Hylarana tytleri was initially described from a single specimen collected by Theobald, 1868 in Dhaka, Bangladesh. This holotype specimen is still in the collection of the Zoological Survey of India, Kolkata, although in poor condition.The holotype specimen itself is too damaged to determine its sex, but recent examination and comparison with recently collected specimen from the area (Ohler and Mallick 2003) leads them to believe the holotype is an adult male. From the holotype, H. tytleri was described as similar in size to H. erythraea, with a more pointed snout, a reddish-brown back, with no lateral stripe, and white on the upper lip.
Ohler and Mallick’s 2003 analysis distinguishes H. tytleri as frogs from Nepal, India, Myanmar, and Bangladesh, distinct from H. erythrae (eastern India and eastward) and also H. taipehensis (China and Indochina) based on morphometrics, with particular differences seen in snout-vent length and shank length.
Hylarana tytleri, Theobald’s ranid frog, is a common, lowland ranid frog from Asia that lives in quiet waterbodies and floodplains.Almost since its original description, there has been taxonomic confusion as to whether H. tytleri is a distinct species or a synonym of the wide-spread Southeast Asian common green frog (Hylarana erythraea). Recent morphometric analysis (Ohler and Mallick 2003) distinguishes it a distinct species occurring in Nepal, India, Myanmar and Bangladesh, an overlapping but different range from H. erythrae (much of southeast Asia) and also from H. taipehensis (China and Indochina). This analysis indicates that Hylarana tytleri is the largest of the three.
Hylarana tytleri inhabits a diversity of habitats up to 300 m asl in altitude.It is often found in bankside vegetation of pools, ponds and lakes.It breeds only in stagnant water.
Hylarana tytleri is collected for local consumption.It is impacted by deterioration of water quality (mostly by agrichemical pollution), but not considered threatened by the IUCN.

Hylarana tytleri is a frog species in the family Ranidae. It is found in eastern and northeastern India, Bangladesh, and southern Nepal, and possibly at lower elevations in Bhutan.[1][2] It was formerly placed in Rana, and included in the common green frog (H. erythraea). It is probably a close relative of that species nonetheless, and thus placed in the revalidated genus Hylarana, of which H. erythraea is the type species.[3] Common name Theobald's ranid frog has been coined for it, although common names for Indian frogs previously identified as Rana erythraea include yellow-striped frog, leaf frog, and leaping frog.[2]
Males grow to a maximum size of 33 mm (1.3 in) and females to 45 mm (1.8 in) in snout–vent length (SVL). The head is moderately elongated. The shanks are relatively long (about 55% of SVL). Webbing is partial. The body is uniformly greenish with two whitish or yellow lines laterally on back. There are two distinct brown lines on inner side of latero-dorsal folds. No mid-dorsal line is present.[4]
Hylarana tytleri is a lowland (below 300 m (980 ft) above sea level) species associated with a variety of aquatic habitats including pools, lakes, marshes, and artificially flooded agricultural areas. It may venture into bank side vegetation and into scrubland and tropical forest habitats. It is a common species, but water pollution with agrochemicals can be a threat. It may also suffer locally from over-collection for food. It is not considered a threatened species by the IUCN.[1]
