Description
provided by AmphibiaWeb articles
Rana taipehensis has a small, narrow body with a maximum SVL of 40 mm. This species is brightly colored. Dorsally it is yellowish green to greenish brown, with light yellowish brown sides. Paired dorsolateral glandular folds are present as brownish black lines. Front and hind limbs are light brown with dark brown stripes. The abdomen and neck bear tiny spots and have three brownish black stripes each. Slanted dark brown blotches are present at the anterior front. Anterior is white in background mixed with a gray dotted web pattern. The tympanic membrane and the region behind and below it are dark blackish brown in color (Lue 1990).The status of this species in India is controversial; Frost notes in Amphibian Species of the World that this species has been confused with Rana erythraea and Rana tytleri.

Distribution and Habitat
provided by AmphibiaWeb articles
Rana taipehensis is limited to the northern parts of Taiwan, essentially confining the population to Taipei (Lue 1999). Previously, it was present in large numbers in the valleys, but is now rarely seen in the southern parts of Taiwan (Lue 1990). However, this frog is widespread in other parts of Asia, including Bangladesh, Cambodia (Stuart et al. 2006), China (Yang 2008), Hong Kong, Lao People's Democratic Republic (Stuart 2005), Myanmar (Wogan et al. 2008), Thailand (Chan-ard 2003), and Viet Nam (Orlov et al. 2002; Nguyen et al. 2005). It may also be present in Peninsular Malaysia but has not yet been recorded there (Van Dijk et al. 2004). Rana taipehensis populates areas from lowlands up to 800 m above sea level (Van Dijk et al. 2004). This species can be found in wet, damp crop fields, ponds, and hills with tea crop plants present (Lue 1990), as well as open grassy wetlands, rice paddies, river floodplains, and swamps in deciduous forests (Van Dijk et al. 2004).
Life History, Abundance, Activity, and Special Behaviors

They are found in dense tree masses in groups during the daytime (Lue 1990). Breeding occurs in standing water with thick vegetation at water's edge (Van Dijk et al. 2004).In areas with increased urbanization (and increased ambient noise), Rana taipehensis have been observed to call at a faster rate. It is not known whether this change in call rate interferes with calls of other species (Sun and Narins 2004).
Life History, Abundance, Activity, and Special Behaviors

The population is currently stable (Van Dijk et al. 2004). It can adapt to a variety of habitats, including agricultural ones (Van Dijk et al. 2004). However, despite its classification as Least Concern, the species is becoming more sensitive to any outside stresses in endangered regions, such as Taiwan (Lue 1990). It is known to occur within several protected areas (Van Dijk et al. 2004).
Relation to Humans

In some parts of the world, Rana taipehensis is treated as a pest and is eliminated (Lue 1990). In addition, pollution from insecticides presents a threat (Lin et al. 2008).
Hylarana taipehensis
provided by wikipedia EN
Hylarana taipehensis is a species of "true frog", family Ranidae. It has several common names, including Taipei frog, Taipei grass frog, two-striped grass frog, or striped slender frog.[2][3][4] Following its redelimitation in 2019, its range is now believed to extend from Taiwan and southern China (including Hainan) to Vietnam, Laos, Cambodia, and eastern Thailand.[2]
Description
Males are usually less than 3 cm (1.2 in) in snout-vent length and females less than 4 cm (1.6 in).[4] The dorsum is yellowish green to greenish brown and the sides are light yellowish brown. Paired dorso-lateral glandular folds are visible as brownish black lines. The limbs are light brown and have dark brown stripes. The abdomen and neck have tiny spots and have three brownish black stripes each. The tympanum and the region behind and below it are dark blackish brown in color.[3]
Habitat and conservation
Hylarana taipehensis occurs in open, grassy wetlands, rice paddies, river floodplains, and forest ponds and swampy areas in deciduous forests. It is often common. Breeding takes place at water edges sheltered by thickets.[1]
Hylarana taipehensis adapts to agricultural conditions; it could be threatened by pesticides. It is sometimes persecuted as a pest.[1] In Taiwan, it is considered endangered.[4] However, it is not considered threatened overall, and occurs in many protected areas.[1]
