Johann Georg Wagler

Johann Georg Wagler (28 March 1800 – 23 August 1832) was a German herpetologist[1][2][3] and ornithologist.[4]

Wagler was assistant to Johann Baptist von Spix, and gave lectures in Zoology at the Ludwig Maximilian University of Munich after that was moved to Munich.[5] He worked on the extensive collections brought back from Brazil by Spix, published partly together with him books on reptiles from Brazil. Wagler wrote Monographia Psittacorum (1832),[2] which included the correct naming of the blue macaws.

In 1832, Wagler died of an accidental self-inflicted gunshot wound while out collecting in München-Moosach.[1][2][3]

Wagler is commemorated in the specific names of three species of reptiles: Atractus wagleri, Podarcis waglerianus, and Tropidolaemus wagleri.[2]

Wagler described a taxonomic arrangement of psittacine fauna, parrots and cockatoos, some of which are recognised in the systematic classification of these birds.[4]

Blanus is a genus of amphisbaenians found in the Mediterranean region of Europe and North Africa. Like other amphisbaenians, Blanus are specialized for a subterranean existence, with a long, slender body, reduced limbs, and rudimentary eyes. The skull is powerfully constructed, allowing the animal to push through soil to create a burrow. The jaws are well-developed, with large, recurved teeth and a pair of canine-like teeth in the upper jaw.

Five extant species are currently known. The relationships of Blanus to other worm-lizards are not clear. The genus was formerly included in the Amphisbaenidae. More recent analyses suggest that blanids are more primitive, and are either related to Bipes or represent an even more ancient lineage.A number of fossils from Europe have been referred either to Blanus or to the Blanidae.


Charmosyna is a genus of parrot in the family Psittaculidae.

It contains the following species:

Josephine's lorikeet (Charmosyna josefinae)

Duchess lorikeet (Charmosyna margarethae)

Meek's lorikeet (Charmosyna meeki)

Striated lorikeet (Charmosyna multistriata)

Palm lorikeet (Charmosyna palmarum)

Papuan lorikeet (Charmosyna papou)

Red-flanked lorikeet (Charmosyna placentis)

Fairy lorikeet (Charmosyna pulchella)

Red-chinned lorikeet (Charmosyna rubrigularis)

Pygmy lorikeet (Charmosyna wilhelminae)

†? New Caledonian lorikeet (Charmosyna diadema) (possibly extinct, 20th Century?)

Red-throated lorikeet (Charmosyna amabilis)

Blue-fronted lorikeet (Charmosyna toxopei)


Cnemidophorus is a genus of lizards in the family Teiidae. Species in the genus Cnemidophorus are commonly referred to as whiptail lizards or racerunners. The genus is endemic to South America, Central America, and the West Indies.


Dendrobates is a genus of poison dart frogs native to Central and South America. Dendrobates once contained over 40 species, but most species originally placed in Dendrobates have been split off into the genera Oophaga, Ranitomeya, Andinobates, and Phyllobates.

The generic name Dendrobates is derived from the Greek words δένδρο dendron "tree" and βατῷ bato "I mount", meaning ‘tree climber’.

Gray gecko

The gray gecko (Sphaerodactylus cinereus) is a species of lizard in the family Sphaerodactylidae . It is endemic to Haiti.


Guttera is a genus of birds in the Numididae family. Established by Johann Georg Wagler in 1832, it contains two species:

Plumed guineafowl, Guttera plumifera

Crested guineafowl, Guttera pucheraniThe name Guttera is a combination of the Latin words gutta, meaning "spot" and -fera, meaning "bearing" (from ferre: to bear).The two species are found in forests of sub-Saharan Africa. Unlike other guineafowl, they have a distinctive black crest.

Helicops (genus)

Helicops is a genus of snakes of the family Colubridae. The genus is endemic to South America.


For the hydrozoan Cnidaria called "Hydromedusa" or "Hydromedusae", see Anthomedusae.

Hydromedusa is a turtle genus in the family Chelidae, commonly known as the South American snake-necked turtles. They are quite closely related to the South American side-necked swamp turtles (Acanthochelys) and the snake-necked turtles of the Australian-Melanesian region (Chelodina), but less closely to the spine-necked river turtles of South America (Podocnemididae) which belong to a more modern lineage of Pleurodira.


Liophis is a former genus of New World colubrid snakes. They have a wide range of nondescript and local names, among these "water snakes", "mapepires", "corals" or "racers".


Micrurus is a genus of venomous coral snakes of the family Elapidae.


Pareas is a genus of Asian snakes in the family Pareidae. All species in the genus Pareas are harmless to humans.


Sometimes called the bearded toadheads but better known by their scientific name of Phrynops this genus of turtles has often been a bit of a dumping ground for the short-necked South American turtles of the family Chelidae.

The genus is widely distributed in South America found in the Orinoco to Amazon and São Francisco to Paraná and adjacent river basins of Colombia, Venezuela, the Guianas, Brazil, Paraguay, Uruguay and northeastern Argentina (Iverson, 1992).The phrynop turtle generally achieves thermoregulation through areal basking. In order to best attain their goal, they tend to increase their basking time during mid-day during the winters to make up for the cold. Other factors such as food intake and reproduction underwater also influence the way they control the temperature of their body. Although this is the main way they are able to maintain body temperature, food intake and reproduction rates are also influential in the matter.


Phyllomedusa is a genus of frog from family Hylidae which inhabits Central and South America. It ranges from Costa Rica southward to Argentina. It has around 30 species.


Podarcis is a genus of lizards. Its members look very similar to lizards of the genus Lacerta, to which they were considered to belong until the 1970s. While similar externally and ecologically, Podarcis form a distinct group differing from Lacerta by the construction of the skull and the hemipenis, and by the processes of the caudal vertebrae. They are commonly known as wall lizards. They are native to Europe and northern Africa, and most species are restricted to the Mediterranean region. The Italian wall lizard and the common wall lizard have been introduced to North America.


Podocnemis is a genus of aquatic turtles, commonly known as South American river turtles, in the family Podocnemididae. The genus consists of six extant species occurring in tropical South America. Three additional species are only known from fossils.


Scinax is a genus of frogs (snouted treefrogs) in the family Hylidae found in eastern and southern Mexico to Argentina and Uruguay, Trinidad and Tobago, and Saint Lucia. These are small to moderate-sized tree frogs, drably colored. Duellman and Wiens resurrected this genus in 1992. The name originates from the Greek word skinos, meaning quick or nimble.

Shiny guinea pig

The shiny guinea pig (Cavia fulgida) is a guinea pig species of southeastern South America.

The rodent is endemic to Brazil and Argentina. It is native to the Atlantic Forest ecoregions.


Staurotypus is a genus of aquatic turtles, commonly known as giant musk turtles, Mexican musk turtles, or three-keeled musk turtles, in the family Kinosternidae. The genus contains two recognized species, which are endemic to Mexico and Central America.


Zamenis is a genus of Old World nonvenomous snakes in the family Colubridae.
