Ocho de ellas se citan por primera vez para la Península Ibérica: Hypogastrura (Hypogastrura) sahlbergi (REUTER, 1895), Schaefferia ariegica (CASSAGNAU, 1959), Acherongia mínima MASSOUD y THIBAUD, 1985, Friesea albida atypica CASSAGNAU, 1958, Odontellina nivalis (CASSAGNAU, 1959), Neonaphorura cf. novemspina GISIN, 1963, Onychiurus justi DENIS, 1938 sensu GISIN, 1952, Wankeliella mediochaeta RUSEK, 1975, y seis son nuevas para la ciencia: Friesea villanuevai n.sp., Friesea villanuevai populi n.ssp., Pseudachorutes plurichaetosus n.sp., Stachorutes valdealbarensis n.sp., Superodontella conglobata n.sp. y Mesaphorura longispina n.sp. Se incluyen claves para la determinación de las especies

A new species of Entomobrya from Iraq (Collembola, Entomobryidae)

The systematic study of Entomobrya specimens from different museums in the Palaearctic region and material obtained from other collections allowed some new species of the genus to be revealed. Entomobrya iraqensis n. sp. is described from Mosul, Iraq. For the identification and description of the species, the set of characters proposed by Jordana and Baquero (2005) was used

A proposal of characters for taxonomic identification of Entomobrya species (Collembola, Entomobryomorpha), with description of a new species

The species of the genus Entomobrya have bean traditionally identified using colouration. Only some authors have considered a small number of morphological characters, in badly mounted or old specimens, as well as chaetotaxical characters (but not used for species identification). The study of a large series of slides from extensive collections of Entomobrya species with observation of the complete chaetotaxy has demonstrated that specimens with the same colour pattern can have a very different chaetotaxy, which is related with the geographical origin. On the other hand, specimens with similar chaetotaxy but from distant geographical areas maintain the same colour pattern. The present paper proposes a set of both morphological and chaetotaxical characters as a useful tool for the species identification in the genus Entomobrya in connection with the observation of colour pattern. For the selection of this set of characters more than 500 slides from the top-ranking European museums have been studied. Two species of the genus with similar colour pattern but with a different chaetotaxy are used as models for the methodology: E. nivalis (Linnaeus, 1758) and a new species from León (Spain)."By kind permission of Senckenberg Museum für Naturkunde Görlitz; copyright by Senckenberg Görlitz.

A new species of Entomobrya (Collembola, Entomobryidae) from La Caldera de Taburiente National Park (La Palma Island, Canary Islands) and its associated collembolan fauna

Entomobrya palmensis n. sp. is described from the Canary Islands (Macaronesian Region). The new species shares the colour pattern with E. multifasciata (Tullberg, 1871), but clearly differs in chaetotaxy. A list of species and locations of the collembolan fauna of the area is given

New species of Pseudosinella Schäffer, 1897 (Collembola, Entomobryidae) from Spain

The revision of the specimens of Pseudosinella at the Bonet Collection (MNCN, Museo Nacional de Ciencias Naturales- CSIC, Madrid) have allow us to describe four new species found among 175 slides with more than 420 specimens. One of them belongs to the petterseni-group (unguiculus with a fully developed tooth and without eyes). The differential characters of Pseudosinella species from Christiansen (2007), and four characters more, have been used for comparison with the related species

The Genus Gonatocerus Nees (Hymenoptera Chalcidoidea Mymaridae) in Corn Fields of Navarra, North Spain

Eight species of Gonatocerus Nees, 1834 (Hymenoptera Chalcidoidea Mymaridae) are added to the faunallist of Spain: G. li/oralis (Haliday, 1833 ), G. chrysis Debauche, 1848, G. /hyrides Debauche, 1848, G. longior Soyka, 1946, G. sulphuripes (Forster, 1847), G. pic/us (Haliday, 1833 ), G. minor Matthews, 1986 and G. Dvicena/us Leonard and Crosby, 1915. Species descriptions and details about their distribution and biology are also included. The name G. tremulae Bakkendorf, 1934 is synonymized under G. Dvicena/us. The specimens were collected with a Malaise trap in Cadreita, and with a sweep net in sixty corn fields from 23 localities around Navarra

A disjunct distribution for a new species of Orchesellides (Collembola, Entomobryidae, Orchesellinae)

A new species of Orchesellides is described from material collected in the Valsa n forest (Segovia, Spain), and conserved in the collection of the National Museum of Natural Sciences (MNCN), CSIC, Madrid. The genus was known only from the eastern Palaearctic, Oriental, and Indo-Pacific (Hawaii) regions. This is the first reference for the genus from the western Palaearctic region, creating an interesting disjunct distribution. The value of the morphological characteristics for the identification of the species is discussed

Two new species of Entomobrya (Collembola, Entomobryomorpha) from the cave collembolan collection of Bonet from Asturias and Cantabria (north of Spain)

Two new species of Entomobrya are described from two caves of Asturias and Cantabria (north of Spain). The specimens were found in the Bonet collembolan collection at the “Museo Nacional de Ciencias Naturales” of Madrid (Spain). Entomomobrya boneti n. sp. was found in three slides containing 11, 4 and 1 specimens respectively, from the “Cueva del Castillo”, Puente el Viesgo (Santander). Entomobrya luquei n. sp. was found in a slide with 11 specimens from “Cueva de Cuetu-Lledías”, Llanes (Asturias). The species are described considering a set of 39 morphological and chaetotaxy characters. Both species appear to be troglophiles by the pigment reduction, although there are no other troglomorphic characters present. The gut content is composed of organic matter and fungus spores
