Differential diagnosis.
This species differs from all
Macroderes
species except
M. cornutus
in that the base of the pronotum bears very deep triangular concavity (
Figs. 8
,
40
) however, it can be separated by the combination of the following characteristics: lack of the rounded tubercle in the frontal suture that characterises
M. cornutus
(
Figs. 49, 51
), the internal sac sclerite bears small lateral processes (
Fig. 31
), less elongated punctures at each side of the pronotum (
Fig. 46
).

Habitat and distribution.
This species is recorded from two localities in the southern western part of
Western Cape Province
along the west coast of
South Africa
(
Fig. 2
). Generally, the area is characterised by Mediterranean climate with warm, dry summers and moderate humid, rainy winters (
Mucina & Rutherford 2006
).
