Taxonomy. Crocidura jouvenetae Heim de Balsac, 1958 View in CoL ,
Ziéla, Mount Nimba, Guin- ea.
Crocidurajouvenetae has been recognized as a subspecies of C. crossei , but they have re- cently been recognized as two distinct spe- cies. Genetic data have recently indicated that C. jouvenetae is in a clade including C. crossei (which it was paraphyletic with), C. crenata , C. fuscomurina , and C. lusitania , and this clade was sister to a clade includ-
ing C. cyanea , C. mariquensis , C. silacea , C. hildegardeae , C. batesi , C. foxi , C. buettikofen, C. theresae , C. grandiceps , and C. wimmeri , although more extensive genetic studies are needed. Because C. crossei and C. jouvenetae seem to be paraphyletic, they might still be conspecific, although additional research is needed. Monotypic.
Distribution. S Guinea, Liberia, and Ivory Coast; distribution might be more extensive because distributional limits between this species and Crosse’s White-toothed Shrew (C. crosser) are still uncertain. View Figure
Descriptive notes. Head-body 64-86 mm,tail 47-63 mm, ear 9-10 mm, hindfoot 13-14-5 mm; weight 7-5-12 g. Jouvenet’s White-toothed Shrew is medium-sized, with short
dense pelage. Dorsal pelage is grayish brown, and venter is paler, with no clear delineation between the two. Fur is paler under chin, and upper part of face is dark gray to black, and lower partis silvery with clear demarcation. Ears are large, and feet are pale. Tail is ¢.66% of head-body length, thick but thicker around base, hairy and covered with scattered longer bristle hairs, and bicolored, being grayish brown above and lighter below. There are three unicuspids. Chromosomal complement has 2n = 44 and FN = 66.
Habitat. Mostly primary and secondary lowland forests and cocoa and coffee plantations surrounded by forest. Jouvenet’s White-toothed Shrews have also been found in moist rainforest near coastal lagoons and savannas.
Food and Feeding. Based on stomach samples from Tai Forest National Park, Jouvenet’s White-toothed Shrews largely eat ants; they also eat spiders, millipedes, adult beetles, cockroaches, crickets, larval lepidopterans, mantises, adult flies, and isopods.
Breeding. No information.
Activity patterns. No information.
Movements, Home range and Social organization. No information.
Status and Conservation. Classified as Least Concern on The IUCN Red List. Although Jouvenet’s White-toothed Shrew has a relatively small and scattered distribution, is considered very common where it is found, and makes up 10-25% of shrews captured throughout various regions.
