Oribatid mites (
Our investigation is based on Peruvian material collected during a one-month German Expedition organized by Bavarian State Collection of Zoology in September (second half) and October (first half) 2011. The primary goal of the paper is to present the checklist of the identified species with new records for Peru as well as for the Neotropical region.
In the course of taxonomic identification, we found one new species of the genus
Samples were collected from six localities in Peru, Panguana, basin of the Río Yuyapichis (
Locality 6, rotting wood, 26.09.2011;
Locality 12, forest litter, 29.09.2011;

Specimens were mounted in lactic acid on temporary cavity slides for measurement and illustration. The body length was measured in lateral view, from the tip of the rostrum to the posterior edge of the ventral plate. The notogastral width refers to the maximum width in dorsal aspect. Lengths of body setae were measured in lateral aspect. All body measurements are presented in micrometers. Formulas for leg setation are given in parentheses according to the sequence trochanter–femur–genu–tibia–tarsus (famulus included). Formulas for leg solenidia are given in square brackets according to the sequence genu–tibia–tarsus. Microscope figures were made with a drawing tube using a Carl Zeiss transmission light microscope “Axioskop-2 Plus”. General terminology used in this paper follows that of Grandjean (summarized by
This annotated checklist includes the specific localities where oribatid mites were collected, and notes new records and overall known distribution
In the course of the taxonomic studies of materials, we identified 16 species belonging to 14 genera and 8 families. Of these, 13 species and two genera,
Body size: 531–697 × 365–448. Body surface punctate and with striate bands. Rostrum pointed. Rostral, lamellar and interlamellar setae well developed, barbed. Bothridial setae setiform, ciliate unilaterally. Lamellar and sublamellar lines parallel, curving backwards. Anterior notogastral margin not present. Notogaster with three pairs of porose areas:

Roman letters refer to normal setae (ɛ to famulus), Greek letters to solenidia. Single prime (‘) marks setae on anterior and double prime (“) setae on posterior side of the given leg segment. Parentheses refer to a pair of setae.
The holotype is deposited in the collection of the Senckenberg Institution Frankfurt, Germany; three paratypes are deposited in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia; one pratype is deposited in the collection of the Natural History Museum, Lima, Peru.

We are very grateful to Prof. Dr. Badamdorj Bayartogtokh (National University of Mongolia, Ulaanbaatar, Mongolia) for the valuable comments, Dr. Juliane Diller and Erich Diller (Bavarian State Collection of Zoology, Germany) for permission to work in the Panguana Research Station in Peru and for providing logistic support. The reported study was supported by the Russian Foundation for Basic Research (project: 15-04-02706 A).
Ptyctimous mites are not included in the checklist.
