Maxomys hellwaldii (Jentink, 1878) . Notes Leyden Mus., 1:11.
TYPE LOCALITY: Indonesia, Sulawesi, NE peninsula, Menado .
DISTRIBUTION: Throughout Sulawesi in tropical lowland evergreen rain forest (Musser and Holden, 1991).
SYNONYMS: cereus, griseogenys, localis.
COMMENTS: Among Sulawesian representatives of Maxomys, M. hellwaldii is most closely related to M. dollmani (Musser, 1991) . Spermatozoal morphology was unlike species of Malayan Maxomys studied, and more similar to species of Margaretamys, another Sulawesian endemic (Breed and Musser, 1991).
