Female holotype and paratypes : two females and one male from Rufous-headed Ground-Roll- er Atelornis crossleyi Sharpe ( Coraciiformes : Brachypteraciidae ); MADAGASCAR , Toamasina Prov. , near lake Alaotra, October 1925 , coll. unknown [host in the ZSM , uncatalogued]. Type material deposition. All type specimens are deposited in the AMU (reg. no. AMU–SYR .609), except one female paratype in the ZSM (reg. no. ZSM 20112065 ) . Differential diagnosis. Rafapicobia brachypteraci sp. nov. is morphologically most similar to R. lepidocolaptesi Skoracki and Solarczyk, 2012 known from two woodcreeper species of the genus Lepidocolaptes ( Passeriformes : Furnariidae ) from South America ( Skoracki & Solarczyk 2012 ). In females of both species, the propodonotal shield is entire; setae vi and ve are situated in close proximity to each other; agenital setae ag2 are short (less than 30 µm ); and two longitudinal and apunctate agenital plates are present. These two species are distinguishable by the following features: in females of R. brachypteraci , the length of the stylophore is 140–155; each medial branch of the peritremes has seven or eight chambers; and two hysteronotal shields are present. In females of R. lepidocolaptesi , the length of the stylophore is 120–130; each medial branch of the peritremes has four chambers; and the hysteronotal shields are absent.
