Comments.
One of the new records provides the first known host plant for the genus,
Grewia flavescens
(
Malvaceae
), where
C. striatus
was collected from fruits of this plant. Presumably older fruits were used as they dry out on the branch and provide a more suitable texture for tunneling. Reproduction was likely successful based on the many specimens collected, unless some kind of maturation feeding occurs.
Several of the new records from Limpopo, KwaZulu-Natal, and the Eastern Cape, extend its known distribution beyond past records from
Namibia
and
Gauteng
in northern parts of
South Africa
(
Schedl 1982
). Apparently, this species is more common than previously reported (
Wood & Bright 1992
). A primary source for the record from
Mozambique
(
Bright & Skidmore 1997
) is not documented. However, it is likely to be found there as this country is located between countries with verified records. The sample from
Namibia
reported by
Schedl (1982)
was not noted as such by
Wood & Bright (1992)
.
