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 vi are situated distinctly posterior to the level of setae ve ; the pygidial shield is double-leaf, each with 1 spin-like outhgrowth; setae ag2 are situated posterolateral to ag1 . 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 f1 : f2 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 f1 : f2 are 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.
