Identification
Distinguished from other Macrodactylus by combination of small size (7–10 mm), uniform yellow coloration, and elongate body with long legs. The slender, parallel-sided body shape separates it from more robust scarab beetles. Within its range, M. subspinosus is larger and more robust; other small yellow scarabs in Melolonthinae differ in body proportions or have additional markings.
