    A new genus and species of Entomobryidae (Collembola, Entomobryomorpha) from the Iberian peninsula
    (American Entomological Society, 2004) Baquero-Martin, E. (Enrique); Jordana, R. (Rafael); Christiansen, K. (Kenneth); Martinez, M. (Maite)
    A new genus and species, Hispanobrya barrancoi Jordana and Baquero, gen. n., sp. n. is described. It was found in the Gador Mountain range (Almer a, Spain). This genus is similar to Capbrya Barra, 1999, from South Africa. The distinguishing characteristics of the new genus are the presence of a post-antennal organ (PAO), no clear tenent hair, a characteristic unguis, the presence of a reduced trochanteral organ, and flattened body setae. The distribution of the bothriotricha is similar to that of the genus Capbrya.

    Redescription of Nothobrya schubarti Arlé, 1961 (Collembola, Entomobryomorpha)
    (American Entomological Society, 2004) Baquero-Martin, E. (Enrique); Jordana, R. (Rafael); Christiansen, K. (Kenneth)
    Three paratypes of Nothobrya schubarti Arl , 1961 were examined in connection with a forthcoming description of a new genus of Entomobryidae. Some of the features observed by Arl in 1961, appeared similar to those of the new genus. These included: small size, color, the presence of PAO, a falciform mucro, the trochanteral organ and the body setae. Observation of a specimen with SEM allowed us to see the PAO and the other characteristics described by Arl in more detail, but other features not described by him were seen which indicate that the genus belongs in subfamily Orchesellinae.
