Abstract: Litoria pyrina sp. nov. Figs 13–15 Suggested common name: Ruddy Tree Frog Holotype. QM J95728 (Fig. 13), adult female from Carnes Rd, West of Georgetown, Qld (18.2997°S, 143.3514°E) collected by R. Catullo, G. Binns and K. Fahey on 15 January 2016. Paratypes. (Fig. 14). Five adult females: SAMA R34424, from Townsville, Qld, Australia (19.27°S, 146.82°E), collected in April 1988; SAMA R34441, from 4 km SE of Gayndah, Qld, Australia (25.63°S, 151.63°E), collected on 24 April 1989; AMS R54763, from Collarenebri Rubbish Tip, NSW, Australia (29.55°S, 148.58°E), collected on 17 April 1976; AMS R70085, from Goodnight Scrub, Mt. Perry Ranges, Qld, Australia (25.35°S, 151.92°E), collected on 25 September 1972; AMS R83984, from near Calliope, Qld Australia (24.00°S, 151.32°E), collected on 12 January 1955. Five adult males: SAMA R45911, from Mount Carbine, Qld, Australia (16.53°S, 145.13°E), collection date unknown; SAMA R55613, from Lily Hill, Boyne Island, Qld, Australia (23.94°S, 151.34°E), collected on 23 April 2001; AMS R53849, from Davies Creek Rd, Emerald Creek, 13 km SE Mareeba, Qld, Australia (17.08°S, 145.60°E), collected on 2 January 1974; AMS R84195, from Two Mile Creek to the north of Townsville, Qld, Australia (19.22°S, 146.78°E), collected on 24 February 1975; AMS R90635, from 6 km north-west of Maids Valle on Blaxlands Gap Rd, NSW, Australia (29.0800°S, 151.5917°E), collected on 19 March 1975. Material examined. Details of the 34 (10 females and 24 males) Litoria pyrina sp. nov. specimens examined are presented in Table 1 and tadpoles in Table 6. Diagnosis. This species exhibits characteristics typical of the Litoria rubella species complex: small head, rudimentarily webbed fingers, partially webbed toes, dark dorsolateral stripes and a high-pitched, multi-pulsed call. It is morphologically indistinguishable from other species in the L. rubella species complex and must be diagnosed using molecular data and location. From a genetic perspective, apomorphic nucleotide states at 16, 21 and 19 sites in the mitochondrial ND4 gene reliably diagnose L. pyrina sp. nov. from L. rubella, L. capitula and L. larisonans sp. nov. respectively (Table 3). Description of holotype. Adult female (Fig. 13); moderate body size (33.73 mm SUL); body moderately flattened and wide; head small (HDL/SUL = 0.26), flattened (HD/SUL = 0.14), and narrow (HDW/SUL = 0.29); head length approximately equal to width (HDL/HDW = 0.90); snout triangular in dorsal view, tip of snout blunt, rounded in profile; canthus rostralis rounded; loreal region steep, concave when considered in conjunction with upper labial margin; crown of head flat; nares ovate, on anterolateral edge of snout, oriented dorsolaterally; eyes small (EYE/HDL = 0.30), pupils oriented horizontally; eye to naris distance 1.2 X eye diameter; tympanum circular with raised annulus; well-developed supratympanic fold angling posteroventrally towards attachment of arm; tympanum and eye subequal in diameter (TMP/EYE = 0.79); arms moderate ([UAL+LAL]/SUL = 0.32), thin; fingers with basal webbing; relative length of fingers I<II<IV<III; tips of fingers with well-developed discs, distinct circum-marginal grooves and narrow fringing, discs relatively wide compared to width of the penultimate phalanx (third finger disc width 1.8 X third finger width); subarticular tubercles rounded; metacarpal tubercles ovate; hindlimbs short (TIB/SUL = 0.39); relative length of toes I<II<III<V
