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. FIGURE 1. Syringophiloidus teledromas sp. nov. , female.

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