Description
One sequence of 560 bps (16 S gene) from specimen IEBR A. 6348 (GenBank accession number PV 444294) of Limnonectes specimen from Son Hoa District, Phu Yen Province was similar (99.8 %) to the available sequence of L. phuyenensis (accession number MW 222163) on GenBank.
Morphological characters of specimens from Khanh Hoa Province agreed with the description of Pham et al. (2020). Size medium (SVL 61.5-69.9 mm in males, n = 4; 45.8 mm in female, n = 1); head slightly broader than long (HL 28.8-32.2 mm, HW 29.7-33.3 mm, HL / HW 0.96 in males; 19.9 mm, 29.5 mm, HL / HW 0.97 in female); rostral length short (RL / SVL 0.14-0.15 in males, 0.15 in female), greater than eye diameter (RL 8.6-9.9 mm, ED 7.2-8.4 mm in males; 7.0 mm, 5.9 mm in females); tympanum invisible, vomerine teeth present; lacking vocal sacs in males (Table 1 and Fig. 7).
Arms short, finger free of webbing, tips of fingers blunt, not expanded, fingers I with nuptial pad, composed of minute spines on dorsal surface and medial edge in males. Tibia shorter than thigh (FeL 29.2-31.7 mm, TbL 27.1-29.3 mm in males; 23.2 mm, 21.5 mm in female); tips of toes blunt, not expanded into discs toes webbed to distal of terminal phalanx; webbing well developed; tibio-tarsal articulation reaching to the tip of snout (Fig. 8).
Skin texture in life. Dorsal surface of head, body and flanks with ridges and tubercles; dorsal surface of tibia and foot distinctly tuberculate, covered with moderately dense, small, low tubercles; supratympanic fold present; dorsolateral fold absent.
Colouration in life. Dorsum yellowish-brown with dark brown markings; ventral surface white with brown markings (Fig. 7).
Distribution
In Vietnam, this species was previously known only from Phu Yen Province (Pham et al. 2020). This is the first record of L. phuyenensis from Khanh Hoa Province.
Ecology
The frogs were found between 19: 00 and 22: 30 h on the stones, on the ground or in the water of rocky streams. Surrounding habitat consisted of mixed secondary forest composed of large to medium hardwoods and shrubs. Air temperature was 22–29 ° C and relative humidity was 72–88 %.
