due to its possession of key characters such as: the anterior cephalic border between the frontal lobe and genal spine angle having a length (sag.) equal to the length (sag.) of LO; the anterior border being prominently separated from extraocular area by a furrow; the preocular furrow being directed inward and forward from the glabellar margin; S3 being jaggedly convex and conjoined adaxially; presence of lateral lobes on LO; the convex posterior margin of LO; and the intergenal angle roughly parallels a transverse line.
