Asiodonus lobanovi Legalov & Reshetnikov, a new species of the tribe Hyperini (Coleoptera: Curculionidae) from Altai (Western Siberia)

A new species, Asiodonus lobanovi Legalov & Reshetnikov, sp. nov. from Altai is described and illustrated. It is similar to A. herteshensis (Legalov, 2008) but differs in the scapus not reaching eyes, wider elytral and pronotal scales bifid at apex, more elongated elytra, narrower rostrum, partially reddish-brown antennae, distinctly pointed and curved aedeagus

In this paper, a new species of the genus Asiodonus from Altaiskii krai is described.

Material and methods
Type specimens are kept in the ISEA -Institute of Systematics and Ecology of Animals (Russia: Novosibirsk) and CSRNthe private collection of S.V. Reshetnikov (Novosibirsk). Descriptions, body measuring were performed using a Zeiss Stemi 2000-C dissecting stereomicroscope. The photographs were taken with a camera Fujifilm X-T10.
The terminology of the weevil body is according to Lawrence et al. (2010).
Female: Rostrum 2.5 times as long as wide at apex, 2.7-2.8 times as long as wide in middle, 2.6-2.7 times as long as wide at base, 0.8 times as long as pronotum. Pronotum 1.3 times as long as wide at apex, 0.8-1.0 times as long as wide in middle, 0.9 times as long as wide at base. Elytra wider, 1.9 times as long as wide at base, 15-1.6 times as long as wide in middle, 2.6-2.9 times as long as wide at apex, 3.1-3.4 times as long as pronotum. Abdomen convex. Ventrites 1 and 2 without depression in middle.

Differential diagnosis.
The new species is similar to A. herteshensis from East Sayan Mountains but differs in the scapus not reaching eyes, wider elytral and pronotal scales bifid at apex, more elongated elytra, narrower rostrum, partially reddish-brown antennae, distinctly pointed and curved aedeagus. It differs from Asiodonus opanassenkoi (Legalov, 1997) in the body covered with scales, larger body sizes, and long aedeagus with elongated apex.   Distribution. The new species are described from the Korgon mountain range, Altai Mountains (Figure 3), while a species closely related to it lives on the Akademika Obrucheva Mts, East Sayan Mountains ( Figure  3).
