The Hercules Beetles (Subgenus Dynastes, Genus Dynastes, Dynastidae): A Revisionary Study Based on teh Integration of Molecular, Morphological, Ecological and Geographic Analyses
Published in 2017 and free to download!
Author Jen-Pan Huang elevates most former Hercules ssp to full species status; range maps; identification
A great work on both the white Dynastes (granti, et al) and giant Dynastes (hercules).
Does not cover satanas or neptunus.
Much analysis has gone into study of horn characteristics, and photos are included, but the photos are small and not very useful (my sole complaint). However, the written description of horn characteristics does the trick.
