Question: Pseudechis includes the snake that is found in what country?

Context paragraphs:
Blue-bellied black snake: Pseudechis guttatus (the blue-bellied black snake or spotted black snake) is a species of black snake that is only found in the inland areas of south-eastern Queensland and northern New South Wales.  On average, their measurement is 1.25 m, but some snakes have been found to measure as long as 2 m.  Their diet consists of frogs, lizards, and small mammals, therefore making them carnivorous.  They, like most other snakes, are oviparous, laying 7–12 eggs during their breeding season.  It is unknown what their average venom ejection is.  When mice are bitten, the snake's venom is the most toxic of all the black snakes.  They are naturally very shy, and will not bite unless provoked (by being stepped on by a boot, prodded by a stick, etc.).  If a human is bitten, they may suffer severe pain, nausea, vomiting, diarrhoea, diaphoresis and regional lymphadenopathy at the location of the bite, similar to a red-bellied black snake's bite symptoms.  Bites are infrequent.  If bitten, tiger snake antivenom is the preferred treatment.

Papuan black snake: The Papuan black snake ("Pseudechis papuanus") is a venomous snake of the family Elapidae native to New Guinea.

Collett's snake: The Collett's snake ("Pseudechis colletti") – also known as the Down's tiger snake, Collett's black snake or Colletts cobra – is a venomous snake native to Australia.  Although the Collett's snake is not as venomous as other Australian snakes, it is capable of delivering a fatal bite, ranking nineteenth in the world's most venomous snakes.

Eastern dwarf mulga snake: The eastern pygmy mulga snake ("Pseudechis pailsei") is a venomous snake of the family Elapidae native to Australia, genetically confirmed as a distinct species in 2017.

Red-bellied black snake: The red-bellied black snake ("Pseudechis porphyriacus") is a species of elapid snake native to eastern Australia.  Though its venom is capable of causing significant morbidity, a bite from it is not generally fatal and is less venomous than other Australian Elapid snakes.  It is common in woodlands, forests and swamplands of eastern Australia.  It is one of Australia's best-known snakes, as it is common in urban areas along the eastern coast of Australia.  It has an average total length (including tail) of 1.5 to .

Spotted mulga snake: The spotted mulga snake ("Pseudechis butleri") is a species of venomous elapid snake endemic to Western Australia.  It is a member of the "Pseudechis" genus, dangerously venomous snakes that can intimidate an opponent by raising the head and presenting a hood.  This cobra-like threat display is supported by the ability to produce a very large amount of venom.

Pygmy mulga snake: The pygmy mulga snake ("Pseudechis weigeli" ), also commonly known as the pygmy king brown snake, is a species of venomous snake in the black snake genus "Pseudechis" in the family Elapidae.  The species is native to Australia.

Papuan pygmy mulga snake: The Papuan pygmy mulga snake ("Pseudechis rossignolii") is a venomous snake of the family Elapidae native to Australia, genetically confirmed as a distinct species in 2017.

Pseudechis: The genus Pseudechis contains the group of elapids commonly referred to as the black snakes.  These snakes are found in every Australian state with the exception of Tasmania and some species are found in Papua New Guinea.  They inhabit a variety of habitat types, from arid areas to swampland.  All species are dangerous ("Pseudechis" signifying "like a viper", Greek "echis") and can inflict a potentially lethal bite.  Most snakes in this genus reach about 2 metres and vary in colour.  Some species are brown, where others are black.  The most recognisable and widespread species in the genus are the red-bellied black snake ("Pseudechis porphyriacus") and the Mulga snake (king brown) ("Pseudechis australis").  These snakes feed on lizards, frogs, birds, small mammals and even other snakes.  All species lay eggs, except the red-bellied black snake.  The genus "Pailsus" is a synonym of "Pseudechis", and more work is needed to understand species limits among the smaller species of the group.

Mulga snake: The mulga snake ("Pseudechis australis"), is a species of venomous snake found in Australia.  It is one of the longest venomous snakes in the world, the largest in Australia and is the second-longest in Australia (surpassed only by the coastal taipan).  Its alternative common name is "'king brown snake'", although it is a species in the genus "Pseudechis" (black snakes) and only distantly related to true brown snakes.
