The Habits and Distribution of Cryptocerus rohweri Wheeler (Hymenoptera: Formicidae)

Abstract: When W. M. Wheeler described Cryptocerus rohweri in 96 he stated that the specimens which Rohwer sent him had been taken by Chrisman in a canyon of the Santa Catalina Mountains o.f Arizona and that they had been nesting in the dead limbs of a palo verde tree (). There was no reason for Wheeler to question that the host tree was Cercidum torreyanum, but this. question has since arisen and it is advisable to consider it here. The. host .plant identification appears to have been made from the dead limb sent in with the ants. Chris.man’s field notes stated only that his. specimens were nesting in "palo verde", which would cover either of the two. species of Cercidium in the Santa Catalina area. But in this area C. torreyanum is scarce and it usually occurs at ele.vations below those where rohweri has been taken. The abundant and widespread species, is C. microphyll,um and all seven c01o,nies of rohweri which we took in the Santa Catalinas were nesting in this tree. The probability is that
