Etymology. The specific epithet “ quetzali ” derives from the common name of the type host, which is the national bird of Guatemala . Type material. Female holotype , 12 female and 2 male paratypes from secondary covert quill of Pharomachrus mocinno Llave ( Trogoniformes : Trogonidae ); GUATEMALA , no other data. Host specimen deposited in ZSM (Reg. no. ZSM 81/13). Type deposition. Holotype and most part of paratypes deposited in AMU, except 2 female paratypes in ZISP, and 2 female paratypes in ZSM. Additional material. Four females and 2 males from secondary covert quill of Pharomachrus antisianus (Orbigny) ; ECUADOR , 20 July 1961 , no other data. Host specimen deposited in the ZSM (Reg. no. ZSM 64/515). All mite material is deposited in AMU, except 1 female and 1 male in ZSM. FIGURE 1. Syringophiloidus quetzali sp. nov. , female. A , dorsal view; B , ventral view. Differential diagnosis. Syringophiloidus quetzali sp. nov. belongs to the group “ glandarii ” and is closely related to S. molothrus Skoracki, Flanery and Spicer, 2009 described from Molothrus ater (Boddaert) ( Passeriformes : Icteridae ) in the United States (Skoracki et al . 2009). In females of both species, the hysteronotal shield is not fused to the pygidial shield; the genital plate is present; the propodonotal shield is apunctate; each medial branch of the peritremes has 2–3 chambers; setae ve and si are longer than vi , and setae ps1 and ps2 are subequal in length. This new species is distinguished from S. molothrus by the following characters: in females of S. quetzali , the propodonotal shield is weakly sclerotized and striae are visible; the length ratio of setae vi : ve is 1:2.2–2.4; the pygidial shield is densely punctate; setae d2 are slightly (1.2 times) longer than e2 , and fan-like setae p’ and p” of legs III and IV have 10 tines. In females of S. molothrus , the propodonotal shield is well sclerotized and striae are indiscernible; the length ratio of setae vi : ve is 1:2.8; the pygidial shield is sparsely punctate; setae d2 are 1.5 times longer than e2 , and fan-like setae p’ and p” of legs III and IV have 7–8 tines.

Genus Syringophilopsis Kethley Mites of this genus inhabit feather quills of primaries and secondaries, and up to now they have been reported from two host orders, Passeriformes and Coraciiformes (Skoracki et al . 2012).
