Differential diagnosis.
This species shares the elytral punctuation shape of
M. arrowi
,
M. foveatus
and
M. cornutus
(
Fig. 91
), however, it can differentiated by the large and rounded punctures of the pronotum (
Figs. 44
,
58
) and from the latter two species by lacking the triangular concavity in the base of the pronotum which characterise the two species.
Habitat and distribution.
This species occupies a small range which extends along the south-western coast of
South Africa
from
Cape
Agulhas in the southeast and up to Saldanha Bay in the northwest (
Fig. 2
). The area is situated within the Southwest Fynbos Bioregion which is considered as the core of Fynbos Biome (
Mucina & Rutherford 2006
). The area is mostly sandstone typified by winter rains and low to very low summer rains.
