Remarks

Aegognathus dulima is the second Colombian species of this genus; it was recently described by Cáceres et al. (2019) and represents the first description for Aegognathus after the important contributions published by Arnaud and Bomans between 2000 and 2010 . Besides being the second species of the genus known from Colombia, it is the one with the highest altitude record, collected close to 3000 m asl, in the proximity of the snow-capped mountain ′ Nevado del Tolima ̍, located in a region of high conservation value . Until now only the holotype male was known. For the complete description see Cáceres et al. (2019).
