Subfamily ZIPHIINAE Gray, 1850

TYPE GENUS. — Ziphius Cuvier, 1823 .

OTHER GENERA INCLUDED. — Choneziphius Duvernoy, 1851 , Globicetus n. gen., Imocetus n. gen., Izikoziphius Bianucci, Lambert & Post, 2007 , Tusciziphius Bianucci, 1997 , and possibly Caviziphius Bianucci & Post, 2005 .

EMENDED DIAGNOSIS. — With the exception of Izikoziphius and Ziphius , members of the subfamily Ziphiinae differ from all other Ziphiidae in the dorsal closure of the mesorostral groove by medial sutural contact of the premaxillae extending posteriorly until the bony nares. With the exception of Choneziphius and Imocetus n. gen., they further differ from all other Ziphiidae in having very elongated nasals with the anterior tip of nasals located anterior to the premaxillary crests (ratio between length of medial suture of nasals and maximum width of nasals> 1.1). ffley further differ from all other Ziphiidae , with the exception of the clade formed by Africanacetus Bianucci, Lambert & Post, 2007 , Hyperoodon , Ihlengesi Bianucci, Lambert & Post, 2007 , and Mesoplodon Gervais, 1850 , in having the ascending process of the premaxilla concave in lateral view, with the posterodorsal portion partly overhanging the bony nares (apart from Choneziphius planirostris ( Cuvier, 1823) , with bony nares still visible in dorsal view). ffley further differ from all other Ziphiidae , except Beneziphius , Messapicetus , and Ziphirostrum , in having the left premaxillary crest anterolaterally directed.
