Diagnosis

Recognized by its moderate size; dorsum dark brown to fuscous (in males), and paler (in females) and rather glabrous, covered with sericeous setae (Fig. 1 A, B); pronotum immaculate and glabrous, pale line transverse vertically along medial part of pronotum; cuneus pale, apex darkened; basal half of metafemur pale, distal half dark brown to fuscous; male genitalia as in Fig. 2 A, B and Fig. 3 C, D; spiculum distinctly long and slender (Fig. 2 B); sensory lobe of left paramere rather tumid; sclerotized ring small and ovate, semicircular (Fig. 4 A, B). For detailed diagnostic character, figures and description, see Yasunaga (1998).

Distribution

China (Fujian, Hebei, Sichuan) ( Zheng et al. 2004), Japan (Hokkaido, Honshu), Far East Russia (S. Primorskij Prov.) ( Yasunaga 1998), Korea (Central, New record).

Notes

This species is host specific to Juglans spp. and Pterocarya rhoifolia Siebold & Zucc. ( Juglandaceae ) ( Yasunaga 1998). Yasunaga (1998) assumed Japanese C. falkovitshi invaded from Primorskij, Russia, via the Korean peninsula. Our record supports this hypothesis.
