ABSTRACT The nesting behaviour of Melitoma ameghinoi was studied in the province of Chacoı Argentina. Contrary to other Melitoma speciesı which are known to nest on banks or other vertical or sloping surfacesı the nests were found on horizontal groundı in extremely hard clay soil. The nests were shallowı with three to four vertical cells. The short turrets pointed upwards for a short stretch and then were strongly curvedı with the entrance directed towards the soil surface. The floral relationships of this species were studied by pollen analysis of faeces from cellsı a pollen massı scopal loads of specimensı and direct observation of floral visits. Pollen counts and field observations indicate that M. ameghinoi collects pollen exclusively from Ipomoea species. A compilation of pollen sources for species of Melitoma is presented. All known speciesı including M. ameghinoi ı fall in the category of narrowly oligolectic. A discus- sion of the taxonomic relationships of the species is presentedı and a lectotype is designated.
