6A4C87E4FF80652B16C94208FE6E711A.taxon	distribution	Distribution (Fig. 26). New provincial records were discovered as follows. Argentina: Córdoba: Departamento de Calamuchita: “ El Sauce ”; Argentina: Misiones: Departamento Capital: Itambé Miní. This species was previously known from Catamarca, Salta, and Tucumán in Argentina. Note. Fuhrmann (2019) noted that the pronotum of Compsodactylus parvulus (Frey, 1970) is dark brown and sometimes the lateral angles and posterior margin have yellow maculae. This same pattern was observed in some specimens of C. argentinus.	en	Fuhrmann, Juares, Smith, Andrew B. T.

6A4C87E4FF81652E16C947C6FD6E750E.taxon	etymology	Etymology. From the Latin mendax meaning liar, in reference to the elongate clypeus being reminiscent of Pinocchio’s nose. This name is a noun in apposition.	en	Fuhrmann, Juares, Smith, Andrew B. T. (2021): Compsodactylus Fuhrmann, 2012 (Coleoptera: Scarabaeidae: Melolonthinae) distributional notes and a new species.

6A4C87E4FF81652E16C947C6FD6E750E.taxon	discussion	Remarks. Compsodactylus mendax new species is easily distinguished from the other four species in the genus because the clypeal apex is enlarged in males while the other species have a trapezoidal clypeus (Fig. 4); the dorsal surface has green metallic reflections and antennae have 10 antennomeres in females, a character combination not found in other species. Compsodactylus mendax is similar to C. martinezi (Frey, 1972) and C. vallejoi Figueroa & Neita-Moreno, 2019 in that all three species have the apical spine of metatibia thick and projecting perpendicular to length of the tibiae in males (Figs. 13 − 18) and females have gonostyles. Compsodactylus argentinus and C. parvulus differ from these three species in that the apical spine of metatibia is thin and projecting parallel to the length of the tibia in males (Figs. 9 − 12) and females do not have gonostyles. Compsodactylus mendax is distinguished from C. martinezi and C. vallejoi by (characters of 1 − C. martinezi and 2 − C. vallejoi given in brackets): dorsal surface with metallic green reflections (1 − as C. mendax; 2 − without green reflections); antennae with 10 antennomeres (1 − nine antennomeres; 2 − as C. mendax: Jhon C. Neita Moreno, personal communication); male protarsomere I greatly enlarged (1 − slightly enlarged; 2 − as C. mendax); male metafemur slightly enlarged and approximately 2.1 − 2.4 times longer than wide (1 and 2 − greatly enlarged and approximately 1.5 − 1.7 times longer than wide; Figs. 13, 15, 17); male metatarsus somewhat filiform (1 − somewhat moniliform; 2 − as C. mendax); male pygidium with hair-like setae (1 − with scale-like setae; 2 − as C. mendax); females with long gonocoxite (Figs. 23 − 25; 1 − wide; 2 − comma-like).	en	Fuhrmann, Juares, Smith, Andrew B.
