Each medial branch of peritremes with 2–3 chambers, each lateral branch with 7–8 chambers. Stylophore 170 (170–185) long, basal part of its dorsum with striae ornament. Idiosoma  . Propodonotal shield weakly sclerotized, longitudinal striae visible, apunctate. Length ratio of setae vi: ve: si 1: 2.2–2.4: 4.8–5.7. Propodonotal setae thin with delicate ornament. Setae si, c 2 and se subequal in length. Hysteronotal shield not fused to pygidial shield, anterior end extending beyond level of setae d 2. Setae d 2 slightly (1.2 times) longer than setae e 2. Setae f 1 and h 1 subequal in length. Genital plate well sclerotized, bases of setae ag 2 and ag 3 situated on lateral margins of this plate. Both pairs of genital setae subequal in length. Agenital setae ag 3 slightly (1.2–1.3 times) longer than ag 1 and ag 2. Pseudanal setae ps 2 1.3 times longer than ps 1. Coxal fields I – IV sparsely punctate. Setae 3 c 2.6–3 times longer than 3 b. Legs. Fan-like setae p’ and p” of legs III and IV with 10 tines. Lengths of setae: vi 35 (30–40), ve 85 (70–95), si 170 (170–200), se (200–220), c 1 205 (200–220), c 2 190 (180–200), d 1 180 (175–220), d 2 (170–220), e 2 155 (150–180), f 1 30 (30–35), f 2 (215–245), h 1 30 (30–40), h 2 (355–380), ps 1 15 (15–20), ps 2 20 (20–25), g 1 (30–40), g 2 (30–40), ag 1 155 (140–155), ag 2 135 (130–140), ag 3 (180–190), 3 b 35 (35–40), 3 c 90 (90–105), l’RIII 40 (35–40), l’RIV 35 (35–45).

MALE. Total body length 400–405 in 2 paratypes. Gnathosoma  . Infracapitulum densely punctate. Each medial branch of peritremes with 3–4 chambers, each lateral branch with 7–8 chambers. Stylophore 145–150 long, with longitudinal striae in central part. Idiosoma  . Propodonotal shield poorly outlined, covered by minute punctuations, bearing bases of setae vi, ve, si and c 1. Length ratio of setae vi: ve: si 1: 1.2–1.3: 2. Hysteronotal shield weakly sclerotized, sparsely punctate, bearing setae d 1 and e 2. Pygidial shield apunctate. Setae d 2 variable in the length. Setae ag 1 slightly longer than ag 2. Coxal fields I –IV densely punctate. Setae 3 c about 3 times longer than 3 b. Lengths of setae: vi 25–30, ve 30–45, si 50–60, se 125–145, c 1 130, c 2 115–120, d 1 20–25, d 2 35–80, e 2 20 –25, f 2 20, h 2 215–235, ag 1 125, ag 2 70 –100, 3b 35, 3c 105, l’RIII 30, l’RIV 25.

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.

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 ps 1 and ps 2 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 d 2 are slightly (1.2 times) longer than e 2, 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 d 2 are 1.5 times longer than e 2, 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).
