Lesser Black-footed White-toothed Shrew
French: Crocidure lionne / German: Kleine SchwarzfuR-\ Weil3zahnspitzmaus / Spanish: Musarana de pies negros menor
Other common names: Sulawesi Shrew
Taxonomy. Crocidura lea G. S. Miller & Hollister, 1921 View in CoL ,
Temboan , Sulawesi, Indonesia.
Crocidura lea is part of the strongly supported “Old Sulawesian” clade of shrews that evolved from an ancient (Miocene) colonization from the Sunda Shelf to the island of Sulawesi. Other shrews of this ‘ os:: ancient radiation include the Sulawesian endemics C. mussen, C. levicula , C. rhoditis , and C. elongata but not C. nigripes (evolved
from a more recent colonization event). Crocidura lea occurs in sympatry with other insectivorous mammals, including Sulawesian endemic shrews ( C. musseri , C. rhoditis , C. nigripes , and C. elongata ) and several murid rodents (7aeromys spp. and Melasmothrix spp-). Monotypic.
Distribution. Endemic to N & C Sulawesi; its absence from S peninsulas of Sulawesi should be ascertained with adequate surveys. View Figure
Descriptive notes. Head-body 61-64 mm, tail 53-56 mm, hindfoot 12-1-12-8 mm; weight 4-6-5-5 g. The Lesser Black-footed White-toothed Shrew is small, dark brown dorsally, and slightly larger than the sympatric Sulawesi Tiny White-toothed Shrew ( C. levicula ). Venter of the Lesser Black-footed White-toothed Shrew is slightly lighter grayish brown. Tail is 80-90% of head-body length, with numerous long bristle hairs extending along proximal two-thirds. Face, ears, and feet are dark brown. Compared with other Sulawesian species of shrews,first hook-like incisor is particularly small. In maxillary tooth row, second unicuspidate tooth is smaller than third.
Habitat. Lowland evergreen rainforests to moss forests covering highest summits from near sea level to elevations of ¢.2300 m. The Lesser Black-footed White-toothed Shrew is found in primary and secondary forests among leaf litter or on moss-covered vegetation.
Food and Feeding. The Lesser Black-footed White-toothed Shrew eats invertebrates, but no precise data are available.
Breeding. One pregnant Lesser Black-footed White-toothed Shrew caught in August carried two embryos.
Activity patterns. The Lesser Black-footed White-toothed Shrew is terrestrial and apparently mainly nocturnal.
Movements, Home range and Social organization. No information.
Status and Conservation. Classified as Least concern on The IUCN Red List. The Lesser Black-footed White-toothed Shrew is widespread on Sulawesi, and its overall population is presumably large. Its tolerance to anthropogenic impacts to its habitat is unknown. It is locally common based on pitfall trapping and occurs in protected areas such as Lore Lindu National Park.
