Heterotergum zaheri (Acari: Eriophyidae), New Species From Egypt and A New Eriophyoid Record

Abstract

During the survey of eriophyoid mite fauna from Qalyubia and Giza governorates in Egypt from 2012 to 2017. A new eriophyoid mite species, Heterotergum zaheri sp. nov. was collected from Ziziphus spina–christi (L.) Desf (Rhamnaceae). It was described and illustrated. This mite is vagrant in the tender apical shoots (between hairs) and on the lower surface of young leaves. It causes no apparent damage. This is the second species in genus Heterotergum has been recorded in Egypt. A supplementary descriptions of two eriophyoid species Vittacus bougainvilleae (Keifer, 1959) comb. nov. (transferred from Phyllocoptes), was recorded for the first time in Egypt, infesting Bougainvillea glabra Choisy (Nyctaginaceae). Aculops guajavae Abou-Awad, Al-Azzazy & Afia, 2016 was assigned a senior synonym of Tegolophus guavae (Boczek, 1960) from Psidium guajava L. (Myrtaceae) which causes rust on terminal leaves, based on the presence of strong frontal lobe, opisthosoma with 3 ridges, middorsal ridge stronger than lateral ridges.
