Hypoproct with three setae. Comments . The examined specimens of C. palpalis from Costa Rica , Brazil (Rondonia) and Ecuador have a longer patch of setulae on the anterior face of the forefemur, similar to a stripe (fig. 16), differently from the holotype that has an oval patch (fig. 15). They were not considered a different species as no other significant differences were found.
