Schlieben’s Triaspis (Triaspis schliebenii)
Schlieben’s Triaspis was described in 1935; it is known only from the type material that was collected somewhere around Lake Lutamba in the Lindi District, Tanzania; it was not found subsequently and is thought to be possibly extinct.
The photo below shows a somewhat similar-looking species, the Blue-leaved Triaspis (Triaspis glaucophyllaEngl.) from southern Africa.
