Abstract The first record of Margaritapion nitrariae (Ter-Minassian, 1970) (Brentidae: : Aplemonini) from Altaiskii Krai, Western Siberia, Russia is given. It is the most north-eastern find of this species. The redescription of Margaritapion nitrariae is completed. A key for identifying Margaritapion Korotyaev, 1990 and similar genera is given.

Key words: , Curculionoidea, Apioninae, Aplemonini, new record, Siberia.

Introduction

The subfamily Apioninae is a diverse group including more than 2200 species and subspecies (Alonso- Zarazaga and Wanat 2014) from 25 tribes (Legalov 2018). The tribe Aplemonini includes 15 genera distributed mainly in Eurasia less often in North America and Africa (Alonso-Zarazaga and Lyal 1999). This tribe is characterized by the elytral stria 10 is absent, the procoxal cavities are completely separated, long trochanters, contiguous mesocoxae and the pygidium is of the apionine type (Legalov 2018). The genus Margaritapion Korotyaev, 1990 was described (Korotyaev 1990) for the species is associated with Nitraria (Ter-Minassian 1970). This species was found from Turkey (Korotyaev and Gültekin 2002; Korotyaev et al. 2016), Turkmenistan (Krivokhatsky 1985), Southeast Kazakhstan and Mongolia (Korotyaev 1990). Margaritapion nitrariae is collected from the south-west of Altaiskii Krai during the study of Coleoptera is associated on Nitraria. It is the first record from Russia and the most north-eastern find of this species.

FIRST RECORD OF MARGARITAPION NITRARIAE FROM RUSSIA

Material and methods

Studied specimens are kept in the ISEA – Institute of Systematics and Ecology of Animals (Russia: Novosibirsk), CSRN = the private collection of S.V. Reshetnikov (Novosibirsk) and Zoological Institute RAS (Saint-Petersburg). ‚ Photographs (Figs. 1, 3−4) were taken with a camera Fujifilm X-T10 by S.V. Reshetnikov (Novosibirsk). Descriptions, photographs (Fig. 2) and body measuring were performed using a Zeiss Stemi 2000-C dissecting stereomicroscope. The terminology of body is according to Lawrence et al. (2010) and Alonso-Zarazaga (1990). The systematics of studied taxa are based on Alonso-Zarazaga et al. (1999) and Legalov (2018).

Mesorostrum slightly dilated in both sexes. Antennal scrobes deep, long, directed to under rostrum. Forehead slightly flattened, slightly wider than rostrum base. Eyes large, rounded, not protruding from contour of head. Temples short. Antennae straight, inserted ventrally in basal one third of rostrum, rather short, reach apex of pronotum. Funicle 7-segmented. Antennomere 1 elongate-trapezoidal, about 2.7 times as long as wide. Antennomere 2 elongate-oval, about 1.4 times as long as wide, shorter and wider than antennomere 1. Antennomeres 3-5 rounded. Antennomeres 6-8 transverse. Club compact, 0.7 times as long as antennomeres 2-8 combined. Pronotum almost campaniform, 1.4 times as long as wide at apex, subequal to wide in middle and slightly shorter than wide at base. Greatest width before middle. Vestiture centriptenal. Scutellum almost square, small. Elytra back pear-shaped, distinctly convex, about 2.0 times as long as base width, 1.3 times as long as wide in middle, 1.5 times as long as wide in apical quarter, 2.5 times as long as pronotum. Greatest width in apical one third. Humeri weakly flattened. Striae distinct and deep. Elytral stria 10 absent. Interstriae wide, slightly convex. Elytral apices rounded separately. Pre- and postcoxal portions of prosternum short. Postcoxal portion distinctly longer than precoxal portion. Pro- and mesocoxal cavities rounded. Procoxal cavities completely separated. Mesocoxal cavities separated. Metasternal apophysis triangular. Metacoxal cavities transversely extended. Metaventrite 1.5 times as long as metacoxa. Ventrites 1 and 2 equal in length, convex. Ventrite 1 slightly shorter than metacoxal width. Ventrites 3–5 flat, positioned in different plane than ventrites 1 and 2. Ventrites 3 and 4 equal in length.
