665B43FC205A54ABB2EFB59C8169A8B0.taxon	etymology	Etymology. The specific epithet is named for Sanjie Liu, referring to a famous woman in Chinese ancient legend who came from Guangxi and who was known for her exceptional singing talent. The specific name means that the new species is distributed in Guangxi and its advertisement calls are melodic. We suggested “ Maoershan small tree frog ” for the common English name and “ 刘三姐纤树蛙 (Liú Sān Jiě Xiān Shù Wā) ” for the common Chinese name.	en	Wu, Xiangjian, Pan, Yuanqiang, Chen, Ju, Ye, Jianping, Yu, Guohua, Zou, Tongxiang (2025): Integrative taxonomic evidence for a new species of genus Gracixalus (Anura, Rhacophoridae) from Mao'er Mountain, Guangxi, China.

665B43FC205A54ABB2EFB59C8169A8B0.taxon	diagnosis	Diagnosis. The new species is assigned to genus Gracixalus based upon the following set of morphological characters: tips of digits enlarged to discs bearing circum-marginal grooves, vomerine teeth absent, inner (first and second) and outer (third and fourth) fingers not opposable, and an inversed Y-shaped dark brown marking on the dorsum (Fei 1999; Yu et al. 2019; Tran et al. 2023). The new species can be distinguished from its congeners by a combination of the following morphological characters: (1) SVL 27.5 – 33.2 mm in males and 38.1 ‒ 39.7 mm in females; (2) dorsal surface beige to brown; (3) dorsal surface rough with a few flatten tubercles on dorsum; (4) internal vocal sac in males, vocal sac opening slitted; (5) throat relatively smooth with barely visible tubercles; (6) finger webbing rudimentary; (7) linea masculina absent; (8) snout rounded; (9) tibiotarsal articulation reaching center of eye; (10) tibiotarsal projection absent; (11) nuptial pads present on fingers I and II; (12) heels slightly overlapping when legs at right angle to body; (13) ventral surface translucent, creamy white with dark blotches; (14) belly granular.	en	Wu, Xiangjian, Pan, Yuanqiang, Chen, Ju, Ye, Jianping, Yu, Guohua, Zou, Tongxiang (2025): Integrative taxonomic evidence for a new species of genus Gracixalus (Anura, Rhacophoridae) from Mao'er Mountain, Guangxi, China.

665B43FC205A54ABB2EFB59C8169A8B0.taxon	description	Description of holotype. Small size (SVL 33.2 mm); head wider (HW 12.1 mm) than long (HL 11.4 mm); snout rounded, slightly projecting beyond margin of lower jaw in ventral view, rounded in profile; canthus rostralis rounded; nostril oval, protuberant, closer to tip of snout than eye; loreal region oblique, slightly concave; interorbital distance (IOD 3.7 mm) nearly equal to internarial distance (IND 3.6 mm) and upper eyelid width (UEW 3.3 mm); eye large, horizontal diameter (ED 3.8 mm) slightly shorter than snout length (SL 4.2 mm); pupil oval, horizontal; tympanum distinct (TD 1.6 mm), slightly smaller than half of ED; supratympanic fold distinct, extending from posterior corner of eye to above insertion of arm; vomerine teeth absent; tongue notched posteriorly; single internal vocal sac, a pair of vocal sac slits on floor of mouth at both corners. Forelimbs relatively strong; forearm and hand length (FHL 17.4 mm) longer than 50 % of SVL; relative finger lengths I <II <IV <III; finger webbing rudimentary; tips of all fingers expanded into discs with circum-marginal grooves; subarticular tubercles prominent and rounded, formula 1, 1, 2, 2, the proximal one smaller than the distal one on fingers III and IV; two metacarpal tubercles, the outer divided into two; nuptial pads white, present on the base of the first and the second fingers. Heels meeting when legs at right angle to body; the relative lengths of the toes I <II <III <V <IV; tibiotarsal articulation reaching the middle of the eye when hindlimb adpressed to body; tip of toes expanded into discs with circum-marginal grooves; toe discs slightly smaller than finger discs; half web between toes, webbing formula I 2 – 2 ⅓ II 1 ½ – 3 III 1 ½ – 2 ⅔ IV 2 ⅓ – 1 ⅔ V; subarticular tubercles prominent, round, formula 1, 1, 2, 3, 2; a few supernumerary tubercles present; inner metatarsal tubercle oval, outer metatarsal tubercle absent. Dorsal surface rough, sparsely scattered with a few small flatten tubercles on the upper eyelids, head, dorsum, and limbs; white tubercles scattered on temporal region, edge of upper and lower jaw, and dorsal surface of limbs; flank rough, scattered with white tubercles; throat relatively smooth with barely visible tubercles; chest and belly granular, and ventral surface of thighs rough scattered with white tubercles. Coloration of holotype. In life, dorsal surface beige; a dark brown inverted Y-shaped marking on dorsal surface covering interorbital region, bifurcating into two branches on shoulder and extending posteriorly; dorsal surface of limbs beige with dark brown stripes; anterior and posterior parts of thigh light yellow; ventral surface of thigh light yellow mottled with light purple; discs of fingers and toes light yellow; flanks beige; throat and chest creamy white with dark speckles; iris bronze (Fig. 5). In preservative, color faded but pattern same as in life; dorsal surface gray-brown with a dark brown inverted Y-shaped marking; dark brown stripes on limbs; ventral surface dirty white with dark speckles (Fig. 6). Sexual dimorphism. Females are larger than males in body size. Males have white nuptial pads on the base of fingers I & II (Figs 5, 7 C) and internal single subgular vocal sac. Morphological variation. The dorsal surface of paratypes GXNU YU 000795 and GXNU YU 000979 is dark brown, whereas the dorsal surface of other types is beige or brown (Figs 7, 8). Paratypes GXNU YU 000962 and GXNU YU 000980 have less dark blotches on ventral surface (Fig. 8). In addition, the inverted Y-shaped marking on the dorsum in paratype GXNU YU 000980 is discontinuous (Fig. 8). Advertisement call. The advertisement calls of the new species consist of two notes (Fig. 9 A). The call duration of the new species is 0.66 ‒ 0.80 s (0.74 ± 0.04; Table 7) and the peak frequency is 2.58 kHz. The frequency range is 2.2 ‒ 2.9 kHz and the interval between calls ranges from 5.6 s to 18.2 s (8.9 ± 2.9). Distribution and ecology. Currently, the new species is known only from the type locality. The new species inhabits bamboo forest (Fig. 10) and enters breeding season in early April. Eggs with gel nests were found on the broken branches placed on the bottles that were used as artificial breeding trap for surveillance of tree frogs (Fig. 10), and calls were heard during the surveys. Zhangixalus minimus (Rao, Wilkinson & Liu, 2006) was also found at the type locality.	en	Wu, Xiangjian, Pan, Yuanqiang, Chen, Ju, Ye, Jianping, Yu, Guohua, Zou, Tongxiang (2025): Integrative taxonomic evidence for a new species of genus Gracixalus (Anura, Rhacophoridae) from Mao'er Mountain, Guangxi, China.
