“…Anchonocranus oleae is part of the rich assemblage of native sub-Saharan African insects associated with wild and cultivated olive trees and fruits. Part of the diversity of parasitoid, hyperparasitoid and seed wasps, olive fruit flies, and olive lace bugs found in South Africa has been recently characterized at the DNA sequence level, either with complete mitogenomes [ 10 , 11 ], DNA barcodes [ 64 ], or other genetic data that have allowed for new insights into the diversity and lifestyles of olive insects [ 12 ]. This work further contributes to the genetic cataloguing of the entomofauna of O. europaea in southern Africa.…”

“…pallida [sic] [ 7 ], but the pale colour for which it was named may only be due to a teneral state. If A. oleae pallidus is indeed only a form (or subspecies) of A. oleae from South Africa, the geographical distribution of A. oleae seems to concord with that of the African Wild Olive, as is the case with other insects associated with Oleaceae in sub-Saharan Africa, including several species of olive fruit flies, olive lace bugs, and olive flea beetles and a diversity of parasitoid, hyperparasitoid, and olive seed wasps [ 8 , 9 , 10 , 11 , 12 , 13 ]. However, general surveys of insects in the fruits of Oleaceae in Kenya [ 8 ] and the African Wild Olive in South Africa [ 3 , 9 ] did not detect the presence of A. oleae , and it was only recently again reported from fruits of the African Wild Olive in the Western Cape and Eastern Cape provinces of South Africa, at a very low frequency [ 14 ].…”

Anchonocranus oleae Marshall (Coleoptera: Curculionidae) is a seed-feeding weevil native to southern Africa; its larvae are known to develop in the fruits of the African Wild Olive and, more rarely, cultivated olives. The species has been mainly found in the Western Cape province of South Africa, but it has remained in relative obscurity because it does not seem to represent a current threat to commercial olive production. As part of an ongoing effort to produce baseline genetic data for olive-associated entomofauna in South Africa, we generated reference DNA barcodes for A. oleae collected from wild and cultivated olives and sequenced its mitogenome for assessment of the phylogenetic position of the species in the family Curculionidae. The mitochondrial phylogeny estimate indicated that A. oleae shares a common ancestor with Elaidobius (tribe Derelomini), but a definite and close relationship to this tribe and the precise tribal placement of A. oleae in the subfamily Curculioninae could not be inferred due to the lack of representative mitogenomes of other relevant curculionine tribes and genera. This study will assist future work on the DNA-based species identification, genetic diversity, and phylogenetic position of the genus Anchonocranus and related taxa.

Olive lace bugs (Hemiptera: Tingidae) are small sap-sucking insects that feed on wild and cultivated Olea europaea. The diversity of olive lace bug species in South Africa, the most important olive producer on the continent, has been incompletely surveyed. Adult specimens were collected in the Western Cape province for morphological and DNA-based species identification, and sequencing of complete mitogenomes. Cysteochila lineata, Plerochila australis, Neoplerochila paliatseasi and Neoplerochila sp. were found at 12 sites. Intra- and interspecific genetic divergences and phylogenetic clustering in 30 species in 18 genera of Tingidae using new and publicly available DNA barcodes showed high levels of congruity between taxonomic and genetic data. The phylogenetic position of the four species found in South Africa was inferred using new and available mitogenomes of Tingidae. Notably, olive lace bugs formed a cluster of closely related species. However, Cysteochila was non-monophyletic as C. lineata was recovered as a sister species to P. australis whereas Cysteochila chiniana, the other representative of the genus, was grouped with Trachypeplus jacobsoni and Tingis cardui in a different cluster. This result suggests that feeding on O. europaea may have a common origin in Tingidae and warrants future research on potential evolutionary adaptations of olive lace bugs to this plant host.
