Distribution of microarthropods across altitude and aspect in the sub-Antarctic: climate change implications for an isolated oceanic island

Elizabeth A. Hugo-Coetzee & Peter C. Le Roux
Current climate change is altering the distribution of species across both broad and fine scales. Examining contemporary species distributions along altitudinal gradients is one approach to predicting species future distributions, as species occurrence patterns at cold, high altitudes are expected to resemble the species distribution patterns currently observed at warmer, lower altitudes if warming occurs. Strong changes in climate have been observed in the sub-Antarctic over the last 50 years, with a 1.5 °C increase...

An amazing sub-cambium flat mite from South Africa (Acari: Trombidiformes: Tenuipalpidae)

Edward A. Ueckermann, Ronald Ochoa, Gary R. Bauchan & Stefan Neser
An unusual sub-cambium flat mite, Phytoptipalpus occultuae sp. n., first found under the bark in blisters on stems of Senegalia caffra in Pretoria, South Africa is described and illustrated herein. This is a unique species in the genus Phytoptipalpus because of the presence of reduced legs IV, a possible link between those with 4 pairs and 3 pairs of legs. A key to all of the Phytoptipalpus species is given.

Effects of temperature on a Chinese population of Amblyseius andersoni (Acari: Phytoseiidae) fed with Tetranychus urticae

Yu-Jing Li, Qing-Yan Liu, Jing Chang, Yong-Hong Jia & Rui-Xia Meng
The development and fecundity of Amblyseius andersoni (Chant) fed with Tetranychus urticae Koch was studied at five different temperatures (17, 20, 25, 30 and 35 °C) and life parameters of the population were calculated. The development, reproduction, longevity, and life table parameters of A. andersoni were significantly affected by the different temperatures. The duration of the egg, larval, protonymph, deutonymph and total immature stages were reduced when the temperature increased. The total oviposition of A....

Cytological evidence for automictic thelytoky in parthenogenetic oribatid mites (Acari, Oribatida): Synaptonemal complexes confirm meiosis in Archegozetes longisetosus

Paavo Bergmann, Michael Laumann, Roy A. Norton & Michael Heethoff
Diplo-diploid parthenogenesis (thelytoky) is a widespread phenomenon in the mite taxon Sarcoptiformes, and is unusually frequent in the suborder Oribatida, where it characterizes almost 10% of extant species, including whole genera and families. Based on molecular and cytological data, terminal fusion automixis with an inverted meiotic sequence based on holokinetic chromosomes has been suggested as the reproductive mode in these mites. However, unequivocal structural evidence for meiosis is missing. The model organism Archegozetes longisetosus, a...

Climatic and cultivar effects on phytoseiid species establishment and seasonal abundance on citrus

Sharon Warburg, Roni Gafni, Moshe Inbar, Shira Gal, Eric Palevsky & Asaf Sadeh
The structure of phytoseiid communities on citrus varies among orchards and seasons, with potential implications for biocontrol services. Such variation may be driven by meteorological conditions and cultivar-specific traits. We conducted an outdoor seedling experiment to determine the effects of different cultivars on the establishment of introduced predatory mites (Euseius stipulatus and E. scutalis) and colonization by naturally occurring phytoseiids (Amblyseius swirskii, Iphiseius degenerans, and Typhlodromus athiasae) across seasons. Euseius stipulatus persisted through the spring...

Paraquanothrus n. gen. from freshwater rock pools in the USA, with new diagnoses of Aquanothrus, Aquanothrinae, and Ameronothridae (Acari, Oribatida)

Roy A. Norton & Elizabeth Franklin
Many taxa of mites inhabit long-lived freshwater environments, but the few known to live in small, ephemeral rock pools (lithotelmata) are brachypyline Oribatida. One of these is in the South African genus Aquanothrus (Ameronothridae). We describe adults and juveniles of two new rock-pool species from the USA and propose the sister-genus Paraquanothrus n. gen. to include them. The type-species, Paraquanothrus grahami n. sp., inhabits shallow weathering-depressions (‘pans’) on barren sandstone in the Colorado Plateau, especially...

Two new species of the genus Ausoribula (Acari, Oribatida, Oribatulidae) from termitaries of South Africa

Sergey G. Ermilov, Elizabeth A. Hugo-Coetzee & Alexander A. Khaustov
Two new species of oribatid mites of the previously monotypic genus Ausoribula Lee, 1992 (Oribatulidae) are described from termite nests of South Africa. Ausoribula termitophila n. sp. has a pointed rostrum, elongately fusiform, bothridial setae, a weak anterior notogastral margin which only slightly protrudes into the prodorsum, notogastral setae c2 similar in length to other setae (except shorter c1) and three or four pairs of genital setae. In contrast, A. quagesetosa Lee, 1992 has a...

The marine-associated lifestyle of ameronothroid mites (Acari, Oribatida) and its evolutionary origin: a review

Tobias Pfingstl
Existing literature on marine associated Ameronothroidea is reviewed and recapitulated. Although these littoral oribatid mites strongly resemble typical terrestrial mites, they have evolved different adaptions of various kinds to the marine littoral environment. In order to cope with intertidal wave action, most species show reduced and compact sensilla as well as sickle-shaped and elongated claws. Complex cerotegument based plastron mechanisms have evolved to allow breathing under flooded conditions and enabling these organisms to survive an...

An expanded description of the threatened tree kangaroo tick Ixodes (Sternalixodes) dendrolagi Wilson, 1967 (Acari: Ixodidae) from Papua New Guinea

Mackenzie L. Kwak
Little is known about the enigmatic tree kangaroo tick (Ixodes dendrolagi Wilson, 1967). Since its description, no new taxonomic data describing it have been published. An updated description of the morphologically variable female I. dendrolagi is presented based on two specimens taken from the type host at the type locality. Scanning electron micrographs are presented with comments on morphological variation in I. dendrolagi. The conservation of the species is also discussed.
