Text Appearing Before Image: 156 Rainer Hutterer et al.: A tiny new species of Sylvisorex from the Bamenda Highlands, Cameroon Text Appearing After Image: Fig. 4. Lower Bambili crater showing relict montane forest on the slopes and montane grassland along the shore of the lake. Photograph taken in 2001. (W. Böhme, field notes). The slopes of the lower Bambili crater are covered by a mosaic of montane forest, La- siosiphon and bamboo woods and grassland. The slopes are partly rocky (Fig. 4). The surroundings of the craters are covered mainly by extensive pastures, Pteridiiim fern growth and open Lasiosiphou woods. It is not known where the owls picked up the shrews but the slope forest and the wet grassland bordering the lake may constitute suitable habitats. Etymology. Derived from silvainis (Latin, meaning for- est god). We dedicate this ciyptic pygmy shrew to the syl- vans, small and invisible forest creatures occurring in the beliefs, mythologies, and fairy tales of Africans, Euro- peans, and many other peoples on earth. As a coinmon name we suggest "Bamenda pygmy shrew". DISCUSSION The forests around Mt. Lefo are still full of mysteries. Dur- ing their field work in 1974, Böhme and Hartvv'ig collect- ed 35 specimens, representing 12 species of shrews and rodents (Table 3). Four of the species were subsequently described as new taxa: Colomys (goslingi) eisentraiiti Di- eterlen, 1983, Lopliiironiys (sikapusi) eisentraiiti Dieteiien, 1979, Hybomys eisentraiiti Van der Straeten & Hutterer, 1986 (tentatively assigned to Hybomys cf badius by MussER & Carletön 2005), and Sylvisorex silvanoriun n. sp. (see Dieterlen 1979, 1983, Van der Straeten & Hutterer 1986). A further species of Sylvisorex still awaits description. Hutterer et al. (1992) proposed full species rank for Lophnromys eisentraiiti, and further but yet unpublished research suggests that Colomys eisentraiiti and Hybomys eisentraiiti inay deserve species status as well. The forests around Mount Lefo (including the Bam- bili craters) apparently house a number of local endemic mammals, some of which may be threatened with extinc- tion. The local Colomys eisentraiiti and Loplniromvs eisen- traiiti have not been found again since their discovery in 1974. At least four mammal species are only known from the Lefo Mountains. 8 from the Bamenda Plateau, and inore than 10 are endemic to the Cameroon Mountains chain (Hutterer et al. 1992). Stager & Anfang-Sutter (1999) provided evidence from lake sediment cores of pro- nounced climatic changes in the West Cameroon High- lands since 24,000 years BP, particularly in the Lake Bam- bili area. It is probable that such climatic fluctuations trig- gered speciation in the Bambili area and other highlands in NW Cameroon (Eisentraut 1973). Acknowledgements.

Eine neue Spitzmausart, Sylvisorex silva- iioruin n. sp., wird nach Material, das am Bambili-Kratersee im Bamenda Hochland Nordwest-Kameruns gesammelt wurde, be- schrieben. Es handelt sich um eine der kleinsten Arten der Gat- tung, die vemiutlich die Schwesterart zu 5. vidcanorum aus Ost- afrika ist. Wie die Nagerarten Colomys eisentraiiti und Lophn- romys eisentraiiti ist die neue Sylvisorex-Art bisher nur aus der Umgebung des Bambili-Kraters bekannt.
