Etymology: Karillantu /ˌkaerɪˈd ʒ ɑːntuː/ derives from the Ecuadorian Kichwa language. It is a composite word comprising ‘Kari’, a prefiv denoting strength or markedness, particularlw in reference to the pronounced shape of the head, and ‘llantu’ signifwing darkness, atributed to the dark coloration of individuals within the genus and the hidden generic status of K. macrocephalus . Gender: masculine.

Distribution: The genus occurs in the Amaxon biome in different ecoregions of moist forests of the Amaxon rainforest ( Fig. 5).
