specimens of an undescribed species
+Australia, *South Africa
- dark red in colour
- dorsal body setae thick, barbed, blunt distally
- prodorsum with median area of punctate cuticle incorporating setae v2 and sc1
- opisthosoma with strong, thick, transverse striae
- dorsal setae set on punctate tubercles
- peritreme emergent, ending in ovate, anastomosing expansion
Citrus limon, *C. sinensis (Rutaceae), Prunus persicae (Rosaceae)
Females lay many eggs over the bark of the host navel orange trees, Citrus sinensis (Rutaceae). Females of A. citri were collected with A. honiballi in the Caper Province of South Africa. In Australia, A. citri has been collected from Prunus persicae (Rosaceae) and Citris limon (Rutaceae).

In 1910, Berlese described Tetranychopsis histricina from fruit trees in NSW, collected by Froggatt. Then Womersley (1940) described a new genus and species Aplonobia oxalis from Oxalis in South Australia and from peach trees in NSW. Womersley indicated that his species was similar to another species that had been recorded on fruit trees in Australia by Froggatt, Tetranychopsis histricina Berlese 1910.
Pritchard and Baker (1955) introduced a new combination, redescribed the troublesome Aplonobia histricina (Berlese) and made Aplonobia oxalis a synonym of Aplonobia histricina. However, Gutierrez and Schica (1983) examined some of Womersley's original material and felt that the specimens from Oxalis were A. histricina, but the specimens from peach were in fact A. citri Meyer-Smith. Gutierrez and Schica (1983) believe that both species occur in Australia, but a detailed revision of the genus is needed to confirm this.
