Description
Description. FEMALE NPF (holotype). Gnathosoma. Hypostomal apex tapering. Infracapitulum and stylophore punctate. Movable cheliceral digit edentate on proximal end. Each medial branch of peritremes with 5–7 chambers, each lateral branch with ill-visible chambers. Idiosoma. Propodonotal shield absent. Setae vi situated distinctly posterior to level of setae ve. Setae se and c 1 situated at same transverse level. Setae vi, ve and si lightly beaded. Pygidial shield well developed, with vertical furrow, double-leaf, apunctate. Setae ag 2 situated posterolateral to ag 1. Large, punctate genital plate bearing setae ag 1–3. Setae g 1 filiform, situated on sharp-ended genital lobes. All coxal fields punctate. Legs. Paraxial claws of legs III and IV thiner than antaxial claws III–IV. Solenidia σ on genua I setiform. Mesurements. Total body length 495. Length of stylophore 125.

Materials Examined
Type material. Female holotype (NPF) and 7 female (PF) paratypes from Scytalopus magellanicus (Gmelin) (Passeriformes: Rhinocryptidae), COLOMBIA: Bogota, no other data. Type deposition. All type material is deposited in the AMU, except 1 female (PF) paratype in ZSM and 1 female (PF) paratype in ZISP.
Diagnosis
Differential diagnosis.Picobia magellani sp. nov. is morphologically most simillar to P. schmidti Glowska and Milensky, 2014. In females of both species, the hypostomal apex is tapering; the lateral branches of the peritremes are with ill-visible chambers; setae vi are situated distinctly posterior to the level of setae ve; the pygidial shield is double-leaf, each with 1 spin-like outhgrowth; setae ag 2 are situated posterolateral to ag 1. This new species differs from P. schmidti as follow: in females of P. m a g e l l a n i, the propodonotal shield is absent; the length ratios of setae ve: si and f 1: f 2 are 1: 1.5 and 1: 1. In females of P. schmidti, the lateral propodonotal shields are present, each bearing bases of setae ve and si; the length ratios of setae ve: si and f 1: f 2 are 1: 4 and 1: 1.8–2.3.
Etymology
Etymology. The name of this species is derived from the specific name of the host— Scytalopus magellanicus, and is a noun in apposition.
