Two new species of Aceria (Acariformes: Eriophyoidea) associated with Amaranthaceae in Egypt

Abstract

Two new species of eriophyoid mites inhabiting amaranthaceous plants in Egypt are described and illustrated. Aceria mosalahi sp. nov. heavily induces galls on leaves and stems of Chenopodiastrum murale (L.) S. Fuentes, Uotila & Borsch, while Aceria nudata sp. nov. induces red galls on the stems and leaves of Traganum nudatum Delile. Twenty-two Aceria species are known to inhabit plants of the Amaranthaceae family, and those inducing galls are listed here along with their diagnostic characteristic.

A new species, first record and synonymy of eriophyid mites (Acari, Prostigmata) from Egyptian weeds

“…Tubercles sc on rear shield margin, 14-15 apart, setae sc 9-10, directed to the rear. Sayed (1946), ‡ after Soliman and Abou-Awad (1977), § after Lewandowski et al (2021) Coxigenital area smooth; seta 1b 3-4, 8-9 apart; seta 1a 9-10, 9-10 apart; seta 2a 15-17, 17-18 apart; seta 3a 3, 6-7 apart.

“…Remarks Aceria dioscoridis was originally described by Soliman and Abou-Awad (1977) in Egypt based on adult female. Lewandowski et al 2021 described female, male and immature stages of this mite species under the name Aceria mosalahi Lewandowski & Elsayed inducing galls on the leaves and stems of Chenopodiastrum murale (L.) (=Chenopodium murale L.) (Amaranthaceae)Figure6b, but the host plant is incorrectly identified as shown inLewandowski et al 2021 (page 1400: Figure1a). Pluchea dioscoridis is the correct host plant (Figure6).…”
