Erythraeus larvae are divided into two subgenera on the basis of the ASens which inserted in sclerotized and angled socket which in Zaracarus and without sclerotized and angled socket in Erythraeus (Xu et al. 2019). There are 28 larval species of Zaracarus which are distributed in different countries of Asia (Indonesia, Iran, Pakistan, China), Europe (Bosnia and Hercegovina, Bulgaria, Croatia, Greece, Hungary, Montenegro, Turkey, Poland, Spain, Italy, Ukraine, Cyprus) and Africa (Ethiopia), There is not any record of this subgenus from Nearctic, Neotropical and Australian regions. Among them, E. (Z.) budapestensis Fain & Ripka, 1998 [syns.: E. (Z.) hamedanicus Khanjani, Mirmoayedi, Nahad & Fayaz, 2010; E. (Z.) preciosus Goldarazena & Zhang, 1998; were collected from 10 countries (Mąkol and Wohltmann 2012, 2013; Xu et al. 2019). Erythraeus (Zaracarus) lancifer was described based on larvae ectoparasitic on undetermined fly (Diptera: Dolichopodidae) from Ruerta de Pina, Pina, Zaragoza Province, Spain (Southcott 1995). In this paper, two specimens of the species were collected as ectoparasites of unknown species of Tetramorium (Hym.: Formicidae) in Mahneshan city, Zanjan province and additional biometric data are provided. The family Formicidae is recorded as a new host taxon for this subgenus. Two larvae (ARS–20211215–1a and 1b) ectoparasitic on unknown species of Tetramorium (Hym.: Formicidae) were collected on 5 August 2018 in Anguran Protected Area (36° 33΄ 08.41΄΄ N, 47° 36΄ 44.93΄΄ E, 5283 m a.s.l.), Mahneshan city, Zanjan province. Mites were detached and preserved in 75% ethanol and cleared in Nesbitt’s fluid and mounted using Faure liquid (Walter and Krantz, 2009). Measurements (given in micrometers) were made using BX–51 Olympus microscope equipped with a drawing tube and magnification changer. The terminology and abbreviations follow Wohltmann et al. (2006) and Saboori et al. (2009). They are deposited in the Acarological Collection, Jalal Afshar Zoological Museum, Faculty of Agriculture, University of Tehran, Karaj, Iran. https://www.persianacarology.org/article_238551_e41b4620f872ebf9e48392ca88d6757c.pdf
