Neocrepidodera motschulskii ( Konstantinov, 1991)

( Figs. 6 , 12 , 18 )

Asiorestia motschulskii Konstantinov, 1991: 143

Material examined

RUSSIA: Primorskiy Kray, Ussuriiskiy National Park, 27 July 1985, 1 ex. (Pisanenko leg.); 2 August 1985, 2 ex. (Pisanenko leg.).

Diagnosis

Length = 3.0–4.1 mm. Head: frontal tubercles not distinctly delimited posteriad, supracallinal sulcus effaced. First antennomere distinctly shorter than second and third together. Pronotum: constricted basally, narrowly margined. Anterolateral callosity rounded, well developed and almost symmetrical. Surface covered with coarse punctures on disc and minute ones on basal region, with greater punctures in the antebasal transverse groove ( Fig. 6 ). In some specimens these strong punctures extend almost to the base, but there is always a basal strip covered with minute punctures. Elytra: punctation completely seriate, or sometimes with some striae partially irregular because some punctures are duplicated or slightly disordered (especially in females). Punctures large and deep. Interstriae slightly convex and slightly wider than striae. Base of sixth elytral stria strongly impressed, deeper than the other striae. Aedeagus: produced apically into a very acute point in ventral view ( Fig. 12 ). Vaginal palpus: long, slightly curved and slightly tapering to the apex, basal membranous region long ( Fig. 18 a). Spermatheca: as in Fig. 18 b.

Distribution

North and Central Europe, reaching France to the South, Turkey, Caucasus, Tajikistan, Russian Far East (this paper). Present records are a major range extension for N. motschulskii , because previous easternmost records were from Tajikistan ( Gruev & Döberl 1997).
