Leptophis Bell, 1825 View in CoL
1. Dorsum with 2 dorsolateral green stripes in adults, separated from each other by a pale vertebral stripe, which always continues onto the tail; head without spots on parietal scales; head and dorsum are metallic green anteriorly in adults, with colouration changing gradually to metallic chestnut toward tail ..................................... ....................................................... Leptophis liocercus View in CoL ( Fig. 17d View Fig )
- Dorsum without dorsolateral stripes in adults, with black keels on all but outermost dorsal scales; dorsal and head scales with only a narrow black slight margin, with a small black spot on the centre of each parietal scale; dorsal colouration of the head and anterior body is bluish green, different from that of the posterior half of body ........................................... Leptophis marginatus View in CoL ( Fig. 17c View Fig )
Mussurana Zaher et al., 2009 View in CoL
1. Dorsal scales in 19 rows; 201–211 ventral scales in males and 209–218 in females; generally 8 supralabial scales; subcaudal scales divided; anal plate entire; dorsum entirely black or slightly darkened in adults, and red with large dark vertebral stripe and white neck ring in juveniles ........ Mussurana montana ( Fig. 23f View Fig )
1. 173–205 ventral and 137–189 subcaudal scales; anal plate divided; supralabial scales usually 8 or more; paired white or yellow ventral stripes absent, or if present, weak and restricted to extreme lateral edges of ventrals on anterior half of body; snout extremely long and acuminate; dark oral lining ............................ ............................................................ Oxybelis aeneus ( Fig. 17e View Fig )
1. Preocular scales contacting frontal scale .................................... 2
- Preocular scale does not contact frontal scale; non-melanic specimens possess a banded dorsal pattern of colouration with black and white/red/brown bands uniformly distributed throughout the dorsum; in melanic individuals, dorsum is uniformly black, while the belly is white with scattered black spots that increase in number front to rear ( Fig. 7a View Fig ) ..................... .................................................... Oxyrhopus clathratus View in CoL ( Fig. 23g View Fig )
2. Black bands never invade ventral scales, although they may reach the edge of ventral scales ........................................................... 3
- Black dorsal bands invade the ventral scales in adults; supralabial scales generally dark; black bands of similar size triads along the body and tail, sometimes with a reduced central black band on the anterior portion of the body ( Figs. 8a View Fig , 9a View Fig , 10a View Fig ) ....................... .......................................................... Oxyrhopus guibei View in CoL ( Fig. 23h View Fig )
3. Black bands not disposed in triads ............................................. 4
- Black bands disposed in wide triads, with black bands in the centre of the triad, larger than the neighbouring ones in the anterior region of the body, and the size of the interspaces is half the size of the entire triad; the belly may have black spots on the ventral scales; supralabial scales are generally white or slightly edged in black ( Figs. 7b View Fig , 8b View Fig , 9b View Fig , 10b View Fig ) ........................................... ................................................... Oxyrhopus trigeminus View in CoL ( Fig. 24c View Fig )
4. 100–126 subcaudal scales in males and 86–110 in females; lateral irregular dark bands may reach the edge of ventral scales, whereas adults may have grey-darkened dorsum with or without reddish bands ( Fig. 11a View Fig ) ........ Oxyrhopus petolarius View in CoL ( Fig. 24a–b View Fig )
- 58–71 subcaudals in males and 50–63 in females; diamond-shaped dark bands getting thinner towards the belly, not touching ventral scales, over red and/or white ground, with or without small black spots ( Fig. 11b View Fig ) .......................................................... ................................................ Oxyrhopus rhombifer View in CoL ( Fig. 24d–e View Fig )
