A preliminary list of the spiders of Cazorla

Abstract

The following records in the Coto Nacional de • las Sierras de Cazorla y Segura were made during an intensive collecting period in May, 1979. Three methods of collecting were used. The first included sweeping herbs and bushes with a sweep-net and beating tree foliage with a beating-tray to sample both those species that make webs on vegetation and those that inhabit flowers and foliage. The second method was by searching the bare ground and under stones and collecting with a pooter. The third method was by using a series of pitfall traps containing ethylene glicol as a preservative to collect nocturnal and ground dwelling species. Eighteen sampling stations were established ranging from the water margin of the Embalse del Tranco, the Rio Guadalquivir valley and its tributaries, the lower elevation woodlands through to the grazed meadows to the karst limestone district at 1700 ni. Five pitfall traps were placed at each of 11 of these sampling stations for a period of 8-10 days. The 3 sampling methods produced essentially a different list of species at each location. The majority of the specimens collected have been identified. Some of these are marked with a question because they are immature and lack positive identification features and others because they do not totally agree with the description of a species and might possibly therefore be some other hitherto undescribed species or subspecies. Several specimens of two families, the Salticidae and Lycosidae, have not been identified yet and will be the subject of a subsequent publication. The species marked with an asterisk are possibly new records for Spain since they do not appear in the comprehensive lists of FERNÁNDEZ GALIANO (1910) or PÉREZ DE SAN ROMÁN (1947).
