Vipera darevskii in the field. Age variability. Newly born vipers are uniquely colored. Geographic range and ecology. The species range shows relict characters. It covers the southeast part of the submeridian Dzhavakhetsky Ridge within the territory of Armenia (here this ridge has the name Mokrye (Wet) Mountains) and evidently adjacent regions of Georgia (Fig. 1: 9). Vertical distribution lies within a narrow interval at elevations from 2600 (rarely 2500) to 3000 m on Mount Legli, Georgia. It is a montane meadow subalpine species inhabiting detritus slopes with great amounts of big black outcrops of volcanic rocks at angles of 35°-45° (Darevsky pers. comm.). At recorded elevations, according to Tumadzhanov (1980), subalpine meadows (so called Transcaucasian oats outcrops) are widely represented. It is a leading formation on steep slopes with all exposures which form the first stages of invasion of bare rock outcrops. Characteristic components of these meadows are as follows: Festuca woronowii, F. ovina, Bromopsis variegata, B. villosula, and Carex tristis. Lower along the slopes at elevations from 2300 to 2400 m the formations of transition montane-meadow steppe are replaced by montane Festuca valesidea and Stipa (feather grass). From elevations of 2200 m down to 1000 m Festuca valesiaca steppes occur (Lavrenko 1980). Here in the montane-steppe highland ecological belt, Vipera ursini eriwanensis occurs in contact with V. darevskii in the transition zone of the meadow steppes. The numbers of Vipera darevskii are not great. To date it is known only from the type locality cited as "Mount Legli", where it occurs within a narrow band in subalpine meadows.
