 Type host plant   
 Glycyrrhiza glabra L. (Fabaceae); liquorice.   
 Type locality   
Faculty of Agriculture, Lorestan University, Khorramabad, Lorestan Province, Iran (33° 25' 45.2'' N, 48° 15' 34.5'' E), 1,150 m above sea level, coll. S. Jafari, 19 July 2020.  
 Type material   
Holotype female mounted on a microscope slide (GG-IL-LU19B-1) along with 1 paratype female and 1 paratype nymph. 35 paratype females and 6 paratype males mounted on 9 microscope slides (GG-IL-LU19B -2–10).  
 Relation to the host plant Vagrant on leaves. No apparent damage was observed.   
 Distribution   
 Tetra hajiqanbari Lotfollahi & Jafari sp. nov. is at present recorded only from Lorestan province, Iran. However, liquorice is widely distributed in Iran so future surveys could reveal a wider distribution for this new mite species.   
 Etymology   
The new species is named in memory of Dr. Hamidreza Hajiqanbar (1973–2021) for his outstanding contributions to the systematics of Heterostigmata of Iran.  
 Differential diagnosis   
 The new species is close to Tetra glycyrrhizae Denizhan et al., 2007 found vagrant on flowers and leaves of G. glabra in Kalecik, Türkiye. They are similar in ornamentation of coxae and female genitalia coverflap, empodium rays number, number of dorsal semiannuli, semiannuli between coxae and genital coverflap and empodium rays, length of setae e, f and h1 (Table 1). However, they are different in ventral semiannuli number (50 (41–54) in T. glycyrrhizae and 62 (56–63) in the new species), length of setae sc (32 (30–39) in T. glycyrrhizae and 50 (40–50) in the new species), c2 (18 (15–19) in T. glycyrrhizae and 25 (21–25) in the new species), d (40 (38–49) in T. glycyrrhizae and 63 (52–63) in the new species) and 3a (45 (44–51) in T. glycyrrhizae and 60 (51– 60) in the new species) (Table 1). Setae sc of the new species directed upward divergently, but it is directed to posterior in T. glycyrrhizae. The new species frontal lobe has an acuminate large protuberance under it, while the protuberance is absent in T. glycyrrhizae. Tetra glycyrrhizae has a short median line and without submedian lines, but the new species doesn’t have a median line and with two pairs of submedian lines. In the new species the whole prodorsal shield is covered with a texture of fine or coarse lighter dots, while T. glycyrrhizae has been described without any texture. Microtubercles of T. glycyrrhizae ventral semiannuli are elliptical, but they are spiny in the new species.
