Numerous new data on a total of 165 bee species from the Spanish provinces of Asturias and León are presented, including one (Nomada obtusifrons Nylander, 1848) that had not previously been reported from the Iberian Peninsula, with several first provincial records and information on the plants these species visit. Comments on the distribution range of the most remarkable species are also included. The paper is illustrated with field photographs of specimens in their natural environment, along with images taken through a binocular microscope showing the diagnostic details of some taxa that are either interesting or difficult to determine.

The integration of the residential function beyond the limits of the urban and developable land in the legislative frameworks has had a distinct and incomplete character. Faced with an identical phenomenon in general, called urban sprawl, the competent governments in this matter within the Iberian Peninsula have opted for a dissimilar assimilation of it, materialized in different legal and instrumental mechanisms. The objective of this paper is to present the different ways of understanding and regulating this new urban model by the Portuguese state government and the regional autonomous governments in Spain. To do this, a comparative analysis is carried out on the criteria for the classification of undeveloped land and a review of the most paradigmatic tools for the management of periurban and rurban development. The works indicate a position that is still indeterminate and, sometimes, contradictory. In spite of this, there is a tendency towards the regulated inclusion of the residential function outside the geographical contexts that have traditionally supported it. [ABSTRACT FROM AUTHOR]
