Syncosmetus japonicus Sharp, 1891 ( Figs 11 , 136–138 , 142A, 143A, 144–145 )

Omogocis tuberculifrons Miyatake, 1954 (synonymised by Miyatake 1970)

Diagnosis and comments

The species differs from Syn. reticulatus by the more convex and oval body ( Figs 136–138 ), with more marked keels and larger punctation on elytra. The male genitalia ( Fig. 144 ) is well sclerotized, with a cylindrical median lobe that is longer than the tegmen and as long as the ninth segment. The basal piece is distinct, with almost half the length of tegmen, the anterior margin broadly rounded and the posterior margin truncate. Specimens examined

FIGURES 9–12. Female terminalia, showing the gonostyli (gs), gonocoxites (gc), baculi of basal gonocoxites (small arrows), paraprocts (pp), baculi of paraprocts (b.pp), proctiger (pt), and spiculum ventrale (sv). The baculi of proctiger are barely sclerotized, so they are not indicated. 9. Xylographella punctata Miyatake. 10. Scolytocis furieriae sp. nov. 11. Syncosmetus japonicus Sharp. 12.
