( Figs. 39–41 )

Diagnosis. FEMALE ( Fig. 39 ). Subcapitular setae m with 3 tines. Most dorsal setae of idiosoma wide lanceolate. Setae vi distinctly wider than e2. Setae e1 and f1 filiform. Distance c1-d1 1.5 times longer than d1-d2. Vulvar region ornamented in posterior part. Setae ps3 distinctly developed, slightly curved. Setae ag2 broken. Setae 1b and 1d slightly thicker than 1a. Setae 2a whip-like, much longer than 2b. Setae 3a short, subequal 4a. Trochanter I with ventral projection, without tubercles. Measurements of holotype: body, including gnathosoma, 430 long, 185 maximum wide. Lengths of setae: vi 80 (7 wide); ve 125, si 115, se 110, c2 115—all 12 wide; c1 85, d1 80, d2 87— all 15 wide; e1 and f1 about 10, e2 37 (4 wide), 2a 65, 3a and 4a about 12.

MALE ( Fig. 40 ). Subcapitular setae m membranous lanceolate, pointed apically. Genital cone slightly elongated, length/width ratio 1.7–1.8:1, with straight lateral margins without projections. Bases of setae vi situated anterior to setae ps2. Setae f1 and e2 very short, more than 5 times shorter than e1, f1 about 2 times shorter than e2. Posterior end of opisthosoma with few tubercles. Setae 2a very short, setae 2b subequal to 3a and only slightly longer than 4a. Trochanter I with weakly developed ventral projection, without tubercles. Dorsal seta of trochanter III shorter than respective segment. Measurements of paratypes: body, including gnathosoma, 300–310 long, 180–185 maximum wide. Aedeagus 125 long. Lengths of setae: vi 15–17, ve 55–57, si 50–52, se 105–110, c2 90–100, e1 50 –53, e2 11 –12, f1 5–6, 2a 12–14, 2b 17–18, 3a 18–20, 4a 12–14.

FEMALE TRITONYMPH ( Fig. 41 ). Setae h2 stick-like, f2 and other dorsal idiosomal setae narrow lanceolate. Setae 3a and 4a short, about 10 long. Tarsus IV without setae.

Differential diagnosis. See key.

Etymology. The species name is derived from the generic name of the host and is a noun in apposition.

Type host and locality. Dinaromys bogdanovi from Montenegro (Cetinje) .

Hosts and distribution. This species is known so far only from the type host and locality.

Material examined. Female holotype ( ZISP T-My-32), 2 female and 1 female TN paratypes from Dinaromys bogdanovi, MONTENEGRO: Cetinje, 10 May 1922, coll. V.E. Martino.

Type deposition. Radfordia dinaromys —ZISP, female holotype (T-My-32) and all paratypes (examined).
