( Figs. 2 , 8 , 14 )

Crepidodera obscuritarsis Motschulsky, 1859: 498 Crepidodera lewisii Jacoby, 1885: 721

Asiorestia obscuritarsis: Gressit & Kimoto, 1963: 767 Diagnosis

Length = 4.5–6.0 mm. Head: frontal tubercles not distinctly delimited posteriad, supracallinal sulcus effaced. First antennomere distinctly shorter than second and third together. Pronotum: transverse, slightly constricted basally, narrowly margined. Anterolateral callosity transverse, distinctly asymmetrical, rounded anteriorly and toothed posteriorly. Surface covered with minute punctures on disc and basal region ( Fig. 2 ). Elytra: punctation almost completely confused because striae are irregular double or triple rows of punctures broader than interstriae, only basal region of striae more recognizable. Punctures small and shallow, interstriae completely flat. Base of sixth elytral stria not impressed, very slightly deeper than the other striae. Aedeagus: very large, strongly constricted anteapically in ventral view, produced into a denticle at apex ( Fig. 8 ). Va gi n al palpi: long and slender, moderately curved ( Fig. 14 a). Spermatheca: as in Fig. 14 b.

Distribution

Far East, North East China, Japan.
