|Diagnosis||Diagnosis. Synophis zaheri can be differentiated from Diaphorolepis by an un- modified vertebral scale row with a single weak keel (versus a laterally expanded verte- bral scale row, bicarinate or smooth); from Emmochliophis by the presence of a loreal (versus absence); from S. bicolor by having 166–169 ventrals (versus 174–183) and 111–112 subcaudals (versus 129–143); from S. aff. bicolor by having 8 or 9 infralabials (versus 10 or 11) and lighter brown dorsal coloration in life (versus darker black); from S. cf. bicolor by having 166–169 ventrals (versus 184–193), 111–112 subcaudals (ver- sus 127–131), and 8 or 9 infralabials (versus 10–12); from S. calamitus by having two postoculars (versus one typically) and internasals in contact (versus divided typically); from S. lasallei by having 166–169 ventrals (versus 144–165), 19 dorsal scale rows at midbody (versus 21–23 typically), 8 or 9 infralabials (versus 10 or 11), and by having the anteriormost dorsal scale rows smooth (versus keeled); and from S. plectrovertebra- lis by absence of a nuchal collar (versus presence) and two postoculars (versus one).|
