Question: What type of species is a Boreo-arctic Montane species found in the most northerly of the abstract five major circles of latitude as shown on maps of the Earth?

Context paragraphs:
Geographical zone: The five main latitude regions of the Earth's surface comprise geographical zones, divided by the major circles of latitude.  The differences between them relate to climate.  They are as follows:

Carabus glabratus: Carabus glabratus is a species of beetle.  It is a Boreo-arctic Montane species widespread in Central Europe and Northern Europe north to the Arctic Circle.

Smerinthus minor: Smerinthus minor (lesser eyed hawkmoth) is a moth of the family Sphingidae.  It was described by Mell in 1937.  It is a montane species found from the Taibai Shan area, western Qinling Mountains in Shaanxi, China eastwards along the Qinling to southern Shanxi and then north to just west of Beijing.  It has also been recorded from the Miaofeng Mountains near Beijing and the Wuling Mountains in Hunan.

Ulmus glabra: Ulmus glabra, the wych elm, Scotch elm or Scots elm, has the widest range of the European elm species, from Ireland eastwards to the Urals, and from the Arctic Circle south to the mountains of the Peloponnese in Greece; it is also found in Iran.  A large, deciduous tree, it is essentially a montane species, growing at elevations of up to 1500 m, preferring sites with moist soils and high humidity.  The tree can form pure forests in Scandinavia and occurs as far north as latitude 67°N at Beiarn in Norway.  Wych elm has also been successfully introduced to Narsarsuaq, near the southern tip of Greenland (61°N).

Arctic Circle (disambiguation): Arctic Circle is one of the five major circles of latitude that mark maps of the Earth.

Porthecla peruensis: Porthecla peruensis is a butterfly in the Lycaenidae family.  It is found in northern Peru, on the east side of the Andes.  It appears to be a montane species, since it has only been found at altitudes above 1,500 meters.

Amietia wittei: Amietia wittei (common name: Molo frog) is a species of frog in the Pyxicephalidae family.  It is found in Kenya, Tanzania, and eastern Democratic Republic of the Congo.  Its type locality is in Molo, Kenya, located near the top of the Mau Escarpment.  It is a common species associated with montane grasslands, perhaps forests, and also found in a town.  It is found in the Kenyan central highlands and northern Tanzania in the East African montane moorlands and the East African montane forests ecoregions.

Antarctic Circle: The Antarctic Circle is the most southerly of the five major circles of latitude that mark maps of the Earth.  The region south of this circle is known as the Antarctic, and the zone immediately to the north is called the Southern Temperate Zone.  South of the Antarctic Circle, the sun is above the horizon for 24 continuous hours at least once per year (and therefore visible at midnight) and (at least partially) below the horizon for 24 continuous hours at least once per year (and therefore not fully visible at noon); this is also true within the equivalent polar circle in the Northern Hemisphere, the Arctic Circle.

Arctic Circle: The Arctic Circle is the most northerly of the abstract five major circles of latitude as shown on maps of the Earth.  It marks the northernmost point at which the noon sun is just visible on the northern winter solstice and the southernmost point at which the midnight sun is just visible on the northern summer solstice.  The region north of this circle is known as the Arctic, and the zone just to the south is called the Northern Temperate Zone.  North of the Arctic Circle, the sun is above the horizon for twenty-four continuous hours at least once per year (and therefore visible at midnight) and below the horizon for twenty-four continuous hours at least once per year (and therefore not visible at noon); this is also true within the equivalent polar circle in the Southern Hemisphere, the Antarctic Circle.

Nepenthes attenboroughii: Nepenthes attenboroughii ( or ), or Attenborough's pitcher plant, is a montane species of carnivorous pitcher plant of the genus "Nepenthes".  It is named after the celebrated broadcaster and naturalist Sir David Attenborough, who is a keen enthusiast of the genus.  The species is characterised by its large and distinctive bell-shaped lower and upper pitchers and narrow, upright lid.  The type specimen of "N. attenboroughii" was collected on the summit of Mount Victoria, an ultramafic mountain in central Palawan, the Philippines.
