DiagnosisDiagnosis: Draco walkeri can be distinguished from all other members of the D. lineatus group by the following combination of characteristics: (1) the dorsal patagial coloration of males gray or brown proximally, black distally, with one to three tan or white radial bands anteriorly, the anteriormost radial bands most distinct, (2) male dewlap short and rounded distally, (3) dewlap in males pale yellow in coloration, (4) usual presence of a melanic interorbital spot, (5) presence of a melanic nuchal spot in males and females, (6) usual absence of a melanic postnuchal spot, (7) absence of white pigments in association with nuchal and variably present postnuchal spots, (8) presence of melanic ‘eye spots’ (dark spots with associated white or pale pigments) on the supraorbital semicircles of both sexes, (9) usual presence of a parietal lens (32/35), and (10) tympana variably unscaled, partially-scaled, or completely covered with scales (from MCGUIRE et al. 2007). 
CommentDraco walkeri has been previously synonymized with Draco (lineatus) beccarii by SMITH 1927 and HENNIG 1936. 
EtymologyNamed after James John Walker (1851-1939), who served in the Royal Navy and was an amateur natural historian and entomologist. He was on board HMS Penguin (1890-1892), which surveyed Australasian waters and the Pacific (1890-1907).
