Stylophore apunctate, 110 (110–120) long. Idiosoma  . Propodonotal shield entire, shirt-like, punctate at lateral margins, bearing bases of all propodonotal setae except c 2. Setae vi situated anterior to level of setae ve. All propodonotal setae lightly beaded. Length ratio of setae vi: ve: si 1: 2.3–3: 5–5.6. Setae c 1 and se located at same transverse level. Hysteronotal shield absent. Setae d 1 situated closer to setae e 2 than to d 2. Pygidial shield well developed, apunctate. Setae f 2 about 5 times as long as f 1.

Hysteronotal shield entire, well sclerotized, not fused to pygidial shield. Setae d 2 about 25 times longer than d 1 and e 2. Pygidial shield well developed, apunctate. Setae h 2 29–33 times longer than f 2. Aggenital plate absent. Length ratio of setae ag 1: ag 2 5.5: 1. Coxal fields I –IV well developed, apunctate. Setae 3 c 3 times longer than 3 b. Legs. Most of dorsal setae of legs I and II lightly beaded. Antaxial and paraxial members of claws pair III and IV subequal in size. Setae tc’ and tc” of legs III –IV subequal in length. Lengths of setae: vi 20, ve 65, si 95–105, se 120–140, c 1 120–130, c 2 115–120, d 1 5, d 2 105–125, e 2 5, f 2 5, h 2 145–165, ag 1 55, ag 2 10, 3b 25 –30, 3c 65–75, l’RIII 20, l’RIV 20, dTIII – IV 55.

Type material. Female holotype (physogastric form) and paratypes: 6 females (physogastric form), 7 males, 3 nymphs and 1 egg (AMU –SYR. 334) from Toxostoma  curvirostre (Swainson); UNITED STATES, Texas, Webb Co., Laredo, 29 March 1962, coll. L.W. Oring. Mites removed by M. Skoracki.

Type deposition. All material is deposited in the AMU, except 1 female and 1 male in the ZISP and 1 female in the ZSM.

Etymology. The name toxostoma  refers to the generic name of the host – Toxostoma  .

Differential diagnosis. The genus Rafapicobia was known only from the type species R. zirnitra Skoracki, 2011 described from Saxicola rubetra (Linnaeus)  ( Sylviidae  ) and Ficedula hypoleuca (Pallas)  ( Sylviidae  ) from Poland ( Skoracki 2011). This new species differs from the type species by the following characters: in females of R. toxostoma  sp. nov., the lengths of setae ve, si and f 2 are 75–105, 150 – 155 and 70–80 respectively; the propodonotal shield is entire; in males the length ratio of setae vi: ve: si is 1: 3.2: 4.8–5.3; the hysteronotal shield is not divided. In females of R. zirnitra, the lengths of setae ve, si and f 2 are 65, 80– 90 and 50–55 respectively; the propodonotal shield is divided into three shields; in males the length ratio of setae vi: ve: si is 1: 2.3: 3.7; the hysteronotal shield is divided longitudinally.
