Etymology

This new species is named for Alexander Konstantinov, an outstanding Chrysomelidae  researcher, in gratitude for the loan of many interesting specimens of Neocrepidodera  and his always helpful advice.

Diagnosis

Length = 3.3–3.7 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 markedly transverse, distinctly asymmetrical, rounded anteriorly and angulose posteriorly. Surface covered with coarse punctures on disc, minute on basal region, with only a few slightly greater punctures in antebasal transverse groove ( Fig. 4View FIGURES 1 – 6). Elytra: punctation completely seriate. Punctures large but relatively shallow, almost effaced to the apex. Interstriae flat and broader than striae. Base of sixth elytral stria impressed slightly deeper than the remaining striae. Aedeagus: strongly expanded in the apical fourth in ventral view, apex rounded, forming a poorly developed denticle, strongly deflexed ventrad in lateral view ( Fig. 10View FIGURES 7 – 12). Vaginal palpus: relatively short and thin, almost straight, tapering to the apex ( Fig. 16View FIGURES 13 – 18 a). Spermatheca: as in Fig. 16View FIGURES 13 – 18 b.

Description

Length = 3.3–3.7 mm. Body convex, about two times longer than wide. Colour yellowish brown. Head: slightly convex. Labrum bearing three pairs of setae in anterior margin. Clypeus bearing 4 pairs of long setae in anterior margin and many other shorter ones. Frontal ridge between antennal calli wide and flat. Antennal calli oval and flat, not distinctly delimited from vertex. Vertex smooth and shiny, with a strong deep seta­bearing puncture near each eye. Third antennomere about 1.5 times longer than second, equal or slightly shorter than fourth and shorter than fifth. Pronotum: 1.4 times broader than long, widest at middle, constricted basally, narrowly margined, provided with an antebasal transverse furrow delimited laterally by two longitudinal impressions. Anterolateral callosity markedly transverse, distinctly asymmetrical, rounded anteriorly and angulose posteriorly. Surface covered with coarse punctures on disc, minute on basal region, with only a few slightly greater punctures in the antebasal transverse groove ( Fig. 4View FIGURES 1 – 6). Elytra: moderately convex, about 1.3 times longer than broad, widest at middle. Humeral callus well developed, macropterous. Lateral margins explanate, apex rounded. Surface shiny. Punctation arranged in 10 distinct striae, scutellar stria short. Punctures large but relatively shallow, almost effaced to the apex. Interstriae flat and broader than striae. Base of sixth elytral stria impressed slightly deeper than the remaining striae, delimiting interiorly the humeral callus. Aedeagus: strongly expanded in the apical fourth in ventral view, apex rounded, forming a poorly developed denticle, strongly deflexed ventrad in lateral view ( Fig. 10View FIGURES 7 – 12). Vaginal palpus: relatively short, almost straight, tapering to the apex and where they are thin ( Fig. 16View FIGURES 13 – 18 a). Spermatheca: as in Fig. 16View FIGURES 13 – 18 b.

Remarks

The new species is close to N. sublaevis Motschulsky  and N. motschulskii Konstantinov  by the elytral punctation regularly seriate and the shape of vaginal palpi. However external characters as the anterolateral callosity of pronotum or the base of sixth elytral stria, as well as the structure of aedeagus show marked differences among the three taxa.

Distribution

The new species is known from the Chinese and Russian Far East, in Heilongjiang Sheng and Ussuriiskiy Kray regions respectively. The known distribution is comprised between 129 and 132 degrees E, 42 and 45 degrees N.
