Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| B. C. Livezey and L. D. Martin 1988 |
Diagnosis (necessarily limited to the humerus, the only element known for Dendrochen)--Distinguished from Dendrocygna and more primitive genera (Li- vezey, 1986) by the following synapomorphies (Table 2): orientation of capital shaft ridge toward external tuberosity and extension of capital groove under the head. Dendrocheninae distinguishable from Stictonetta, Plectropterus, Tadorninae, and Anatinae (Livezey, 1986) by greater anconal prominence of the ectepicondyle relative to the entepicondyle (plesiomorphy). Differs from Thalassornis in proximal orientation of capital shaft ridge (apomorphy) and relative anconal prominence of ectepicondyle and entepicondyle (ple- siomorphy; Table 2). Differs from Anserinae (Livezey, 1986) in several derived character states: orientation of humeral capital shaft ridge, lateral extent of capital groove, and absence of pneumatic fossa of humerus (Table 2). |
