A new species of flat mite, Cenopalpus umbellatus sp. nov. (Acari: Trombidiformes: Tenuipalpidae) is described and illustrated based on females, males, deutonymphs, protonymphs and larvae. The morphological ontogeny in idiosomal and leg chaetotaxy is briefly described for all stages. Mite specimens were collected from the leaves of Rhaphiolepis indica var. umbellata Makino (Rosaceae), an evergreen shrub native to Japan. An identification key to the world species of Cenopalpus is also provided.

“…It was detected on three samples collected in March and April 2015 in the Western Cape Province. It was found in association with Brevipalpus lewisi, B. obovatus (Trombidiformes: Tenuipalpidae) (Saccaggi et al 2017) and Colomerus cf. vitis (Trombidiformes: Eriophyidae), on which it is assumed to be feeding.…”

“…Plant samples were collected from grapevine (Vitis vinifera, various cultivars) throughout South Africa as part of a nation-wide survey from March 2015 -November 2016 (for more details see Saccaggi et al 2017). Shoots and leaves from each plant were collected, sealed in plastic bags, and transported to the laboratory for microscopic inspection.…”

“…In 2015 South African authorities detected a newly introduced pest of quarantine status on grapevine, Brevipalpus lewisi (Trombidiformes: Tenuipalpidae) (Saccaggi et al 2017). During the delimiting survey that followed this detection, a non-native predator, Agistemus collyerae (Trombidiformes: Stigmaeidae) was found on some samples around the same location where B. lewisi was first detected.…”

Agistemus collyerae (Acari: Trombidiformes: Stigmaeidae) in South Africa: first record, introduction pathways and a re-description including additional life stages

Agistemus collyerae Gonzáles-Rodrigues (Stigmaeidae) is reported for the first time in South Africa on grapevines in the Western Cape Province. We investigate a possible introduction pathway of this mite as a contaminant on imported agricultural goods. Based on South African interception data, we report new country records of A. collyerae in the USA, Chile, Yemen, Spain and France. We re-describe it based on the South African specimens, including first-time descriptions of the male and deutonymph. Female specimens have shorter dorsal setae than those documented in the original descriptions, but we do not consider this enough evidence to justify a new species.

“…Brevipalpus lewisi is a new grapevine pest in the Western Cape (Saccaggi & Ueckermann, 2018). At present it is unclear what its predators are (Saccaggi et al, 2017) and if T. spicieae could potentially be preying on B. lewisi.…”

An Overview of Mites on Grapevine and the Discovery of a new Phytoseiidae Species; Typhlodromus (Typhlodromus) spiceae

The European grapevine (Vitis vinifera L.) is the main species used for wine making, with South Africa being one of the top wine exporting countries. Grapevine is vulnerable to a range of pests, including mites. We present an overview of phytophagous and predatory mites on grapevine in South Africa and describe a new phytoseiid species which was discovered in the winelands region of Wellington, South Africa. Grapevine shoots with leaves were collected over two growing seasons at four farms in Wellington. A nursery, mother block and a commercial vineyard were selected on each farm. The mites were removed with a mite brushing machine and slide mounted. The Phytoseiidae Database, as well the most recent relevant literature were used in confirming the new species. Illustrations of the new species were made using photographs taken by Zeiss Axioskop TM Research that included a Zen Soft Imaging System. The new Typhlodromus species, Typhlodromus (Typhlodromus) spiceae sp.n., is set apart from closely related species by setae Z4 being 0.7 times the length of Z5 and by having a short, saccular and thick-walled spermathecal. This species was found together with one phytophagous mite species (Brevipalpus lewisi) and several predatory mite species (Typhlodromus praeacutus, Typhlodromus saevus, Eusieus addoensis). A key to identify females of the South African species of Typhlodromus (Typhlodromus) is provided.
