Ceroctis korana
species group
The validity of this heterogeneous assemblage, based only on phenetic similarities, needs confirmation. It is apparently endemic to the southwestern Africa.

Remarks.
Types
of this species were examined at MNHN.
The taxonomy of this species was discussed by
Bologna (2000a)
, who synonymized the
ssp.
rudebecki
Kaszab, 1956
with the nominate form.
The phylogenetic position of
C. amphibia
is unclear, but we suggest possible relationships with
C. korana
and
C. karrooensis
,
due to the common shape of the wide pronotum with similar puncturation, and the similar shape of antennomeres. Actually,
C. amphibia
is well distinct from the remaining species at least because of the partial red colour of femours.

Remarks.
Types
of this species were examined at SAMC.
The elytral pattern is variable, due to the extension of the black colouration. Orange-yellow spots are usually estended and partially coalescent, forming transverse irregular fasciae. Small and round spots without fasciae are present in few specimens (E of Windhoek, Diamond Area, Boom River; South Africa, Richtersveld), which appear distinct from the most common phenotype. Male antenna, pronotum and male genitalia are illustrated in

Remarks.
Types
of this species were examined at SAMC.
This species is similar to
C. karrooensis
, but distinct because of the following characters: shiny integuments, deeper and more distanced punctures of head and pronotum, male antennomeres IV–IX less serrate, wider extension of lemon yellow colouration, particularly on the fore fascia.
We suspect that
C. gariepina
(Péringuey, 1888)
from northwestern South Africa could represent only an elytral variation of
C. korana
.
