Rallus adolfocaesaris Rallus adolfocaesaris n. sp. forms with the rails from Pico, Graciosa, Terceira and Santa Maria, a Macaronesian group of species that share the display of legs less robust and wings less reduced than R. lowei n. sp. The humerus of R. adolfocaesaris n. sp. is slightly more gracile than in R. aquaticus, but considerably wider than in R. lowei n. sp.. Its size (c. 33 mm in length) is similar to that of the Pico rail, and much larger than the São Miguel rail (20%) and São Jorge (31%) rails. The smaller humerus in relation to R. aquaticus suggests a shortening of the primary remiges, although this reduction was probably not so extreme as in R. lowei n. sp. The hindlimb bones are gracile compared to R. lowei n. sp., and short in relation to R. aquaticus. R. adolfocaesaris n. sp. has a femur close in length to those of R. lowei n. sp., and slightly longer than in the rails of São Miguel, Terceira and Pico, but shorter than in R. aquaticus (7%) and longer than in R. minutus n. sp.
