Syringophilopsis bartrami sp. nov.

( Figs. 11A, B and 12A–G )

Description. FEMALE, holotype. Total body length 1,260 (1,200–1,280 in 6 paratypes). Gnathosoma . Hypostomal apex with 1 pair of minute protuberances. Infracapitulum apunctate. Stylophore apunctate, 230 (220– 230) long. Each medial branch of peritremes with 2–3 chambers, each lateral branch with 13 chambers. Idiosoma . Propodonotal shield with deeply concave anterior margin, distinctly sculptured, bearing bases of setae vi, ve, si and c1. Length ratio of setae vi: ve: si 1:1.3–2:2.3–3.3. Setae c1 situated slightly posterior to level of setae se. Setae c2 and si situated at same transverse level. Hysteronotal shields absent. Pygidial shield apunctate with distinct rounded anterior margin. Both pairs of pseudanal setae equal in length. Both pairs of genital setae subequal in length and several times shorter than agenital setae. Length ratios of setae ag1: ag2: ag3 and g1: ag2 1:1:1 and 1:3.6– 5, respectively. Setae 3b and 3c subequal in length. Legs. Fan-like setae p' and p" of legs III and IV with 12 tines. Lengths of setae: vi 145 (130–150), ve 195 (190–250), si 335 (420–430), se 330 (350–450), c1 300 (350–430), c2 300 (335–455), d1 310 (335), d2 300 (310–455), e2 300 (365–410), f1 70 (70–110), f2 400 (400–460), h1 (60–80), h2 (450–550), ag1 230 (230–330), ag2 200 (215–330), ag3 250 (270–350), g1 and g2 70 (65–70), ps1 and ps2 40 (35–45), l'RIII 85 (80–85), l'RIV 70 (70), 3b 135 (140–180), 3c 150 (160–180).

MALE. Total body length 780 in 1 paratype. Gnathosoma . Stylophore apunctate, 180. Each medial branch of peritremes with 4 chambers, each lateral branch with 15 chambers. Idiosoma . Propodonotal shield deeply cleft on anterior margin, covered with minute punctuations, bearing bases of setae vi, ve, si and c1. Length ratio of setae vi: ve 1:1. Setae c1 situated posterior to level of setae se. Setae c2 situated posterior to si. Hysteronotal shield fused to pygidial shield, covered with minute punctuations. Setae d2 twice as long as d1 and e2. Agenital setae ag1–3 subequal in length. Legs. Fan-like setae p' and p" of legs III and IV with 9 tines. Lengths of setae: vi 50, ve 50, se 100, c1 130, c2 125, d1 25, d2 50, e2 25, f2 25, h2 120.

Type material. Female holotype, 6 female and 1 male paratypes (UMMZ BMOC #87-0608-2) from Spizella passerina (Bechstein) ( Passeriformes : Emberizidae ), USA: Michigan, Wayne Co., Plymouth, 6 May 1987, coll. M. Nemazi.

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

Additional material. One female (AMU-SYR.763) from type host species, USA: Texas, Jeff Davis Co., Fort Davis , 12 April 2005, coll. G. S. Spicer (field no. GSS 1629), specimen in AMU.

Differential diagnosis. S. bartrami sp. nov. is morphologically similar to S. sittae . In females of both species, the hypostomal apex is ornamented by one pair of the protuberances; the hysteronotal shields are absent; setae ag1 and ag2 are subequal in the length. This new species differs from S. sittae as follow: in females of S. bartrami , setae ve are shorter than 260; posterior tips of apodemes I are fused with anterior parts of apodemes II, and in males setae vi and ve are equal in the length. In females of S. sittae , setae ve are longer than 320; posterior tips of apodemes I are fused with middle parts of apodemes II, and in males setae ve are 2–2.7 times longer than vi.

Etymology. This species is named on the honor of the great American naturalist - William Bartram (1739– 1823).
