Rallus carvaoensis R. carvaoensis n. sp. belongs to the group of species that combine robust leg bones (in this case, excluding the femur) with reduced wings. It is smaller than R. lowei n. sp. from Madeira and larger than R. minutus n. sp. from São Jorge. Although no complete skulls are available, the premaxilla is longer and more curved than in R. aquaticus and R. montivagorum n. sp. (see Figure 8 B–E). The bill shape was probably similar to that of R. minutus n. sp. R. carvaoensis n. sp. has a shorter coracoid and humerus than R. montivagorum n. sp. from Pico (12% and 19% shorter, respectively; U = -2.448; p = 0.007, U = -2.714; p = 0.002) and R. aquaticus (26% and 29% shorter, respectively; U = -2.833; p <0.001, U = -2.842; p <0.001). The available forelimb bones (humerus and carpometacarpus) are around 30% smaller than in R. aquaticus, while the femur, tibiotarsus and tarsometatarsus are 12%, 17% and 26% smaller than in R. aquaticus, respectively. The humerus is longer (9%) than in R. minutus n. ... : Published as part of Alcover, Josep Antoni, Pieper, Harald, Pereira, Fernando & Rando, Juan Carlos, 2015, Five new extinct species of rails (Aves: Gruiformes: Rallidae) from the Macaronesian Islands (North Atlantic Ocean), pp. 151-190 in Zootaxa 4057 (2) on page 181, DOI: 10.11646/zootaxa.4057.2.1, http://zenodo.org/record/233597 ...
