The tribe Macrodactylini (Coleoptera: Scarabaeidae: Melolonthinae) is distributed throughout the world, comprising approximately 1028 species and 80 genera; the majority of genera are found in the Neotropical Region, where 46 genera occur (Katovich 2008; Fuhrmann 2012; Smith & Mondaca 2015; Fuhrmann & Vaz-de-Mello 2017). The Neotropical genus Compsodactylus Fuhrmann, 2012 was established by Fuhrmann (2012) to include three species, two of them formerly placed in the genus Dicrania Lepeletier & Audinet-Serville, 1828. Compsodactylus is distinguished from other Macrodactylini by the mentum being longer than wide, the posterior area of frons and anterior area of pronotum with denticle-like setae, the protibiae bidentate and with a spur, the external and internal margins of elytra beaded, the metacoxae with a short projection over the base of the trochanter, the male metatibia with an internoapical spine and without spurs, and the abdominal spiracular area VII narrowed (Fuhrmann 2012). Compsodactylus currently includes three species: C. martinezi (Frey, 1972) from Peru, C. parvulus (Frey, 1970) from Bolivia, and C. scabrosus Fuhrmann, 2012 from Argentina. In the survey of Scarabaeoidea of Peru (Ratcliffe et al. 2015), Compsodactylus and the species C. martinezi, which is endemic to the Peruvian departments of Abancay and Cusco, were omitted. Recently, a series of individuals identified as Compsodactylus was collected in the surroundings of a tributary of the Marañón River, in the department of La Libertad, Peru, which corresponds to a species described below.
