Setae 3c about twice longer than 3b. Legs. Fan-like setae p’ and p” of legs III and IV with 20–21 tines. Setae tc” of legs III and IV slightly (1.2–1.3 times) longer than tc’III-IV. Apodemes I fused in anterior part of apodemes II. Lengths of setae: vi (145), ve (220–265), si 410 (445), se 430 (440–465), c1 (465), c2 (430), d1 430 (400), d2 405 (465), e2 430 (445), f1 205 (220–250), f2 505 (480–505), h1 465, h2 495, ps1 and ps2 55 (50–55), g1 55 (50–55), g2 75 (115), ag1 320 (340), ag2 145 (155–180), ag3 340 (315–400), l’RIII 75 (70–75), tc’III– IV 70 (80–85), tc” III–IV 90 (95–115), 3b 105 (115), 3c 195.

MALE. Unknown.

Type material. Female holotype and 2 female paratypes (SYR.292) from secondary quills of Dicrurus adsimilis (Bechstein) ( Passeriformes : Dicruridae ), KENYA: Tsavo West National Park, Komboyo Campsite, 2 0 45’18.30”S, 38 0 06’55.25”E, 854m a.s.l., 9 December 2010, coll. M. Hromada and W. Wamiti.

Type depositions. Female holotype and 1 female paratype are deposited in the AMU, 1 female paratype in NMK.

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

Differential diagnosis. This new species belongs to the fringillae group and is morphologically similar to S. albicollisi Skoracki and Dabert, 2000 and S. melittophagi Skoracki and Dabert, 2001 described from meropid bird species (Coraciformes: Meropidae ) from Togo ( Skoracki & Dabert 2000, 2001) (see Table 1). In these three species, females have unequal in length terminal setae f1 and h1, setae vi are no longer than 150, and the apodemes of leg I are fused in anterior part of apodemes II. S. dicruri sp. nov. differs from the above mentioned species by the following characters. In females of S. dicruri , each medial branch of the peritremes has 2 chambers; the length of the stylophore is 280–285; setae se are situated anterior to the level of setae c1 and setae f1 are 205–250 long. In females of S. albicollisi and S. melittophagi , each medial branch of the peritremes has 4 and more chambers; the length of the stylophore is longer than 310; setae se and c1 are situated at the same transverse level; setae f1 are no longer than 160.
