Some records in Weber (1986) are misidentifications of Helminthocarpon leprevostii, a species that is very common throughout the Galapagos dry lowlands, but one specimen collected by Pike (ID 37-18) is confirmed here as D. afzelii. This conspicuous species has since not been re-discovered and must be presumed extinct from the archipelago.
