Diagnosis
editThe only known remains of this species is a subfossil right dentary from an adult collected in 1969. The dentary is mostly undamaged except for the missing tip of the coronoid process. The type locality of the species is Leang Burung 1, a cave near the village of Pakalu. Remains from the cave have been dated at 2820 ± 210 (2,360–3,460) BP, indicating that Lenomys grovesi lived as recently as 3,000–2,000 years ago.
Description
editLenomys grovesi was smaller than the living trefoil-toothed giant rat (Lenomys meyeri), assuming the size of the dentary and molars reflect overall physical size of these rodents. No known subfossil or living examples of the trefoil-toothed giant rat match the dimensions of L. grovesi, so it can be assumed that the species is distinct.
Distribution and habitat
editIt is only known from the Maros karst region in southwestern Sulawesi. The environment that L. grovesi would have lived in at the time was probably a mosaic of primary forest, expanses of secondary forest, and possibly more open habitats.
