MALE. Unknown.

Etymology. This new species is dedicated to Dr. David Furth, prominent American entomologist, expert on Alticinae beetles.

Type material. Female holotype and 5 female paratypes from coverts of black-headed paradise-flycatcher Terpsiphone rufiventer (Swainson) ( Passeriformes : Monarchidae ), GABON: Ogooue Maritime Province (Moukalaba-Doudou National Park, NW corner of N'dogo Lagoon), 14 April 2003, coll. B. K. Schmidt (mites removed by E. Glowska). USNM catalog number of the host: 631583.

Type deposition. Holotype female and 2 female paratypes are deposited in the USNM, 3 female paratypes in the AMU.

Differential diagnosis. This new species is morphologically similar to S. bombycillae Skoracki, 2002 described from the bohemian waxwing Bombycilla garrulus (L.) ( Passeriformes : Bombycillidae ) from Slovakia. In females of both species, the infracapitulum, the propodonotal shield and all coxal fields are punctate, dorsal setae are ornamented; number of chambers in the medial branches of the peritremes and the length ratios of setae vi:ve:si are similar. Females of S. furthi sp. nov. are distinguishable by the lateral branch of the peritremes represented by eight chambers, the punctate hysteronotal and pygidial shields, presence of the genital plate and by the length of setae ag1 125–155, ag2 80–105, ag3 145–180, and h2 320–335. In females of S. bombycillae , the lateral branch of the peritremes is represented by 10–12 chambers, the hysteronotal and pygidial shields are apunctate and the genital plate is absent. Length of setae ag1, ag2, ag3 and h2 are 165–200, 135–165, 240–250 and 405–450, respectively.
