A new species of Reticulolaelaps Costa (Mesostigmata: Laelapidae) from the iberian peninsula, with a key to world species

A new species, Reticulolaelaps caditanus n. sp., is described based on adult females found in an oothecal cell of Mantis religiosa. The species has several morphological characteristics, including the presence of presternal shields, endopodal III-IV widely connected with sternal shield, 50 pairs of dorsal setae and at least 11 setae "x", curly and barbed, and thin and smooth ventral setae including six pairs of setae on the genitoventral shield. A revised diagnosis of the genus with the addition of new characters and a key to the world species of the genus are provided

A new species-group with new species of the genus Lasioseius (Acari: Mesostigmata: Blattisociidae) associated with neotropical hispine beetles in furled leaves of Heliconia

A new species-group of Lasioseius is described from adults and immatures of four newly described and one undescribed species associated with hispine beetles of the genera Cephaloleia and Chelobasis and other gamasine mites in the furled leaf habitat of Heliconia and related Zingiberales plants. The species-group presents a suite of apomorphic attributes placing it in the subgenus L. (Lasioseius). Adults and immatures were found moving freely on and off the beetles when the latter were exposed from their habitat. Larviparity is indicated by adult females gravid with fully developed larvae. Limited data suggest considerable host specificity between mites and their beetle hosts, indicating that there may be a vast diversity of these mites associated with hundreds of species of hispine beetles in the Neotropical Region. Keys are provided to currently accepted species-groups of Lasioseius and to the species within the new species-group

A new species of Polydiscia (Acari, Prostigmata, Tanaupodidae) with reference to its host: a new species of Deuterosminthurus (Collembola, Symphypleona, Bourletiellidae)

During the sampling campaign to describe the Iberian fauna of Collembola, an undescribed species of the family Bourletiellidae living on Genista hispanica L. was found with parasitic mites. The attached parasitic mites were identified as the larval instar of a new species of Polydiscia, a prostigmatid mite of the family Tanaupodidae Thor, 1935. The genus was previously cited in Austria. The Collembola, Deuterosminthurus bisetosus sp. nov, which was found in distant localities on the Iberian Peninsula, and Polydiscia deuterosminthurus sp. nov., are both here described. Both species were found together on Genista for three consecutive years. The abundant material obtained has allowed us to study both species with SEM (Scanning Electron Microscopy), and show characteristics in greater detail than has been possible with light microscopy

First records of Endeostigmata and Sphaerolichina mites (Acari: Sarcoptiformes and Trombidiformes) from the Iberian Peninsula and the Canary Islands

Un total de siete familias, 14 géneros y 16 especies han sido recolectados en robledales y pinares de Navarra (Norte de España) y otros biotopos de las Islas Canarias. Se adjunta una clave para la identificación de las familias y géneros de estudio

New records of zerconid mites from the Iberian Peninsula and the Macaronesian region (Acari: Mesostigmata: Zerconidae)

ABSTRACT Based on material collected from different habitats (natural, reforested and felled habitats) of Navarra (northern Spain), five species of the family Zerconidae are newly recorded and a key to the 29 species found in the Iberian Peninsula and the Macaronesian region, based on adult females, is provided. Ecological requirements, in terms of habitat preference, vertical distribution in the soil, and seasonal population changes of several species, are given.RESUMEN Nuevas citas de ácaros zercónidos para la Península Ibérica y la región Macaronésica (Acari: Mesostigmata: Zerconidae) Sobre material recolectado en diferentes habitas (naturales, bosques de reforestación y talados), de Navarra (Norte de España), se citan por primera vez para la fauna española cinco especies de la familia Zerconidae y se aporta una clave sistemática para hembras adultas de las 29 especies encontradas en la Península Ibérica y región Macaronésica. Para las especies más importantes se detallan algunos requerimientos ecológicos, tales como preferencia de hábitat, distribución vertical en el suelo y cambios estacionales de su población

Composición, estructura y diversidad de la comunidad de Ácaros Mesostigmata de un hayedo natural (Fagus sylvatica) del sur de Europa

RESUMEN Se estudia la composición específica de la comunidad de ácaros Mesostigmata en una hayedo (Fagus sylvatica L.) de Navarra (España, Sur de Europa). Se han identificado 653 ácaros procedentes de 12 muestras. Estos representan a 41 especies de 14 familias y las especies más abundantes son Paragamasus ponantinus Athias-Henriot, 1967; Vegaia nemorensis (C. L. Koch, 1839); Paragamasus rothamstedensis Bhattacharyya, 1963 y Rhodacarus coronatus Berlese, 1921. La mitad de la comunidad habita en el horizonte húmico del suelo. En este hayedo el valor de la diversidad de Shannon (H´ log2) es 4,42 y el de la equitabilidad (J´) 0,82.ABSTRACT Species composition, structure and diversity of the soil Mesostigmata mite community in a natural beech forest (Fagus sylvatica) from southern Europe Species composition, structure and diversity of the soil Mesostigmatid mite’s community was studied in European beech forest (Fagus sylvatica L.) in Navarra (Spain, southern Europe). Twelve samples were taken and 653 mites were identified. They represented to 41 species from 14 families, the most abundant species being Paragamasus ponantinus Athias-Henriot, 1967; Veigaia nemorensis (C. L. Koch, 1839); Paragamasus rothamstedensis Bhattacharyya, 1963 and Rhodacarus coronatus Berlese, 1921. Haft part of the mites community inhabits the humic layer of the soil. The value of the Shannon’s diversity index (H´ log2) in the forest studied is 4,42, and the equitability (J´) is 0,82
