Taxonomy
editOmmatotriton ophryticus was speculated to be a subspecies of O. vittatus, the southern banded newt, until 2005, when Litvinchuk and co.[4] raised it to full species' status.[2] They had also described a newer subspecies under this taxon, at the time, Triturus ophryticus nesterovi,[4] which is now recognized as a separate species: O. nesterovi, the Anatolian banded newt.[2]
Description
editThe tail is about the same length as the body and head. The limbs and digits are long, more so in males. Skin is almost smooth to slightly granular. During the terrestrial phase, the dorsum is reddish. During the aquatic phase, the dorsal and lateral surfaces are bronze-olive or olive-brown; there are small dark points on the back and a light band on flanks bordered with dark stripes. The belly is immaculate yellow to orange. During the breeding season, adult males develop very high and notched middorsal and caudal crest; the colouration is yellowish or brownish, with dark vertical stripes. Furthermore, their tails are covered with dark spots from above and with blue and/or greenish spots elsewhere.[3]
Habitat and conservation
editOmmatotriton ophryticus occurs mostly higher than 1,200 m (3,900 ft) above sea level.[3] It typically lives in coniferous, mixed, and deciduous forests, up to subalpine meadows.[1][3] Reproduction takes places in a large range of water bodies, from temporary ponds to lakes.[1] Hibernation generally takes place on land, although individuals in breeding colours have been found in water as early as January. The terrestrial habitat may be relatively arid.[3]
Ommatotriton ophryticus can be locally common, but it is sporadically distributed over much of its range. It suffers from habitat loss caused forest destruction, dam construction, destruction of wetlands, overgrazing by cattle, urbanization, and pollution. Also predation by introduced raccoons (Procyon lotor) is a major threat. It is also collected for pet trade.[1]
