Phylogeography and Conservation of the Rare South African Fruit Chafer Ichnestoma stobbiai (Coleoptera: Scarabaeidae)

Abstract

Ichnestoma stobbiai is an endangered fruit chafer (Scarabaeidae: Cetoniinae) that occurs in small habitat fragments of South Africa. The adults of this species are short-lived and the females are flightless. Thus, the vagility of these beetles is extremely low. Prompted by the recent discovery of morphological diver-gence between geographic populations, this genetic study aimed to assess genetic differentiation within and among these different populations. DNA sequencing of the cytochrome c oxidase subunit 1 mitochondrial gene was used to determine the genetic composition of the populations. Most populations revealed low haplotype diversity. Phylogenetic analysis of the sequence data resulted in a basal polytomy. Nested clade analysis inferred allopatric fragmentation for all significant clades. This reconfirms the original hypothesis that the extant populations represent relicts of a single, formerly widely distributed species. All habitat patches should be protected and a detailed plan for genetic augmentation should be worked out.
