Radfordia (Microtimyobia) synaptomysi Bochkov and Mironov, 1998: 309 , fig. 4

Diagnosis. FEMALE ( Fig. 35 ). Subcapitular setae m with 3–4 tines. Setae vi distinctly wider and longer than e2. Setae e1 and f1 filiform. Distances c1-d1 and d1-d2 subequal. Vulvar region not ornamented. Setae ps3 distinctly developed, slightly curved. Setae ag1 and ag2 subequal. Setae 1b and 1d slightly thicker than 1a. Setae 2a and 3a whip-like, much longer than 2b. Trochanter I with ventral projection, without tubercles. Measurements of holotype: body, including gnathosoma, 345 long (340–375 in 5 paratypes), 180 maximum wide (180–200). Lengths of setae: vi 56 (51–56), si 85 (85–90), se 80 (80–83), c1 60 (60–65), c2 67 (67–69), d2 56 (56–61), e1 12 (12–14), e2 27 (27–33), 2a 70–76, 4a 35–37.

MALE. Unknown.

FEMALE TRITONYMPH ( Fig. 36 ). Setae h2 stick-like, f2 and other dorsal idiosomal setae narrow lanceolate. Setae 3a and 4a short, much shorter than 2a. Tarsus IV without setae.

Type host and locality. Synaptomys borealis from North West of USA ( Bochkov & Mironov 1998) .

Hosts and distribution. This species was definitely recorded only on the type host, Synaptomys borealis from North West of USA (type series) ( Bochkov & Mironov 1998). The record of Radfordia lemnina from Synaptomys cooperi from USA (Indiana) ( Wassel et al. 1980) should probably be referred to Radfordia synaptomysi .

Material examined. Synaptomys borealis — Female holotype ( ZISP Т- My-12), 6 female and 1 female TN paratypes ( ZISP, unlisted), USA: North West of USA, August 1985, coll. R. Pitka.

Type deposition. Radfordia synaptomysi —ZISP, female holotype (T-My-12) (examined).
