Description. FEMALE, holotype. Total body length 605 (595–685 in 13 paratypes). Gnathosoma  . Infracapitulum punctate. Each medial branch of peritremes with 6–7 chambers, each lateral branch with 9–10 chambers. Stylophore punctate, 165 (155–170) long, basal part of its dorsum with striae ornament. Idiosoma  . Propodonotal shield punctate near bases of setae ve and si. Length ratio of setae vi: ve: si 1: 1.2–1.3: 1.7–2.3. Bases of setae c 1 and se situated at same transverse level. All propodonotal and hysteronotal setae are discernibly serrated, other idiosomal setae smooth. Hysteronotal shield fused to pygidial shield, punctate in posterior part, bases of setae d 2 and d 1 situated on this shield. All hysteronotal setae subequal in length. Genital plate present, bases of setae ag 2 and ag 3 situated on margin of this plate. Length ratio ag 1: ag 3 1: 1.6. Pseudanal setae subequal in length, genital setae g 1 slightly (1.2 times) longer than g 2. All coxal fields punctate. Legs. Fan-like setae p ’and p” of legs III and IV with 5 tines. Setae tc”III –IV about twice as long as tc ’ III –IV. Lengths of setae: vi 35 (25–35), ve 45 (30–45), si 60 (60–80), c 1 210 (215), c 2 (155–180), se (185–195), d 1 150 (130–145), d 2 150 (145–160), e 2 145 (115–155), f 1 15 (10–20), f 2 175 (150–180), h 1 25 (25–40), h 2 (315–395), ps 1 15 (10–15), ps 2 15 (15), g 1 30 (25–40), g 2 25 (25–40), ag 1 115 (110–160), ag 2 (115–155), ag 3 180 (145–205), tc ’ III –IV 25 (25–30), tc” III –IV 55 (55).

MALE (4 paratypes). Total body length 395–415. Gnathosoma  . Infracapitulum sparsely punctate. Each medial branch of peritremes with 6–7 chambers, each lateral branch with 9–10 chambers. Stylophore apunctate, 135–145 long. Idiosoma  . Propodonotal shield with concave anterior margin, apunctate, bearing bases of setae vi, ve, si and c 1, setae se located near this shield. Length ratio of setae vi: ve: si 1: 1.2: 1.2–1.4. Hysteronotal shield absent. Setae d 2 2–3 times longer than d 1 and e 2. Setae f 2 and h 2 situated on oval pygidial shield. Setae h 2 2–3 times longer than f 2. 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, c 1 105–130, c 2 95–105, se 115–145, d 1 20, d 2 45–65, e 2 15 –20, f 2 20–25, h 2 45–60, ag 1 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. 445 B); UGANDA, Masindi, Bunyoro district, 4 December 1959, coll. unknown: 8 females, deposited in the AMU (Reg. No. AMU-SYR. 445 C); TANZANIA, Songea, 24 June 1964, coll. unknown: 7 females, deposited in the AMU (Reg. No. AMU-SYR. 445 D).

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.
