TABLE 8. Diagnoses for the three species of the Litoria ewingii Group redescribed or described.
CharacterLitoria ewingiiLitoria calliscelisL. sibilus sp. nov.Adult body sizemales 28–35 mm; females 28–45 mmmales 27–34 mm; females 28–45 mmmales 25–34 mm; females 28–43 mmBuildModerately robustModerately robustModerately robustFinger and toe pad sizePads wider than fingers (mean Fin3W/Fin3DW = 0.6) and toes (mean Toe4W/Toe4DW = 0.7)Pads wider than fingers (mean Fin3W/Fin3DW = 0.6) and toes (mean Toe4W/ Toe4DW = 0.7)Pads wider than fingers (mean Fin3W/Fin3DW = 0.6) and toes (mean Toe4W/Toe4DW = 0.7)Extent of webbingWebbing vestigial on the hands, relatively well-developed on the feet (typically extending from 1st–halfway between 1st and 2nd subarticular tubercle on the 4th toe, rarely extending to the 2nd)Webbing vestigial on the hands, relatively welldeveloped on the feet (extending to the 1st subarticular tubercle on the 4th toe)Webbing vestigial on the hands but relatively well-developed on the feet (extending to the 1st subarticular tubercle on the 4th toe)Posterior thigh patterningPosterior edge of thigh orangeyellow and usually plain, unpatterned (n=27/32), but sometimes with scattered dark spots, flecks or lines (n=5/32)Posterior edge of thigh orange-yellow and usually patterned with dark spots or blotches (n=10/11), occasionally plain (n=1/11)Posterior edge of thigh orangepink, usually patterned with dark spots and blotches (n= 26/27), occasionally plain (n=1/27),Inguinal patterningDark spots in the inguinal region usually absent (n=29/33), although occasionally present (n=4/33)Usually a single dark spot present in the inguinal region, most often at the junction of the thigh and body (n=7/11), sometimes 2–3 spots (n=1/11) or plain (n=3/11)Dark spots or blotches in inguinal region usually absent (n=23/27), sometimes a single spot may be present at the junction of the thigh and body (n=4/27),Number of sites with apomorphicnucleotide states in the ND4 gene (Table 4)81015
