Two very narrow, propodonotal shields bearing setae ve, si and se, medial shield very small, pear-like, apunctate. Setae vi situated posterior to level of setae ve. Setae c 1 and se situated at same transverse level. Setae vi, ve and si lightly beaded. Pygidial shield well developed, with vertical furrow, double-leaf, with minute punctions on whole surface, setae f 1 situated on small sclerotised projections.

Materials Examined
Type material. Female holotype, 2 female (NPF), 2 female (PF) and 3 male paratypes from Xiphocolaptes promeropirhynchus (Lesson) (Passeriformes: Furnariidae), COLOMBIA: Leticia, 12 December 1968, coll. L. E. Orozco. Type deposition. All type specimens in AMU.
Diagnosis
Differential diagnosis.Picobia makoli sp. nov. is morphologically similar to above descibed species, P. magellani sp. nov. In females of both species, the hypostomal apex is tapering; the movable cheliceral digit is edentate on the proximal end; setae vi are situated posterior to the level of setae ve; setae vi, ve and si are lightly beaded; the pygidial shield is well developed and with vertical furrow; setae ag 2 are situated posterolateral to ag 1 and claws of legs III–IV are equal in the size. This new species differs from P. magellani as follow: in females of P. makoli, each medial branch of the peritremes has 12 chambers; the propodonotal shield is divided into two lateral and unpaired medial sclerites; genital setae are situated on blunt-ended genital lobes; the lenghts of setae h 1, ag 1 and ag 2 are 140–150, 160 – 165 and 65–70 respectively; the length ratios of setae d 2: e 2 and f 1: h 1 are 1: 1 and 1: 1.9 respectively. In females of P. magellani, each medial branch of the peritremes has 5–7 chambers; the propodonotal shield is absent; genital setae are situated on sharp-ended genital lobes; the lenghts of setae h 1, ag 1 and ag 2 are 55, 60 and 35 respectively; the length ratios of setae d 2: e 2 and f 1: h 1 are 1.7: 1 and 1: 1 respectively.
Etymology
Etymology. This new species is named in honor of the great Polish acarologist—Prof. Joanna Mąkol (Wroclaw University of Environmental and Life Sciences, Wroclaw, Poland).
