MALE. Unknown.

Etymology. The specific epithet thamnophili  derives from the generic name of the type host.

Type material. Female holotype (physogastric form) and 4 female paratypes (2 physogastric and 2 nonphysogastric forms) from quills of body feathers of Thamnophilus insignis Salvin et Godman  ( USNM 639376) ( Passeriformes  : Thamnophilidae  ), GUYANA: Cuyuni- Mazaruni, Paruima, ca. 19 km N, at Mt. Holitipu, 25 February 2007, coll. B.K. Schmidt.

Non-type material. From Thamnophilidae  in GUYANA: 4 females (non-physogastric forms) from Myrmoborus leucophrys (Tschudi)  ( USNM 637174), Upper Takutu –Upper Essequibo, Lower Rewa River, 23 August 2006, coll. C.M. Milensky; 2 females (1 physogastric and 1 non-physogastric) from Myrmeciza ferruginea (St. Müller)  ( USNM 637194), Upper Takutu - Upper Essequibo, Upper Rewa River, 9 August 2006, coll. B.K. Schmidt; 12 females (10 physogastric and 2 non-physogastric) from Myrmotherula longipennis Pelzeln  ( USNM), Upper Takutu –Upper Essequibo, Lower Rewa River, 19 August 2006, coll. C.M. Milensky; 6 (5 physogastric and 1 non-physogastric) females from Hypocnemis cantator (Boddaert)  , Upper Takutu –Upper Essequibo, Lower Rewa River, 23 August 2006, coll. C.M. Milensky.

Material deposition. Holotype female and 2 female paratypes are deposited in USNM, 2 female paratypes in AMU. Additional material, 2 females from Myrmoborus leucophrys  , 1 female from Myrmeciza ferruginea  , 6 females from Myrmotherula longipennis  and 3 females from Hypocnemis cantator  are deposited in USNM, 2 females from Myrmoborus leucophrys  , 1 female from Myrmeciza ferruginea  , 6 females from Myrmotherula longipennis  and 3 females from Hypocnemis cantator  are deposited in AMU.

Differential diagnosis. This new species is most similar morphologically to Rafapicobia dendrocolaptesi Skoracki and Solarczyk, 2012  described from Dendrocolaptes platyrostris Spix  from Paraguay and D. picumnus Lichtenstein  from Argentina ( Skoracki and Solarczyk 2012). In females of both species, the hysteronotal shields are present and restricted to small punctate areas bearing bases of setae d 1, setae ag 2 are short (10–15 and 15–20 in R. dendrocolaptesi  and R. thamnophili  sp. nov., respectively), most of dorsal setae are beaded, all shields are punctate and antaxial and paraxial members of claws pairs III –IV are subequal. Females of R. thamnophili  sp. nov. differ from R. dendrocolaptesi  by the propodonotal shield generally divided into three parts, two narrow lateral sclerites bearing bases of setae si and se, punctate along the outer edge and the central shield bearing bases of setae vi, ve and c 1 (in some specimens lateral sclerites are fused with the central part unilaterally or bilaterally) and lengths of setae ve 75–95, d 2 130–145 and h 1 65–70. In females of R. dendrocolaptesi  the propodonotal shield is entire and lengths of setae are ve 45–60, d 2 165–190 and h 1 10.
