(Fig. 4)
Description. FEMALE (holotype). Total body length 445 (440–495 in 7 paratypes). Gnathosoma. Infracapitulum densely punctate. Each medial branch of peritremes with 2 chambers, each lateral branch with 4–5 chambers. Stylophore apunctate, 125 (125) long. Idiosoma. Propodonotal shield punctate, weakly sclerotized in anterior and posterior parts, bearing bases of setae ve, si and c1. Setae ve and si subequal in length. Setae c1 slightly (1.1–1.3 times) longer than se. Setae se and c1 situated at same transverse level. Hysteronotal shield present, situated between bases of setae d1 and e2. Setae d1, d2 and e2 subequal in length or setae e2 1.3 –1.5 times longer than d2. Pygidial shield apunctate, well sclerotized. Setae f2 1.8–2 times longer than f1. Setae ag1–3 subequal in length. Both pairs of genital setae subequal in length. Genital plate absent. All coxal fields densely punctate. Legs. Setae p’ and p” of legs III and IV with 7–8 tines. Setae tc”III–IV 1.3–1.5 times longer than tc’III–IV. Lengths of setae: ve 20 (20–25), si 20 (20–25), se 170 (150–170), c1 180 (180–190), c2 125 (115–125), d1 20 (20–30), d2 20 (20–30), e2 20 (20–35), f1 20 (20–25), f2 35 (35–40), h1 25 (25–30), h2 235 (225–240), ag1 65 (60–70), ag2 60 (55–65), ag3 60 (50–65), g1 and g2 30 (30), ps1 20 (20), tc’III– IV 30 (30), tc” III–IV 40 (40–45).
MALE. Unknown.
Type material. Female holotype and 7 female paratypes from Passer domesticus (Linnaeus) (Passeriformes: Passeridae); RUSSIA, Tula district, Suvorov, 28 May 2013, coll. V.V. Abramov. Type material deposition. All type material is deposited in the ZISP (Reg. No. ZISP-AVB-011-2908-069), except 4 female paratypes in the AMU (Reg. No. AMU-SYR.472).
Etymology. This species is named in honor of the great Russian acarologist, Prof. V.B. Dubinin.
Differential diagnosis. Krantziaulonastus dubinini sp. nov. is similar to K. buczekae (Skoracki, 2002) described from Sturnus vulgaris Linnaeus (Passeriformes: Sturnidae) from Poland (Skoracki 2002). In females of both species, the hysteronotal shield is present; the genital plate is absent, hysteronotal setae d1 and d2 are subequal in length. Females of these species differ from each other by the following features: in females of K. dubinini, the hysteronotal shield is not fused with the pygidial shield; the infracapitulum and all coxal fields are densely punctate; the length of the stylophore is 125; setae ag2 and ag3 are subequal in length. In females of K. buczekae, the hysteronotal shield is fused with the pygidial shield; the infracapitulum and all coxal fields are sparsely punctate; the length of stylophore is 145–150; setae ag3 are twice as long as ag2.
