At last we have to deal with Hyppolais . In this genus the fossa tricipitalis is proximally the deepest, with a distict margin in the middle of the bone (caudal view), tuberculum ventrale stronger than in other genera of the family, with a characteristic insertion-surface, the whole bone (chiefly H. icterina ) extremely robust (caudal view). The discussed two species H. icterina and H. pallida absolutely differ in their measurements (see measurements).

Ficedula ). The humerus of members of this genus belongs to the morphotype in which the fossa tricipitalis is deep, but not pneumatic (as in Paridae), the 'crus dorsale fossae ("bone bridge") well developed, separating the two fossae (taxonomical key No. 7. (6)] . We can characterize the corresponding bone of the flycatchers as follows: beside the features, mentioned above, contrary to smaller Turdidae ( Phoenicurus , Oenanthe ) of the same size and morphotype, in caudal view whole proximal epiphysis more shortened, laterally widened, crista lateralis shorter, with rectilinear margine, tuberculum ventrale, in ventral view shorter, fossa tricipitalis shallower than f. pneumo-anconaea. The morphological differences shown by some African sub-Saharan viz. southern Asiatic flycatchers £e. g. Batis , Tchitrea (= Terpsiphonef ] speak for a polyphyletism (convergences) of this group.
