MALE. Unknown.

Type material. Muscicapa dauurica Pallas ( Passeriformes : Muscicapidae ): female holotype and 9 female paratypes ( AMU –SYR.133) (sec.); JAPAN, no other data. Host specimen deposited in the MNHW.

Type deposition. All type material deposited in the UAM, except 1 female paratype in the ZISP .

Host and habitat. Monoxenous species inhabiting quills of secondary feathers of Muscicapa dauurica .

Distribution. Japan.

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

Diffrential diagnosis. S. muscicapicus is morphologically similar to S. turdus . In females of both species, the hypostomal apex is ornamented by 2 pairs of protuberances; setae c1 are situated posterior to the level of setae se; terminal setae h1 and f1 are in several times shorter than f2 and h2; genital setae are shorter than aggenital setae ag1 and ag3; the pygidial shield is small and weakly sclerotized. This new species is distinguished from S. turdus by the following characters: in females of S. muscicapicus , the small hysteronotal shields are present; the total body length is 705–815; the lateral branch of the peritremes has 8–10 chambers; the length of stylophore is 160–180 and tectals setae tc’ and tc” of legs III and IV are unequal in the length. In females of S. turdus , the hysteronotal shields are absent; the total body length is 1080–1125; the longitudidal branch of the peritremes has 11–13 chambers; the length of stylophore is 255–265 and tectals setae tc’ and tc” of legs III and IV are subequal in the length.
