context_page_description: Buergeria otai is a species of frogs in the family Rhacophoridae. It is endemic to Taiwan and found in the eastern and southern parts of the island. Buergeria japonica, with whom Buergeria otai was confused before described as a distinct species in 2017, occurs in northwestern Taiwan. The two species have only a narrow contact zone and can be distinguished based on genetic markers, calls, and morphology.
context_section_description: Adult males measure 23–29 mm (0.91–1.14 in) and adult females 30–38 mm (1.2–1.5 in) in snout–vent length. The body is elongated and moderately slender. The tympanum is barely discernible, whereas the supratympanic fold is prominent. Males have comparatively large subgular vocal sac. The fingers are slender, without webbing, and bear medium-sized discs. The toes are long, partially webbed, and also bear medium-sized discs. Dorsal coloration is variable, depending on light conditions and the background. During daytime, resting frogs are usually grayish. Calling males at night show a range of colors, from gray, yellow, gold, light brown, to dark orange. There is a dark dorsal marking resembling letter X or H that may almost fade away. Females usually turn brownish during amplexus. The chin and the belly are gray-white. The chin has small irregular mottling and there are tiny white spots on the ventral side of the thighs.
  Buergeria otai can emit two types of calls, "short calls" consisting of regular, long and lasting consecutive pulses (usually about 16–17), and "long calls" that have a major peak at the beginning, a serial of vary rapid pulses, and usually an ending with another short peak. The former call is similar to the call of Buergeria japonica, whereas the latter is unique.
