Lengths of setae: vi 25 (25–35), ve 40 (35–50), si 130 (100–135), se 230 (195–235), c1 195 (195–230), c2 (150–170), d1 130 (135–160), d2 35 (35–40), e2 135 (115–135), f1 (25–35), f2 (200–235), h1 35 (20–35), h2 320 (285–335), ag1 115 (80–115), ag2 (45–65), ag3 (155–170), g1 25 (25–30), g2 25 (25–30), ps1 15 (15), ps2 20 (20), tc’III– IV 30 (25–30), tc” III–IV 55 (55–30), 3b 35 (25–35), 3c 75 (70–95).

MALE. Unknown.

Type material. Female holotype and 11 female paratypes from Apus melba (Linnaeus) ( Apodiformes : Apodidae ); CHILE: Valdivia, 28 November 1924, coll. Ohde.

Type depositions. Holotype and 9 female paratypes are deposited in the AMU, except 1 female paratype in the ZSM and 1 female paratype in the ZISP.

Differential diagnosis. Syringophiloidus apus sp. nov. is similar to S. cypsiuri Fain, Bochkov and Mironov, 2000 described from Cypsiurus parvus (Apodidae) . In females of both species, each medial branch of the peritremes has 2–3 chambers; the propodonotal shield is apunctate; setae ag1 are longer than ag2, and the coxal fields are apunctate. This new species differs from S. cypsiuri by the following features: in females of S. apus , the length ratio of propodonotal setae vi: ve: si is 1:1.4–1.6:5.2–5.4; hysteronotal setae d2 are short, 3.7–4 times shorter than d1; agenital setae ag3 are 2.4–2.6 times longer than ag1; fan-like setae p' and p" of legs III–IV are with nine tines. In females of S. cypsiuri , setae ve and si are subequal in length and both pairs are 1.9–2 times longer than vi; hysteronotal setae d1 and d2 are subequal in length; agenital setae ag2 are 1.6 times shorter than ag3; fan-like setae p' and p" of legs III–IV are with 6–7 tines.

Etymology. The specific name " apus " refers to the generic name of the host— Apus .
