Remarks. In Ecuador, C. humidus inhabits coastal evergreen foothill forests (Sierra et al. 1999) below 1500 m, although in Colombia, there are records of this species from 500–1540 m on the foothills of the western and eastern mountain ranges (Fig. 3). Biogeographically it is distributed in the Cauca Province (Morrone 2014).
