10. Chrysocorypha , new genus ( Fig. 2 )

Type species. Tachyphonus delatrii Lafresnaye, 1847 .

Included species. Monospecific; includes only Chrysocorypha delatrii , currently recognized as Tachyphonus delatrii .

Diagnosis. This genus is diagnosed by the specific characters of Tachyphonus delatrii Lafresnaye, 1847 .

Etymology. The name, feminine in gender, is formed from the Greek χρυσός, “gold,” and Greek κορυφή, “crown” or “top of the head,” in allusion to the male’s tawny crest.

Comments. As explained in the previous section, Tachyphonus delatrii forms a strongly supported clade with T. surinamus , Lanio , and Rhodospingus ( Fig. 2 ). As is the case with T. surinamus , molecular phylogenies indicate that T. delatrii is not closely related to any one of these species in particular. Thus, unless a broad and exceptionally heterogeneous genus subsumes all six species involved, a new generic name is needed for T. delatrii . Accordingly, we provide Chrysocorypha for this purpose.
