CORTES LOPES, Benedito  e  GORDON FOWLER, Harold. Fungus-growing ants (Hymenoptera: Formicidae) on Santa Catarina Island, Brazil: patterns of occurrence. Rev. biol. trop [online]. 2000, vol.48, n.2-3, pp.643-646. ISSN 0034-7744.

A taxonomic survey on fungus-growing ants (Attini) was made at 14 beaches on Santa Catarina Island (SC), Brazil. The samplings were manual, in soil or litterfall, in the following habitats: sandy beach, herbaceous vegetation and shrubby vegetation. From 12 species of Attini (ten of Acromyrmex Mayr and two of Cyphomyrmex Mayr), the most frequent were Cyphomyrmex morschi Emery and Acromyrmex crassispinus Forel, collected, respectively, on eight and ten of the monitored beaches. Altogether, Sorensen’s similarity coefficients were high (range: 0.59-0.80), in spite of the lower numbers of ant species on sandy beaches
