| Summary: | Тhe fauna of Tingidae (Hemiptera:
Heteroptera) of the North Caucasus includes 59 native
species of 19 genera and one invasive species. Тhis fauna
consists of two large and not equivalent zoogeographical
complexes of a different origin. The main body of the fauna
is formed by arid complex, in the wide sense, including 44
species (74.6% of all Tingidae native fauna of the North
Caucasus). The most part of species areas of this complex
is located on territory of the Ancient Mediterranean. The
complex includes the following zoogeographical elements:
subarid wide palaearctic (20 species, or 33.9% of all Tingidae
fauna), mediterranean with great prevalence of originates
from dry subtropics (15 species; 25.4 %), subarid west
palaearctic (5 species; 8.5%), deserted-steppe (3 species;
5.1%), tropic-subtropical of the Old World (1 species;
1.7%). Species of this complex inhabit open biotopes of
the flat part of the North Caucasus and good isolated parts
of slopes and forest edges of low mountains and rarely
somewhat more lofty.
A humid zoogeographical complex is in 3 times
smaller on volume (15 species; 25.4%) than arid one. The
bigger or considerable part of species areas of this complex
is outside of area of the Ancient Mediterranean. In arid
part of Palaearctic they inhabit biotopes intrazonal type
and not arid lots of mountains slopes. Some species of this
complex rise up to altitude of 2000 m. The majority of these
species are very widespread in a longitudinal direction, a
part of species have the transpalaearctic distribution or
almost that. Unique endemic of Caucasus and Pontian
mountains, Stephanitis caucasica Kiritshenko, 1951, enters
into this complex of the North Caucasus fauna. There
are two tertiary relicts into the North Caucasus fauna –
Cantacader quadricornis (Lepeletier et Serville, 1828) and
Stephanitis caucasica |
