Three new eriophyid species (Phyllocoptinae), Shevtchenkella denticulata sp. n., Notallus pestehae sp. n. and Echinacrus ruthenicus sp. n., were described from Eryngium thyrsoideum Boiss. (Apiaceae), Pistacia vera L. (Anacardiaceae) and Lycium ruthenicum Murray (Solanaceae), respectively. All the three new species were collected from southwest of the East Azerbaijan province, Iran in 2011. It is the first record of an eriophyoid mite collected from E. thyrsoideum and L. ruthenicum and the first record of Notallus from Anacardiaceae plant family.
East Azerbaijan, Notallus, Echinacrus, Shevtchenkella, Eriophyoidea, washing method
As far as known concerning Iranian fauna, no eriophyoid species has been recorded from Apiaceae. Four eriophyoid species (Aceria mangiferae Sayed, 1946, Aceria pistaciae (Nalepa, 1899), Aceria stefanii (Nalepa, 1898) and Calacarus citrifolii Keifer, 1955) have been recorded from Anacardiaceae (
Considering the relevance of this subject and the scientific importance of the evaluation of the mite fauna in scarcely known areas (
The eriophyoid mite fauna of Eryngium thyrsoideum, Pistacia vera and Lycium ruthenicum was surveyed in the southwest of East Azerbaijan, Iran, during 2011. Mites were recovered from plant materials according to the modified washing method based on the protocol developed by

Holotype: single female on a microscope slide (ET-IEA-AJ11L-1) (deposited at the Acarology Laboratory, Department of Plant Protection, Faculty of Agriculture, University of Tabriz, Tabriz, Iran). Paratypes: 12 females, 1 male and 2 nymphs mounted on separate microscope slides.
Mites preserved in Oudemans’ fluid and extracted from the sample collected in the same locality on the same date above mentioned.
This species is named based on the denticulate shape of the female genital coverflap.
This is the first record of a species belonging to the genus Shevtchenkella collected on a plant of the family Apiaceae and the first record of an eriophyoid mite on Eryngium thyrsoideum.
The new species herein described does not show any similarity with any known Shevtchenkella spp. whereas shows some similarities with Aculus pimpinellae (Liro, 1941) collected from Pimpinella saxifraga L. (Apiaceae) in Hollola, Hatsina, Tavastia australis Natural Province, Finland. Differences between these two species, other than those related to the fact they belong to two different genera, are: the ratio between the prodorsal shield length and the length of sc setae (5.5 in Iranian species versus 2 in Liro’s species); number of dorsal annuli (21–24 in Iranian species versus 28 in Liro’s species); size and shape of the female genital coverflap (15×23 with denticulate rear margin in Iranian species versus 15×16 with smooth margin in Liro’s species).

Holotype: single female on a microscope slide (LR-IEA-II11L-1) (at the Acarology Laboratory, Department of Plant Protection, Faculty of Agriculture, University of Tabriz, Tabriz, Iran). Paratypes: 9 females, 2 males and 1 nymph mounted on separate microscope slides.
Mites preserved in Oudemans’ fluid as extracted from the same sample as the type specimens.
The specific epithet is coming from the host plant name ruthenicum, deleting “m” and adding “s” as suffix.
This is the first record of the genus Echinacrus on plants of family Solanaceae, first record of this genus in Iran and the first record of eriophyoid mites on Lycium ruthenicum.
The new species herein described was compared with all Echinacrus species and similarities along with Echinacrus septemcarinatus (Liro, 1941), collected on Frangula dodonei Ard. (the synonym Rhamnus frangula L. was originally listed by Liro) in Lintula, Isthmus karelicus, Finland, were observed. The empodial rays (4 of the Iranian species versus 5 of Liro’s species), shape, number and density of dorsal microtubercles (denser and more numerous in the Iranian species than those of Liro’s description) and prodorsal shield pattern (22 cells in the Iranian species versus a lower number of cells in part differently arranged) are the main differences between the two species.
