Type material

Holotype female and 23 paratype females collected from barberry bushes, Berberis sp., ( Berberidaceae ), Iran: Lorestan province, Nurabad, Barkhordar village , 34° 02′ 43" N, 48° 10′ 54" E, 1810 m a.s.l., 23 September 2017, I. Hasanvand. The holotype female and 21 paratype females are deposited as slide-mounted specimens in CALBS; and two paratype females will be deposited in QM.

Etymology

The species is named in honor of Professor Tetsuo Gotoh (Department of Economics, Faculty of Economics, Ryutsu Keizai University) who kindly provided us some of the literatures of this study.

Remarks

Aegyptobia gotohi resembles A. beglarovi Livschitz & Mitrofanov in having the same legs setal formulae, uncinate tarsal claws and long setae 3a and 4a and also same host plant genus Berberis . However, the new species differs from the latter in: prodorsal ornamentation striated and without cells in A. gotohi versus prodorsal ornamentation with striae and numerous cells in A. beglarovi ; intercoxal area between legs III-IV and ventral plate with striation in the new species instead of smooth in A. beglarovi ; propodosomal setae and setae c 1 - 2 narrowly lanceolate in A. gotohi instead of oblanceolate in A. beglarovi . Our new species also resembles A. kermaniensis Farzan & Asadi in that propodosomal setae narrowly lanceolate and area between setae 3a -4a with striation. But it can be separated by: deeply notched propodosomal projection, long setae 3a and 4a (68–78) and ventral plate with longitudinal striae in new species instead of weakly notched projection, short setae 3a and 4a (21–33) and ventral plate with transverse striae in A. kermaniensis . The new species is also closely similar to A. khanjanii Farzan & Asadi, 2015 in leg chaetotaxy, deeply notched propodosomal projection, long setae 3a and 4a and propodosomal setae narrowly lanceolate. However, it can be distinguished from the latter throughout ventral plate with striation (smooth in A. khanjanii ), prodorsum laterally with coarse broken, longitudinal to oblique striae (with several cells in A. khanjanii ) and opisthosomal setae c 1 - 2 narrowly lanceolate in A. gotohi (oblanceolate in A. khanjanii ).
