Mites in house dust from brazil

Abstract House dust samples were collected from several localities in Brazil; the distribution and abundance of twenty two species of mites of the families Glycyphagidae, Pyroglyphidae, Chortoglyphidae, Acaridae, Cheyletidae, Bdellidae, Tydeidae, Raphignathidae, Ascidae and of Oribatei, recovered from these samples, is given.

South American Spider Mites: New Hosts and Localities

Abstract In order to contribute to taxonomic information on Tetranychid mites (Acari: Tetranychidae) in South America, surveys were conducted in Brazil (15 States and the Federal District) and Uruguay (one Department); 550 samples of 120 plant species were collected. Tetranychid mite infestations were confirmed in 204 samples, and 22 species belonging to seven genera of the Bryobiinae and Tetranychinae subfamilies were identified on 58 different host plants. Thirty-six new plant hosts were found in Brazil, South America, and worldwide for the following species: Eutetranychus banksi (McGregor); Mononychellus tanajoa (Bondar); Oligonychus anonae Paschoal; O. mangiferus (Rahman and Sapra); Tetranychus bastosi Tuttle, Baker and Sales; T. desertorum Banks, 1900, T. evansi Baker and Pritchard; T. ludeni Zacher; T. mexicanus (McGregor); T. neocaledonicus André; and T. urticae Koch. Four new localities in Brazil were reported for Eotetranychus tremae De Leon; O. anonae; Panonychus ulmi (Koch); and T. gloveri Baker and Pritchard.

Phytophagous and fungivorous mites (Acari: Prostigmata, Astigmata) from Peru

This is an updated checklist of phytophagous and fungivorous mites from Peru (Prostigmata: Tetranychidae, Tarsonemidae, Tenuipalpidae, Tydeidae, Eriophyidae, Diptilomiopidae; Astigmata: Acaridae, Winterschmidtiidae). The data are mainly based on an extensive survey carried out in the Peruvian territory in 2006, as well as on the new records of mites from minor collections and previous records. In addition to the new data collection, the presence of predators associated with the phytophagous mites collected is noted.

Acari domum Meliponinarum brasiliensium habitantes. V: Two new genera and species of Laelapidae (Mesostigmata: Acari) from stingless bee nests

Abstract Melittiphisoides apiarium , n. gen., n. sp. and Hunteria brasiliensis , n. gen., n. sp. (Laelapidae: Mesostigmata) are described and figured from the nests of meliponine stingless bees (Apidae: Hymenoptera) taken in Brasil. These mites are presumably permanent commensals in the bee nests.

Two new spider mites (Acari: Tetranychidae) from Brazil: a Monoceronychus McGregor (Bryobiinae) from fingergrass and an Oligonychus Berlese (Tetranychinae) from grape

ABSTRACT Two new Tetranychidae (Prostigmata) mites are described from Brazil – Monoceronychus tchecensis n. sp., a bryobiine collected from weeping fingergrass, Eustachys distichophylla (Lag.) Nees (Poaceae), in the State of Rio Grande do Sul; and Oligonychus fileno n. sp., a tetranychine collected from grape, Vitis vinifera L. (Vitaceae), in the State of Minas Gerais. Monoceronychus tchecensis n. sp. is the second species in this genus described from South America. In addition to the description of these new species, the tetranychine Eotetranychus smithi Pritchard and Baker, 1955 was recorded for the first time for South America.

A new species of Notostrix (Acari: Eriophyidae), with notes on the host plants and distribution of species of this genus

Thirteen Notostrix Keifer species are presently known, all from leaves of palm trees (Arecaceae) to which they seemingly cause no major damage. A new species of this genus, Notostrix macrothrix sp. nov., is morphologically described based on adult females and males collected from coconut, Cocos nucifera L. (Arecaceae), on La Reunión Island. A discussion about the presently known distribution of mites of this genus is also presented. http://www.zoobank.org/urn:lsid:zoobank.org:pub:14C65CB2-AF56-4D85-AD49-56FA11119EF5

A new Oligonychus and description of the female allotype of Oligonychus psidium Estebanes & Baker (Acari, Tetranychidae) from Qualea grandiflora Mart. (Vochysiaceae) in northwestern São Paulo, Brazil

Oligonychus longipenis, sp.n. and the female allotype of O. psidium Estebanes & Baker, 1968 from Qualea grandiflora Mart. (Vochysiaceae) is described. The male of O. psidium is redescribed in Northwestern Sao Paulo (Brazil). This is the first record for 0. psidium in Brazil.

Acari domum meliponinarum brasiliensium habitantes. VI. New species of Bisternalis Hunter (Laelapidae: Acari)

ABSTRACT Five species of Bisternalis Hunter (Laelapidae) are reported from the nests of stingless bees (Apidae: Hymenoptera) from Brasil, of which three B. camargoi, n. sp., B. formosus, n. sp. and B. trigonarum, n. sp.) are described and figured, and two (B. mexicanus Baker, Delfinado-Baker & Ordaz and B. rettenmeyeri Hunter) are newly recorded from Brasil. The genus Bisternalis now contains six species, all but one (B. hunteri Baker, Delfinado-Baker & Ordaz, from a wasps nest) occur in neotropical meliponine nests. A key to these six species is provided.

Two new eriophyoid mite species (Trombidiformes: Eriophyoidea) from the cocoa tree, and a note on Shevtchenkella biseta (Nalepa)

Two new eriophyoid mite species are described from the cocoa tree, Theobroma cacao L. (Malvaceae) - the Diptilomiopidae Davisella trevisani n. sp. Rodrigues, Navia & Oliveira, from Brazil; and the Eriophyidae Tetra theobromae n. sp. Rodrigues, Navia & Oliveira, from Costa Rica. The new Davisella species presents an enlarged subcylindrical tubercle bearing pedipalp genual seta d, a novel structure for eriophyoid mites; its functional morphology was discussed. The new Tetra species is the third in this genus described from plants of the Malvaceae. A closer look at Shevtchenkella biseta (Nalepa), described from the Malvaceae Hibiscus rosa-sinensis L., showed its taxonomic assignment to the Phytoptidae, Sierraphytoptinae and raised a hypothesis on its synonymy.
