Dicranurania , new genus

Type species.— Thalurania ridgwayi Nelson, 1900 .

Diagnosis.—Small hummingbird (size 9–10 cm) most closely related to Eupherusa . Tail forked (square in Eupherusa ). Tail blue (black in Eupherusa ), lacking white on the outer tail feathers in males (present and extensive in Eupherusa ). Secondaries and tertials lack red (present in Eupherusa ).

Included taxa.— D. ridgwayi is the only member of the genus.

Etymology.—Derived from the Greek δΙΚραΝΟΝ (dicranon) meaning pitchfork, and ΟΥραΝΙΟΣ (ouranios) meaning heavenly or sky blue, in reference to the forked blue tail. The ending of the new genus name forges a link with the genus Thalurania , in which it was previously included. The genus is feminine.
