Gnathosoma: Gnathosoma with numerous punctations on ventral side. Hypostomal apex rounded on anterior margin. Stylophore rounded on posterior margin 180 (175­180), long; extending below propodosomal plate. Peritremes, each lateral branch with 3­4 chambers, each transverse branch with 9 chambers ( Fig. 7View FIGURES 5 ­ 9).

The setal bases d 2 1.7 times closer to l 1 than to l 2. The length ratio of setae d 4: l 4 1: 8­8.7; d 5: l 5 1: 11­12.7. Paragenital setae pg 2 1.3 times shorter than pg 3. Two pairs of anal setae present. Cuticular striations as in figs 1­4.

Legs: Coxae well developed and punctated. Setae p’ and p’’ of legs III and IV with 6­7 tines ( Fig. 8View FIGURES 5 ­ 9). Setae tc’ III­IV 1.3­1.5 times shorter than tc’’ III­IV. Setae 3 c 3.0­ 3.3 times longer than 3 b.

Male ( Figs 5, 6 and 9View FIGURES 5 ­ 9). Total body length 420­490.

Gnathosoma: Gnathosoma with numerous punctuations on ventral side. Hypostomal apex rounded on anterior margin. Stylophore rounded on posterior margin 150­155 long. Peritremes, each lateral branch with 3­4 chambers, each transverse branch with 9­10 chambers ( Fig. 9View FIGURES 5 ­ 9).

Idiosoma: Propodosomal  plate weakly sclerotized. The setal bases vi, ve, sci and d 1 situated on this plate. All setae of body, smooth. The length ratio of setae vi: ve: sci 1: 1: 2.2. Hysterosomal plate very weakly sclerotized, setal bases d 2 and l 2 set on this plate. Pygidial plate weakly developed, bases of setae d 5 and l 5 set on or near this plate. The setal bases d 2 1.6 times closer to l 1 than to l 2. The setae l 1 1.3­1.5 times longer than d 2 and l 2. Setae d 5 8.8­9.3 times shorter than l 5. Cuticular striations as in figs 5, 6.

Legs: Coxae well developed and without many punctations. Setae tc’ III­IV 1.5 times shorter than tc’’ III­IV.

Lengths of setae: vi 25­30; ve 30; sci 55­65; h 65­80; sce 95; l 1 20­25; l 2 15; l 5 185­ 220; d 1 150­155; d 2 15; d 5 20­25; ic 1 70; ic 3 45; 3 b 25; 3 c 60­70; tc’ III­IV 30­35; tc’’ III­ IV 55; pg 1 105­110; pg 2 70­75.

Eytomology. The name tarnii  refers to the specific host name ­ Pteroptochos tarni  .

Differential diagnosis. The new species is closely related to Syringophiloidus graculae Fain, Bochkov et Mironov, 2000  from Gracula religiosa intermedia  ( Passeriformes  : Sturnidae  ) from S. E. Asia (Fain et al. 2000). In both species setae ve are short (shorter than 90); setae sci are long (longer than 120); lateral branches of peritremes have fewer than five chambers; two pairs of anal setae are present.

Syringophiloidus tarnii  sp. n. may be distinguished from S. graculae  by the following. In females of S. tarnii  sp. n., each transverse branch of peritremes has 9 chambers; the length ratio of setae vi: ve is 1: 1.3­1.5; setae l 1 and d 2 are shorter than 150. In males setae sci are 55­65 long, the length of setae l 1 are 20­25 and these setae are 1.3­1.5 times longer than d 2 and l 2. In females of S. graculae  , each transverse branch of peritremes has 10­13 chambers; the length ratio of setae vi: ve is 1: 2; setae l 1 and d 2 are longer than 150. In males setae sci are 110­123 long; length of setae l 1 are 78­90, and these setae are 3­4 times longer than d 2 and l 2.

Type material. Female holotype, nine female paratypes, three male paratypes, 16 nymphae paratypes from covert feathers of the Huet­huet Pteroptochos tarni  ( Passeriformes  : Rhinocryptidae  ); 1977; Argentina­El Bolson, Rio Negro; leg. Kovacs. Holotype, six female paratypes, two male paratypes and 16 nymph paratypes are deposited at UAM; two female paratypes at SMB; two female paratypes and one male paratype at ZIN.
