Abstract

Sampling of arthropod fauna by pitfall traps in the cavern 'Sima de San Rafael' in Íllora (Granada, Spain) has revealed a new carabid beetle species, Trechus parapandus n. sp., with remarkable troglobiomorphic characteristics: eyes visible only as scars, depigmentation, and elongation of antennae and legs. In consonance with these characteristics, this new species, Trechus parapandus n. sp. is absent in the upper region of the cave. The species belongs to the Trechus fulvus species group (that has five species in Andalusia) according to the characteristics of both male and female genitalia. Study of the fauna in the cave suggests that Collembola might be the prey of this new species since they are the most abundant group and have a coincidental phenology. A key for the 11 Trechus species present in Andalusia is provided.
