Type material. Remiz pendulinus (Linnaeus) ( Passeriformes : Remizidae ): female holotype and 1 male paratype ( AMU –SYR.239) (sec.); POLAND, Opolskie, Turawa Lake , 31 July 2004, coll. G. Hebda.

Type deposition. All material deposited in the AMU .

Host range and habitat. Monoxenous species inhabiting quills of secondary feathers of Remiz pendulinus .

Distribution. Poland.

Etymology. The name remizus refers to the generic name of the host.

Diffrential diagnosis. Neoaulonastus remizus is morphologically similar to N. bisetatus . In females of both species, the hysteronotal shield is present; setae f2 are no more than 3 times longer than f1; each vertical branch of the peritremes has 7–8 chambers and aggenital setae ag1 are longer than ag2. This new species is distinguished from N. bisetatus , by the presence of the following characters: in females of N. remizus , the total body length is 500; setae f2 are 3 times longer than f1; the length ratio of setae ag1: ag2: ag3 is 2:1:2.3; in males, the total body length is 350; the hysteronotal shield is not fused to the pygidial shield. In females of N. bisetatus , the total body length is 590–615; setae f2 are 2.3 times longer than f1; the length ratio of setae ag1: ag2: ag3 is 1.3–1.4:1:1.5–1.8; in males, the total body length is 405–460 and the hysteronotal shield is fused to the pygidial shield.
