( Coleoptera : Chrysomelidae ) attached at the hind wing, IRAN : South Khorasan Province , Sarbisheh city, Shavakand region ( 32° 38' 34" N , 59° 30' 52" E , 6682 m a.s.l.), 5 July 2020 , coll. M. Kohansal. One larva (ARS-20210131-1c) was collected attached to the leg of an immature lace bug, Monosteria sp. ( Hemiptera : Tingidae ), same data except Khusf city, Rubayat region ( 32° 42' 37" N , 59° 16' 37" E , 6617 m a.s.l.), 25 June 2020 . Four larvae (ARS-20210131-1a, 1b, 1d, 1e) were collected from soil (off host) sampled under willow ( Salix sp. ) and hawthorn ( Haloxylon sp. ) trees, same data except Khusf city, Rubayat region ( 32° 42' 37" N , 59° 16' 37" E , 6617 m a.s.l.), 25 June 2020 . All six specimens had started to feed and were engorged. Two larvae (ARS-20210131-1a–1b) are deposited in the Acarological Collection, Jalal Afshar Zoological Museum ( JAZM ), Department of Plant Protection, Faculty of Agriculture, University of Tehran , Karaj, Iran, two specimens (ARS- 20210131-1c–1d) are deposited in the Acarological Collection, Acarological Society of Iran, Department of Plant Protection, Faculty of Agriculture, University of Tehran , Karaj, Iran and two specimens (ARS-20210131-1e–1f) in the collection of the Department of Plant Protection, College of Agriculture, University of Zabol, Iran ( DPPZ ). Remarks Cicaditrombium lorestanensis was described based on only three specimens collected off host from soil samples, one specimen from Lorestan Province (West of Iran ) and two specimens from South Khorasan Province (East of Iran ). During present study, additional specimens were collected in South Khorasan Province (Rubayat and Shavakand region) from soil samples or ectoparasitic on Chrysolina sp. ( Coleoptera : Chrysomelidae ) and Monosteria sp. ( Hemiptera : Tingidae ). Due to the presence of some specimens of Chrysolina sp. in the containers with material extracted in Berlese funnels, it is possible that some of the engorged larvae left their hosts during extraction. The specimens collected in this study are congruent with respect to the leg setal formula [ one specimen (ARS-20210131-1a) abnormally with three setae on femur II on left side] and measurements ( Table 1 ) with C . lorestanensis given by Noei et al . (2017) . The soil samples were taken from under willow ( Salix sp. ) and hawthorn ( Haloxylon sp. ) trees, on which the hosts of these mites seem to feed.
