Abstract
About 15 years after the publication of the last information on the distribution of the Symphyla in Spain (Dominguez, 1992; Mas & Serra, 1993), new data on eight species are provided. The 148 examined specimens come from two field trips performed in Barcelona province (November 2006) and Minorca (Februar 2007), and from material donated by several researchers. Specimens from the field trips were collected from soil samples using a Kempson apparatus. Since the taxonomic features to identify the symphylan species are often difficult to assess with a light microscope (Turner & Edwards, 1974), most of the specimens were identified with a scanning electron microscope following the keys of Edwards (1959), Scheller (1978), and Dominguez (1992). Data on the distribution of the identified species are sorted by locality, with additional information about date, collectors, environment, altitude, geographic coordinates and sex (if known). Juvenile stages are indicated with the number of pairs of legs (lp). Some remarks on the taxonomic features used for the identification are explained and depicted with SEM-micrographs.

Other taxonomic features are the absence of a ventral process on the femora of the first pair of legs in the females and the presence of one elongate seta on this same area (Fig. 1B)
The triangular appendages of the second (T2) and third (T3) tergite bear a seta between inner basal seta and apical seta
Summary
About 15 years after the publication of the last information on the distribution of the Symphyla in Spain (Domínguez, 1992; Mas & Serra, 1993), new data on eight species are provided. REMARKS: This species is characterized by a distinctly emarginated posterior margin of the second tergite of the trunk and by the homogeneity of the setae on the second tergite (Fig. 1A). Jábaga (Cuenca) (collected by María José Luciáñez, in a Pinus nigra forest): 1 adult (June 2005).
