Site: Quills of secondary feathers (Rs5). Type locality: USA, Texas, Jeff Davis Co., Fort Davis, 12 April 2005, G. Spicer coll. (GSS#1612). Type specimens: Female holotype and paratypes: 2 females, 1 male and 4 nymphs. Specimens deposited: Holotype and most paratypes deposited at NMNH, 1 female paratype at AMU. Etymology: The name empidonax refers to the generic name of the host – Empidonax hammondii . Additionalmaterial: 1 female and 5 nymphs from secondary quill (Ls6) of the same host species and locality as type material, 13 April 2005, G. Spicer coll. (GSS#1424). All material deposited at NMNH. Five females and 4 nymphs from secondary and primary quills (Rp1, Ls1) of Empidonax wrightii Baird, 1858 ; USA, Texas, Jeff Davis Co., Fort Davis, 13 April 2005, G. Spicer coll. (GSS#1326). All material deposited at NMNH, except 1 female at AMU. Differential diagnosis. This new species is most similar to S. fringilla ( Fritsch, 1958 ) described from Fringilla coelebs Linnaeus ( Passeriformes : Fringillidae ) from Germany ( Fritsch 1958 ). In both species, females have the hypostomal apex with 2 pairs of minute protuberances, the hysteronotal shields present, and setae d4 and d5 unequal in length. Syringophilopsis empidonax is distinguished from S. fringilla by the following characters: in females of S. empidonax , setae sce are situated distinctly anterior to the level of setae d1 and setae d4 are twice longer than d5 . In females of S. fringilla , setae sce and d1 are situated at the same transverse level and setae d4 are about twice shorter than d5 .
