Lengths of palpalae: dF about 30, dG about 15, l”G about 7. Idiosoma 165 long (165–175), its striated cuticle dorsally covered by microscales. Propodonotal shield 110 long (110–115) and 130 wide (130–140). Posterior part of propodonotal shield without ornamentation. Distinct U-shaped striae immediately anterior to setae ag absent. Setae f1, f2, h1, and h2 and most of dorsal idiosomal setae distinctly serrate, except smooth e1 and e2. Setae h2 situated distinctly posterior to level of setal bases h1. Lengths of idiosomal setae: vi, ve, si, and d1 48–55, c2 55 (55–60), e1 44 (43–46), e2 45 (45–49), f1 56 (53–58), f2 49 (49–54), h1 50 (50–60), and h2 53 (52–55). Femur I with 3 setae (d, v’, and v” present), femur II with 2 setae (v’, and v” present). Setae dF I, dTr III, dTrI V, vTr III, and vTr IV moderately serrate, vF III, and vF IV slightly serrate. Setae vTr III and vTr IV subequal to setae vF III and vF IV, respectively.

MALE (1 paratype, Fig. 13 A). Body190 long and 160 wide. Gnathosoma 45 long. Palp femur-genu 32 long. Lengths of palpalae: dF 23, dG 8, l”G 14. Idiosoma 145 long, its striated cuticle dorsally covered by microscales. Propodonotal shield 120 long and about 125 wide. Setae vi situated posterior to ve, distance between levels of setal bases vi and ve 13. Distance vi– vi 45, ve–ve 23. Setae si, d1, and e2 smooth, c2, f1, h1, and h2 serrate. Distance between levels of setal bases e1 and g1 10, between g1 and g2 7. Lengths of idiosomal setae: si 15, d1 20, e2 14, c2 37, f1, h1, and h2 45–50. Genital opening situated at level of setal bases d1. Leg setation as in female.

Type material. Female holotype ( OSAL 0082946), 8 female (0082948–0082955) and 1 male ( OSAL 0082947) paratypes from Fringilla coelebs Linnaeus (Fringillidae) , THE NETHERLANDS: Gelderland, Arnhem, 51.98°N 5.92°E (GEOnet), 14 February 1976, coll. F. S. Lukoschus.

Non-type material. Six females and 3 males ( ZISP AVB 07-2001-002) from Fringilla montifringilla Linnaeus (Fringillidae) , KAZAKHSTAN: Ongtustik Qazaqstan, Chokpak Ornithological Station, 1134 m, 42°30'45.2''N 70°35'46.2''E, 13 October 2007, coll. P.B. Klimov.

Holotype deposition. OSAL.

Etymology. This species is dedicated to the well known acarologist Dr. D. E. Johnston ( USA).

Differential diagnosis. This species is closely related to H. regulus sp. nov. In both these species, the dorsoidiosomal striae bear scales and in females, setae d1 are smooth. H. johnstoni sp. nov. differs from H. regulus sp. nov. by the following features. In females of H. johnstoni , setae h2 are situated distinctly posterior to setal bases h1, setae vTr III and vTr IV are subequal to setae vF III and vF IV, respectively; in males, distance ve–ve is almost 2 times longer than vi–vi, and the genital opening is situated at the level of setal bases d1. In females of H. regulus , setae h2 are situated slightly anterior to setal bases h1, setae vTr III and vTr IV are two times longer than setae vF III and vF IV, respectively; in males, distances vi–vi and ve–ve are subequal, and the genital opening is situated anterior to setal bases d1.
