Distribution

Iran ( Bagheri & Zarei 2012; Hajizadeh et al. 2013; Beyzavi et al. 2013; Navaei-Bonab et al. 2015; Rahmati et al. 2015).

Remarks

Stigmaeus miandoabiensis was described from Iran by Bagheri & Zarei (2012). Hajizadeh et al. (2013) and Beyzavi et al. (2013) compiled checklists of Iranian prostigmatic mites, which equally included S. miandoabiensis . Later, Navaei-Bonab et al. (2015) and Rahmati et al. (2015) also mentioned this species briefly.

Stigmaeus miandoabiensis is very close to S. planus Kuznetzov, 1978 , but it can be distinguished from the latter by e 2 situated on minute platelets (on striate integument in S. planus ), ag 1 –ag 4 on the same shield (ag 1,2 on one shield and ag 3,4 on another shield in S. planus ), and longer ve.

This species is a new record for Turkish fauna, and its deutonymph was identified for the first time in this study. Generally, the Turkish specimens are similar to the type specimens except for the fact that the anterior and posterior regions of the propodosomal shield are covered with tubercles.
