Differential diagnosis.
Due to it is flatter elytra (
Fig. 74
)
M. mutilans
resembles
M. bias
and
M. fornicatus
, nevertheless, it can be easily distinguished from them by impunctate lateral border of pronotum as well as distinct differences in the shape of the internal sac sclerite (
Fig. 34
).
Habitat and distribution.
This species was collected from localities confined to the Namaqualand region (
Fig. 2
). The area is part from the Succulent Karoo ecoregion which comprises two main bio-geographical domains: The Southern Karoo domain which is inland in
South Africa
and Namaquland—Namibia domain which stretches from the west cost of
Namibia
to the west coast of
South Africa
and includes the areas of Richtersveld, Sandveld, Hardveld and Kamiesberg. The area is semi desert, characterised by a succulent vegetation and winter rainfall.
