Camponotus crassus  is the most frequently recorded Camponotus  from Paraguay. This ant appears to be found in every terrestrial habitat type with woody vegetation of sufficient diameter to house the arboreal nests in hollow twigs. The coloration of the antennal scapes shows slight variation among collections, from testaceous to dark reddish brown. The amount of pilosity on the mesosomal dorsum also varies somewhat. Forel’s type of C. vezenyii  from Asunción is slightly more pilose and has lighter colored scapes than Mayr’s type of C. crassus  , but it still falls well within the range of variation observed in Paraguay and is synonymized here.

Santschi (1936) distinguished the variety C. picticornis  from C. crassus  on the basis of antennal scape color. I was unable to view Santschi’s types of C. picticornis  from Loreto, Argentina  , but several other series from northern Argentina  at NHMB identified by Santschi as C. picticornis  are within my conception of C. crassus  .
