Castiarina rediviva  Distinctive features

Elytra background yellow with orange margin; ventral side yellow Barker 1990. SA forms being referred to this species here (on this website) have the elytra background all orange.

Notes

SA specimens with an all-orange elytral background are not a good fit for any of the species descriptions given in Barker 1990 for what may be termed 'the Castiarina elderi sub-group' of the C. decemmaculata species group.

They have been placed here under C. rediviva rather than under C. diversa due to their larger size. In Barker's account both those species have the elytral background yellow with orange margin, their ventral side yellow, and have a similar shaped aedeagus, but C. diversa as described is a substantially smaller beetle. If the size difference is shown to be unsupported, then C. rediviva may need to be sunk within C. diversa which is an older name.

Alternatively, the SA orange forms might be considered as a colour variant of C. creta, but that seems less preferable, since C. creta as currently known has a very limited distribution and its definition is also unclear.
