Neopicobia pari sp. nov.

( Figs. 24 and 25 )

Description. FEMALE (holotype and 3 paratypes). Gnathosoma . Infracapitulum and stylophore apunctate. Each medial branch of peritremes with 5 chambers, each lateral branch with ill-visible borders between chambers. Idiosoma . Propodonotal shield entire, punctate, concave on anterior margin. Setae vi, ve and si strongly beaded. Setae c1 situated anterior to level of setae se. Hysteronotal shield absent. Pygidial shield sparsely punctate, without vertical furrow and wing-like appendages. Setae ag1 and ag2 situated in longitudinal row, setae ag2 and ag3 situated at same transverse level. Pseudanal setae thin and minute. Agenital and genital plates absent. Coxal fields I–II apunctate, III–IV sparsely punctate or apunctate, setae 4c on coxal fields. Legs. Claws of legs III and IV equal in size. Measurements. Total body length 440 (360–400). Stylophore 100 (100–105) long. Lengths of setae: vi 30 (25–30), ve 45 (45–55), si 70 (70–75), se 90 (90–100), c1 105 (105), c2 90 (85–90); d1 80 (85–95), d2 95 (95–100), e2 80 (85–100), f1 20 (20–25), f2 45 (45–55), h1 20 (20–25), h2 (135–145), ag1 65 (65–75), ag2 40 (45–55), ag3 65 (70–75), tc’III–IV 30 (30), tc”III–IV 30 (30), l’RIII 15, 3b 20 (20), 3c 60 (60–65). Length ratios of setae: vi: ve: si 1:1.5–2:2.3–3, d1: d2: e2 1:1:1, f1: f2 1:2–2.7, f1: h1 1:1, h1: h2 1:5.8–6.8, ag1: ag2: ag3 1.4–1.6:1:1.4–1.6, 3b: 3c 1:3– 3.2, tc’III–IV: tc”III–IV 1:1.

MALE. Unknown.

Type material. Female holotype and 6 female paratypes from Periparus venustulus Swinhoe ( Passeriformes : Paridae ), CHINA: Fuijan Prov. , 5 April 1912, coll. J. Gangler.

Type deposition. All type specimens in AMU, except 1 female paratype in ZSM.

Additional material. Two females from Parus major Linnaeus (Paridae) ; MACEDONIA: Has-Jenikoj , 3 March 1918, coll. L. Mueller, both specimens in AMU ; 5 females from same host species, FINLAND: Savonlinna , 1831, coll. J. Gengler, all specimens in AMU ; 3 females from Poecile varius Temminck and Schlegel (Paridae) , JAPAN: Honshu Isl., Fuji Mt. , 9 April 1900, coll. Haberer, all specimens in AMU .

Differential diagnosis. N. pari sp. nov. is morphologically similar to N. cardinalis ( Skoracki, Hendricks and Spicer, 2010) described from cardinalid host Cardinalis cardinalis (Linnaeus) in the USA ( Skoracki et al. 2010). In females of both species, the infracapitulum and the stylophore are apunctate; the propodonotal shield is entire and punctate; the hysteronotal shield and the agenital plate are absent; setae ag1 and ag3 are 1.4–1.6 times longer than ag2. This new species differs from N. cardinalis as follow: in females of N. pari , length of setae ve, si and f2 are 45–55, 70–75 and 45–55, respectively; setae vi, ve and si are strongly beaded. In females of N. cardinalis , length of seta ve ve, si and f2 are 105–115, 140–155 and 90–100, respectively; setae vi, ve and si are lightly beaded.

Etymology. The name of this species is derived from the family name of the hosts—Paridae, and is a noun in apposition.
