Propodonotal shield distinctly punctate, bearing bases of setae vi, ve, si and c 1, setae se situated on or near this shield. Length ratio of setae vi: ve: si 1: 1.2–1.6: 1.6–2.3. Hysteronotal shield bearing bases of setae d 1 and d 2, sparsely punctate in anterior part or apunctate, not fused to pygidial shield. Setae d 2 variable in length, distinctly shorter than setae d 1 and e 2 or subequal to them in length. Pygidial shield with indiscernible anterior margin. Length ratio of setae f 1: f 2 1: 7.5–8.5. All coxal fields well sclerotised and distinctly punctate. Genital plate absent. Setae ag 1 and ag 3 subequal in length, both pairs 1.5–2 times longer than ag 2. Setae 3 c 2.5–2.6 times longer than 3 b. Legs. Fan-like setae p’ and p ” of tarsi III and IV with 7–8 tines. Setae tc”III–IV 1.6–1.9 times longer than tc’III–IV.

Each medial branch of peritremes with 3 chambers, each lateral branch with 11–12 chambers. Idiosoma   Edit . Propodonotal shield with indiscernible lateral margins, punctate in anterior part, bearing bases of setae vi, ve, si and c 1. Length ratio of setae vi: ve: si 1: 1: 1. Hysteronotal shield weakly sclerotised, sparsely punctate. Pygidial shield absent. Setae d 1, d 2 and e 2 subequal in length. Setae ag 1 1.2–1.5 times longer than ag 2. Setae 3 c 2–3.5 times longer than 3 b. Legs. Fan-like setae p’ and p” of tarsi III and IV with 5–6 tines. Lengths of setae: vi 15, ve 15–20, si 10–15, se 60–90, c 1 105–115, c 2 65, d 1 10, d 2 10–15, e 2 5 –10, f 2 10–15, h 2 90, ag 1 30–55, ag 2 20–45.

Type material. Female holotype, 4 female and 4 male paratypes from the Sandy Gallito Teledromas   Edit fuscus (Sclater and Salvin) ( Passeriformes   Edit : Rhinocryptidae   Edit ); ARGENTINA: Rio Negro, Cipolletti, Neuquén, 3856 'S 6759 'W, 17 December 1937, coll. Schumacher.

Type material deposition. All type material is deposited in the AMU, except 1 female and 1 male paratypes in the ZSM.

Differential diagnosis. Syringophiloidus teledromas   Edit sp. nov. is morphologically close to S. tarnii Skoracki and Sikora, 2002   Edit , also described from rhinocryptid host— Pteroptochos   Edit tarnii   Edit (King) from Argentina ( Skoracki & Sikora 2002). In females of both species, each medial branch of the peritremes has 2–3 chambers; setae ve are slightly longer than vi; coxal fields of legs I–IV are well developed and distinctly punctate; fan-like setae p’ and p” of the tarsi III–IV have 6–7 tines. This new species is distinguishable from S. tarnii   Edit by the following features: in females of S. teledromas   Edit , the propodonotal and hysteronotal shields are distinctly punctate; the length ratio of setae vi: si is 1: 1.6–2.3; length of setae si and ag 2 are 35–40 and 60–75, respectively. In males, the length ratio of setae vi: si is 1: 1 and length of setae si is 10–15. In females of S. tarnii   Edit , the propodonotal and hysteronotal shields are apunctate; the length ratio of setae vi: si is 1: 6.2–7.8; length of setae si and ag 2 are 155–195 and 105–135, respectively. In males, the length ratio of setae vi: si is 1: 2.2 and length of setae si is 55–65.

Etymology. The species name is derived from the generic name of the host and is a noun in apposition.
