dc.description.abstract |
Based on morphological and morphometric comparisons, a new
species of Hylomyscus, H. arcimontensis (Muridae: Murinae), is identified from
Mount Rungwe and the Eastern Arc Mountains of central and eastern Tanzania.
The new species is confined to wet montane forests of these mountains and
represents another vertebrate endemic to the Tanganyika-Nyasa Montane Forest
biotic region (sensu Moreau 1966). It is most closely related to H. anselli, a
form described from mountains in northern Zambia as a subspecies of H. den-niae
and here elevated to species rank. Morphological evidence supports the
view that the nominal species H. denniae is a composite of several species
whose interrelationships and differentiation patterns indicate two species com-plexes:
the H. denniae group centered in Central East African mountains (Bu-rundi,
Kenya, Rwanda, Uganda, Zaire) and the H. anselli group distributed
across more southern mountains (Angola, Malawi, Tanzania, Zambia). |
