ABSTRACT
The community of larval Lepidoptera which feed a&Santolina chamaecypañssiis is specially remarkable. The genus Santolina (Compositae) is known for its high endemicity, restricted distribution in the western Mediterranean Basin, forb-like architecture and rich variety of secondary compounds in the leaves and flowers.
The entomofauna tropliically associated with Santolina is poor both in tenns of diversity and abundance: larvae of 15 species of lepidoptera were collected on the genus Santolina, and additional references to only a ñirther 8 species feeding on this plant were reviewed from literature. Most of these 23 species are, as far as is known, restricted to Santolina or to Santolina closely related plant genera. A high percentage of the Lepidoptera considered here are endemic to the Ibero-Maghrebian área or have distributions in the westem Mediterranean Basin.
Details on parasitoids are specially interesting. Gelis albicinclits (Ruthe, 1859) (Ichneumonidae) is reported for the fírst time from the Iberian Peninsula. Five new host-parasitoid relationships are established and some data on the hiperparasitoids Chalcidoidea (Eulophidae: Entedoninae, Tetrastichinae) are also reported.
