Stylophore apunctate, 135–145 long. Idiosoma . Propodonotal shield with concave anterior margin, apunctate, bearing bases of setae vi, ve, si and c1, setae se located near this shield. Length ratio of setae vi: ve: si 1:1.2:1.2–1.4. Hysteronotal shield absent. Setae d2 2–3 times longer than d1 and e2. Setae f2 and h2 situated on oval pygidial shield. Setae h2 2–3 times longer than f2. Coxal fields I–IV apunctate. Legs. Fan-like setae p ’ and p” of legs III–IV with 4 tines. Lengths of setae: vi 20– 30, ve 25–35, si 30–35, c1 105–130, c2 95–105, se 115–145, d1 20, d2 45–65, e 2 15 –20, f 2 20–25, h2 45–60, ag1 55–65, tc ’ III–IV 15–20, tc” III–IV 30.

Type material. Female holotype, 13 female and 4 male paratypes from quill of secondary feather of Dendropicos fuscescens (Vieillot) ( Piciformes : Picidae ); KENYA, Mutanda, 17 September 1945, coll. unknown.

Type deposition. All type material is deposited in the AMU (Reg. No. AMU-SYR.445), except 2 female paratypes in the ZISP (Reg. No. ZISP-AVB-011-2908-066), and 1 female paratype in the NMK (NMK-03MH).

Additional material. From type host species; UGANDA, Bombo, 14 August 1923, coll. unknown: 2 females, deposited in the AMU (Reg. No. AMU-SYR.445B); UGANDA, Masindi, Bunyoro district, 4 December 1959, coll. unknown: 8 females, deposited in the AMU (Reg. No. AMU-SYR.445C); TANZANIA, Songea, 24 June 1964, coll. unknown: 7 females, deposited in the AMU (Reg. No. AMU-SYR.445D).

Differential diagnosis. This new species is morphologically similar to Syringophiloidus carolae Skoracki, Flannery et Spicer, 2009 described from Cardinalis cardinalis (Linnaeus) ( Passeriformes : Cardinalidae ) ( Skoracki et al. 2009). In females of both species, the infracapitulum is punctate; each lateral branch of the peritremes has 9– 10 chambers; the propodonotal shield is punctate; the hysteronotal shield is fused to the pygidial shield. These species are distinguished as follow: in females of Syringophiloidus picidus , each medial branch of the peritremes has 6–7 chambers; the length ratio of setae vi: ve: si is 1:1.2–1.3:1.7–2.3, and all of propodonotal and hysteronotal setae are discernibly serrated. In females of Syringophiloidus carolae , each medial branch of the peritremes has 3 chambers; the length ratio of setae vi: ve: si is 1:3–3.4:5–6.5, and all propodonotal and hysteronotal setae are lightly serrated.

Etymology. The specific name refers to the family name of the host.
