TYPE MATERIAL EXAMINED. Lectotype of Haltica ivlievi (designated here): ♂ – Russia: Magadan Region, 266 km of road Palatka-Ust'-Omchuk, near Matrosovo , forest with burch and larch, 19.VII 1962, L. Ivliev [ FSCV] . Paralectotypes of H. ivlievi : 2 ♂, 1 ♀ with the same label [ FSCV] .

OTHER MATERIAL EXAMINED. Russia: Magadan Region: the same label with the same date as holotype, 3♂, 2♀, A.I. Kurentsov [ FSCV] (probably the specimens collected by Kurentsov are also belong to the type species, but in the original description only Ivliev cited as collector). Primorsky Krai: Sikhote-Alin Reserve: 12 km SW from Taezhnoye, upper section of the Serokamenka River , 45.5389ºN, 135.9850ºE, 09. VI 2017 , 1♂, M.

DIAGNOSIS. MALE. Frontal tubercles distinct, triangularly-rounded, contacted. Frontal carina narrow, sharp, high. Pronotum with small punctures, elytra with larger punctures and microsculpture. Aedeagus dorsally with transverse wrinkles formed triangle; ventrally with slightly convex medial part, with apical longitudinal ridge, apical part with short longitudinal furrow transform apically to short apical ridge; lateral furrow in basal two third wide, in third sharply limited, narrowed and deep, lateral part with sharp wrinkles transform to preapical longitudinal depression. Body length 3.9–4.2 mm.

FEMALE (hitherto unknown). Mandible ( Fig. 8 ) quadridentate, first tooth (a) clearly visible, fourth tooth (d) with distinct notch before them, fourth tooth obtuse located closer to cutting edge, proximal mandibular part strongly chitinized, mandibular condyle without tooth. Vaginal palpi ( Fig. 10 ) not parallel, distally divergented, lateral border membranous, slightly curved, distal widening short, ratio St 2 / St 1 2.33.

VARIABILITY. The coloration of the beetles and recently collected specimens is bluishgreen, but in the old collected specimens the green is disappeared and coloration became blue-violet.

HOST PLANTS. Betula сajanderi Sukacz. ( Medvedev & Roginskaya, 1988), B. platyphylla Sukacz. ( Betulaceae ) (new host plant) ( Fig. 11 ).

ECOLOGY. The species lives in white birch forests, on burnt areas with birch and larch renewal (Magadan Region), as well as in valley broad-leaved forests (Primorsky Krai, Amur Region) ( Dubeshko & Medvedev, 1989; original data). The specialized predator of A. ivlievi is the shield bug Zicrona caerulea (Linnaeus, 1758) ( Hemiptera : Pentatomidae ), as observed in Sikhote-Alin Reserve, 11. V 2018 (fig. 12).

DISTRIBUTION. Russia: Magadan oblast ( Ivliev et al., 1968; Medvedev, 1992), Primorsky Krai ( Sergeev, 2020), Amur Region (new record).

REMARKS. Altica ivlievi related with A. engstroemi Sahlberg, 1893 but differs by sharp frontal carina and by shape of frontal tubercles. Altica engstroemi develops on Betula ( Medvedev & Roginskaya, 1988) and Salix ( Matis, 1986) and occurs in Danmark, and Sweden, North and East of European part of Russia, South Ural, Northeast Kazakhstan, Eastern Siberia, Chukotka, and Kamchatka ( Lopatin et al., 2004; Warchalowski, 2010; Bieńkowski, & Orlova-Beńkovskaya, 2017). Altica ivlievi resemble A. chamaenerii (Lindberg, 1926) but differs by larger punctures of elytra ( Figs. 1 , 6 ), by sculpture of aedeagus ventrally (narrow and strong lateral preapical groove) ( Figs 3-5 ). Altica chamaenerii develops on Chamaenerion angustifolium (L.) and Salix ( Matis, 1986; Medvedev & Roginskaya, 1988) and distributed in North Europe and Mountains of Central Europe, Transcaucasia, Kyrgyzstan, Chukotka, Kamchatka ( Matis, 1986; Medvedev, 1992; Lopatin et al., 2004).
