Vol. 1 1 5. No. 4. September & October 2004 229 A NEW GENUS AND SPECIES OF ENTOMOBRYIDAE (COLLEMBOLA, ENTOMOBRYOMORPHA) FROM THE IBERIAN PENINSULA Enrique Baquero, : Maite .Martinez, 2 Kenneth Christiansen,' and Rafael Jordana 2 ABSTRACT: A new genus and species, Hispanobryu hairancoi Jordana and Baquero, gen. n., sp. n. is described. It was found in the Gador Mountain range (Almeria, 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 simi-lar to that of the genus Capbrya. KEY WORDS: Collembola, Entomobryomorpha, Entomobryidae, Hispanobtya gen. n., Spain, Iberian Peninsula Specimens of an undescribed collembolan with characteristics of both the families Entomobryidae and Isotomidae were found during a study of the cave fauna of Almeria (south of Iberian Peninsula). Their habitus, length of abdomi-nal segments III and IV, presence of PAO led to an initial identification as Isotomurus. Detailed study, including SEM (Scanning Electron Microscopy) observation, allowed us to see characters not visible under the light microscope. These details included the eye fine structure, claw, unguiculus, and body sculp-ture. As a result of this study it became clear that these specimens were a new genus similar to the genus Capbiya Barra, 1999, from South Africa. METHODS The specimens were collected in the "Paraje Natural Karst en Yesos de Sorbas" in Almeria, Spain. The plant community of the "Paraje Natural Karst en Yesos de Sorbas" is gypsophilous and is dominated by small bushes of Thymus spp. (thyme, Lamiaceae). There are few other plants near these. In the more open regions, where the thyme is less dense, there is a scattering of annual plants (La-zaro, 1986). The remaining soil is covered mainly by lichens, which cover about 90 percent of the gypsum surface. The predominant lichen community is Helian-terno alypoidis-Gypsophiletum stnithii (Rivas-Goday and Esteve, 1965). Samples were taken in the spring, summer and autumn, but Hispanobrya gen. n. was found only in the spring and summer. Specimens were preserved in 70 percent ethanol. Some specimens were mounted on slides using 'Hoyer medi-um,' whereas others were dehydrated using an ethanol series followed by criti-cal-point drying in CO 2 , mounted on aluminum SEM stubs, and coated in Argon 1 Received on August 4, 2004.
