Female (holotype and 2 paratypes). Total body length 720 (including gnathosoma). Gnathosoma. Infracapitulum densely punctate. Each medial and lateral branch of peritremes with 4 and 6–8 chambers, respectively ( Fig. 4View FIGURES 1 – 6). Stylophore punctate, 170 (165) long. Movable cheliceral digit 140 (130) long. Idiosoma  . Propodonotal shield densely punctate. Length ratio of setae vi:ve:si 1: 1: 5–6. Propodonotal setae delicately ornamented ( Fig. 5View FIGURES 1 – 6). Bases of setae c 1 and se situated at the same transverse level. Setae d 2 and e 2 subequal in length. Hysteronotal shield bearing bases of setae d 2 and d 1, not fused to pygidial shield, both shields strongly sclerotized and densely punctate. Setae f 1 and h 1 subequal in length. Setae ps 2 1.3 longer than ps 1, genital g 2 1.2 longer than g 1. Genital plate weakly sclerotized. Length ratio of ag 1:ag 2:ag 3 1.3–1.5: 1: 1.6. Coxal fields I –IV punctate. Setae 3 c 2.2–2.3 times longer than 3 b. Legs. Fan-like setae p’ and p” of legs III –IV with 6–8 tines ( Fig. 6View FIGURES 1 – 6). Length ratio of setae tc’: tc” III –IV 1: 1.2. Lengths of setae: vi 20 (25–30), ve 20 (30), si 120 (120–130), c 2 155 (170–215), se 180 (155), c 1 180 (175), d 2 175 (155), d 1 165, e 2 170 (160), f 1 20, f 2 more than 215, h 1 20 (25), h 2 320 (305), ag 1 150 (120), ag 2 105 (90), ag 3 160 (145), g 1 20 (20), g 2 25 (25), ps 1 10 (15), ps 2 15 (20); tc’ 50 (45), tc” 60 (55), l’RIII 40 (30), l’RIV 30 (20), 3 b 25 (30), 3 c 55 (70).

MALE: Not found.

Type material. Female holotype and two female paratypes collected from the Grey-headed Social-Weaver Pseudonigrita arnaudi  ( Passeriformes  , Ploceidae  ), coll. E. Glowska, November 2010. DNA barcode GenBank Accession no. JX 266447View Materials, voucher no. EG 543. Because there was no variation between three obtained sequences (one haplotype), only one sequence was published.

Remarks. All available morphological data are given (characters, setae lengths and ratio of all specimens). The reason of some metric features of paratypes are missing is that, after tissue digestion, the exoskeleton of these weakly sclerotized mites becomes very delicate and during preparation can be damaged in part (e.g. broken setae).

Type deposition. Type material is deposited in the AMU.

Etymology. The name pseudonigritae  refers to the generic name of the host (noun, genus feminum, genetivus singularis).

Differential diagnosis. Syringophiloidus pseudonigritae  sp. nov. is morphologically most similar to Syringophiloidus seiuri (Clark)  described from the Ovenbird Seiurus aurocapilla (Linnaeus)  ( Passeriformes  , Parulidae  ) in the USA (redescribed in Bochkov & Galloway 2001). Females of both species are characterized by having the similar number of chambers in the lateral branches of the peritremes, setae si about five times longer than vi, setae f 1 and h 1 subequal in length, the same ornamentation of dorsal setae, and fan like setae p’ and p” with a similar number of tines. The females of S. pseudonigritae  are distinguishable from those of S. seiuri  by the following features: medial peritreme branch with four chambers, length ratio of setae vi: ve is 1: 1, and the lengths of setae d 1 165, e 2 160–170, h 2 305–320, ag 1 120–150, and ag 2 145–160. Females of S. seiuri  have the medial peritreme branch with six chambers, the length ratio of setae vi:ve is 1: 1.5, and the lengths of setae d 1 120–140, e 2 120–130, h 2 250–270, ag 1 90–110 and ag 2 125–135.
