Biogeographically it is distributed in the Cauca Province ( Morrone 2014).

Seven species of Cryptocanthon Balthasar, 1942 are now known from Ecuador: C. curticrinis Cook, 2002 ; C. genieri Cook, 2002 ; C. humidus (new country record), C. napoensis Cook, 2002 ; C. otonga Cook, 2002 ; C. paradoxus Balthasar, 1942 , and C. urguensis Cook, 2002 ( Cook 2002; Chamorro et al. 2019).
