NON-PHYSOGASTRIC FEMALE. Total body length 430–470 in two paratypes. Gnathosoma  . Hypostomal apex tapering ( Fig. 13View FIGURES 11 – 15). Infracapitulum apunctate. Borders between chambers in medial and lateral branches invisible ( Fig. 14View FIGURES 11 – 15). Stylophore 120 (115) long. Idiosoma  . Propodonotal shield shirt-shaped, punctate on whole surface, bearing bases of setae vi, ve, si and se. Setae strongly knobbed. Setae vi situated anterior to ve bases. Length ratio of setae vi: ve: si 1: 2–2.3: 2.5–2.8. Hysteronotal shield restricted to small punctate areas bearing bases of setae d 1.

PHYSOGASTRIC FEMALE: as non-physogastric form, body bulb-shaped in outline.

MALE. Unknown.

Etymology. This species is named in honor of the collector of the host specimen, C. M. Milensky.

Type material. Female holotype (non-physogastric form) and 2 female paratypes (1 non-physogatric females and 1 physogastric forms) from quill of body feathers of Conopophaga aurita (Gmelin)  ( USNM 637100) ( Passeriformes  : Conopophagidae  ), GUYANA: Upper Takutu - Upper Essequibo, Upper Rewa River, August 2006, coll. C.M. Milensky.

Type deposition. Holotype female is deposited in USNM, 2 female paratypes (non-physogastric and physogastric forms) in AMU.

Differential diagnosis. This new species is most similar morphologically to Rafapicobia dendrocolaptesi Skoracki and Solarczyk, 2012  . In females of both species, the propodonotal shield is shirt-shaped, bearing bases of setae vi, ve, si and se and punctate on whole surface, the hysteronotal shields are present and restricted to the small punctate areas bearing bases of setae d 1 and setae ag 2 are short (10–15). Females of R. milenskyi  sp. nov. differ from R. dendrocolaptesi  by the length of setae si 45–55, c 2 95–130, se 90, d 2 115–130, f 2 10–15 and h 1 30–35. In females of R. dendrocaptesi the lengths of these setae are si 75–80, c 2 155–190, se 130–140, d 2 165–190, f 2 100–135 and h 1 10.
