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. 3058405330 from Scytalopus magellanicus (Gmelin) (Passeriformes: Rhinocryptidae) NPF, PF Colombia Bogota 42 43 8 8 Bogota holotype 3058405339 [915,1363,1543,1568] ZSM 42 43 1 1 paratype 3058405319 ZISP 42 43 1 1 paratype
