Beetles. Lopatin I. K. — F new species of leaf beetles of the Central Asian genus Oreomela Jacobson
is described from the Saur Range (eastern Kazakhstan). Numerous species of this genus are wingless
and occur in mountain systems of Tien Shan, Pamiro-Alai, Hindu Kush, Xinjiang and Tibet, being
characteristical and common on alpine meadows. O. dolini sp. n. is similar to O. korolkovi Jacobson
from the Dzhungar Alatau Mountains in the punctuation on elytra disc partially forming rows, differ-
ing by thickened joints of short antenna, sparse punctuation on head and shape of edeagus.
Êëþ÷åâûå ñëîâà: Coleoptera, Chrysomelidae, new species, Kazakhstan, Saur Mt. Ridge.
