Syncosmetina Lopes-Andrade subtr. nov. ( Figs 7–8 , 11–12 , 136–159 )

Included genera

Syncosmetus Sharp, 1891 (type genus)

Tropicis Scott, 1926

Diagnosis

This new subtribe is characterized by the combination of the following characters: (i) lateral pronotal carina always crenulated; (ii) pronotal and elytral punctation very coarse and dense, punctures coalescent in some portions; (iii) scutellum inconspicuous, its basal width less than 0.10X the greatest elytral width; (iv) elytra bearing longitudinal keels in most species; (v) prosternal process broad; (vi) procoxae cylindrical, at the same level of the prosternal process; (vii) apex of prementum rounded.

Distribution

Syncosmetina subtrib. nov. is known to occur in parts of the Afrotropical (restricted to the western Indian Ocean; Tropicis ) and Palearctic (restricted to Japan; Syncosmetus ) Regions.

Figures

FIGURES 5–8. Prementum (pm) with labial palpi (l.p). Note that the apical labial palpomeres are enlarged (small arrows), and that the apex of prementum is acute in Xylographella and Scolytocis, and rounded in Syncosmetus and Tropicis (see big arrows). 5. Xyl. punctata Miyatake, lateral view. 6. Scol. paschoali sp. nov. 7. Sync. reticulatus Miyatake. 8. Trop. sexcarinatus (Waterhouse).

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.
