Crocidura roosevelti View in CoL
French: Crocidure de Roosevelt / German: Roosevelt-WeilRzahnspitzmaus / Spanish: Musarana de Roosevelt
Other common names: Roosevelts Shrew
Taxonomy. Heliosorex roosevelti Heller, 1910 ,
Rhino Camp , Lado Enclave , Uganda .
Crocidura roosevelti is the type species of subgenus Heliosorex, named by E. Heller in 1910. According to genetic studies by S. Quérouil and others in 2005, it does not cluster with C. dolichura and C. crenata as suggested by R. Hutterer in 1981 and 1994. In a recent phylogenetic study by S
Dubey and colleagues in 2008,it is closely related to West Palearctic C. russalaEe C. pachyura and in a basal position to all other Afrotropical Crocidurines. Monotypic.
Distribution. Forest-savanna margin of the African forest block; there are records from Cameroon, Central African Republic, DR Congo, Uganda, Rwanda, Tanzania, and NE Angola, and possibly present in South Sudan. View Figure
Descriptive notes. Head-body 62-82 mm, tail 59-69 mm, ear 6 mm, hindfoot 14-15 mm; weight 9 g. Condylo-incisive lengths are 20-7-22 mm. Roosevelt's Whitetoothed Shrew is small and pale cinnamon-brown, with tail 85-96% of head-body length. It is similar to the Somali White-toothed Shrew ( C. somalica ), except it has a more reddish hue and longertail, which is bicolored and nearly naked. Dorsal pelage is grayish brown, with gray-based hairs and cinnamon-brown tips. Ventral pelage is whitish gray, with gray-based hairs and white tips. Head is similar to dorsal color. Ears are relatively large. Forefeet and hindfeet are flesh-colored, with whitish hairs. Soles of hindfeet have granulae between plantar pads. Tail is distinctly bicolored, being cinnamon-brown above and white below. Tail has only a few short bristle hairs and appears naked (pilosity of short hairs ¢.70%). Tails of Angola specimens are 86-94% of head-body length. Skull is elongated and gracile. Interorbital region is narrow and almost parallel. Braincase is slightly arched, and dentition is weak. I' is moderately long and hooked. M? is narrow to medium-sized.
Habitat. Moist savanna around the Congo Basin forest block. Roosevelt's Whitetoothed Shrew inhabits lowlands at elevations below 1200 m. In Rwenzori National Park, specimens were found in Imperata-Cymbopogon grass and Capparis-Euphorbia bushland mosaic.
Food and Feeding. No information.
Breeding. No information.
Activity patterns. No information.
Movements, Home range and Social organization. Roosevelt’s White-toothed Shrews are occasionally found in pellets of common barn owls (7yto alba) in Garamba Na- tional Park, DR Congo (five of 172 shrews from 13 species).
Status and Conservation. Classified as Least Concern on The IUCN Red List. Roosevelt's White-toothed Shrew is widespread, and it does not appear to face major threats. It is found in Queen Elizabeth National Park in Uganda and Garamba National Park in north-eastern DR Congo.
