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 visituated distinctly posterior to level of setae ve. Setae seand c1situated at same transverse level. Setae vi, veand silightly beaded. Pygidial shield well developed, with vertical furrow, double-leaf, apunctate. Setae ag2situated posterolateral to ag1. Large, punctate genital plate bearing setae ag1–3. Setae g1filiform, 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 σon genua I setiform. Mesurements. Total body length 495. Length of stylophore 125. Lengths of setae: vi115, ve115, si170, se180, c1170, c2180, d1170, d2170, e2100, f155, f260, h155, h2265, ag160, ag235, ag380, g150, ps125, ps230, tc’III–IVand tc”III–IV55. Length ratios of setae: vi: ve: si1:1:1.5, d2: e21.7:1, f1: f21:1, f1: h11:1, f2: h21:4.4, h1: h21:4.8, ag1:ag2:ag31.7:1:2.3, g1: ps2: ps12:1.2:1, tc’III–IV: tc”III–IV1:1. FEMALE PF ( 7 paratypes). Total body length 745–795. MALE. Unknown.
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.
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 viare situated distinctly posterior to the level of setae ve; the pygidial shield is double-leaf, each with 1 spin-like outhgrowth; setae ag2are situated posterolateral to ag1. This new species differs from P. schmidtias 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: siand f1: f2are 1:1.5 and 1:1. In females of P. schmidti, the lateral propodonotal shields are present, each bearing bases of setae veand si; the length ratios of setae ve: siand f1: f2are 1:4 and 1:1.8–2.3.
Etymology.The name of this species is derived from the specific name of the host— Scytalopus magellanicus, and is a noun in apposition.
