Taxonomy.
Microgale cowan: Thomas, 1882,
“Ankafana forest, Eastern Bet- sileo,” Madagascar. Restricted by R. D. E. MacPhee in 1987 to “Ankafina ... 10 km S of Ambohimahasoa and 3 km W of Tsarafidy town, on extreme western margin of eastern rain forest; Fianarantsoa, Fianarantsoa [Province, Madagascar]; 21°12°S, 47°13’E.”
Microgale cowani
and
M. jobihely
are sister taxa.
Microgale cowan
: might contain cryptic taxa, so taxonomy requires reassessment. Monotypic.
Distribution.
N, Central Highlands, E & SE Madagascar.
Descriptive notes.
Head-body 68-87 mm, tail 54-87 mm, ear 12-16 mm, hindfoot 15-19 mm; weight 12-17 g. Tail of Cowan’s Shrew
Tenrec
is generally less than 90% of head-body length. Dorsum is speckled brown; individual hairs have dark gray bases and mix of buff and red-brown tips; venter is gray, with buff wash. Tail is markedly bicolored, dark brown above and sharply demarcated from paler reddish buff below; tail is covered with long scale hairs that partially obscure scales. Hindfeet are brown above and dark gray below. Claws on forefeet are moderately long.
Habitat.
Humid and transitional humid to dry forests, disturbed forest edges, and rice paddies at elevations of 530-2525 m.
Food and Feeding.
Diet of Cowan’s Shrew
Tenrec
contains species of Orthoptera, Coleoptera, Hymenoptera, and Annelida.
Breeding.
Two to three embryos were observed in wild-caught Cowan’s Shrew Tenrecs. Lactating females were found from the end of October to the beginning of December. Females showed improved thermoregulation during pregnancy, and resting metabolic rate was increased significantly throughout pregnancy and lactation.
Activity patterns.
Cowan’s Shrew Tenrecs are terrestrial, but some forelimb characteristics suggest digging behavior.
Movements, Home range and Social organization.
No information.
Status and Conservation.
Classified as Least Concern on The IUCN Red List. Cowan's Shrew
Tenrec
is widely distributed and occurs in some protected areas. Its overall population is presumably large but probably decreasing. It tolerates some habitat modification. It faces no
major
conservation threats.
