The first record of Hebius vibakari (Colubridae: Natricinae) in Pogranichny District, Primorsky Krai

Hebius vibakari (Boie, 1826) is a poorly studied snake species native to the Russian Far East. In early August 2024, an adult specimen of this elusive species was found and photographed by the present author in the Studenaya River valley, near the village of Dukhovskoe. The snake was found hiding beneath a flat stone on the river bank. This report is the first confirmed record of the Japanese keelback from Pogranichny District, which contributes to our understanding of Hebius vibakari distribution in Primorsky Krai.
