Pseudonaja modesta , called Ringed Brown Snake in English, is a species of snake from the family of poisonous snakes (Elapidae) and belongs to the genus of brown snakes ( Pseudonaja ). There are noknown subspecies .
features
Pseudonaja modesta reaches a total length of 40 to 60 cm. The body is slim. The head is relatively short and hardly separates from the neck. The eyes are relatively large and have a round pupil when exposed to light. The body has an olive, light brown or reddish brown basic color. The body scales are smooth and not keeled. There are four to twelve black transverse bands along the back, which are far apart. The spots extend in width over one to five scales. In older specimens, the transverse ties may be faded or no longer exist. The tip of the head, the front top of the head and the nape of the neck are colored dark gray to black. The inside of the mouth is black.
As is typical for venomous snakes, the venom apparatus consists of venom glands located on the side of the skull (specialized salivary glands ) and immobile fangs located in the anterior upper jaw (proteroglyphic tooth position).

distribution
The distribution area includes areas within Australia in New South Wales , Northern Territory , Queensland , South Australia and Western Australia . The populated habitats are represented by bush and grasslands, Spinifex- stocked areas and agricultural areas. In the distribution area there is a semi-arid to arid climate . Pseudonaja modesta is considered stable and not endangered in its population.
Way of life
Pseudonaja modesta leads a diurnal and largely soil-dwelling way of life. In the heat of the day, especially in the northern areas of the distribution area, it shifts its activity phase to twilight and night. Animal structures, wood and the like serve as hiding places. The range of prey primarily includes small reptiles (geckos, skinks). The propagation is done by oviparity so oviparous. The clutch contains up to 11 eggs.
Snake venom
The poison secretion of Pseudonaja modesta probably contains neurotoxins and substances that influence hemostasis (procoagulants). In contrast to some other pseudonaja species, the venom bite is usually not considered to be medically significant for humans. Clinical attention should be paid to coagulopathy and kidney damage after a poison bite . In the case of severe complaints, Antivenins are available ('Polyvalent Snake Antivenom (Australia - New Guinea)' and 'Brown Snake Antivenom' from the manufacturer CSL Limited ).
