“…This is based on mites' inability to fly and the lack of evidence that mechanisms known to disperse extant species over long distances are likely to be significant in the distribution of those collected. For example, no phoretic relationships have been established, and while it has been shown that if oribatids are dispersed over long distances by wind, it is mainly tree-dwellers that are transported (Pfingstl, 2017); extant representatives of Marcacocha taxa inhabit soil, litter and lowgrowing plants (e.g., Hammer, 1961;Behan-Pelletier and Eamer, 2003b;Ermilov and Gwiazdowicz, 2015). Furthermore, although the major component of the fossil assemblage, Hydrozetes, is an aquatic taxon, it is not adapted for swimming and disperses by crawling.…”

“…Extant representatives of the remaining mite taxa extracted at Marcacocha occur in wet habitats, but are almost all classed as terrestrial because they are inactive when submerged (Table 1); the exception is the genus Zetomimus, a ceratozetoid, which is considered to be aquatic as it needs water for all life activities, despite being able to survive dry periods (Behan-Pelletier and Eamer, 2007). Apart from Siculobata, the taxa have been previously recorded in Peru from wetland habitats that might have existed previously around the lake basin (Hammer, 1961, Ermilov andGwiazdowicz, 2015). Most mites originating from terrestrial habitats will enter water bodies via secondary transport mechanisms; localized movement of specimens at Marcacocha could have been the result of run-off from the surrounding landscape or collapse of the lake margin, but introduction by falling from (or with) overhanging branches is unlikely due to the absence of trees and shrubs close to the lake.…”

The ability of sedimentary proxies (especially dung fungal spores) to reflect the past presence and density of large herbivores on a landscape has been receiving increasing scrutiny. Here we examine the Sporormiella spore record from a well-dated, multiproxy, highly organic sedimentary record from the small lake basin of Marcacocha in the Cuzco region of Peru. The basin, a wetland since ca. AD 1840, existed as a small lake for at least 4000 years prior. Previous work at Marcacocha has shown that changes in herbivore densities reflect the abundances of oribatid mites preserved in the lake sediments. This study tests the assumption that both the Sporormiella and the oribatid mite records responded in broadly the same way to changes in herbivore densities over the past 1200 years. Analysis reveals a very low covariance between concentrations of Sporormiella spores and the two major components of the oribatid mite assemblage: a single aquatic species of Hydrozetes and a less abundant, wider grouping comprising members of the mostly terrestrial superfamily Ceratozetoidea (referred to as the 'ceratozetoids'). Variations in the Hydrozetes assemblage clearly dovetail with known historical events, including the massive decline of indigenous and camelid populations following the collapse of the Inca Empire in the mid-sixteenth century. Comparison with other environmental proxies from the Marcacocha sequence, including diatoms and charophyte oospores, suggests that the ceratozetoids appear to reflect increasing terrestrialization. In contrast, although the Sporormiella record indicates the presence of livestock, it fails to register the major historical changes in herbivore presence, though reflects well episodes of lake-level lowering. In small lake settings, therefore, the use of Sporormiella to estimate the density of herbivores in the catchment might be considered a relatively blunt instrument when compared with some other indicators.

Two new species of oribatid mites of the genus Protoribates (Oribatida, Haplozetidae) are described based on adult specimens from upper soil and leaf litter in a primary evergreen lowland rainforest in Amazonian Peru. Protoribates curvicarinatus sp. nov. is morphologically most similar to P. antillensis Mahunka, 1985, but differs by the morphology of bothridial setae and length of interlamellar setae and lamellae. Protoribates paraecuadoriensis sp. nov. is morphologically most similar to P. ecuadoriensis Ermilov, Bayartogtokh, Sandmann, Marian and Maraun, 2013 from Ecuador, but differs by the morphology of tarsi I and II and localization of lamellar setae. Three species of Oripodoidea -Unguizetes incertus (Balogh and Mahunka, 1969), Perscheloribates rostratus (Hammer, 1958) and Benoibates borhidii Balogh and Mahunka, 1980 -are recorded in Peru for the first time.

The present study is based on oribatid mite material (Acari, Oribatida) collected during an expedition to Amazonian Peru in May 2015. A list of identified taxa, including 56 species from 36 genera and 23 families, is presented; of these, eight species (Neoamerioppia phoretica, Ceratorchestes globosus, Truncozetes ecuadoriensis, Drymobates silvicola, Dynatozetes amplus, Scheloribates elegans, Allogalumna antillensis, Galumnopsis secunda), five genera (Drymobates, Dynatozetes, Allogalumna, Sacculogalumna, Galumnopsis) and two families (Drymobatidae, Galumnellidae) are recorded in Peru for the first time, the genus Sacculogalumna is recorded in the Neotropical region for the first time. A new species of Sacculogalumna (Galumnidae) is described; S. hexasacculata Ermilov sp. n. is similar to S. samarensis Ermilov et Corpuz-Raros, 2017, but differs by the presence of striate pattern on dorsal and ventral sides of body, rounded rostrum, smooth bothridial setae, complete sejugal suture, short and thin anal and adanal setae, setiform genital and central epimeral setae and two setae on anterior edges of genital plates, and the paraanal position of adanal lyrifissures in females and males.
