The spectrum of free amino acids in the CNS of 6 spp. from 6 different spider families [Tegenaria derhami (Scopoli) (Agelenidae), Araneus diadematus Clerck (Araneidae), Pardosa amentata (Clerck) (Lycosidae), Marpissa muscosa (Clerck) (Salticidae), Latrodectus mactans tredecimguttatus Rossi (Theridiidae) and the orthognath species Aphonopelma eutylenum (Chamberlin) (Theraphosidae)] was analyzed by microchromatography of dansyl derivatives. Dansyl amino acids (23) were identified and the following ones were relatively abundant in all the species investigated: taurine, alanine, glycine, GABA, proline, glutamic acid and aspartic acid. Results are compared with findings from other arthropod subphyla, and the role of amino acids as putative neurotransmitters in the arthropod CNS is discussed.
