In preservative, Boophis lilianae exhibits creamy yellow coloration on dorsal and ventral surfaces. A pink canthal stripe runs from snout tip to upper eyelid, and a thin brown line encircles the nostril. Upper eyelid is covered by brown blotches, bordered by pink spots. Two fine longitudinal parallel stripes appear on mid-dorsum that are formed by rows of pink spots. There is also a small pink fleck on the knee (Kohler et al. 2008).
In life this species shows translucent yellowish green coloration on the dorsum that appears transparent in the groin. A reddish canthal stripe runs from snout tip to upper eyelid. The thin reddish supratympanic line fades at level of urostyle. Upper eyelid is covered by reddish brown blotch, and between the eyes there is a weak brownish triangular fleck. Two fine longitudinal stripes appear on mid-dorsum that extendsfrom behind scapular region to urostyle. Between the stripes there are some irregular pink marbling spots. Reddish brown spots also appear on heel and knee. Dorsal surfaces of fingers, toes, and terminal discs look yellowish green. Ventral surfaces of limbs, chest and throat are colored a green shade of turquoise. Belly is white and bones are green. The inner iris looks silvery grey, with a fine brownish circular line. Outer iris is golden yellow, with a black triangular fleck above and below pupil. Posterior iris has black on the periphery, adjoined by light blue (Kohler et al. 2008).
A diagnosis of Boophis lilianae with other species of the genus Boophis shows that this treefrog is so far the smallest known species in the genus. It is distinguished from members of the B. rappiodes and B. mandraka species groups by a pigmented ventral side and from members of the B. albipunctatus and B. luteus species groups by lack of lateral dermal fringes along lower arm and tarsus. Moreover, it differs from B. baetkei in smaller adult male size (18.3mm SVL in B. lilianae vs. 30.8mm for B. baetkei) and mucronate male snout shape (vs. rounded in B. baetkei) and a relatively smaller tympanum, as well as lacking vomerine odontophores (Kohler et al. 2008; Wollenberg et al. 2008).
