Syringophiloidus auduboni  sp. nov.

( Figs. 5A, BView FIGURE 5 and 6A –DView FIGURE 6)

Description. FEMALE, holotype. Total body length 690 (680–700 in 7 paratypes). Gnathosoma  . Infracapitulum sparsely punctate or apunctate. Stylophore with striae ornament, apunctate, 145 (145) long. Each medial branch of peritremes with 3 chambers, each lateral branch with 7–10 chambers. Idiosoma  . Propodonotal shield well sclerotized, densely punctate, anterior margin rounded, setae vi, ve, si, se and c1 situated on this shield. Setae vi, ve and si lightly serrate. Length ratio of setae vi: ve: si 1:1:5.5. Bases of setae c1 and se situated at same transverse level. Hysteronotal shield not fused to pygidial shield, punctate, anterior margin of this shield reach above level of setae d2, posterior margin indistinct reach below level of setae d1. Setae d2 slightly (1.1–1.2 times) longer than e2. Pygidial shield punctate with indistinct anterior margin, strongly sclerotized in posterior part. Setae f1 and h1 subequal in length. Both pairs of pseudanal setae equal in length. Genital plate absent. Both pairs of genital setae equal in length. Length ratio of setae ag1: ag2: ag3 1–1.2:1:1.2–1.4. Coxal fields I –II with striae ornament, sparsely punctate, III –IV densely punctate. Legs. Fan-like setae p' and p" of legs III and IV with 6 tines. Setae tc' and tc" of legs III and IV subequal in length. Lengths of setae: vi 30 (20–30), ve 30 (20–30), si 165 (145–160), se 185 (175– 185), c1 185 (175–190), c2 170 (155–170), d1 150 (170), d2 165 (180), e2 150 (145–150), f1 30 (30), f2 (215), h1 30 (30–35), h2 280 (280–285), ag1 145 (135–145), ag2 120 (120–130), ag3 165 (155–165), g1 and g2 35 (35), ps1 and ps2 30 (20–30), l'RIII 45 (40–45), l'RIV 40 (35–40), tc'III – IV 45 (45), tc" III –IV 50 (50), 3b 35 (25–35), 3c 80 (80–90).

MALE. Not found.

Type material. Female holotype and 9 female paratypes (AMU-SYR. 757) from Spizella breweri (Cassin)  ( Passeriformes  : Emberizidae  ), USA: California, Riverside Co., 6 April 2006, coll. G. S. Spicer (field no. GSS 1746).

Type deposition. All type material in AMU, except 1 paratype in FMNH, 1 in UMMZ, and 1 in ZISP.

Differential diagnosis. S. auduboni  sp. nov. is morphologically similar to S. sialius Skoracki et al. 2009  . In females of both species setae vi and ve are subequal in length; setae si are 4.5–5.5 times longer than vi; both pairs of pseudanal setae are equal in length; the hysteronotal and pygidial shields are not fused to each other, and setae ag1 and ag2 are subequal in length. This new species differs from S. sialius  by the following features: in females of S. auduboni  , each lateral branch of the peritremes has 7–10 chambers; the stylophore is 145 long; the hysteronotal shield is distinctly punctate; setae tc' and tc" of legs III and IV are subequal in length, and setae ag3 are 155–165 long. In females of S. sialius  , each lateral branch of the peritremes has 11–12 chambers; the stylophore is 165–170 long; the hysteronotal shield is apunctate; setae tc"III –IV are 1.6 times longer than tc'III –IV, and setae ag3 are 125 long.

Etymology. This species is named in honor of an American ornithologist and naturalist—John James Audubon (1785–1851).
