The picture is of two vitticeps.
A few ways to help you tell the difference:
Lawsonii will rarely have any variation in colour towards the red and yellow spectrums.
The size of the beard (even at 9 months) is much bigger and more pronounced in vitticeps than lawsonii.
Lawsonii almost always have circular paired patterning following the spine, but not reaching the flanks, whereas vitticeps can have striations, paired circles or a mixture, that will regularly extend to the flanks and legs
Vitticeps have longer tails than lawsonii.
Vitticeps have larger heads (compared to body) than lawsoni
Attached are two pictures of 9 month old vitticeps and lawsonii's, so you can see the difference. Vitticeps on the left in the first picture, Vitticeps in the foreground in the second
Hope this helps!
