( Figs. 138 View FIGURE 138 and 139 View FIGURE 139 )

Type host: Nucifraga caryocatactes (Linnaeus) ( Passeriformes : Corvidae ). Type locality: Europe.

Description. FEMALE (holotype). Total body length 1035 (1000–1180 in 7 paratypes). Gnathosoma . Infracapitulum apunctate. Hypostomal apex with 2 pairs of short protuberances. Each medial branch of peritremes with 3 chambers, each lateral branch with 11 chambers. Length of apunctate stylophore and movable cheliceral digit 270 (265–270) and 190 (190–195) respectively. Idiosoma . Propodonotal shield with concave anterior margin, punctate at lateral margins, bearing bases of setae vi, ve, si and se. Length ratio of setae vi:ve:si 1:1.5–1.7:2–3. Setae se situated slightly anterior to level of setae c1. Hysteronotal shields absent. Pygidial shield present, apunctate. Setae f2 and h2 1.4–1.6 times longer than f1 and h1. Genital setae g1 and g2 subequal in length, both shorter than aggenital setae ag1 and ag3. Length ratio of setae g1:ag2 1:3.8. Setae ag1 1.3 times longer than ag2. Coxal fields I–IV apunctate. Setae 3c 1.3–1.4 times longer than 3b. Legs. Fan-like setae p’ and p” of legs III and IV with 15–16 tines. Setae tc’ and tc” of legs III and IV subequal in length. Apodemes I fused to apodemes II in middle part of apodemes II. Lengths of setae: vi 150 (150–200), ve 285 (290–320), si 435 (375–415), se 465 (410–450), c1 435 (410– 440), c2 465 (410–465), d1 (430–440), d2 (400–440), e2 (410–440), f1 350 (350), f2 500 (470–500), h1 305 (300– 320), h2 520 (500–565), ps1 and ps2 40 (40–45), g1 and g2 (80–90), ag1 (345–350), ag2 330 (255–305), ag3 380 (370–385), l’RIII 90 (90–105), l’RIV (90–95), tc’III–IV and tc”III–IV 100 (95–115), 3b 145 (125–145), 3c (180).

MALE. Unknown.

Type material. Nucifraga caryocatactes (Linnaeus) ( Passeriformes : Corviidae): female holotype and 8 female paratypes ( AMU –SYR.179) (sec.); EUROPE, 1909, no other data. Host specimen deposited in the MNHW .

Material deposition. Holotype and 6 female paratypes deposited in the AMU, 1 female paratype in the ZISP, 1 female paratype in the ZSM.

Host range and habitat. Monoxenous species inhabiting quills of secondaries of Nucifraga caryocatactes .

Etymology. The name nucifragus refers to the generic name of the host.

Diffrential diagnosis. This new species is morphologically similar to S. spinolettus . In both species, females have the genital setae shorter than the aggenital setae; setae c1 and se are situated at the same transverse level; the hysteronotal shields are absent. S. nucifragus is distinguished from S. spinolettus by the following characters: in females of S. nucifragus , the hypostomal apex is ornamented by 2 pairs of protuberances; each branch of the peritremes has 14 chambers; setae f2 and h2 1.4–1.6 times longer than f1 and h1 and the coxal fields are apunctate. In females of S. spinolettus , the hypostomal apex is ornamented by 1 pair of protuberances; each branch of the peritremes has 19 chambers; setae f1, f2, h1 and h2 are subequal in the length, and the coxal fields are punctate.
