Glandirana
''Glandirana'' is a genus of true frogs (family Ranidae) found in the East Asia (eastern China, Korea, Japan, and possibly Primorsky Krai in the Russian Far East). The name means ‘glandular frog’. ''Glandirana'' is a genus split off from ''Rana''. All species, except the recently described '' Glandirana susurra'', were originally included in ''Rana''; some of them have been placed in genus ''Rugosa'', now synonymized with ''Glandirana''.

Glandirana Susurra
''Glandirana susurra'' is a species of frog in the family Ranidae, the "true frogs". It is endemic to Sado Island, Japan. It is the only endemic amphibian of the island. It is genetically close to the widespread '' Glandirana rugosa'', but it is morphologically distinguishable and postzygotically isolated from the latter species. Etymology The specific name ''susurra'' is derived from the Latin ''susurrus'' meaning "whispering" and refers to the relatively quiet advertisement call of this species compared to those of other sympatric anuran ('' Hyla japonica'' and '' Rhacophorus arboreus''). Evolution Both ''Glandirana rugosa'' and ''Glandirana susurra'' are present on Sado Island, but their ranges do not overlap: ''G. susurra'' occurs on the central part of the island while ''G. rugosa'' in the south and in the north. Together with the fact that the race of ''G. rugosa'' on Sida Island is only distantly related to ''G. susurra'', this suggests that ''G. susurra'' speciated on S ...

Glandirana Rugosa
The Japanese wrinkled frog (''Glandirana rugosa'') is a species of true frog native to Japan and introduced to Hawaii in the late 19th century. It has sometimes been regarded as a single species with the Imienpo Station frog The Imienpo Station frog (''Glandirana emeljanovi'') is a species of frog found in Northeast Asia.

Glandirana Tientaiensis
''Glandirana tientaiensis'', also known as Tiantai frog and Tientai rough-skinned frog, is a species of frog in the family Ranidae. Its name refers to its type locality, Tiantai. It is endemic to eastern China and is only known from Zhejiang and south-eastern Anhui provinces. Male ''G. tientaiensis'' measure and female in length. Their natural habitats are open, low-gradient large streams and small rivers at elevations of above sea level. They sometimes also occur in still-water pools close to streams.

''Glandirana minima'' (known as Fujian frog or little gland frog) is a species of frog in the family Ranidae. It is endemic to the eastern parts of the Fujian province, China, (in Fuzhou, Fuqing, Yongtai and Changle, Xianyou). Its natural habitats are rivers, swamps, freshwater marshes, intermittent freshwater marshes, ponds, and irrigated land. It is threatened by habitat loss.

Glandirana Emeljanovi
The Imienpo Station frog (''Glandirana emeljanovi'') is a species of frog found in Northeast Asia. It has sometimes been regarded as a subspecies of the Japanese wrinkled frog, ''Glandirana rugosa'', with which it shares many characteristics. It is found throughout the Korean Peninsula and adjacent northeast China. It is speculated to be or have been present in the Russian Primorye region as well, but attempts to find it there have been unsuccessful. The Imienpo Station frog is found at low elevations, from 100 to 300 meters above sea level. It favors still and slow-moving waters, such as river backwaters and rice paddies. Adult frogs are 4–6 cm in length. They lay eggs in the late spring, from late April to the end of May. The tadpoles overwinter in their immature state, only undergoing metamorphosis the following summer. Like the Japanese wrinkled frog The Japanese wrinkled frog (''Glandirana rugosa'') is a species of true frog native to Japan and introduced to ...

True Frog
True frogs is the common name for the frog family Ranidae. They have the widest distribution of any frog family. They are abundant throughout most of the world, occurring on all continents except Antarctica. The true frogs are present in North America, northern South America, Europe, Africa (including Madagascar), and Asia. The Asian range extends across the East Indies to New Guinea and a single species (the Australian wood frog (''Hylarana daemelii'')) has spread into the far north of Australia. Typically, true frogs are smooth and moist-skinned, with large, powerful legs and extensively webbed feet. The true frogs vary greatly in size, ranging from small—such as the wood frog (''Lithobates sylvatica'')—to large. Many of the true frogs are aquatic or live close to water. Most species lay their eggs in the water and go through a tadpole stage. However, as in most families of frogs, there is large variation of habitat within the family.

Rana (genus)
''Rana'' is a genus of frogs commonly known as the Holarctic true frogs, pond frogs or brown frogs. Members of this genus are found through much of Eurasia and western North America. Many other genera were formerly included here. These true frogs are usually largish species characterized by their slim waists and wrinkled skin; many have thin ridges running along their backs, but they generally lack "warts" as in typical toads. They are excellent jumpers due to their long, slender legs. The typical webbing found on their hind feet allows for easy movement through water. Coloration is mostly greens and browns above, with darker and yellowish spots. Distribution and habitat Many frogs in this genus breed in early spring, although subtropical and tropical species may breed throughout the year. Males of most of the species are known to call, but a few species are thought to be voiceless. Females lay eggs in rafts or large, globular clusters, and can produce up to 20,000 at one time. ...

Russian Far East
The Russian Far East (russian: Дальний Восток России, r=Dal'niy Vostok Rossii, p=ˈdalʲnʲɪj vɐˈstok rɐˈsʲiɪ) is a region in Northeast Asia. It is the easternmost part of Russia and the Asian continent; and is administered as part of the Far Eastern Federal District, which is located between Lake Baikal in eastern Siberia and the Pacific Ocean. The area's largest city is Khabarovsk, followed by Vladivostok. The region shares land borders with the countries of Mongolia, China, and North Korea to its south, as well as maritime boundaries with Japan to its southeast, and with the United States along the Bering Strait to its northeast. The Russian Far East is often considered as a part of Siberia (previously during the Soviet era when it was called the Soviet Far East). Terminology In Russia, the region is usually referred to as just "Far East" (). What is known in English as the Far East is usually referred to as "the Asia-Pacific Region" (, abbrevia ...

Primorsky Krai
Primorsky Krai (russian: Приморский край, r=Primorsky kray, p=prʲɪˈmorskʲɪj kraj), informally known as Primorye (, ), is a federal subject (a krai) of Russia, located in the Far East region of the country and is a part of the Far Eastern Federal District. The city of Vladivostok is the administrative center of the krai, and the second largest city in the Russian Far East, after Khabarovsk. The krai has the largest economy among the federal subjects in the Russian Far East, and a population of 1,956,497 as of the 2010 Census.

Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have taken ...
