(Figure 1 A–C)  
 Description. FEMALE (holotype and 4 paratypes). Total body length 575 (590). Gnathosoma. Infracapitulum apunctate. Stylophore apunctate, 155 (155) long. Each medial branch of peritremes with 6 chambers, lateral branch with weakly visible borders between chambers. Idiosoma. Propodonotal shield entire, densely punctate, bears all propodonotal setae, except c2. Length ratio of setae vi: ve: si 1:2–2.4:2.3–3. Setae c1 1.4–1.5 times longer than setae se. Setae c1 and se situated at same transverse level. Hysteronotal shield absent. Setae d2 1.2–1.3 times longer than setae d1. Pygidial shield well sclerotised, densely punctate on whole surface, except for three pairs of narrow apunctate patches. Setae f2 5.3 times longer than f1. Bases of setae 1a separated. Genital and agenital shields absent. Agenital setae ag1 8.5–12 times longer than setae ag2. Genital setae g1 2.5 times longer than pseudanal setae ps1 and 1.7–2 times longer than ag2. Coxal fields of legs I–IV well developed, all apunctate. Dorsal idiosomal setae vi, ve, si, se, c1, c2, d1, d2, e2 and ventral setae 3b, 3c, 4b; 4c ornamented with small tubercles, other idiosomal setae smooth. Legs. Most of dorsal setae of legs I and II ornamented with small tubercles. Claws of tarsi III and IV subequal in size and shape. Setae 3c and 4c 2–2.4 times longer than 3b and 4b. Setae tc”III–IV 1.4 times longer than tc’III–IV. Lengths of setae: vi 35 (40–45), ve 85 (80–90), si 105 (100–105), se 175 (160–165), c1 240 (240–250), c2 200 (180–185), d1 160 (160–195), d2 205 (205–235), e2 195 (205), ag1 170 (180–190), ag2 20 (15), ag3 190 (175–180), f1 15 (20), f2 80 (105), h1 20 (10–20), ps1 10 (10), ps2 14 (10), g1 25 (25–30), l’RIII 20 (20), l’RIV 20 (20), 3b and 4b 40 (35–40), 3c and 4c 80 (80–95), tc’III–IV 45, tc”III–IV 65.   
MALE. Unknown.  
 Type material. Female holotype and 4 female paratypes from Rufous-capped Motmot Baryphthengus ruficapillus (Vieillot) (Coraciiformes: Momotidae); BRAZIL, West Minas Gerais, Agua Suja, coll. O.A. de Carvalho [ZSM uncatalogued].   
 Type material deposition. All type specimens are deposited in the AMU (reg. no. AMU-SYR.579), except two female paratypes in the ZSM (reg. no. ZSM- 20112064).   
 Differential diagnosis. Rafapicobia momoti sp. nov. is morphologically similar to R. melzeri Skoracki, Unsoeld, Skorupski and Kavetska, 2014 known from four rail species (Gruiformes: Rallidae) (Skoracki et al. 2014). In females of both species, setae vi and ve are situated in close proximity to each other; the hysteronotal shield and agenital plate are absent; agenital setae ag2 are short (less than 30 µm); and the patches on the pygidial shield are present. This new species differs from R. melzeri by the following features: in females of R. momoti, the length ratio of setae vi: ve: si is 1:2.4:3; the length of setae d1 and g1 are 160 and 25 respectively; and coxal fields III and IV are apunctate. In females of R. melzeri, the length ratio of setae vi: ve: si is 1:1.5–1.7:2–2.3; the length of setae d1 and g1 are 115–125 and 10 respectively; and coxal fields III and IV are punctate.
