumnidae is described and illustrated based on adult specimens from soil in Mashhad county, Razavi Khorasan Province, northeastern Iran. Pilogalumna khorasanica sp. nov. is characterised by rounded rostrum; very long interlamellar setae; long, nearly setiform, finely bilaterally barbed bothridial setae; medially interrupted dorsosejugal furrow; elongated porose areas A2, very long and narrow, ribbon shaped A3 and large body size. The new species is most similar morphologically to Pilogalumna crassiclava longiareata (Pérez-Íñigo, 1976), however, differs from it in morphology of bothridial setae and structure of notogastral porose areas, by the presence of longer interlamellar setae and larger body size. An updated identification key to known species of Pilogalumna is presented.

AbstractA list of identified oribatid mites of the family Lohmanniidae (Acari, Oribatida) collected from Cuba, including 4 species from 4 genera, is provided. The genus Heptacarus and species Heptacarus supertrichus Piffl, 1967 are recorded in Cuba for the first time. A new species of Annectacarus is described from leaf litter in forest of Valle de Viñales National Park. Annectacarus vinalesensis sp. n. is morphologically most similar to A. krachan Mahunka, 1995, but the new species differs from the latter by the rostrum with indentation and the presence of six pairs of neotrichal notogastral setae and six pairs of setae on epimere I. An identification key to the known species of Annectacarus in the Neotropical region is given.

Two new species of oribatid mites of the family Lohmanniidae are described from litter in the mixed forest of Zanzibar, Tanzania. Annectacarus tanzanicus sp. nov. differs from Annectacarus vinalesensis Ermilov & Tolstikov, 2015 by body size, the number of neotrichal notogastral setae, porose parts on the notogaster and branches on bothridial setae, and the localization of rostral setae. Strinatacarus zanzibarensis sp. nov. differs from Strinatacarus aelleni Mahunka, 1977 by body surface and length of some notogastral setae. Tritonymphal instar of Annectacarus tanzanicus sp. nov. is also described. An identification key to the known species of the genus Annectacarus from the Ethiopian region is presented.
