Morphological characters of specimens from Phu Yen and Khanh Hoa Provinces agreed with the descriptions of Bourret (1942), Inger and Stuart (2010) and Pham et al. (2019). Size small (SVL 36.4 mm in male, n = 1; 33.0- 34.5 mm in females, n = 3), head slightly longer than wide (HL 15.5 mm, HW 15.0 mm in male; 12.5-14.2 mm, 12.3-13.7 mm in females); snout slightly pointed anteriorly in dorsal view; rostral length greater than eye diameter (RL 6.0 mm, ED 4.0 mm in male; 5.0- 5.3 mm, 4.3-4.5 mm in females); tympanum visible, round, approximately 50 % of eye diameter (TD 2.1 in male; 2.7-2.8 in females); vomerine teeth in two oblique ridges; tongue cordiforn, deeply notched posteriorly; vocal sacs absent in the male (Table 1 and Fig. 5). Arms short and thin; fingers free of webbing; tips of fingers blunt, not expanded into discs; nuptial pad absent on finger I in males. Tibia and thigh short; tips of toes blunt, not expanded into discs; webbing formula I 1–2 II 11 / 2 – 21 / 2 III 2 – 3 IV 31 / 2 – 11 / 2 V; tibio-tarsal articulation reaching between eye and tip of snout (Fig. 6). Skin texture in life: Dorsal surface of head and body with small tubercles; supratympanic fold distinct; dorsolateral folds present; ventral surface smooth. Colouration in life: Dorsal surface light brown or light yellow with small dark spots; a dark cross bar between the eyes and a ᴧ - shaped mark between the shoulders; thighs and tibia with dark brown cross bars; ventral surface cream; throat cream with dark pattern (Fig. 5). Distribution In Vietnam, this species is known from Lao Cai in the north southwards to Dong Nai and Kien Giang Provinces (Pham et al. 2019, Le et al. 2021, Frost 2025). Elsewhere, the species has been reported from Lao PDR, Cambodia, Thailand and Myanmar (Frost 2025). This is the first record of L. limborgi from Phu Yen and Khanh Hoa Provinces. Ecology The frogs were found between 19: 00 and 22: 30 h on forest paths. Surrounding habitat consisted of mixed secondary forest composed of small to medium hardwoods and shrubs. Air temperature was 23–30 ° C and relative humidity was 65–81 %.
