The Jenkins white-toothed shrew ( Crocidura jenkinsi ) is a rare, little-researched species of shrew from the genus of the white-toothed shrew (Crocidura). It is endemic to South Andaman Island in the Andaman Islands . The art epithet honors the British mammal login and shrew expert Paulina D. Jenkins from the Natural History Museum in London .

features

The head-torso length of seven measured specimens is 100 to 107 mm, the tail length 92 to 96 mm and the hind foot length 23 to 26 mm. No specific data are available on weight. The gray to nut brown back fur is almost bristly and has 7 to 9 mm long hair. The underside is lighter gray-brown with slightly less bristly fur hair on the belly and on the flanks. The tail is brown and its length is 89 to 96 percent of the head-trunk length. It has sparse, long bristle hairs on the basal half of its length. The feet are brown.

Systematics

The Jenkins white-toothed shrew was described in 1978 as a separate species , Sujit Chakraborty . In 1992 it was synonymous with the Nicobar white-toothed shrew ( Crocidura nicobarica ) by Gordon Barclay Corbet and John Edwards Hill without comment . In 1993 it was given species status again by Rainer Hutterer .

distribution

The terra typica is located at Wright Myo on South Andaman Island. Another deposit was discovered at neighboring Mount Harriet . The known total area of ​​the distribution area is 78 km².

Habitat and way of life

The Jenkins white-toothed shrew is a nocturnal or crepuscular species that occasionally digs passages. It lives in the leaf litter of primary, tropical, humid deciduous forests at altitudes of 100 to 383 m. A single adult specimen was collected from the Mount Harriet National Park Forest Guest House. Nothing is known about their feeding and reproductive behavior. Among the possible seizure free ends include snakes , the Andaman scops owl ( Otus balli ) and the Andaman subspecies of larvae Rollers ( Paguma larvata tyttleri ).

Threat and protection

For a long time, the Jenkins white-toothed shrew was only known from the holotype collected in 1972, until Indraneil Das was able to detect six more specimens on Mount Harriet between August and September 1997. The IUCN classifies the species as " critically endangered ". The main threat is considered to be habitat loss due to selective deforestation, general anthropogenic activities and natural disasters such as the tsunami event in December 2004 .
