Rafapicobia Skoracki, 2011

Genus Rafapicobia Skoracki View in CoL

Remark. Up to now, the genus Rafapicobia has included five species described from birds of the orders Passeriformes ( Furnariidae , Mimidae , Muscicapidae ) (4 species) and Gruiformes (Rallidae) (1) ( Skoracki et al. 2014). Gradually increasing the number of known species in this genus makes the previous diagnosis ( Skoracki 2011) is no longer sufficient. It mainly concerns such characters as the hypostomal apex shape (which is tapering), hysteronotal shields (present or absent), presence of small thorn-like protuberances on apodemes I (present or absent) and the presence of 3 pairs of aggenital setae and 1 pair of genital setae. Homology of setae ag2 and g seems to be unclear. In females of R. zirnitra Skoracki and R. toxostoma Sikora, Fajfer andt Skoracki homology of setae ag2 does not rise doubts, whilst in R. melzeri Skoracki, Unsoeld, Skorupski and Kavetska , R. dendrocaptesi Skoracki and Solarczyk and R. lepidocolaptesi Skoracki and Solarczyk , R. thamnophili sp. nov., and R. milenskyi sp. nov. arrangement of setae ag2, their thickness and length suggest they are rather genital than aggenital setae.
