Throat gray, dewlap light orange, venter greenish gray. Iris brown. Tongue light ; Juan Manuel Renjifo has supplied color notes on ICN 5912 from the Rio Amparrad6 region: Greenish brown with bars of lighter greenish brown forming chevrons on the middle of the back. Labials and flanks rosy salmon. Venter yellowish cream. Gular sac white. One entry in Scott's field notes cites an unspecified rivalis from Belen as having an orange dewlap. There would appear to be a range of dewlap colors in this species. Habitat and Habits. At Quebrada San Lorenzo, Scott reports A. rivalis both to be less common and to occur on small rocks near the bottom of pools rather than on the huge moss covered boulders preferred by A. maculigula. They escaped by running from rock to rock over the water surface. Some were taken at night sleeping on.
