Madagascarophis lolo can be identified from other species in its genus by its gray overall body color with a black vertebral stripe and dorsal alternating lighter gray splotches. It has 25 midbody scale rows, 189
ventral scales and 56 divided
subcaudal scales. With the exception of
M. fuchsi, it differs from all other
Madagascarophis species by having extended contact of posterior
infralabial scales.
M. lolo can be distinguished from
M. fuchsi by its slightly lower number of infralabial scales, with
M. lolo having around 10 infralabial scales, versus approximately 12–13 infralabial scales in
M. fuchsi. == Behavior ==
