Stylophore 140 (140–145) long, surface apunctate, basal half with longitudinal striae. Each medial branch of peritremes with 3 chambers, each lateral branch with 9–10 chambers. Idiosoma . Propodonotal shield distinctly punctate, bearing bases of setae vi, ve, si and c1, 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 d1 and d2, sparsely punctate in anterior part or apunctate, not fused to pygidial shield. Setae d2 variable in length, distinctly shorter than setae d1 and e2 or subequal to them in length. Pygidial shield with indiscernible anterior margin. Length ratio of setae f1: f2 1:7.5–8.5. All coxal fields well sclerotised and distinctly punctate. Genital plate absent. Setae ag1 and ag3 subequal in length, both pairs 1.5–2 times longer than ag2. Setae 3c 2.5–2.6 times longer than 3b. 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 . Propodonotal shield with indiscernible lateral margins, punctate in anterior part, bearing bases of setae vi, ve, si and c1. Length ratio of setae vi: ve: si 1:1:1. Hysteronotal shield weakly sclerotised, sparsely punctate. Pygidial shield absent. Setae d1, d2 and e2 subequal in length. Setae ag1 1.2–1.5 times longer than ag2. Setae 3c 2–3.5 times longer than 3b. 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, c1 105–115, c2 65, d1 10, d 2 10–15, e 2 5 –10, f 2 10–15, h2 90, ag 1 30–55, ag 2 20–45.

Type material. Female holotype, 4 female and 4 male paratypes from the Sandy Gallito Teledromas fuscus (Sclater and Salvin) ( Passeriformes : Rhinocryptidae ); 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 sp. nov. is morphologically close to S. tarnii Skoracki and Sikora, 2002 , also described from rhinocryptid host— Pteroptochos tarnii (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 by the following features: in females of S. teledromas , 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 ag2 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 , 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 ag2 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.
