摘要
The species Mycetophylax conformis, M. simplex and Cyphomyrmex morschi, all belonging to the basal Attini, occur exclusively on beaches along the Atlantic shores of South America. In Brazil C. morschi colonies were found sympatrically with the two Mycetophylax species which, however, had no overlap in their geographic distribution. We recorded species-specific nesting site preferences resulting in a zonal colonization of dune and restinga areas, with distinct preferences in microhabitat choice. After excavating subterraneous nests, we were able to describe details of nest architecture, especially with regard to the number and position of the fungus chambers. The nest structure is similar in all species, but the colony size differed with the highest number of workers in M. simplex. All nests were headed by a single mated queen. First attempts were undertaken to maintain colonies under laboratory conditions.
