Multi-instar descriptions of cave dwelling Erythraeidae (Trombidiformes: Parasitengona) employing an integrative approach.

The life cycle of Parasitengona includes major morphological changes precluding an instar association based only on the morphology. This makes rearing and/or molecular data necessary to associate the heteromorphic instars. Most of the described species are known from either post larval instars or larva.

Monunguis streblida (Neothrombidiidae) in Brazil and its parasitic relationships with dipteran ectoparasites (Anastrebla and Trichobius) of bats.

The mite species Monunguis streblida Wharton, 1938 (Neothrombidiidae) is reported in association with dipteran ectoparasites (Streblidae) of Brazilian bats for the first time. A 1-year study of two populations of the bat Anoura geoffroyi Gray, 1838 in caves in the state of Minas Gerais, Brazil, found them to be parasitized by four species of streblids, three of which were parasitized by M. streblida.

A novel symbiotic relationship between mites and recluse spiders (Sicariidae: ), with a description of a new species (Trombidiformes: Erythraeidae).

This study reports a symbiotic association between an unknown species of Loxosceles (Araneae: Sicariidae) and the adults of a new species of parasitengone mite that lives on their web in Brazilian caves. This mite is described as Callidosoma cassiculophylla sp. nov.

Description of a new species of Oplitis Berlese, 1884, and the first record of a phoretic uropodid mite (Acari: Oplitidae) on a Neotropical solitary wasp (Hymenoptera: Vespidae).

The association of an uropodid mite with a solitary eumenine wasp is reported for the first time. Five mite specimens were found on a specimen of the wasp Zethus pallidus Smith, 1857, collected in southeastern Brazil. The mites are described as a new species, Oplitis ticumbi Kontschán & Bernardi sp.

Post-embryonic development in the mite suborder Opilioacarida, with notes on segmental homology in Parasitiformes (Arachnida).

In order to study homology among the major lineages of the mite (super)order Parasitiformes, developmental patterns in Opilioacarida are documented, emphasizing morphology of the earliest, post-embryonic instars. Developmental patterns are summarized for all external body structures, based on examination of material in four different genera. Development includes an egg, a 6-legged prelarva and larva, three 8-legged nymphal instars, and the adults, for the most complete ontogenetic sequence in Parasitiformes.

An opilioacarid mite in Cretaceous Burmese amber.

A fossil opilioacarid mite (Parasitiformes: Opilioacarida) in Burmese amber is described as ?Opilioacarus groehni sp. nov. This ca.

A new species of Neocarus Chamberlin & Mulaik, 1942 (Opilioacarida, Opilioacaridae) from Brazil, with remarks on its postlarval development.

Neocarus proteus sp. n., is described from caves and the surrounding epigean environment of ferruginous outcrops (Cangas) in Minas Gerais, Brazil.

Bat flies (Diptera: Streblidae, Nycteribiidae) and mites (Acari) associated with bats (Mammalia: Chiroptera) in a high-altitude region in southern Minas Gerais, Brazil.

A total of 71 bat flies belonging to families Nycteribiidae and Streblidae, and 37 mites were collected on 12 species of bats (Phyllostomidae and Vespertilionidae) from the Chapada do Abanador (Minas Gerais, Brazil), between July 2009 and April 2010. Two new occurrences of ectoparasites were recorded on Histiotus velatus (bat fly Basilia producta) and on Carollia perspicillata (mite Parichoronyssus bakeri). Five new occurrences were recorded for the state of Minas Gerais, increasing the range for bat flies Anatrichobius passosi, Paraeuctenodes similis, Basilia juquiensis, Basilia producta and for mite Periglischrus vargasi.
