and 86-Beira) as separate from Cluster B containing
the majority of the East African OTUs. Dasymys
montanus (C) did not group with other East African
material, emphasizing its distinct cranial features,
especially since it did not even cluster with other
material from the Ruwenzori Mountains (Minunga,
OTU 45) which is found at a lower altitude than
D. i. montanus. Cluster D represents the two
Malawian OTUs (from the Zomba and Mulanje
Plateaux, OTUs 81 and 82), which consistently
grouped with Zambian material in previous figures.

Fig. 6A). The two Ethiopian OTUs (29 and 30)
appeared to be more similar to western African
than to southern African material. South African
OTUs overlapped on the first axis, but separated
on the second axis with the exception of OTU
107 from Mfongosi (KwaZulu-Natal Province,
South Africa), which appeared to be more similar
to Limpopo Province material. Fig. 6B indicated
that D. foxi was similar to material from the other
two Nigerian OTUs representing D. rufulus
(Wilks λ =0.000, p < 0.01). A separation was
seen again within the DRC on the first axis
