acorns from Lithocarpus, but it ignored adult forms of the
beetle larvae, trap bait, carabid beetles, lizards, and earth-
worms. Both species of acorns (Lithocarpus celebicus and
Lithocarpus glutinosus) were accepted, but L. glutinosus ap-
peared to be favored. Its diet is assumed to be arthropods
and fruits, with acorns and fi gs preferred. H. ileile forages in
the leaf litter. Females have three pairs of teats: two inguinal
pairs and one abdominal pair.

This genus comprises four species of striped ground squir-
rels from Indonesia.
Lariscus hosei (Thomas, 1892)
Four-Striped Ground Squirrel
description: This species is distinguished by a brown
mid-dorsal stripe and an orange brown venter.
size: Female—HB 189.0 mm (n = 2); T 86.0 mm (n = 2); Mass
215.0 g (n = 1).
Sex not stated—HB 181.0 mm (n = 2); T 126.0 mm (n = 2).
distribution: L. hosei is found in the northeastern portion
of the island of Borneo (Sabah and Sarawak [Malaysia] and
Ea s t K a l i ma nt a n [ Indonesia]), at elevat ions a s h ig h a s 1530 m
on Mount Kinabalu (Sabah, Malaysia).
geographic variation: None.
conservation: IUCN status—near threatened. Population
trend—decreasing.
habitat: L. hosei depends on primary forests in the island
of Borneo; these are being deforested for timber at a rapid
pace, which threatens its survival.
natural history: This species is extremely rare, and no
information has been published on its natural history.
